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.

1939Each stripe is one year’s mean temperature against the 51-year average. Warmest: 1984. Coolest: 1962.2004

Place identity: GeoNames 5393212
NOAA station: USC00047953 · SANTA MONICA PIER
Station distance: 1.5 km from the place centre
Climate period: 1991–2020
Minimum month coverage: 15 usable years
Daylight: Calculated from latitude 34.02°, mid-month, sunrise to sunset including refraction. Not a station measurement.
