The year, day by day
Dworshak Fish Hatchery works both ends of the calendar. Normal highs climb to 93°F by July 29 and hold at or above 90°F on 32 dates, then normal lows drop to freezing or below on 114 dates, bottoming at 27°F around December 24.
When the heat sits
Normal highs reach 90°F from July 16 through August 16, covering 32 dates. The broader mild season, normal highs of 70°F or more, runs May 8 to October 4.
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 11, then returns to freezing around November 19, covering 114 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 26, when 54% of years recorded at least a hundredth of an inch. The driest is July 31 at 11%. Summed across the calendar, that is about 141 wet dates a year.
The widest day
July 31 carries the biggest normal gap between afternoon and dawn, 37°F between the normal high and the normal low.

Dworshak Fish Hatchery spreads its precipitation across the year
Neither half of the year dominates here: June through August take 13% of the annual total and December through February 34%, with neither reaching the 35% that would mark a distinct wet season. Dworshak Fish Hatchery has no dry season to plan around, though it does carry a 38.9°F seasonal spread.
The gap between the wettest and driest month still matters: November averages 3.2" and August 0.7". The three wettest months together take 37% of the year, against the 25% a perfectly flat distribution would give them.
Shares are computed from this station's own 1991-2020 monthly precipitation normals. "Spread across the year" means neither the June-August nor the December-February share reaches 35%; it describes an average year, not the variability of any single one.
Rain reaches Dworshak Fish Hatchery in small, frequent amounts
Dworshak Fish Hatchery records about 140 days with measurable precipitation a year and 26.1" in total, which works out to roughly 0.19 inches on an average wet day. Precipitation on 38% of all days, arriving that lightly, is the damp many-grey-days pattern rather than the storm-driven one.
Places in this band read as wetter than their annual totals suggest, because what people notice is the number of overcast days, not the depth in the gauge.
- Most wet days: January, about 17 of them.
- Fewest: August, about 4.
- Average depth per wet day: 0.19 inches.
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 Dworshak Fish Hatchery
Dworshak Fish Hatchery averages 17.5 inches of snowfall a year, with December the snowiest month on the normals, spread across roughly 9 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: 17.5 inches of depth.
- Days recording measurable snow: about 9 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 7% 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 Dworshak Fish Hatchery; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
