The year, day by day
Summer here tops out rather than builds: the warmest normal high is 89°F around July 26, short of 90°F on every date, while 190 dates carry a normal low at or below freezing, the coldest 10°F near January 3.
The freezing stretch
The normal low stays at or below 32°F into April 18, then returns to freezing around October 12, covering 190 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 June 2, when 33% of years recorded at least a hundredth of an inch. The driest is September 2 at 16%. Summed across the calendar, that is about 78 wet dates a year.
The widest day
August 7 carries the biggest normal gap between afternoon and dawn, 37°F between the normal high and the normal low.

Where Salmon-ksra Stands Nationally
Aridity defines the water calendar: about 10 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 37°F, sharper than nine in ten ranked stations see.

Salmon-ksra spreads its precipitation across the year
Neither half of the year dominates here: June through August take 32% of the annual total and December through February 18%, with neither reaching the 35% that would mark a distinct wet season. Salmon-ksra has no dry season to plan around, though it does carry a wide 49.4°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: June averages 1.6" and February 0.4". The three wettest months together take 39% 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.
Salmon-ksra is dry, and what does fall arrives gently
Only about 78 days a year record measurable precipitation here, 21% of the calendar, and they carry 9.5" between them. At roughly 0.12 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 June at about 9 wet days; the driest is February 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.
Winter brings real snow to Salmon-ksra
Salmon-ksra averages 22.0 inches of snowfall a year, with January the snowiest month on the normals, spread across roughly 15 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: 22.0 inches of depth.
- Days recording measurable snow: about 15 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 23% 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 Salmon-ksra
heating led · dry · mid swing
Salmon-ksra's energy balance leans toward cold weather: 7,765 annual heating degree days against 293 for cooling. Its 49.4°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 130 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 Salmon-ksra; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
