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 2^nd, 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 23^rd. The first wave of autumn instability arrived late and lasted for much of the final week of September 2025. The 24^th and the 27^th 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 27^th. The thunderstorm on the 27^th 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.

Cooler than Average in August 2025

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. The mean temperature of 26.7°C stood 0.8°C below the average for this time of year. This was comprised by a mean maximum temperature of 30.3°C (1.4°C cooler than normal) and a mean minimum temperature of 23.0°C (0.3°C cooler than normal). Levels of relative humidity stood at an average of 78.1%. This made the cooler than average temperatures feel really warm. No intense heat spells were registered over the course of last month. In fact, the warmest day of the month registered a maximum temperature of ‘only’ 33.9°C. The elevated levels of relative humidity were due to a sea surface temperature which remained at 27°C + on the whole.

August was a mixed bag of spring weather. As spring settled in across the Maltese Islands, August was characterized by a mix of pleasant weather and occasional instability, including a day of intense thundery downpours. Despite the occasional unsettled spell, last month was warmer than average.

The days following the public holiday on the 15^th 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 16^th and another in the predawn hours of the 17^th. Whilst only a measly 0.5 mm of rain was measured by our weather station in Gozo, several other localities registered greater rainfall amounts. Siġġiewi and Żurrieq, for instance, measured 56.4 mm and 42.2 mm respectively. Other localities around Malta recieved half an inch of rainfall. Gozo was less affected. The second thunderstorm, which struck in the dark hours, produced a beautiful display of lightning. On a separate occasion, southerly currents on the 29^th brought with them overcast skies, a trace of rainfall and a dusting of desert sand.

Cooler Days but Warmer Nights in July 2025

Other than two heat spells; one towards the beginning and another towards the end, July was relatively merciful. The mean temperature last month was only 0.3°C above the climate norm of 27.0°C. Whilst the mean maximum temperature of 30.9°C was  0.7°C cooler than the norm, July’s mean minimum temperature of 23.6°C was 1.1°C warmer than average. This could be due to an elevated relative humidity. Levels of humidity averaged at 77.4%, a significant 7.2% over the climate norm. Elevated humidity prevents temperatures from shooting up during the day, but keeps them from cooling down at night. Despite the cooler maximum temperatures overall, real feels were generally uncomfortable, once again owing to the humidity levels. 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 Northwesterly wind also ensured that temperatures didn’t get too hot for too long. The hottest day last month was the 25^th, with the thermometers marking 37.7°C. Overall, values were typical of what one would expect from a Maltese summer.

July 2024 also lived up to its expectation of being a completely dry month. No rain made it to the Maltese Islands throughout. Some mist or fog patches were observed.

Warmer than Average in June 2025

 June was off to a comfortable start. This lasted only briefly, however, as the heat of summer quickly turned up on the 7^th. From then on, temperatures were above the climatic norm of 24.2°C on 23 days out of 24. The single cooler day was the 20^th, a day which brought a series of afternoon downpours to parts of the Maltese Islands, the heaviest of which struck Gozo. The 29^th, a Sunday, was the warmest day last month. The temperature peaked at 32.8°C on the day. For comparison, the mean maximum temperature for June is of 28.5°C. The pre-dawn hours of the 1^st day of the month were the coolest, with a minimum temperature of 14.6°C. June’s climatic mean minimum temperature of 19.8°C was exceeded by a total of 21 out of 30 nights.

Large swathes of western Europe were affected by a particularly intense heat wave, with temperature values regularly in the upper 40°Cs across Spain and Portugal. 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. This means that transfer of heat from the Sun to the sea surface is uninterrupted. The lack of wind and waves means that the sea isn’t mixing. This leads to a build-up of heat in the topmost layer of the sea. When the sea warms up too much, marine ecosystems are negatively impacted. Several marine species are not adapted to the warmer waters and therefore will suffer from poor health if not die. The lifecycle of numerous marine species goes haywire, especially where reproduction is concerned. Furthermore, marine ecosystems (especially those in shallower waters) experience a degree of degradation. The rates of oxygen dissolved in the water will also vary more widely. Finally, some alien species find it easier to spread in warmer waters, threatening the existence of more indigenous marine life. A very high sea surface temperature inhibits nighttime cooling in air temperatures. The high sea surface temperature will also contribute to increased rates of evaporation, which in turn, will lead to increased humidity. The more humid the air is, the warmer and clammier it will feel. Early and late mist or fog patches are also products of these increased levels of humidity.

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. Surprisingly, Gozo received the heaviest rainfall. Being the larger island, it is Malta that normally receives the most rainfall from these downpours. These clouds develop thanks to the vertical movement of columns of warm and humid air on sunny days and when the upper levels of the atmosphere are unstable due to the incursion of cold air from northern Europe. This is a process caused when the cold air in the upper levels of the atmosphere contrasts with the ground that has been well heated by the sun locally. This movement encourages the condensation of water vapor in this air and thus the formation of clouds. These showers, which affected only localized areas, lasted for a long while. Victoria, in Gozo, recorded up to 26.9 mm on that day. The national mean for the day, and also the month, was of 3.2 mm.

