Thunder before Summer: May 2026 Ends Spring on an Unsettled Note

May 2026 marked the final month of meteorological spring and delivered a fascinating blend of increasingly summer-like conditions punctuated by a burst of late-season thunderstorm activity. While temperatures overall aligned closely with long-term averages, the month was drier than normal and increasingly dominated by stable anticyclonic conditions, offering some of the clearest indications yet that the transition toward summer was underway.

The mean air temperature reached 19.9°C, exactly matching the climatological average. However, this apparent normality masked a subtle contrast between slightly cooler daytime temperatures and milder nights. The mean maximum temperature stood at 23.5°C, 0.4°C below average, while the mean minimum temperature reached 16.3°C, 0.4°C above normal. The warmest day of the month occurred on the 29th when temperatures climbed to 29.8°C, narrowly missing the 30°C mark and providing a brief taste of the summer heat to come. Conversely, the coolest night was recorded on the 3rd, when temperatures fell to 9.4°C, highlighting the lingering influence of springtime air masses during the first part of the month.

Humidity averaged 75.8%, slightly above normal but continuing the gradual downward trend observed since winter. Relative humidity fell as low as 41% on the 31st, reflecting the arrival of increasingly dry and warm air masses toward the end of the month.

Atmospheric pressure averaged 1017.1 hPa, 1.2 hPa above the climatological mean and the highest monthly average recorded so far in 2026. This shift marks a notable departure from the persistently below-average pressure observed during much of the preceding winter and spring, indicating a strengthening influence of anticyclonic conditions across the central Mediterranean. Pressure ranged from 1005.6 hPa on the 16th to 1025.8 hPa on the 25th.

Wind conditions remained relatively subdued. The mean wind speed was 10.5 km/h, while the northwesterly wind became the dominant direction, a classic warm-season signal across the Maltese Islands. Although ten days recorded Force 5 or stronger winds, no Force 7 or stronger events occurred during the month. The highest gust reached 49.9 km/h on the 16th.

Rainfall was scarce, with only 9.2 mm measured during the month – 5.8 mm below average. Just four rain days were recorded, two fewer than normal, reinforcing the increasingly dry character of late spring. Nevertheless, almost all the month’s rainfall occurred during a brief unsettled spell between the 15th and 17th.

Perhaps the most noteworthy aspect of May was the occurrence of three thunderstorm days, two above the climatological average despite the overall lack of rainfall. On the 16th and 17th, isolated thunderstorms developed over or near the islands, producing 4.6 mm and 3.9 mm of rainfall respectively. These storms were driven by localised instability associated with cold air aloft interacting with increasingly warm surface conditions-— a classic late-spring convective setup.

Rainfall distribution was remarkably uniform and generally low across the archipelago. Kerċem recorded 9.2 mm, the highest total among the observing stations, while several localities in Malta received less than 5 mm. The national mean stood at just 5.2 mm, highlighting how limited precipitation was across the islands.

Despite the dry conditions, cumulative rainfall since 1 September reached 545.5 mm, maintaining a healthy 25.7 mm surplus above average by the end of May. The substantial rainfall accumulated earlier in the hydrological year continued to offset the deficits observed during late spring.

A Calmer but Mild April Signals Spring’s Gradual Arrival Across the Maltese Islands

April 2026 marked a notable shift toward more settled springtime conditions across the Maltese Islands, with lighter winds, fewer disturbances and reduced rainfall compared to the preceding months. Nevertheless, the atmosphere remained somewhat humid and weakly cyclonic, while temperatures stayed slightly above seasonal norms overall.

The mean air temperature reached 16.8°C, which is 0.4°C above the climatological average. Unlike the pronounced winter warmth observed earlier in the year, April’s anomaly was more modest and primarily driven by elevated daytime temperatures. The mean maximum temperature stood at 20.6°C (+0.8°C), while the mean minimum of 13.0°C aligned exactly with the long-term norm. The month’s warmest day occurred on the 11th, when temperatures climbed to 26.3°C under notably dry air, marking the first distinctly early-summer-like conditions of the year. In contrast, the coolest day was recorded on the 1st, when the maximum reached only 14.1°C under unsettled weather associated with a deep low-pressure system.

