The year, day by day
Great Salt Plains Dam works both ends of the calendar. Normal highs climb to 96°F by July 18 and hold at or above 90°F on 82 dates, then normal lows drop to freezing or below on 100 dates, bottoming at 23°F around January 16.
When the heat sits
Normal highs reach 90°F from June 14 through September 3, covering 82 dates. The broader mild season, normal highs of 70°F or more, runs April 14 to October 24.
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 2, then returns to freezing around November 24, covering 100 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 May 24, when 30% of years recorded at least a hundredth of an inch. The driest is January 11 at 11%. Summed across the calendar, that is about 69 wet dates a year.
The widest day
October 13 carries the biggest normal gap between afternoon and dawn, 26°F between the normal high and the normal low.

Where Great Salt Plains 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.

Great Salt Plains Dam runs a summer-peaked wet season
36% of Great Salt Plains 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 May at 4.8", on a wide 47.9°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: May, June, August, taking 40% of the annual total between them.
- Driest month: January at 0.9".
- Winter share: 11% 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.
When it rains in Great Salt Plains Dam, it arrives in quantity
33.5" of precipitation falls across only about 68 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 68 a year, 19% of all days
- Average depth per wet day
- 0.49 inches
- Most wet days
- May, about 9
- Fewest wet days
- January, about 3
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.
Snow reaches Great Salt Plains Dam, but rarely amounts to much
The normals record 10.2 inches of snow a year here, most likely in December. That is a real but marginal amount: enough that snow is part of the local record, not enough to define the winter.
A figure in this range usually reflects a handful of events that melt quickly rather than a season of accumulation; about 4 days a year record any measurable snow at all.
NOAA 1991-2020 normals. An average across thirty years can smooth away a single heavy winter, so a small annual figure does not mean a significant snowfall is impossible.

Data-derived climate profile
How Great Salt Plains Dam's climate pattern fits together
heating led · moderate · mid swing
Great Salt Plains Dam's energy balance leans toward cold weather: 4,063 annual heating degree days against 1,985 for cooling. Its 47.9°F seasonal range still makes the monthly rows more useful than the annual average alone.
Great Salt Plains Dam's frost-free season lasts about 210 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 Great Salt Plains Dam's middle-range seasonal profile. The measured spread is 47.9°F. The annual average is 59°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Great Salt Plains Dam's 33.5 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Annual snowfall totals 10.2 inches. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
These labels group NOAA 1991-2020 normals from Great Salt Plains 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 Great Salt Plains Dam, not an official NOAA class or a year-ahead forecast.

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 Great Salt Plains Dam; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
