The year, day by day
Summer here tops out rather than builds: the warmest normal high is 82°F around July 20, short of 90°F on every date, while 205 dates carry a normal low at or below freezing, the coldest 11°F near January 1.
The freezing stretch
The normal low stays at or below 32°F into May 4, then returns to freezing around October 13, covering 205 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 3, when 40% of years recorded at least a hundredth of an inch. The driest is January 14 at 21%. Summed across the calendar, that is about 105 wet dates a year.
The widest day
August 25 carries the biggest normal gap between afternoon and dawn, 30°F between the normal high and the normal low.

Where Laramie Stands Nationally
Winters bite deep and often: the normal nightly low dips to freezing or below on around 205 nights a year, placing this among the most frost-prone tenth of ranked stations.
A drier-than-most normal water year — around 13 inches, below what four out of five ranked stations collect.
Laramie earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Laramie 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 10%, with neither reaching the 35% that would mark a distinct wet season. Laramie has no dry season to plan around, though it does carry a 43.8°F seasonal spread.
The gap between the wettest and driest month still matters: May averages 2.0" and January 0.4". The three wettest months together take 42% 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.
Laramie is dry, and what does fall arrives gently
Only about 105 days a year record measurable precipitation here, 29% of the calendar, and they carry 13.1" 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 May at about 13 wet days; the driest is January at about 6.
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 Laramie
Laramie averages 64.1 inches of snowfall a year, with April the snowiest month on the normals, spread across roughly 51 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: 64.1 inches of depth.
- Days recording measurable snow: about 51 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 49% 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 Laramie
heating led · dry · mid swing
Laramie's energy balance leans toward cold weather: 8,150 annual heating degree days against 155 for cooling. Its 43.8°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 129 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.
