The year, day by day
Summer here tops out rather than builds: the warmest normal high is 87°F around July 22, short of 90°F on every date, while 189 dates carry a normal low at or below freezing, the coldest 8°F near December 24.
The freezing stretch
The normal low stays at or below 32°F into April 21, then returns to freezing around October 16, covering 189 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 May 11, when 18% of years recorded at least a hundredth of an inch. The driest is January 24 at 6%. Summed across the calendar, that is about 37 wet dates a year.
The widest day
July 12 carries the biggest normal gap between afternoon and dawn, 31°F between the normal high and the normal low.

Where Pavillion Stands Nationally
Aridity defines the water calendar: about 9 inches in a normal year lands this among the driest tenth of ranked stations.
Freezing is routine here by normals standards — the normal low reaches 32°F or colder on about 189 nights a year, more than most ranked stations.
Pavillion earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Pavillion 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 9%, with neither reaching the 35% that would mark a distinct wet season. Pavillion has no dry season to plan around, though it does carry a wide 49.3°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: May averages 2.1" and January 0.3". The three wettest months together take 49% 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 Pavillion's precipitation splits across the calendar
About 37 days a year record measurable precipitation here, carrying 8.8" between them, or roughly 0.24 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 Pavillion
Pavillion averages 28.4 inches of snowfall a year, with April the snowiest month on the normals, spread across roughly 11 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: 28.4 inches of depth.
- Days recording measurable snow: about 11 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 32% of the year's precipitation.

Snow and freeze rhythm
When cold and snow define Pavillion
heating led · dry · mid swing
Pavillion's energy balance leans toward cold weather: 7,647 annual heating degree days against 374 for cooling. Its 49.3°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 139 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.
