The year, day by day
Summer here tops out rather than builds: the warmest normal high is 84°F around July 6, short of 90°F on every date, while 160 dates carry a normal low at or below freezing, the coldest 6°F near January 21.
The freezing stretch
The normal low stays at or below 32°F into April 9, then returns to freezing around November 2, covering 160 dates in all.
Derived from the normal daily minimum. This is a different measure from the 50%-probability frost dates shown elsewhere on this page, which come from NOAA’s frost product.
Where the wet dates fall
The likeliest wet date is June 2, when 41% of years recorded at least a hundredth of an inch. The driest is November 17 at 20%. Summed across the calendar, that is about 103 wet dates a year.
The widest day
September 17 carries the biggest normal gap between afternoon and dawn, 23°F between the normal high and the normal low.

Where Fairmont Stands Nationally
Days and nights track unusually close together; the widest normal swing, about 23°F, is narrower than most stations record.

Fairmont runs a summer-peaked wet season
38% of Fairmont's yearly precipitation falls in June, July and August alone, against the 25% an evenly spread year would give those three months. The wettest month is June at 5.0", on a wide 58.2°F gap between its warmest and coldest month. Warm-season convection and, across the Southwest, the North American monsoon produce this shape: rain arrives in short heavy bursts during the hottest part of the year rather than as long cool-season soaking.
- Wettest three months: June, May, July, taking 40% of the annual total between them.
- Driest month: January at 0.8".
- Winter share: 10% falls in December, January and February.
Shares are computed from this station's own 1991-2020 monthly precipitation normals. A summer-peaked label means the June-August share reaches 35%; it describes timing across an average year, not any single season, and says nothing about how heavy an individual storm can be.
How Fairmont's precipitation splits across the calendar
About 103 days a year record measurable precipitation here, carrying 33.5" between them, or roughly 0.32 inches on a typical wet day. That sits in the middle band: neither the many-light-days pattern of the Pacific Northwest and the Great Lakes, nor the few-heavy-events pattern of the Gulf and the desert Southwest.
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year and say nothing about the heaviest single storm on record.

Data-derived climate profile
How Fairmont's climate pattern fits together
heating led · moderate · high swing
Winter and seasonal range jointly define this record. Fairmont logs 7,608 heating degree days, more than twice its 773 cooling total, while the typical coldest-to-warmest-month gap reaches 58.2°F. The annual mean therefore compresses two materially different seasons.
Fairmont's frost-free season lasts about 172 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
Fairmont's calendar has a pronounced split: July and January mark the typical warm and cold ends of the calendar, with 58.2°F between them. The annual average is 46°F. That average is context, while the monthly highs, lows, and precipitation totals describe the lived parts of the year.
Fairmont's 33.5 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Snowfall is not added to the interpretation because its annual value is missing. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
These labels group NOAA 1991-2020 normals from Fairmont'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 Fairmont, not an official NOAA class or a year-ahead forecast.
