The year, day by day
Pocatello Rgnl works both ends of the calendar. Normal highs climb to 91°F by July 25 and hold at or above 90°F on 25 dates, then normal lows drop to freezing or below on 176 dates, bottoming at 16°F around January 1.
When the heat sits
Normal highs reach 90°F from July 16 through August 9, covering 25 dates. The broader mild season, normal highs of 70°F or more, runs May 20 to September 30.
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 11, then returns to freezing around October 19, covering 176 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 1, when 35% of years recorded at least a hundredth of an inch. The driest is July 10 at 13%. Summed across the calendar, that is about 93 wet dates a year.
The widest day
July 29 carries the biggest normal gap between afternoon and dawn, 38°F between the normal high and the normal low.

Where Pocatello Rgnl Stands Nationally
Aridity defines the water calendar: about 12 inches in a normal year lands this among the driest tenth of ranked stations.
Day-to-night contrast is extreme by national standards — the widest normal daily swing reaches about 38°F, sharper than nine in ten ranked stations see.

Pocatello Rgnl spreads its precipitation across the year
Neither half of the year dominates here: June through August take 17% of the annual total and December through February 27%, with neither reaching the 35% that would mark a distinct wet season. Pocatello Rgnl has no dry season to plan around, though it does carry a wide 45.2°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: May averages 1.4" and July 0.5". The three wettest months together take 32% 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.
Pocatello Rgnl is dry, and what does fall arrives gently
Only about 93 days a year record measurable precipitation here, 25% of the calendar, and they carry 11.8" between them. At roughly 0.13 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 December at about 11 wet days; the driest is July at about 4.
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 Pocatello Rgnl
Pocatello Rgnl averages 38.5 inches of snowfall a year, with December the snowiest month on the normals, spread across roughly 36 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: 38.5 inches of depth.
- Days recording measurable snow: about 36 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 33% of the year's precipitation.

Snow and freeze rhythm
When cold and snow define Pocatello Rgnl
heating led · dry · mid swing
Pocatello Rgnl's energy balance leans toward cold weather: 6,954 annual heating degree days against 431 for cooling. Its 45.2°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 118 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.

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