The year, day by day
Summer here tops out rather than builds: the warmest normal high is 80°F around July 29, short of 90°F on every date, while 216 dates carry a normal low at or below freezing, the coldest 7°F near January 1.
The freezing stretch
The normal low stays at or below 32°F into May 5, then returns to freezing around October 3, covering 216 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 5, when 35% of years recorded at least a hundredth of an inch. The driest is July 12 at 17%. Summed across the calendar, that is about 97 wet dates a year.
The widest day
August 22 carries the biggest normal gap between afternoon and dawn, 33°F between the normal high and the normal low.

Where Tetonia Exp Stn Stands Nationally
Winters bite deep and often: the normal nightly low dips to freezing or below on around 216 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 33°F between the normal high and low.
Tetonia Exp Stn earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Tetonia Exp Stn spreads its precipitation across the year
Neither half of the year dominates here: June through August take 20% of the annual total and December through February 28%, with neither reaching the 35% that would mark a distinct wet season. Tetonia Exp Stn has no dry season to plan around, though it does carry a wide 45.1°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: May averages 2.3" and July 0.9". The three wettest months together take 34% 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.
Tetonia Exp Stn is dry, and what does fall arrives gently
Only about 96 days a year record measurable precipitation here, 26% of the calendar, and they carry 19.0" between them. At roughly 0.20 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 January at about 11 wet days; the driest is July at about 5.
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.

Data-derived climate profile
How Tetonia Exp Stn's climate pattern fits together
heating led · dry · mid swing
Tetonia Exp Stn's energy balance leans toward cold weather: 9,383 annual heating degree days against 66 for cooling. Its 45.1°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 84 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.
July and January mark the typical warm and cold ends of the calendar in Tetonia Exp Stn's middle-range seasonal profile. The measured spread is 45.1°F. The annual average is 39°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Tetonia Exp Stn's cold-season load does not imply a wet climate. Annual precipitation is 19.0 inches, which places the station in PlainClimate's dry range. Snowfall is not added to the interpretation because its annual value is missing. The snowfall and rainfall fields should be read separately rather than inferred from temperature.
These labels group NOAA 1991-2020 normals from Tetonia Exp Stn'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 Tetonia Exp Stn, not an official NOAA class or a year-ahead forecast.

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 Tetonia Exp Stn; 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 Tetonia Exp Stn comes from its primary NOAA station record.
