The year, day by day
Summer here tops out rather than builds: the warmest normal high is 81°F around July 29, short of 90°F on every date, while 217 dates carry a normal low at or below freezing, the coldest 13°F near February 11.
The freezing stretch
The normal low stays at or below 32°F into May 10, then returns to freezing around October 7, covering 217 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 1, when 40% of years recorded at least a hundredth of an inch. The driest is January 27 at 17%. Summed across the calendar, that is about 85 wet dates a year.
The widest day
August 8 carries the biggest normal gap between afternoon and dawn, 35°F between the normal high and the normal low.

Where Wilsall Stands Nationally
Winters bite deep and often: the normal nightly low dips to freezing or below on around 217 nights a year, placing this among the most frost-prone tenth of ranked stations.
Daily temperature swings run wider than most of the country, peaking near 35°F between the normal high and low.
Wilsall earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Wilsall spreads its precipitation across the year
Neither half of the year dominates here: June through August take 34% of the annual total and December through February 12%, with neither reaching the 35% that would mark a distinct wet season. Wilsall has no dry season to plan around, though it does carry a 39.2°F seasonal spread.
The gap between the wettest and driest month still matters: June averages 3.5" and February 0.7". The three wettest months together take 45% 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 Wilsall's precipitation splits across the calendar
About 85 days a year record measurable precipitation here, carrying 19.3" between them, or roughly 0.23 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.
Winter brings real snow to Wilsall
Wilsall averages 81.7 inches of snowfall a year, with March the snowiest month on the normals, spread across roughly 28 days that record measurable snow. That is depth accumulating on the ground, which is why it can exceed the annual precipitation figure: precipitation counts the liquid the snow melts down to, and fresh snow is mostly air.
- Annual snowfall: 81.7 inches of depth.
- Days recording measurable snow: about 28 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 42% of the year's precipitation.

Snow and freeze rhythm
When cold and snow define Wilsall
heating led · dry · mid swing
Wilsall's energy balance leans toward cold weather: 8,878 annual heating degree days against 59 for cooling. Its 39.2°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 91 days are frost-free in a normal year. That short interval is consistent with the cold-season signal, but the measure does not predict the exact first or last freeze in any one year.

Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Wilsall's primary station: WILSALL 8 ENE (USC00249023). 2 NOAA stations are mapped to the Wilsall area; the primary station's record is used for consistency. For informational purposes only.
Place identity: U.S. Census Bureau 2024 Gazetteer places. The 2024 Census Gazetteer identifies the exact name-and-state match as a census-designated place (GEOID 3080875), not an incorporated municipality. Match rule for Wilsall: exact normalized name + state only, no fuzzy expansion, so nearby differently spelled facilities stay unmatched.