Humidity remained relatively elevated for the season, averaging 78.9%, though this represented a slight reduction compared to previous months. Particularly notable was the sharp drop to 25% relative humidity on the 11th, coinciding with the month’s highest temperature and likely associated with a dry continental airflow. This created one of the driest air masses experienced so far in 2026.

Atmospheric pressure averaged 1014.5 hPa, remaining 1.8 hPa below normal, suggesting that while spring anticyclonic conditions became more frequent, cyclonic influence had not entirely disappeared from the central Mediterranean. Pressure ranged from a deep 993.0 hPa on the 1st – the lowest pressure observed so far in 2026 – to 1026.9 hPa on the 6th during a more stable interval.

Wind conditions eased considerably compared to February and March. The mean wind speed fell to 9.0 km/h, reflecting the gradual weakening of the winter pressure gradient across the region. Westerly winds were most frequent during the month, suggesting continued Atlantic influence at times, though without the intensity observed earlier in the season. Only eight days recorded Force 5 or stronger winds, including one Force 7 day. The strongest gust reached 49.9 km/h on the 12th.

Rainfall totals were close to average overall. A total of 18.6 mm was measured during the month, slightly above the climatological mean by 1.6 mm, while exactly 6 rain days were recorded – matching the seasonal norm. However, nearly all precipitation occurred during the opening days of the month. Between the 1st and 3rd alone, 17.7 mm fell, accounting for over 95% of April’s total rainfall. Thereafter, conditions became markedly drier, with only isolated light rain and dewfall events recorded.

The wet start to the month was linked to a deep Mediterranean depression centered near the region on the 1st, producing showers and the month’s highest 24-hour rainfall total of 9.2 mm. Despite the unsettled opening, convective activity was notably subdued overall. No thunderstorm or hail days were recorded during April, highlighting the absence of significant atmospheric instability and suggesting that frontal systems affecting the islands were relatively weak and shallow in vertical development.

Rainfall distribution across the islands was fairly uniform, though slightly lower totals were observed in southeastern coastal localities such as Valletta (8.5 mm) and Żejtun (8.2 mm). Higher accumulations occurred in Għajnsielem (21.6 mm), Marsalforn (20.6 mm), and Nadur (19.6 mm), though spatial contrasts were considerably weaker than during the winter months.

Cumulatively, rainfall since 1 September reached 536.3 mm, maintaining a 31.5 mm surplus above the long-term average despite the generally subdued precipitation patterns of late winter and early spring.

Colder than Winter in March 2026

March 2026 marked a clear transition away from the anomalous warmth of mid-winter, with temperatures easing back toward – and slightly below – seasonal norms, while humid and unsettled conditions persisted across the Maltese Islands. In fact, March was cooler than the preceding three months of meteorological winter.

The mean air temperature stood at 13.6°C, 0.4°C cooler than the climatological average. Both daytime and night-time temperatures contributed to this slight negative deviation, with a mean maximum of 16.8°C and a mean minimum of 10.4°C standing at 0.3°C and 0.5°C below the norm. This contrasts notably with the warmth observed in January and February. The warmest day of the month reached 19.7°C on the 4th, while the lowest minimum of 7.0°C was recorded on the 22nd during a cooler, drier interval.

Despite the marginally cooler thermal profile, the atmosphere remained consistently moist, with mean relative humidity at 81.7%, exceeding the long-term average by 3.6%. Frequent cloud cover and humid air masses continued to this.

Atmospheric pressure averaged 1015.1 hPa, some 2.2 hPa below normal, indicating that cyclonic influence, although weaker than in previous months, maintained a presence. Pressure ranged from 1026.9 hPa on the 4th to 997.6 hPa on the 16th, the latter associated with a more organized disturbance mid-month.

