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.
