measured normals and 10 years of recorded weatherLeiston swings 19°C across the year, from 21°C highs in August to 2°C lows in January, and October is usually the wettest month in a year that brings about 632 mm of precipitation. Over 10 years of recorded weather it averages 7 days a year at 25°C or above, 18 frost nights, and rain on 131 days.
Day counts are from the ERA5 reanalysis for Leiston’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.

Source: NASA POWER daily data from the MERRA-2 reanalysis, 1995-2024. Each value describes a grid square of about 50 km around Leiston, not a weather station, and a square that takes in sea or a large lake runs milder than the city itself. That is why this section shows change against the square's own 30-year average rather than counts you could compare with a local station. Rain and snow are left out because their long-term record in this dataset is not consistent over time. "Within the normal year-to-year swing" means the change is smaller than the usual differences between single years.