Warmer but Wetter than Average in May 2025

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. Despite the occasional unsettled spell, last month was warmer than average.

35.3 mm of rain was recorded at our weather station in May. The national mean was around this value too. This was almost four times the climate norm. There were five days with rain over the course of the month. One of them accounted for the vast majority of this rainfall: a staggering 29 mm of it. This was from a series of thundery downpours which affected all of the Maltese Islands on the 15^th. The 15^th also accounted for the month’s highest wind gust. That day was characterized by a near gale from the South Southeast. The remaining rainy days brought elevated thunderstorms with lots of loud thunder but modest rainfall accumulations. Copious amounts of fine desert sand were deposited by the lighter thunderstorms.

May’s mean temperature of 20.528 was just over half a degree warmer than the climate norm. While daytime temperatures were only marginally warmer than average, nights were warmer by just over a degree. The warmest day and night were those of the 28^th with a maximum and minimum of  28.6°C and 20.2°C respectively. The coldest night came earlier in the month, on the 3^rd April, with a minimum temperature of 12.2°C on a calm and clear night.

Levels of relative humidity were also noticeably elevated at 79.0%; owing to the wetter than average conditions.

April 2025 Ends on a Thundery Note

 

With a mean temperature of 16.5°C, temperatures in April were on par with the climate norm. Temperatures warmed up gradually as the month progressed, in typical springtime fashion.

With a national mean of 13.2 mm, rainfall was overall below the norm. In this case, simply looking at the national mean is extremely misleading. Whilst all localities in Malta featured rainfall values below the climate norm of 17.0 mm, all localities on the sister island of Gozo presented with rainfall totals well-above that. In fact, some localities registered double this! 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 29^th. 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.

Values for relative humidity, atmospheric pressure and wind showed marginal deviation from the climate norm; further confirming a typical April overall.

Warmer but Wetter in March 2025

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. In the transitional month of spring, a series of low pressure systems originate over northern Africa. Sciroccos occur in advance of a low pressure system moving eastward across the southern Mediterranean Sea or northern Africa. Air from high pressure over the Sahara Desert rushes in to fill this low pressure system. The rushing air manifests itself as a Scirocco. Their prevalence impacted the local weather in a number of ways.

At 15.8°C, mean temperatures were 1.8°C warmer than the norm. The difference from the mean for both maximum and minimum temperatures stood at the same value. The month’s warmest temperature was measured in the evening of the 23^rd. Measured at 26.8°C, this was during one of several heat bursts. 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. The behaviour of air pressure also revealed tell-tale signs of a heat burst. It climbed by 3hPa, from 1009.5hPa to 1012.5hPa, over the same time. This lasted for some time and occurred several times. That evening also accounted for the month’s highest wind gust of 59.5km/h.

Relative humidity stood at an uncomfortable level of 81.4% overall. Numerous days recorded means of above 90%.

March 2025 was the third month with more rainfall than average since September 1^st and the second consecutive after February 2025. A total of 78.0 mm were 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. The bulk came from two of these; one during the first week of the month and another towards its end.

February 2025 – Rainfall Totals Bounce Back

The 66.0 mm of precipitation measured at our weather station in Gozo was marginally above the climate norm for 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 due to the fact that most rain-bearing systems came to our islands with easterly currents. These affect Malta far more than Gozo. A case in point was the 20^th. Maltese localities experienced continuous heavy rain in the morning. Gozo only received a few showers. More than half of all days last month; 15 in total, registered rainfall. The highlight was a hailstorm with large hailstones over the southern half of Malta, particularly Birżebbuġa and Għaxaq, on Valentine’s Day. February was the second wetter than average since last September 1^st, along with February.

Temperatures were significantly warmer than average, particularly during the day. The mean maximum temperature of 17.1°C exceeded the norm by 1.5°C. Overall temperatures were  0.8°C above typical values for the time of year. 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). This state of affairs is being maintained for now. When that happens, low pressure systems from over the Sahara Desert can reach us more freely, together with more frequent southeasterly winds and warmer than average temperatures. The difference from the climate norm with minimum temperatures was of only 0.3°C. This was thanks to a number of chilly nights brought about by numerous calm and clear nights, the coldest of which was the dawn of the 23^rd when the mercury dipped to 5.8°C!

Winds were weaker than normal, with less gales than normal. Atmospheric pressure averaged 1022hPa. This is stronger than normal.

Springtime Temperatures in January 2025

Almost half of all days (15) last January were characterized by at least one shower over one area or another of the Maltese Islands. Rain was measured at our weather station on eight of these. Thunder was heard on three of these while hail was recorded once. Despite these days of rain, January’s total precipitation of 63.0 mm was less than the value for a typical January. The total rainfall at our weather station was at 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. This comprised a mean maximum temperature of 17.5°C (1.9°C warmer than average) and a mean minimum temperature of 11.7°C (1.6°C warmer than average). These temperatures are more typical of Easter time rather than the peak of winter! The maximum temperature of 19.5°C on January 26^th was far from breaking absolute temperature records, however. A calm and clear night on the 16^th accounted for the month’s coldest minimum temperature of 5.6°C.
