Climate Insight: Alpine, AK
The NOAA 1991–2020 climate normals describe Alpine, Alaska as a location with an annual average temperature of 14°F, ranging from a mean daily high of 20°F to a mean daily low of 8°F. July is typically the warmest month of the year, while January is the coldest. These thirty-year averages, computed from station USC00500235, 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. Alpine receives roughly 8.1 inches of precipitation each year, predominantly as rainfall. Growing-season length varies with elevation and microclimate, with the last spring freeze near N/A and the first fall freeze near N/A. For energy use, 18,406 heating degree days and 2 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Alpine scores 37/100 (Below Average), 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.
