A very wet month with many cool days. There was more thunder this month than over the whole of summer 2024, and almost as much rain (summer 2024 rain: 163.8 mm). Nights were warmer than average, which meant the overall mean temperature was only just below average. The rainfall figure is even more unusual as the middle third of the month (9th-21st) only experienced 9.9 mm.
Anomalies (in brackets) refer to the estimated 1991-2020 averages.
