The year, day by day
Summer here tops out rather than builds: the warmest normal high is 86°F around July 24, short of 90°F on every date, while 168 dates carry a normal low at or below freezing, the coldest 17°F near December 25.
The freezing stretch
The normal low stays at or below 32°F into April 10, then returns to freezing around October 26, covering 168 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 24, when 35% of years recorded at least a hundredth of an inch. The driest is January 16 at 11%. Summed across the calendar, that is about 73 wet dates a year.
The widest day
July 7 carries the biggest normal gap between afternoon and dawn, 27°F between the normal high and the normal low.

Where Cody Stands Nationally
Aridity defines the water calendar: about 12 inches in a normal year lands this among the driest tenth of ranked stations.
Cody earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.

Cody 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 11%, with neither reaching the 35% that would mark a distinct wet season. Cody has no dry season to plan around, though it does carry a 43.3°F seasonal spread.
The gap between the wettest and driest month still matters: May averages 2.2" and January 0.4". The three wettest months together take 45% 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.
Cody is dry, and what does fall arrives gently
Only about 72 days a year record measurable precipitation here, 20% of the calendar, and they carry 11.5" between them. At roughly 0.16 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 10 wet days; the driest is January at about 3.
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 Cody
Cody averages 45.0 inches of snowfall a year, with February the snowiest month on the normals, spread across roughly 19 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: 45.0 inches of depth.
- Days recording measurable snow: about 19 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 39% 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 Cody
heating led · dry · mid swing
Cody's energy balance leans toward cold weather: 7,049 annual heating degree days against 464 for cooling. Its 43.3°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 142 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.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Cody's primary station: CODY (USC00481840). 3 NOAA stations are mapped to the Cody area; the primary station's record is used for consistency. For informational purposes only.
Place identity: U.S. Census Bureau 2024 Gazetteer places. The 2024 Census Gazetteer identifies the exact name-and-state match as an incorporated place (GEOID 5615760). Match rule for Cody: exact normalized name + state only, no fuzzy expansion, so nearby differently spelled facilities stay unmatched.