Wind patterns shifted once again, with the southeasterly direction re-emerging as dominant, suggesting a return to Mediterranean-driven airflow regimes. Mean wind speed decreased to 11.5 km/h, lower than in February, but the month remained notably breezy. A total of 19 days recorded Force 5 or stronger winds, including 11 days at Force 5, 6 days at Force 6, and 2 days at Force 7. The strongest gust reached 56.3 km/h on the 27th.

Rainfall during March amounted to 35.2 mm, slightly below the climatological mean (−5.1 mm), but with a notably higher frequency of rain days. A total of 14 rain days were recorded – five above average – indicating that precipitation was spread across multiple days rather than concentrated in significant events. The highest 24-hour total was 14.8 mm on the 14th, associated with steady rain and an isolated thunderstorm.

Convective activity was modest, with 3 thunderstorm days (slightly above average) and 1 hail day, consistent with seasonal norms. Events on the 14th–16th and again around the 23rd–24th suggest weak instability embedded within passing disturbances, rather than organized severe convection.

The rainfall distribution across the islands was relatively balanced, with a national mean of 36.8 mm. Some local enhancement was observed in areas such as Mġarr (62.4 mm), Imqabba (48.4 mm), and Buġibba (46.2 mm), while lower totals occurred in Valletta (27.5 mm) and Żabbar (25.9 mm). These variations likely reflect localized convective effects rather than strong orographic forcing, given the more variable wind regime.

Cumulatively, rainfall since 1 September reached 517.7 mm, maintaining a +30.2 mm surplus despite the slightly drier conditions in February and March. This confirms that the hydrological season remained above average overall.

March weather indicates that true settled spring conditions are yet to establish, with the atmosphere remaining dynamically active and moisture-laden.

Windy but Surprisingly Warm and Dry in February 2026

February 2026 continued the winter’s anomalously mild pattern across the Maltese Islands, though in sharp contrast to January it was significantly drier than average. The month was characterized by elevated temperatures, frequent westerly winds, suppressed rainfall totals, and persistently below-normal atmospheric pressure.

The mean air temperature clocked in at 14.6°C, which is 1.9°C above the climatological norm – an even stronger positive anomaly than January. Both daytime and night-time values reflected this. The mean maximum temperature stood at 17.1°C (+1.5°C), while the mean minimum rounded off at 12.1°C, a notable +2.4°C anomaly. The particularly strong elevation in minimum temperatures indicates sustained cloud cover and moist boundary-layer conditions limiting nocturnal cooling. The warmest day occurred on the 6th (19.4°C), while the lowest minimum of 8.0°C was recorded on the 27th during a brief anticyclonic interval.

Relative humidity averaged 82.3%, exceeding the long-term mean by 4.0%, reinforcing the impression of a persistently moist lower troposphere. Atmospheric pressure averaged 1013.2 hPa, which is 7.0 hPa below normal, confirming that cyclonic systems and Atlantic-derived disturbances remained influential across the central Mediterranean. Pressure ranged from 1028.1 hPa on the 27th – coinciding with the coolest minimum – to a deep 995.2 hPa on the 14th.

Wind conditions were a defining feature of the month. The most frequent wind direction was west, signaling a shift from January’s southeasterly dominance toward a more Atlantic-driven regime. Mean wind speed was 15.1 km/h, but several days experienced moderate to strong winds. Seven days recorded Force 5 winds, nine days Force 6, two days Force 7, and three days reached Force 8. The frequency of Force 6–8 days highlights a dynamically active month with repeated frontal passages.

Despite the active synoptic environment, rainfall totals were markedly suppressed. Only 26.5 mm of precipitation was measured, representing a deficit of 35.4 mm compared to the February mean of 61.9 mm. Rain fell on 11 days – consistent with climatological norms – but events were generally light and short-lived. The highest 24-hour total was just 7.0 mm on the 20th during a period of steady rain with distant thunder. Only one thunderstorm day and one hail day were recorded, both below average.

