The year, day by day
Dunsmuir Trtmt PL works both ends of the calendar. Normal highs climb to 91°F by July 22 and hold at or above 90°F on 28 dates, then normal lows drop to freezing or below on 98 dates, bottoming at 30°F around January 1.
When the heat sits
Normal highs reach 90°F from July 13 through August 9, covering 28 dates. The broader mild season, normal highs of 70°F or more, runs May 6 to October 17.
This counts calendar dates whose 1991–2020 normal high reaches 90°F. It is a smaller number than the 90°F+ day counts in the monthly table above, which measure how often the threshold was actually crossed in a typical year. A date can average 88°F and still exceed 90°F in half of all years.
The freezing stretch
The normal low stays at or below 32°F into March 2, then returns to freezing around November 26, covering 98 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 January 21, when 47% of years recorded at least a hundredth of an inch. The driest is July 30 at 4%. Summed across the calendar, that is about 100 wet dates a year.
The widest day
September 1 carries the biggest normal gap between afternoon and dawn, 38°F between the normal high and the normal low.

Where Dunsmuir Trtmt PL Stands Nationally
This is one of the wettest normals climates ranked: about 63 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 38°F, sharper than nine in ten ranked stations see.
Dunsmuir Trtmt PL earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Dunsmuir Trtmt PL's wet season runs through the cold months
December, January and February carry 54% of the year's precipitation here, while June through August contribute 3%. 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 33°F seasonal spread.
- Wettest month
- December, 12.6"
- Driest month
- July, 0.1"
- Wettest three months
- December, January, February (54% 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 Dunsmuir Trtmt PL, it arrives in quantity
63.3" of precipitation falls across only about 98 wet days here, averaging 0.64 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 98 a year, 27% of all days
- Average depth per wet day
- 0.64 inches
- Most wet days
- January, about 15
- Fewest wet days
- July, about 1
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 Dunsmuir Trtmt PL
Dunsmuir Trtmt PL averages 26.7 inches of snowfall a year, with January the snowiest month on the normals, spread across roughly 12 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: 26.7 inches of depth.
- Days recording measurable snow: about 12 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 4% 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.

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 Dunsmuir Trtmt PL; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
