The year, day by day
Summer here tops out rather than builds: the warmest normal high is 89°F around July 16, short of 90°F on every date, while 169 dates carry a normal low at or below freezing, the coldest 10°F near January 5.
The freezing stretch
The normal low stays at or below 32°F into April 9, then returns to freezing around October 24, covering 169 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 August 13, when 26% of years recorded at least a hundredth of an inch. The driest is November 25 at 14%. Summed across the calendar, that is about 67 wet dates a year.
The widest day
June 22 carries the biggest normal gap between afternoon and dawn, 34°F between the normal high and the normal low.

Where Duchesne Stands Nationally
Aridity defines the water calendar: about 10 inches in a normal year lands this among the driest tenth of ranked stations.
Daily temperature swings run wider than most of the country, peaking near 34°F between the normal high and low.
Duchesne earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Duchesne spreads its precipitation across the year
Neither half of the year dominates here: June through August take 30% of the annual total and December through February 17%, with neither reaching the 35% that would mark a distinct wet season. Duchesne has no dry season to plan around, though it does carry a wide 50.5°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: August averages 1.4" and November 0.5". The three wettest months together take 38% 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.
Duchesne is dry, and what does fall arrives gently
Only about 67 days a year record measurable precipitation here, 18% of the calendar, and they carry 9.4" 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 August at about 8 wet days; the driest is November 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 Duchesne
Duchesne averages 29.1 inches of snowfall a year, with December the snowiest month on the normals, spread across roughly 18 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: 29.1 inches of depth.
- Days recording measurable snow: about 18 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 31% 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 Duchesne
heating led · dry · mid swing
Duchesne's energy balance leans toward cold weather: 6,663 annual heating degree days against 533 for cooling. Its 50.5°F seasonal range still makes the monthly rows more useful than the annual average alone.
Duchesne's frost-free season lasts about 152 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
