The year, day by day
Summer here tops out rather than builds: the warmest normal high is 90°F around July 17, short of 90°F on every date, while 179 dates carry a normal low at or below freezing, the coldest 12°F near January 20.
The freezing stretch
The normal low stays at or below 32°F into April 17, then returns to freezing around October 22, covering 179 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 June 3, when 33% of years recorded at least a hundredth of an inch. The driest is January 7 at 7%. Summed across the calendar, that is about 66 wet dates a year.
The widest day
September 24 carries the biggest normal gap between afternoon and dawn, 34°F between the normal high and the normal low.

Where Red Willow Dam Stands Nationally
Freezing is routine here by normals standards — the normal low reaches 32°F or colder on about 179 nights a year, more than most ranked stations.
Daily temperature swings run wider than most of the country, peaking near 34°F between the normal high and low.
Red Willow Dam earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Red Willow Dam runs a summer-peaked wet season
46% of Red Willow Dam's yearly precipitation falls in June, July and August alone, against the 25% an evenly spread year would give those three months. The wettest month is June at 3.3", on a wide 48.6°F gap between its warmest and coldest month. Warm-season convection and, across the Southwest, the North American monsoon produce this shape: rain arrives in short heavy bursts during the hottest part of the year rather than as long cool-season soaking.
- Wettest three months: June, July, August, taking 46% of the annual total between them.
- Driest month: January at 0.3".
- Winter share: 6% falls in December, January and February.
Shares are computed from this station's own 1991-2020 monthly precipitation normals. A summer-peaked label means the June-August share reaches 35%; it describes timing across an average year, not any single season, and says nothing about how heavy an individual storm can be.
How Red Willow Dam's precipitation splits across the calendar
About 66 days a year record measurable precipitation here, carrying 20.4" between them, or roughly 0.31 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.

Data-derived climate profile
How Red Willow Dam's climate pattern fits together
heating led · moderate · mid swing
Red Willow Dam's energy balance leans toward cold weather: 6,427 annual heating degree days against 828 for cooling. Its 48.6°F seasonal range still makes the monthly rows more useful than the annual average alone.
Red Willow Dam's frost-free season lasts about 151 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
July and January mark the typical warm and cold ends of the calendar in Red Willow Dam's middle-range seasonal profile. The measured spread is 48.6°F. The annual average is 50°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Red Willow Dam's 20.4 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Snowfall is not added to the interpretation because its annual value is missing. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
These labels group NOAA 1991-2020 normals from Red Willow 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 Red Willow 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 Red Willow Dam's primary station: RED WILLOW DAM (USC00257110). 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 Red Willow 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 Red Willow Dam comes from its primary NOAA station record.