The rainfall regime suggests that while frontal systems affected the islands, they were either moisture-limited, fast-moving, or poorly organized locally. The predominance of a westerly flow may also have reduced orographic enhancement compared to January’s southeasterly episodes. Spatially, rainfall remained modest across the archipelago. The national mean was 21.1 mm, with slightly higher accumulations in Żurrieq (30.5 mm), Marsalforn (32.1 mm), and Imqabba (28.9 mm), and lower totals in Valletta (12.9 mm), Buġibba (13.4 mm), and Mosta (13.5 mm). The distribution was relatively even overall, reflecting the absence of prolonged convective or orographically enhanced events.

Although February itself was dry, cumulative rainfall since 1 September now stands at 482.5 mm, placing the hydrological season 35.0 mm above average by month’s end. This indicates that January’s surplus has more than compensated for February’s deficit.

January 2026 brings Significant Rainfall and Storm Harry

January 2026 was characterized by anomalously mild, humid and wet conditions. The mean air temperature, at 14.1°C, was 1.3°C above the climatological norm. This anomaly is evident in both daytime and night-time values, with a mean maximum of 16.6°C (+1.0°C) and a mean minimum of 11.5°C (+1.4°C). The warmest day occurred on the 5th (19.7°C), while the lowest minimum of the month, 4.1°C, was recorded on the 13th during a brief clearer and calmer interval.

The month was persistently moist, with mean relative humidity averaging 82%, above the long-term mean. Atmospheric pressure averaged 1011.8 hPa, a substantial 9.9 hPa below normal, reflecting frequent cyclonic incursions across the central Mediterranean and reduced anticyclonic dominance. Pressure ranged from 1028.3 hPa on the 13th to a deep 996.3 hPa on the 31st. Winds were predominantly southeasterly, with a mean speed of 14.8 km/h and a peak gust of 64.4 km/h on the 20th, consistent with repeated pre-frontal and warm-sector airflow episodes transporting moist maritime air towards the islands.

Rainfall was significantly above average. A total of 111.9 mm was measured during the month, exceeding the climate mean by 42.5 mm, while 19 rainy days were recorded – five more than normal. Since 1st September, cumulative rainfall reached 456.0 mm, confirming a wetter-than-average hydrological season to date. Spatially, precipitation totals were highest across western and elevated localities, including Mġarr (186.9 mm), Dingli (176.6 mm) and Żurrieq (166.6 mm), suggesting orographic enhancement under prevailing moist southeasterly flow. Lower totals were observed in more sheltered coastal areas such as Marsaxlokk (101.0 mm).

Two notable convective events headlined the month. On 17th January, an unusually intense hailstorm affected parts of Malta, particularly Rabat, where deep hail accumulations and localized drifts were reported. The event was associated with strong convection within a moist, unstable air mass enhanced by a relatively low freezing level and steep lapse rates, enabling efficient hail growth. Such accumulation events are rare in the Maltese Islands and indicative of vigorous updraft dynamics.

More significant was the passage of Storm Harry on 19th and 20th January, when a deep Mediterranean low developed within a broader European windstorm pattern. The system brought sustained strong southeasterly winds, heavy rainfall, thunderstorms and hail. On the 20th alone, 37.1 mm of rain was recorded — the highest 24-hour total of the month — alongside the strongest wind gust (64.4 km/h). Wind gusts of up to 100km/h were registered by several meteorological stations across the archipelago. The storm generated rough seas, coastal impacts and widespread weather-related disruption. Synoptically, the event reflected a well-developed pressure gradient and strong moisture advection ahead of the low centre, followed by the passage of a convectively active front.

Although only two thunderstorm days were recorded (below average), hail was observed on seven days, significantly above the climatological norm, indicating repeated episodes of cold upper-air intrusions and convective instability embedded within larger-scale disturbances.

