measured normals and 10 years of recorded weatherLondon swings 20°C across the year, from 22°C highs in June to 2°C lows in January, and September is usually the wettest month in a year that brings about 836 mm of precipitation. Over 10 years of recorded weather it averages 21 days a year at 25°C or above, 4 of them at 30°C or above, 30 frost nights, and rain on 131 days.
Day counts are from the ERA5 reanalysis for London’s grid square, 2016 to 2025, counted the same way for every city so the numbers compare. A reanalysis square is an area, not a weather station, so it is good for counting days and not for a single day’s record.
