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 26th was far from breaking absolute temperature records, however. A calm and clear night on the 16th accounted for the month’s coldest minimum temperature of 5.6°C.