2025: A Year Marked by Warmer and Wetter Conditions

Half of the year was marked by warmer than average temperatures. Four of the remaining six months registered temperatures in check with the climate norm. Two months were markedly cooler than the norm. The months closer to the norm were distributed across the second half of summer and all of autumn. In a stark contrast to the trend set in recent years, and to the relief of many, precipitation exceeded the climate norm in a total of eight months. Another month recieved rainfall in conformity with the average. The only drier than average months were January, August and November.

Overall, the year 2025 was 0.4˚C warmer than the norm. Mean maximum and mean minimum temperatures surpassed the average by 0.6˚C and 0.5˚C respectively. The early onset of upper level instability in late summer contributed towards abundant autumnal instability which in turn resulted in cooler temperatures across the region.

2025 was the first year since 2021 to register more rainfall than is expected. It was also only the fourth wetter than average year since 2010. With a total of 631.5 mm of rain, 2025 was also the wettest since 2012. The year was characterized by a good late wet winter and a long, rainy spring which extended right until the start of summer. Autumn drew a great contrast between the two islands. Downpours drenched Gozo but missed Malta almost entirely. Whilst Malta failed to enjoy a wet autumn month, the stormy weather only failed to reach Gozo in November. December was dotted with rainy days, helping it become the first one with more rainfall than the norm in eleven years! The 100 mm mark was reached on three months. The highest 24-hour rainfall total was reported on 24th September, when an afternoon isolated thunderstorm and an evening thunderstorm drenched Gozo with 60.4 mm of rain.

Almost half of all days (15) in January were characterized by at least one shower over one area or another of the Maltese Islands. Despite these days of rain, January’s total precipitation of 63.0 mm was less than the value for a typical January. Total rainfall at our weather station was an even lower 52.8 mm. Apart from being drier than the climate norm, the month was also warmer than expected at this time of year. In fact, it was among the warmest Januarys ever. The mean temperature of 14.6°C exceeded the climate average by 1.8°C. These temperatures are more typical of Easter time rather than the peak of winter! Rainfall totals bounced back in February. Whilst all corners of the Maltese Islands registered a wetter than average February 2025, it was the island of Malta which benefitted most from the rainfall recovery. Localities in Malta received approximately 103.2 mm over the course of February 2025. Gozitan localities, on the other hand, received only 65.2 mm. This was because most rain-bearing systems came to our islands with easterly currents. These affect Malta far more than Gozo. The highlight was a hailstorm with large hailstones over the southern half of Malta, particularly Birżebbuġa and Għaxaq, on Valentine’s Day. Temperatures in winter depend on the so-called polar vortex. This is a circulation of very cold air in the Arctic. This winter we’ve seen the polar vortex assume a stronger and more compact structure, leading to cold air remaining locked up and restricted to polar areas. It was so strong, in fact, that the temperature at the level of 30,000 above the Arctic dropped to -90°C (the coldest for the past 40 years).

March brought with it the dominance of Scirocco winds. A staggering 18 days were dominated by winds from the Southeasterly quadrant. Winds from these directions, referred to collectively as Scirocco are common in the springtime, but their dominance this March was greater than normal. Their prevalence impacted on the local weather in several ways. At 15.8°C, mean temperatures were a staggering 1.8°C warmer than normal. The month’s warmest temperature was measured on the evening of the 23rd. Measured at 26.8°C, this was during one of several heat bursts noted over the month. Starting soon after 18:30, the air temperature rose rapidly from around 16.9°C to 26.8°C in a space of just a few minutes. Levels of relative humidity also experienced a sharp drop, from a humid 92% to an extremely dry 40%, all in a gap of a few minutes. In typical heat burst fashion, the wind increased dramatically from a lull to gale-force in a matter of minutes. A total of 78.0 mm of rainfall was measured at our weather station in Gozo. Spread over 12 days, this rainfall continued the recovery from a dry start to the rainfall year. The plentiful rainfall was the result of successive low-pressure systems from over north Africa. Having featured only a handful of showers over two separate days, April 2025 was relatively dry until the final few days. A zone of instability coupled with cold air aloft and an absence of wind at all levels of the atmosphere allowed for the formation of an area of thunderstorms around the central Mediterranean. Gozo was affected by a series of three thunderstorms in the hours between midnight and dawn on the 29th. The extreme west, southwest and south coasts of Malta were struck by one in the morning. This made for some very loud and frequent thunder which is more often synonymous with the autumn months. Hail was also observed in some localities. This meteorological event was probably the only one thing that stood out from an otherwise normal month. May was a mixed bag of spring weather. As spring settled in across the Maltese Islands, May was characterized by a mix of pleasant weather and occasional instability, including a day of intense thundery downpours. 35.3 mm of rain was recorded at our weather station in May. This was almost four times the climate norm. A staggering 29 mm of it fell in one day. This was from a series of thundery downpours which affected all the Maltese Islands on the 15th. The 15th also accounted for the month’s highest wind gust. Copious amounts of fine desert sand were deposited by the lighter thunderstorms spread around the month.

