What Boise Lucky Peak Dam's climate means for you
Boise Lucky Peak Dam runs 53°F a year - peaking in July, coldest in December.
These are 30-year NOAA normals (1991–2020) - the typical year, not a forecast for any specific season.
Based on station USC00101018 feeding NOAA's 1991–2020 climate normals, Boise Lucky Peak Dam, Idaho averages 53°F a year, ranging from a mean daily high of 65°F to a mean daily low of 40°F. July is typically the warmest month of the year, while December is the coldest. Because these figures are thirty-year averages rather than any single year's readings, they describe the typical month, not a forecast for it.
Rainfall (and snow, where it falls) shapes day-to-day life here as much as temperature does. Boise Lucky Peak Dam sees about 15.1 inches of precipitation a year, predominantly as rainfall. The frost-free season averages 175 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near April 30 and the first fall freeze near October 22. On the energy side, 5,360 heating degree days and 926 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Boise Lucky Peak Dam scores 54/100 (Moderate), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. The monthly tables above are the practical planning tool: mild highs and lows land in the shoulder seasons, July-driven heat peaks in summer, and December-driven cold sets in over deep winter. These are thirty-year averages, not a forecast - any single year can run warmer, wetter, drier, or cooler than the normal.
