The year, day by day
Summer here tops out rather than builds: the warmest normal high is 87°F around July 24, short of 90°F on every date, while 198 dates carry a normal low at or below freezing, the coldest 12°F near January 16.
The freezing stretch
The normal low stays at or below 32°F into April 26, then returns to freezing around October 12, covering 198 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 6, when 32% of years recorded at least a hundredth of an inch. The driest is July 3 at 13%. Summed across the calendar, that is about 92 wet dates a year.
The widest day
July 14 carries the biggest normal gap between afternoon and dawn, 37°F between the normal high and the normal low.

Where Deer Creek Dam Stands Nationally
Winters bite deep and often: the normal nightly low dips to freezing or below on around 198 nights a year, placing this among the most frost-prone tenth of ranked stations.
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.

Deer Creek Dam'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 13%. 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 43.8°F seasonal spread.
- Wettest month
- January, 3.1"
- Driest month
- July, 0.7"
- Wettest three months
- January, December, February (38% 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 Deer Creek Dam's precipitation splits across the calendar
About 92 days a year record measurable precipitation here, carrying 21.7" between them, or roughly 0.24 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 Deer Creek Dam
Deer Creek Dam averages 73.9 inches of snowfall a year, with January the snowiest month on the normals, spread across roughly 25 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: 73.9 inches of depth.
- Days recording measurable snow: about 25 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 34% 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 Deer Creek Dam
heating led · moderate · mid swing
Deer Creek Dam's energy balance leans toward cold weather: 7,400 annual heating degree days against 207 for cooling. Its 43.8°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 118 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 Deer Creek Dam; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