June was off to a comfortable start. This lasted only briefly, however, as the heat of summer quickly turned up on the 7th. Large swathes of western Europe were affected by a particularly intense heat wave. In addition to this, the entire Mediterranean basin experienced an incredible lack of wind, widespread calm sea and uninterrupted blazing sunshine for much of June. June brought with it one day of rain. Rainfall was in the form of localized downpours, over the central and northern coasts of both Malta and Gozo. These showers, which affected only localized areas, lasted for a long while. Victoria, in Gozo, recorded up to 26.9 mm on that day. Other than two heat spells; one towards the beginning and another towards the end, July was relatively merciful. This could be due to an elevated relative humidity. Elevated humidity prevents temperatures from shooting up during the day. The main contributor to the greater humidity was the very warm sea. A downpour across parts of the Maltese Islands on the eve of summer solstice was also a contributing factor. Outbreaks of days with a breezy North-westerly wind also ensured that temperatures didn’t get too hot for too long. July 2025 also lived up to its expectation of being a completely dry month. No rain made it to the Maltese Islands throughout. The third and final month of meteorological summer confirmed this year’s summer as a very forgiving one temperature-wise, but rather uncomfortable with regards to relative humidity. No intense heat spells were registered over the course of the month. The days following the public holiday on the 15th lived up to their expectation of bringing to our shores some rain-bearing clouds. What started as a zone of instability over Sicily quickly spread south across the central Mediterranean. Two separate thunderstorms struck parts of the Maltese Islands: one in the afternoon hours of the 16th and another in the predawn hours of the 17th. The second thunderstorm, which struck in the dark hours, produced a beautiful display of lightning. On a separate occasion, southerly currents on the 29th brought with them overcast skies, a trace of rainfall and a dusting of desert sand.

Temperatures in the first month of meteorological autumn were around average for the time of year. September was completely dry up until the 23rd. The first wave of autumn instability arrived late and lasted for much of the final week of September 2025. The 24th and the 27th were particularly stormy; producing 97.5 mm of the 100.1 mm measured at our Gozo weather station. Whilst Gozo experienced flash flooding in the usual localities on both days, Malta was left largely untouched by the heavy downpours on those days. The thunderstorm on the 27th brought a so-called ‘microburst’ (sudden torrential rain accompanied by strong wind) to localities across the southern half of Gozo. October, the second month of meteorological autumn, was marked by a mean temperature 0.5°C below the climate norm. This can be attributed to the cooling effect of the abundant autumn rain in Gozo. October followed the rainfall pattern set in the previous month. Whilst Gozo closed off the month with a mean precipitation total of 82.1 mm, Malta lagged further behind with a tally of 62.5 mm. This discrepancy is compounded when considering totals since September 1st; Gozo’s tally standing at almost 200 mm with Malta less than half that at 78 mm! It is a well-known fact in local meteorology that Gozo is often hit harder by autumn thunderstorms than Malta. Although with a difference of just a few kilometres, Gozo lies slightly further north and is therefore more exposed to incoming storm systems from the sea. Warm waters around the island help fuel storms, and its slightly higher, more open landscape can enhance their intensity. Storm tracks frequently pass over Gozo before reaching Malta, meaning storms may weaken by the time they hit the main island. The 6 days of rain and 5 days on which thunder was heard are both short of the norm. This confirms that the fewer zones of instability which developed across the central Mediterranean were particularly intense. Whilst days of instability dotted all of November, and days of rain around the Maltese Islands exceeded the climate norm of 11 days, total precipitation was less than half the typical value for this month of the year. This could be put down to the fact that most zones of instability failed to reach a prominent level of intensity. Also, most localities missed out on a handful of downpours which developed around us. From a regional perspective, November was a fairly typical month. Localities in Malta, particularly to the south, were the recipients of a downpour on the 7th and a hailstorm on the 27th. These two rainfall events are what made a difference for a handful of localities. Hail was observed on three days. It was large and in abundance on two occasions. This can be attributed to the earlier than usual advection of cold air from the north towards the central Mediterranean. Temperatures were overall close to the norm in what is turning out to be a rather seasonal autumn.

