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.

1940Each stripe is one year’s mean temperature against the 47-year average. Warmest: 2024. Coolest: 1948.2025

Place identity: GeoNames 9957340
NOAA station: ASN00040211 · ARCHERFIELD AIRPORT
Station distance: 7.1 km from the place centre
Climate period: 1991–2020
Minimum month coverage: 26 usable years
