Significantly Hotter than Average in August 2021

August 2021 was the hottest month of the year. The mean temperature exceeded the norm by a staggering 1.6°C. Maximum temperatures were 1°C hotter than average. Nighttime lows were 2.2°C warmer than average. This wider anomaly may be attributed to the warmer than average sea surrounding the Maltese Islands. A very warm sea inhibits nighttime cooling. The hottest day was the 1st, with a maximum temperature of 37.3°C. Temperatures exceeded the 40°C mark on the day, in more central spots on Malta. A total of eighteen days registered a maximum temperature greater than the climate mean. The coolest temperature of 21.1°C was measured at dawn on the 20th. This was one of only a handful of nights with a minimum temperature dipping to below average.

A heavy rain shower was observed over a handful of localities in central Malta on 22nd August. Most places remained dry on the day, however. This extended the dry run for the driest of localities to 150 days.
