The year, day by day
The year in Cooper Dam runs from a mild 33°F around January 9 to 95°F at the peak near July 31, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from June 18 through September 7, covering 82 dates. The broader mild season, normal highs of 70°F or more, runs March 27 to November 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.
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 33°F around January 9.
Where the wet dates fall
The likeliest wet date is February 24, when 33% of years recorded at least a hundredth of an inch. The driest is July 19 at 17%. Summed across the calendar, that is about 94 wet dates a year.
The widest day
October 6 carries the biggest normal gap between afternoon and dawn, 24°F between the normal high and the normal low.

Where Cooper Dam Stands Nationally
Heat is a defining feature of the normals calendar — the normal daily high reaches 90°F on roughly 82 days a year, more than four out of five ranked stations record.
Cooper Dam earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.

Cooper Dam spreads its precipitation across the year
Neither half of the year dominates here: June through August take 22% of the annual total and December through February 23%, with neither reaching the 35% that would mark a distinct wet season. Cooper Dam has no dry season to plan around, though it does carry a 39.7°F seasonal spread.
The gap between the wettest and driest month still matters: October averages 5.8" and August 3.0". The three wettest months together take 32% 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.
When it rains in Cooper Dam, it arrives in quantity
49.3" of precipitation falls across only about 94 wet days here, averaging 0.52 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.

- about 94 a year, 26% of all days
- Average depth per wet day

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 Cooper Dam's climate pattern fits together
mixed demand · wet · mid swing
Water is prominent even though neither heating nor cooling wholly defines the record. Cooper Dam averages 49.3 inches of precipitation a year. Snowfall is not added to the interpretation because its annual value is missing. The monthly table supplies the seasonal distribution hidden by that annual total.
July and January mark the typical warm and cold ends of the calendar in Cooper Dam's middle-range seasonal profile. The measured spread is 39.7°F. The annual average is 65°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Cooper Dam's normal, at 2,559 and 2,425 degree days respectively. Neither total exceeds the other by more than two to one, so the record is better read as a mixed-demand calendar than as heating-led or cooling-led.
The frost-free window extends for about 240 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.
These labels group NOAA 1991-2020 normals from Cooper Dam's primary station, where heating and cooling demand are close enough that neither season sets the character on its own. On a balanced station like Cooper Dam, the bands are descriptive ranges rather than an official NOAA classification or a forecast.

Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Cooper Dam's primary station: COOPER DAM (USC00411968). 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 Cooper 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 Cooper Dam comes from its primary NOAA station record.
