The months above are NOAA's gridded normals at Wyoming's center.
What is each month like in Wyoming?
NOAA's grid estimates the normals every 5 km or so from the stations around each point, terrain included. It smooths between stations, so night lows at the heart of a large city can run warmer than the grid shows: at five big-city airports we compared, the grid's highs were within about 1°F of the station and its lows 1-6°F cooler. The nearest record's high and low are beside each month.

What do the station records around Wyoming say?
Each row is a NOAA station's own 1991-2020 normals, with the snow and frost dates the grid does not give. A record downhill or nearer the coast than the city can run warmer, one uphill cooler: compare the elevations.
| Record | Where | Elevation | Year | Jan low | Jul high | Precip. | Snow | Last frost |
|---|---|---|---|---|---|---|---|---|
| East Grand Rapids | 6 mi NE | 746 ft | 48.0°F | 17°F | 82°F | 39.6 | 75 | May 6 |

How much snow, how late a frost, what zone and how much sun in Wyoming?
NOAA's grid gives no snow, frost dates or records, so these come from the nearest station record, East Grand Rapids (6 miles NE, 746 ft). It gets 75 inches of snow in a normal year. The last spring frost (32°F) comes after May 6 in half of years and the first autumn frost before October 10.
The USDA's 2023 Plant Hardiness Zone Map puts Wyoming in zone 6a across its 4 ZIP code areas.
Over a year 70% of the sunlight that would reach the ground under clear skies gets through the clouds in the area (3.8 kWh per square metre a day, NASA POWER 2001-2020); July is the sunniest month (81%) and December the cloudiest (50%).
East Grand Rapids's page has its months, frost probabilities, records by month and recent years. NOAA's grid has monthly figures only, so there are no day-by-day month pages for Wyoming; the nearest record's month pages have them.
