The best month has moved. On the 1961–1990 numbers the strongest month here was June (scoring 80); on 2011–2025 it is August (82). Both are scored the same way, from the same station — only the climate underneath changed.

A warm and dry day reaches 20°C with under 1 mm of rain; a wet day gets 1 mm or more; a washout gets 10 mm or more. The week column is the share of seven-day stretches in that month, across the station’s whole daily record, that contained three or more wet days — the odds a week-long trip is rained on repeatedly, counted rather than modelled. The last column is the 10th to 90th percentile of that month’s daytime average across individual years: a narrow band means the average is what you will get, a wide one means the average is a midpoint between years that felt quite different.

1922Each stripe is one year’s mean temperature against the 98-year average. Warmest: 1931. Coolest: 1979.2024
