The year, day by day
Lost Creek Dam works both ends of the calendar. Normal highs climb to 93°F by July 27 and hold at or above 90°F on 39 dates, then normal lows drop to freezing or below on 90 dates, bottoming at 30°F around December 22.
When the heat sits
Normal highs reach 90°F from July 12 through August 19, covering 39 dates. The broader mild season, normal highs of 70°F or more, runs May 7 to October 16.
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 1, then returns to freezing around December 3, covering 90 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 December 8, when 58% of years recorded at least a hundredth of an inch. The driest is August 5 at 6%. Summed across the calendar, that is about 127 wet dates a year.
The widest day
September 12 carries the biggest normal gap between afternoon and dawn, 40°F between the normal high and the normal low.

Lost Creek Dam's wet season runs through the cold months
December, January and February carry 44% of the year's precipitation here, while June through August contribute 6%. 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 32.3°F seasonal spread.
- Wettest month
- December, 6.3"
- Driest month
- August, 0.3"
- Wettest three months
- December, January, November (49% 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.
How Lost Creek Dam's precipitation splits across the calendar
About 127 days a year record measurable precipitation here, carrying 33.1" between them, or roughly 0.26 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.
Snow reaches Lost Creek Dam, but rarely amounts to much
The normals record 1.3 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 1 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 Lost Creek Dam's climate pattern fits together
heating led · moderate · mid swing
Lost Creek Dam's energy balance leans toward cold weather: 4,683 annual heating degree days against 564 for cooling. Its 32.3°F seasonal range still makes the monthly rows more useful than the annual average alone.
Lost Creek Dam's frost-free season lasts about 171 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
July and December mark the typical warm and cold ends of the calendar in Lost Creek Dam's middle-range seasonal profile. The measured spread is 32.3°F. The annual average is 54°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Lost Creek Dam's 33.1 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Annual snowfall totals 1.3 inches. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
These labels group NOAA 1991-2020 normals from Lost Creek 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 Lost Creek 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 Lost Creek Dam; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