December 2025 was the first one in eleven years to bring more rainfall than the climate norm to our shores. This rainfall was the product of three main weather systems: towards the beginning of the month, in the week before Christmas and the closing days of the year. Hailstorms on the 5th and the 31st were the month’s highlights. Central Malta was the hardest hit on both occasions. The Scirocco wind dominated the month. Standing at a mean of 18.3°C, maximum temperatures exceeded the climate norm by a significant 1.1°C. It is a direct result of warm air being advected to the central Mediterranean from north Africa. The absence of cold air incursions from northern Europe, however, meant that even the coldest night last month registered a mild minimum temperature of 9.1°C.

Plentiful Rain, High Humidity and a Dominance of Southerly Winds in December 2025

December 2025 was the first one in eleven years to bring more rainfall than the climate norm to our shores. A total of 109.1 mm was measured by our weather station. There were 12 days of measurable precipitation (> 0.1 mm) last month. Four of these, around mid-month, were the result of heavy dewfall under anticyclonic conditions. Another one was a mere drizzle on Christmas Eve. Last month’s rainfall was the product of three main weather systems: towards the beginning of the month, in the week before Christmas and the closing days of the year. Hailstorms on the 5th and the 31st were the month’s highlights. Central Malta was the hardest hit on both occasions.

A southeasterly (Scirocco) wind dominated the month. A staggering 15 days featured winds from the southeasterly quadrant (East Southeast, Southeast and South Southeast). With an overall value of 84.2%, overall levels of relative humidity reflected this reality. Standing at a mean of 18.3°C, maximum temperatures exceeded the climate norm by a significant 1.1°C. It is a direct result of warm air being advected to the central Mediterranean from north Africa. Mean minimum temperatures, on the other hand, were only a fraction of a degree above the typical value for the time of year. This could also be attributed to the cooling effect of elevated humidity levels and abundant soil moisture. The abscence of cold air incursions from northern Europe, however, meant that even the coldest night last month registered a mild minimum temperature of 9.1°C. The state of affairs would normally have cooled down substantially by the end of the year.

Another observation worth noting was the lack of exceptionally strong winds. No days with a sustained wind speed of Force 7 + were recorded last month. Northwesterly gales normally feature quite prominanelty in the first month of meteorological winter. Systems responsible for these gales were overpowered by more vigorous zones of low pressure emerging from north Africa.

Drier than Average in November 2025

Whilst days of instability dotted all of last month, and days of rain around the Maltese Islands exceeded the climate norm of 11 days, total precipitation was less than half the typical value for this month of the year. November, typically the year’s second wettest month, closed off with a poor national mean of 47.2 mm. This could be put down to the fact that most zones of instability failed to reach a prominent level of intensity. Also, most localities missed out on a handful of downpours which developed around us. From a regional perspective, November was a fairly typical month. Localities in Malta, particularly to the south, were the recipients of a downpour on the 7th and a hailstorm on the 27th. These two rainfall events are what made a difference for a handful of localities. Hail was observed on three days. It was large and in abundance on two occasions. This can be attributed to the earlier than usual advection of cold air from the north towards the central Mediterranean. Last month also helped narrow down the wide discrepancy in rainfall values between the two islands.

