The year, day by day
Summer here tops out rather than builds: the warmest normal high is 87°F around July 27, short of 90°F on every date, while 144 dates carry a normal low at or below freezing, the coldest 24°F near January 1.
The freezing stretch
The normal low stays at or below 32°F into March 28, then returns to freezing around November 6, covering 144 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 December 27, when 55% of years recorded at least a hundredth of an inch. The driest is July 31 at 10%. Summed across the calendar, that is about 116 wet dates a year.
The widest day
July 26 carries the biggest normal gap between afternoon and dawn, 30°F between the normal high and the normal low.

Stehekin's wet season runs through the cold months
December, January and February carry 48% of the year's precipitation here, while June through August contribute 5%. 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 41.6°F seasonal spread.
- Wettest month
- December, 7.2"
- Driest month
- July, 0.5"
- Wettest three months
- December, January, November (56% 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.
How Stehekin's precipitation splits across the calendar
About 116 days a year record measurable precipitation here, carrying 36.9" between them, or roughly 0.32 inches on a typical wet day. That sits in the middle band: neither the many-light-days pattern of the Pacific Northwest and the Great Lakes, nor the few-heavy-events pattern of the Gulf and the desert Southwest.
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year and say nothing about the heaviest single storm on record.
Winter brings real snow to Stehekin
Stehekin averages 129.7 inches of snowfall a year, with December the snowiest month on the normals, spread across roughly 34 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: 129.7 inches of depth.
- Days recording measurable snow: about 34 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 35% 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 Stehekin
heating led · moderate · mid swing
Stehekin's energy balance leans toward cold weather: 6,661 annual heating degree days against 432 for cooling. Its 41.6°F seasonal range still makes the monthly rows more useful than the annual average alone.
Stehekin's frost-free season lasts about 173 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
-

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Stehekin's primary station: STEHEKIN 4 NW (USC00458059). 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 Stehekin; 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 Stehekin comes from its primary NOAA station record.
