The year, day by day
Fort Peck Pwr Plt works both ends of the calendar. Normal highs climb to 91°F by July 29 and hold at or above 90°F on 24 dates, then normal lows drop to freezing or below on 166 dates, bottoming at 7°F around January 12.
When the heat sits
Normal highs reach 90°F from July 20 through August 12, covering 24 dates. The broader mild season, normal highs of 70°F or more, runs May 14 to September 30.
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 April 9, then returns to freezing around October 27, covering 166 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 9, when 36% of years recorded at least a hundredth of an inch. The driest is November 26 at 13%. Summed across the calendar, that is about 72 wet dates a year.
The widest day
August 10 carries the biggest normal gap between afternoon and dawn, 32°F between the normal high and the normal low.

Fort Peck Pwr Plt runs a summer-peaked wet season
48% of Fort Peck Pwr Plt'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 2.7", on a wide 55.6°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, May, July, taking 56% of the annual total between them.
- Driest month: February at 0.3".
- Winter share: 7% 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.
Fort Peck Pwr Plt is dry, and what does fall arrives gently
Only about 73 days a year record measurable precipitation here, 20% of the calendar, and they carry 13.6" between them. At roughly 0.19 inches on an average wet day, this is not the damp drizzle of a marine climate; it is an arid record in which precipitation is both uncommon and light when it appears.
The wettest month by count is June at about 11 wet days; the driest is November at about 4.
A low per-event average in a dry record is a statement about typical days only. Arid regions can still take a large share of a year's total from a single convective storm, which a normal cannot show.
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year, not the extremes within it.

Scarce-water calendar
Where Fort Peck Pwr Plt's limited precipitation lands
heating led · dry · high swing
Winter and seasonal range jointly define this record. Fort Peck Pwr Plt logs 7,403 heating degree days, more than twice its 707 cooling total, while the typical coldest-to-warmest-month gap reaches 55.6°F. The annual mean therefore compresses two materially different seasons.
Only about 146 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.
July and January mark the typical warm and cold ends of the calendar in this dry, high-range record. The gap is 55.6°F, so a single annual figure is especially lossy; the annual average is 47°f. Compare monthly temperature and precipitation together before drawing a seasonal conclusion about Fort Peck Pwr Plt.
Fort Peck Pwr Plt's cold-season load does not imply a wet climate. Annual precipitation is 13.6 inches, which places the station in PlainClimate's dry range. Snowfall is not added to the interpretation because its annual value is missing. The snowfall and rainfall fields should be read separately rather than inferred from temperature.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Fort Peck Pwr Plt's primary station: FT PECK PWR PLT (USC00243176). 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 Fort Peck Pwr Plt; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
