The NOAA 1991–2020 climate normals describe King Salmon, Alaska as a location with an annual average temperature of 37°F, ranging from a mean daily high of 44°F to a mean daily low of 29°F. July is typically the warmest month of the year, while January is the coldest. These thirty-year averages, computed from 2 weather stations, smooth out year-to-year variability and give a baseline expectation for typical conditions in any given month.
Precipitation patterns matter as much as temperature for anyone planning to live, garden, or travel here. King Salmon receives roughly 21.4 inches of precipitation each year, with 47.4 inches typically falling as snow. Growing-season length varies with elevation and microclimate, with the last spring freeze near May 26 and the first fall freeze near September 15. For energy use, 10,385 heating degree days and 3 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, King Salmon scores 52/100 (Moderate), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. Use the monthly tables above to plan around specific windows — shoulder seasons for mild highs and lows, peak summer for July-driven heat, or deep winter for January-driven cold. All figures here are thirty-year averages: any single year may run warmer, wetter, drier, or cooler than the normal, so treat them as planning guidance rather than forecasts.
