The year, day by day
The calendar barely moves in Mapleton: no date carries a normal high of 90°F or a normal low at freezing. The year runs between 40°F near December 16 and 81°F near July 24.
No freezing date
Not one calendar date in the 1991–2020 record carries a normal low at or below 32°F. The coldest normal low of the year is 40°F around December 16.
The widest day
September 4 carries the biggest normal gap between afternoon and dawn, 27°F between the normal high and the normal low.

Where Mapleton Stands Nationally
This is one of the wettest normals climates ranked: about 84 inches of precipitation in a normal year, a total fewer than one station in ten surpasses.
Mapleton earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.
Monthly Precipitation
Average monthly rainfall
Mapleton's wet season runs through the cold months
December, January and February carry 46% of the year's precipitation here, while June through August contribute 4%. That is the cool-season-dominant pattern of the West Coast and the higher inland West, where storm tracks swing south in winter and summer turns dry; the thermometer meanwhile shows an unusually narrow 22°F seasonal spread.
- Wettest month
- December, 15.3"
- Driest month
- July, 0.5"
- Wettest three months
- December, January, November (49% of the year)
Shares are computed from this station's own 1991-2020 monthly precipitation normals. A cool-season label means the December-February share reaches 35%. Where snow falls, the monthly figures above report liquid-equivalent precipitation, so a wet winter month is not necessarily a rainy one.

Data-derived climate profile
How Mapleton's climate pattern fits together
heating led · wet · low swing
Heating is the larger measured load in Mapleton, at 3,673 degree days versus 261 for cooling. Unlike a strongly continental record, however, its 22.0°F month-to-month range is compact; persistent cool-season demand matters more than a dramatic summer-to-winter reversal.
The frost-free window extends for about 297 days. That is a long calendar measure, but it is not a forecast and does not combine heat, rainfall, soil, or local elevation into a planting recommendation.
Mapleton's 22.0°F seasonal spread is compact even though precipitation is abundant. August and December mark the typical warm and cold ends of the calendar. The annual average is 56°F. Temperature is relatively steady; the monthly rows show how rain and snow observations vary across the calendar.
Alongside its heating load, Mapleton carries 84.0 inches of precipitation in a normal year, inside PlainClimate's wet range. Snowfall is not added to the interpretation because its annual value is missing. That distinction matters because a wet annual total can arrive as rain, snow, or a mixture at different times.
These labels group NOAA 1991-2020 normals from Mapleton's primary station, so the winter figures are a thirty-year average and not a floor: a single hard season can run well below them. Treat each band as a descriptive range for Mapleton, not an official NOAA class or a year-ahead forecast.
