The year, day by day
Boise Lucky Peak Dam works both ends of the calendar. Normal highs climb to 95°F by July 25 and hold at or above 90°F on 45 dates, then normal lows drop to freezing or below on 121 dates, bottoming at 24°F around December 22.
When the heat sits
Normal highs reach 90°F from July 7 through August 20, covering 45 dates. The broader mild season, normal highs of 70°F or more, runs May 5 to October 10.
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 13, then returns to freezing around November 14, covering 121 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.
The widest day
July 14 carries the biggest normal gap between afternoon and dawn, 34°F between the normal high and the normal low.

Where Boise Lucky Peak Dam Stands Nationally
A drier-than-most normal water year — around 15 inches, below what four out of five ranked stations collect.
Daily temperature swings run wider than most of the country, peaking near 34°F between the normal high and low.
Boise Lucky Peak Dam earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.
Monthly Precipitation
Average monthly rainfall
Boise Lucky Peak Dam's wet season runs through the cold months
December, January and February carry 37% of the year's precipitation here, while June through August contribute 11%. 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 43.3°F seasonal spread.
- Wettest month
- December, 2.3"
- Driest month
- August, 0.3"
- Wettest three months
- December, January, May (41% 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.

Data-derived climate profile
How Boise Lucky Peak Dam's climate pattern fits together
heating led · dry · mid swing
Boise Lucky Peak Dam's energy balance leans toward cold weather: 5,360 annual heating degree days against 926 for cooling. Its 43.3°F seasonal range still makes the monthly rows more useful than the annual average alone.
Boise Lucky Peak Dam's frost-free season lasts about 175 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 Boise Lucky Peak Dam's middle-range seasonal profile. The measured spread is 43.3°F. The annual average is 53°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Boise Lucky Peak Dam's cold-season load does not imply a wet climate. Annual precipitation is 15.1 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.
These labels group NOAA 1991-2020 normals from Boise Lucky Peak 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 Boise Lucky Peak 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 Boise Lucky Peak Dam's primary station: BOISE LUCKY PEAK DAM (USC00101018). 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 Boise Lucky Peak 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 Boise Lucky Peak Dam comes from its primary NOAA station record.
