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.

1881Each stripe is one year’s mean temperature against the 32-year average. Warmest: 2012. Coolest: 1883.2023

and named.

Place identity: GeoNames 5918097
NOAA station: CA007021954 · DANVILLE
Station distance: 0.5 km from the place centre
