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.

1906Each stripe is one year’s mean temperature against the 116-year average. Warmest: 1998. Coolest: 1917.2025

Place identity: GeoNames 5274867
NOAA station: USC00478267 · STURGEON BAY EXP FARM
Station distance: 6 km from the place centre
Climate period: 1991–2020
Minimum month coverage: 30 usable years
Daylight: Calculated from latitude 44.83°, mid-month, sunrise to sunset including refraction. Not a station measurement.
