Warming context for Fairbanks

Methodology

Fairbanks's NOAA 1991-2020 normal sits inside a longer story: U.S. land temperatures have been tracking (and drifting from) the global mean since 1900, and the chart below shows that spread, with the most recent decade running warmer than the 30-year mean.

What Fairbanks's climate means for you

Fairbanks runs 28°F a year - peaking in July, coldest in January.

  • Gardeners get about 115 frost-free days, with the last spring freeze near May 16 - plan the planting calendar around it, not the regional average.
  • Energy bills track 13,644 heating and 40 cooling degree days a year, higher means the furnace or AC runs more.
  • Comparing places to live? Line this city up against nearby cities and the national rankings. See rankings

Climate Insight: Fairbanks, AK

The NOAA 1991–2020 climate normals describe Fairbanks, Alaska as a location with an annual average temperature of 28°F, ranging from a mean daily high of 37°F to a mean daily low of 18°F. July is typically the warmest month of the year, while January is the coldest. These thirty-year averages, computed from station USC00502965, smooth out year-to-year variability and give a baseline expectation for typical conditions in any given month.

Beyond temperature, Fairbanks averages 12.2 inches of precipitation annually, with 59.6 inches typically falling as snow - a real factor for anyone planning to live, garden, or travel here. The frost-free season averages 115 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near May 16 and the first fall freeze near September 8. Turning to energy use, 13,644 heating degree days and 40 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.

On PlainClimate's composite comfort index, Fairbanks scores 34/100 (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.
