The year, day by day
Summer here tops out rather than builds: the warmest normal high is 84°F around July 9, short of 90°F on every date, while 106 dates carry a normal low at or below freezing, the coldest 23°F near January 23.
The freezing stretch
The normal low stays at or below 32°F into March 14, then returns to freezing around November 30, covering 106 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 January 13, when 48% of years recorded at least a hundredth of an inch. The driest is September 4 at 31%. Summed across the calendar, that is about 148 wet dates a year.
The widest day
April 20 carries the biggest normal gap between afternoon and dawn, 24°F between the normal high and the normal low.

Fairmont spreads its precipitation across the year
Neither half of the year dominates here: June through August take 28% of the annual total and December through February 23%, with neither reaching the 35% that would mark a distinct wet season. Fairmont has no dry season to plan around, though it does carry a 41.8°F seasonal spread.
The gap between the wettest and driest month still matters: May averages 5.1" and November 3.1". The three wettest months together take 31% of the year, against the 25% a perfectly flat distribution would give them.
Shares are computed from this station's own 1991-2020 monthly precipitation normals. "Spread across the year" means neither the June-August nor the December-February share reaches 35%; it describes an average year, not the variability of any single one.
How Fairmont's precipitation splits across the calendar
About 148 days a year record measurable precipitation here, carrying 47.8" 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 · wet · mid swing
Fairmont's energy balance leans toward cold weather: 5,017 annual heating degree days against 897 for cooling. Its 41.8°F seasonal range still makes the monthly rows more useful than the annual average alone.
Fairmont's frost-free season lasts about 193 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
July and January mark the typical warm and cold ends of the calendar in Fairmont's middle-range seasonal profile. The measured spread is 41.8°F. The annual average is 54°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Alongside its heating load, Fairmont carries 47.8 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 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.