Temperatures were overall close to the norm in what is turning out to be a rather seasonal autumn. Colder than average nights were compensated for by typical daytime highs. The mean temperature of 17.9°C was a fraction of a degree cooler than the climate average. No temeprature extremes were recorded over the course of November 2025.

Cooler than Average; Wetter in Gozo but Drier in Malta for October 2025

October, the second month of meteorological autumn, was marked by a mean temperature 0.5°C below the climate norm. This margin was reflected in both mean maximum and mean minimum temperatures. Temperatures in Malta were notably warmer. This can be attributed to the cooling effect of the abundant autumn rain in Gozo. The surface runoff following the rainfall helps cool down the sea. The greater amount of moisture in the soil contributes to a higher humidity levels. Both help prevent the air from heating up too much. In fact, a warm spell towards the end of October registered a maximum temperature of 30°C + in Malta on the 26th. Gozo saw the temperature peak at a more comfortable 27.4°C on that same day.

October followed the rainfall pattern set in the previous month. Whilst Gozo closed off the month with a mean precipitation total of 82.1 mm, Malta lagged further behind with a tally of 62.5 mm. This discrepancy is compounded when taking into account totals since September 1st; Gozo’s tally standing at almost 200 mm with Malta less than half that at 78 mm! It is a well known fact in local meteorology that Gozo is often hit harder by autumn thunderstorms than Malta. Although with a difference of just a few kilometers, Gozo lies slightly further north and is therefore more exposed to incoming storm systems from the sea. Warm waters around the island help fuel storms, and its slightly higher, more open landscape can enhance their intensity. Storm tracks frequently pass over Gozo before reaching Malta, meaning storms may weaken by the time they hit the main island. To address a common misconception which has been floated about; while Malta’s more urbanized environment can slightly influence local wind patterns and heat, they don’t push storms away. Thunderstorms are driven by large-scale atmospheric forces, far stronger than anything urban areas can deflect. Historical data confirms that in years with a good autumn, Gozo often surpasses Malta in total rainfall. Conversely, in years with a poor autumn, Gozo often lags behind Malta. In winter and early spring, rainfall shifts to a more frontal origin. Malta, sitting slightly further south and east is more exposed to rain bands moving in from other directions. The 6 days of rain and 5 days on which thunder was heard are both short of the norm. This confirms that the fewer zones of instability which developed across the central Mediterranean were particularly intense.

Wetter in Gozo but Drier in Malta in September 2025

Temperatures in the first month of meteorological autumn were around average for the time of year. The mean temperature of 25.1°C was only a fraction of a degree above average. The slightly warmer days but slightly cooler nights contributed to this balance. The warmest day of the month, the 2nd, registered a maximum temperature 33.1°C. Temperatures declined gradually as the month progressed. Levels of relative humidity were overall higher than the norm, meaning realfeels were generally higher than the actual temperatures.

Precipitation patterns weren’t as straightforward. Last month was completely dry up until the 23rd. The first wave of autumn instability arrived late and lasted for much of the final week of September 2025. The 24th and the 27th were particularly stormy; producing 97.5 mm of the 100.1 mm measured at our Gozo weather station. Whilst Gozo experienced flash flooding in the usual localities on both days, Malta was left largely untouched by the heavy downpours on those days. Mean precipitation across Malta totalled 15.5 mm. This was very poor when compared to Gozo’s average of 103 mm. There were three rainy days. Thunder was heard on three days. Hail accompanied the afternoon thunderstorm on the 27th. The thunderstorm on the 27th brought a so-called ‘microburst’ (sudden torrential rain accompanied by strong wind) to localities across the southern half of Gozo.

September was marked by a notable absence of windy days, probably due to the intense high pressure which prevailed across the central Mediterranean for much of the month.
