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.

1967Each stripe is one year’s mean temperature against the 21-year average. Warmest: 1992. Coolest: 1967.2025

The evidence behind this page

Nearby, measured,
and named.

Place identity: GeoNames 5335935
NOAA station: USW00003154 · CAMP PENDLETON MCAS
Station distance: 1.4 km from the place centre
Climate period: 1991–2020
Minimum month coverage: 17 usable years
Daylight: Calculated from latitude 33.29°, mid-month, sunrise to sunset including refraction. Not a station measurement.
Sea temperature: NOAA OISST v2.1 1991–2020 monthly climatology, nearest open water 19 km from the place centre. A sheltered bay can run warmer than the open sea it is measured from.
Important limit: Historical climate is not a forecast. Nearby stations can miss mountains, coasts, and local microclimates.

These places read the same station, so their numbers are identical — distance from CAMP PENDLETON MCAS is what differs
