The year, day by day
Summer here tops out rather than builds: the warmest normal high is 71°F around July 29, short of 90°F on every date, while 160 dates carry a normal low at or below freezing, the coldest 24°F near December 22.
The freezing stretch
The normal low stays at or below 32°F into April 11, then returns to freezing around November 4, covering 160 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 November 24, when 67% of years recorded at least a hundredth of an inch. The driest is August 1 at 19%. Summed across the calendar, that is about 187 wet dates a year.
The widest day
July 22 carries the biggest normal gap between afternoon and dawn, 19°F between the normal high and the normal low.

Where Stampede Pass Stands Nationally
This is one of the wettest normals climates ranked: about 85 inches of precipitation in a normal year, a total fewer than one station in ten surpasses.
Among the steadiest day-night climates ranked: even the widest normal daily swing holds to roughly 19°F.
Stampede Pass earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Stampede Pass's wet season runs through the cold months
December, January and February carry 38% of the year's precipitation here, while June through August contribute 7%. That is the cool-season-dominant pattern of the West Coast and the higher inland West, where storm tracks swing south in winter and summer turns dry; the thermometer meanwhile shows a 31.9°F seasonal spread.
- Wettest month
- November, 13.7"
- Driest month
- July, 1.3"
- Wettest three months
- November, December, January (45% of the year)
Shares are computed from this station's own 1991-2020 monthly precipitation normals. A cool-season label means the December-February share reaches 35%. Where snow falls, the monthly figures above report liquid-equivalent precipitation, so a wet winter month is not necessarily a rainy one.
When it rains in Stampede Pass, it arrives in quantity
85.0" of precipitation falls across only about 187 wet days here, averaging 0.45 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.
- Days with measurable precipitation
- about 187 a year, 51% of all days
- Average depth per wet day
- 0.45 inches
- Most wet days
- November, about 21

A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year, and a per-day average is not a forecast of any individual storm.

Data-derived climate profile
How Stampede Pass's climate pattern fits together
heating led · wet · mid swing
Stampede Pass's energy balance leans toward cold weather: 8,316 annual heating degree days against 100 for cooling. Its 31.9°F seasonal range still makes the monthly rows more useful than the annual average alone.
Stampede Pass's frost-free season lasts about 156 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
August and December mark the typical warm and cold ends of the calendar in Stampede Pass's middle-range seasonal profile. The measured spread is 31.9°F. The annual average is 42°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Alongside its heating load, Stampede Pass carries 85.0 inches of precipitation in a normal year, inside PlainClimate's wet range. Snowfall is not added to the interpretation because its annual value is missing. That distinction matters because a wet annual total can arrive as rain, snow, or a mixture at different times.
These labels group NOAA 1991-2020 normals from Stampede Pass's primary station, so the winter figures are a thirty-year average and not a floor: a single hard season can run well below them. Treat each band as a descriptive range for Stampede Pass, not an official NOAA class or a year-ahead forecast.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Stampede Pass's primary station: STAMPEDE PASS (USW00024237). For informational purposes only.
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 Stampede Pass; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
On this page every temperature, precipitation, and derived score for Stampede Pass comes from its primary NOAA station record.
