Shoshoni's normals sit in a dry climate class: BWk
Annual precipitation falls well below the aridity threshold for this temperature regime, so the normals classify as cold desert (BWk). Class BWk is the Peel et al. (2007) label for this station's monthly mean temperature and precipitation normals: dry (arid or semi-arid), specifically cold desert.

The year, day by day
Shoshoni works both ends of the calendar. Normal highs climb to 91°F by July 22 and hold at or above 90°F on 30 dates, then normal lows drop to freezing or below on 179 dates, bottoming at -1°F around January 4.
When the heat sits
Normal highs reach 90°F from July 11 through August 9, covering 30 dates. The broader mild season, normal highs of 70°F or more, runs May 16 to September 28.
This counts calendar dates whose 1991–2020 normal high reaches 90°F. It is a smaller number than the 90°F+ day counts in the monthly table above, which measure how often the threshold was actually crossed in a typical year. A date can average 88°F and still exceed 90°F in half of all years.
The freezing stretch
The normal low stays at or below 32°F into April 12, then returns to freezing around October 17, covering 179 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 19, when 23% of years recorded at least a hundredth of an inch. The driest is December 9 at 5%. Summed across the calendar, that is about 39 wet dates a year.
The widest day
August 15 carries the biggest normal gap between afternoon and dawn, 34°F between the normal high and the normal low.

Where Shoshoni Stands Nationally
Aridity defines the water calendar: about 8 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 179 nights a year, more than most ranked stations.
Shoshoni earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Shoshoni 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 10%, with neither reaching the 35% that would mark a distinct wet season. Shoshoni has no dry season to plan around, though it does carry a wide 59.4°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: May averages 1.8" and December 0.2". 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 Shoshoni's precipitation splits across the calendar
About 38 days a year record measurable precipitation here, carrying 8.0" between them, or roughly 0.21 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 Shoshoni
Shoshoni averages 17.5 inches of snowfall a year, with February 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: 17.5 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 22% of the year's precipitation.

Snow and freeze rhythm
When cold and snow define Shoshoni
heating led · dry · high swing
Winter and seasonal range jointly define this record. Shoshoni logs 7,670 heating degree days, more than twice its 641 cooling total, while the typical coldest-to-warmest-month gap reaches 59.4°F. The annual mean therefore compresses two materially different seasons.
Only about 149 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.
