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.

1930Each stripe is one year’s mean temperature against the 77-year average. Warmest: 2010. Coolest: 1939.2023

Place identity: GeoNames 4963947
NOAA station: CA008100300 · AROOSTOOK

Minimum month coverage: 23 usable years
Daylight: Calculated from latitude 46.70°, mid-month, sunrise to sunset including refraction. Not a station measurement.
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 AROOSTOOK is what differs
