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 23rd. 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 1st 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.
