The year, day by day
Summer here tops out rather than builds: the warmest normal high is 84°F around July 26, short of 90°F on every date, while 160 dates carry a normal low at or below freezing, the coldest 27°F near January 1.
The freezing stretch
The normal low stays at or below 32°F into April 13, then returns to freezing around November 6, 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 March 27, when 65% of years recorded at least a hundredth of an inch. The driest is July 30 at 10%. Summed across the calendar, that is about 165 wet dates a year.
The widest day
July 30 carries the biggest normal gap between afternoon and dawn, 37°F between the normal high and the normal low.

Where Marion Forks Fish Hatchery Stands Nationally
This is one of the wettest normals climates ranked: about 74 inches of precipitation in a normal year, a total fewer than one station in ten surpasses.
Day-to-night contrast is extreme by national standards — the widest normal daily swing reaches about 37°F, sharper than nine in ten ranked stations see.
Marion Forks Fish Hatchery earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Marion Forks Fish Hatchery's wet season runs through the cold months
December, January and February carry 43% of the year's precipitation here, while June through August contribute 6%. 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 31.4°F seasonal spread.
- Wettest month
- December, 12.4"
- Driest month
- August, 0.7"
- Wettest three months
- December, January, November (46% 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 Marion Forks Fish Hatchery, it arrives in quantity
74.1" of precipitation falls across only about 165 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 165 a year, 45% of all days
- Average depth per wet day
- 0.45 inches
- Most wet days
- March, about 20
- Fewest wet days
- July, about 4
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.
Winter brings real snow to Marion Forks Fish Hatchery
Marion Forks Fish Hatchery averages 85.2 inches of snowfall a year, with January the snowiest month on the normals, spread across roughly 28 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: 85.2 inches of depth.
- Days recording measurable snow: about 28 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 12% of the year's precipitation.

Snow and freeze rhythm
When cold and snow define Marion Forks Fish Hatchery
heating led · wet · mid swing
Marion Forks Fish Hatchery's energy balance leans toward cold weather: 6,647 annual heating degree days against 141 for cooling. Its 31.4°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 138 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.

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 Marion Forks Fish Hatchery; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
