The year, day by day
The year in Cougar Dam runs from a mild 38°F around December 22 to 92°F at the peak near July 27, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from July 17 through August 12, covering 27 dates. The broader mild season, normal highs of 70°F or more, runs May 2 to October 12.
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.
No freezing date
Not one calendar date in the 1991–2020 record carries a normal low at or below 32°F. The coldest normal low of the year is 38°F around December 22.
Where the wet dates fall
The likeliest wet date is March 24, when 68% of years recorded at least a hundredth of an inch. The driest is July 27 at 6%. Summed across the calendar, that is about 160 wet dates a year.
The widest day
August 3 carries the biggest normal gap between afternoon and dawn, 32°F between the normal high and the normal low.

Where Cougar Dam Stands Nationally
This is one of the wettest normals climates ranked: about 78 inches of precipitation in a normal year, a total fewer than one station in ten surpasses.
Cougar Dam earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.

Cougar Dam's wet season runs through the cold months
December, January and February carry 42% 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 30.5°F seasonal spread.
- Wettest month
- January, 13.0"
- Driest month
- August, 0.6"
- Wettest three months
- January, December, 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 Cougar Dam, it arrives in quantity
77.7" of precipitation falls across only about 159 wet days here, averaging 0.49 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 159 a year, 44% of all days
- Average depth per wet day
- 0.49 inches
- Most wet days
- March, about 20
- Fewest wet days

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.

Data-derived climate profile
How Cougar Dam's climate pattern fits together
heating led · wet · mid swing
Cougar Dam's energy balance leans toward cold weather: 3,663 annual heating degree days against 893 for cooling. Its 30.5°F seasonal range still makes the monthly rows more useful than the annual average alone.
The frost-free window extends for about 273 days. That is a long calendar measure, but it is not a forecast and does not combine heat, rainfall, soil, or local elevation into a planting recommendation.
July and December mark the typical warm and cold ends of the calendar in Cougar Dam's middle-range seasonal profile. The measured spread is 30.5°F. The annual average is 57°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Alongside its heating load, Cougar Dam carries 77.7 inches of precipitation in a normal year, inside PlainClimate's wet range. Snowfall is not added to the interpretation because its annual value is missing. That distinction matters because a wet annual total can arrive as rain, snow, or a mixture at different times.
These labels group NOAA 1991-2020 normals from Cougar Dam's primary station, so the winter figures are a thirty-year average and not a floor: a single hard season can run well below them. Treat each band as a descriptive range for Cougar Dam, not an official NOAA class or a year-ahead forecast.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Cougar Dam's primary station: COUGAR DAM (USC00351914). 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 Cougar Dam; 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 Cougar Dam comes from its primary NOAA station record.
