The year, day by day
Summer here tops out rather than builds: the warmest normal high is 86°F around July 26, short of 90°F on every date, while 220 dates carry a normal low at or below freezing, the coldest 21°F near December 19.
The freezing stretch
The normal low stays at or below 32°F into May 12, then returns to freezing around October 6, covering 220 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 November 20, when 40% of years recorded at least a hundredth of an inch. The driest is August 10 at 10%. Summed across the calendar, that is about 97 wet dates a year.
The widest day
July 25 carries the biggest normal gap between afternoon and dawn, 43°F between the normal high and the normal low.

Where Grizzly Stands Nationally
Winters bite deep and often: the normal nightly low dips to freezing or below on around 220 nights a year, placing this among the most frost-prone tenth of ranked stations.
Day-to-night contrast is extreme by national standards — the widest normal daily swing reaches about 43°F, sharper than nine in ten ranked stations see.

Grizzly spreads its precipitation across the year
Neither half of the year dominates here: June through August take 15% of the annual total and December through February 31%, with neither reaching the 35% that would mark a distinct wet season. Grizzly has no dry season to plan around, though it does carry a 31.3°F seasonal spread.
The gap between the wettest and driest month still matters: December averages 1.7" and August 0.4". The three wettest months together take 35% 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.
Grizzly is dry, and what does fall arrives gently
Only about 97 days a year record measurable precipitation here, 27% of the calendar, and they carry 13.4" between them. At roughly 0.14 inches on an average wet day, this is not the damp drizzle of a marine climate; it is an arid record in which precipitation is both uncommon and light when it appears.
The wettest month by count is November at about 12 wet days; the driest is August at about 3.
A low per-event average in a dry record is a statement about typical days only. Arid regions can still take a large share of a year's total from a single convective storm, which a normal cannot show.
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year, not the extremes within it.
Winter brings real snow to Grizzly
Grizzly averages 21.2 inches of snowfall a year, with December the snowiest month on the normals, spread across roughly 10 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: 21.2 inches of depth.
- Days recording measurable snow: about 10 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 16% 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.

Grizzly's energy balance leans toward cold weather: 7,211 annual heating degree days against 99 for cooling. Its 31.3°F seasonal range still makes the monthly rows more useful than the annual average alone.
A frost-free growing-season length is not available for Grizzly. That missing field is kept separate from the observed temperature and precipitation record rather than filled from a regional estimate.
-
1. Grizzly 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. Grizzly typical freeze period
January through December
The station reports average freezing days from January through December.
-
3. Grizzly snow peak
December
Grizzly averages 21.2 inches of snow a year, with December the snowiest month on the normals.

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 Grizzly; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
