Relief in August 2023
After a record-breaking 10-day heat wave in July, August 2023 proved a breath of fresh air for the Maltese Islands. With a mean temperature of 26.4°C at our weather station in Għarb, last month was 1.2°C cooler than the climate norm. The mean maximum temperature of 30.0°C was a staggering 1.8°C below the norm. The mean minimum temperature of 22.8°C, on the other hand, was 0.5°C below the average. The maximum temperature last month peaked at 32.9°C on the 23rd. Elsewhere in the Maltese Islands, the hottest days over the course of last August registered a maximum temperature of ‘only’ 35°C, a far cry from what these values normally stand at in a normal August. Maximum temperatures failed to exceed the 30°C mark on half of all days last month. There were also two nights where the minimum temperature dropped to below 20°C. Not all was perfect, however. Values of relative humidity were higher than the norm, particularly after the thunderstorm on the 21st. This made the air feel rather clammy and uncomfortable at times.
August rain is not unheard of across the Maltese Islands, particularly as the month nears its end. August 2023 was characterised by two separate rainfall events. There were two separate isolated thunderstorms on the 21st. One struck Gozo in the predawn hours. Another formed over central Malta in the daylight hours. 9.1 mm of rain were measured by our rain gauge in Għarb on the day. Whilst this was to be the only day with rain across Gozo, another stronger thunderstorm struck Malta on the month’s final day. August went out with a bang for some localities, particularly Mosta, where over 40 mm of rain were measured.
There were two outbreaks of strong wind, one towards the beginning and another towards the end. The highest wind gust was recorded on the 5th, and measured at 49.9 km/h (almost Force 7) from a Northwesterly direction.
