The year, day by day
Summer here tops out rather than builds: the warmest normal high is 87°F around July 14, short of 90°F on every date, while 170 dates carry a normal low at or below freezing, the coldest 16°F near December 19.
The freezing stretch
The normal low stays at or below 32°F into April 13, then returns to freezing around October 27, covering 170 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 August 1, when 32% of years recorded at least a hundredth of an inch. The driest is January 9 at 14%. Summed across the calendar, that is about 81 wet dates a year.
The widest day
September 22 carries the biggest normal gap between afternoon and dawn, 30°F between the normal high and the normal low.

Kassler spreads its precipitation across the year
Neither half of the year dominates here: June through August take 30% of the annual total and December through February 11%, with neither reaching the 35% that would mark a distinct wet season. Kassler has no dry season to plan around, though it does carry a 41.6°F seasonal spread.
The gap between the wettest and driest month still matters: May averages 2.5" and January 0.6". The three wettest months together take 38% 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 Kassler's precipitation splits across the calendar
About 80 days a year record measurable precipitation here, carrying 18.2" 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 Kassler
Kassler averages 62.2 inches of snowfall a year, with December the snowiest month on the normals, spread across roughly 23 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: 62.2 inches of depth.
- Days recording measurable snow: about 23 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 34% of the year's precipitation.
NOAA 1991-2020 normals. The ten-to-one ratio is a convention, not a measurement: real ratios vary with temperature, so treat the share as an order of magnitude rather than an exact split.

Snow and freeze rhythm
When cold and snow define Kassler
heating led · dry · mid swing
Kassler's energy balance leans toward cold weather: 6,013 annual heating degree days against 645 for cooling. Its 41.6°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 148 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.
-
1. Kassler coldest normal
December
The monthly mean of 31°F (0°C) sits near freezing, so cold nights and above-freezing afternoons share the same month.
-
2. Kassler typical freeze period
January through December
The station reports average freezing days from January through December.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Kassler's primary station: KASSLER (USC00054452). For informational purposes only.
Place identity: U.S. Census Bureau 2024 Gazetteer places. The conservative exact name-and-state crosswalk finds no Census place match, so PlainClimate treats this as a station-mapped location and does not claim it is a municipality. No exact Gazetteer row for Kassler; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
On this page every temperature, precipitation, and derived score for Kassler comes from its primary NOAA station record.
