Climate Chart of Fairbanks, Alaska, USA

Monthly data: Temperature °C, Rain (mm), Sunshine (h) · 2013–2023

Climate overview

Temperature

Monthly mean temperatures reach their lowest point in January, at -17.1 °C, and their highest in July, at 17.6 °C. These are averages for each month, not daytime maximum temperatures, so they describe the broad temperature pattern rather than the warmth or cold of any particular afternoon. The unweighted mean of the monthly means is -0.2 °C; it is not a day-weighted annual average.

Sunshine

Mean daily sunshine duration peaks in June at 13.97 hours/day, while the lowest monthly mean is in December at 1.34 hours/day. The unweighted mean of the monthly values is 7.28 hours/day. These averages can help set expectations for sunshine during outdoor plans, but sunshine duration is not the same as day length and cannot predict the conditions on a specific day.

Rain

Mean daily rainfall is lowest in February / November, at 0.02 mm/day, and reaches its highest monthly mean in August, at 2.73 mm/day. The unweighted mean across monthly means is 0.84 mm/day. These are daily average amounts, not monthly totals: lower average rainfall does not guarantee dry days, and the figures do not tell you how frequently rain occurs or how it is distributed within a month.

Snow

Mean daily snowfall reaches its highest monthly average in December, at 5.94 mm/day; the unweighted mean across monthly means is 2.45 mm/day. These figures describe average daily snowfall amounts, not monthly totals. They do not establish how many days have snow, how deep it becomes, whether snow cover persists, or whether conditions suit skiing.

Best Travel Time Guide for Fairbanks, Alaska, USA: Ideal Seasons and Weather Insights

If cooler monthly mean conditions are your priority, use January and its mean of -17.1 °C as a reference when planning; this is a monthly average, not a forecast or a daytime high. For visitors prioritising lower average rainfall, February / November is the relevant option, with mean daily rainfall of 0.02 mm/day. That average cannot guarantee dry weather or indicate how often rain falls, so keep plans flexible. For rain preparation, note that the highest monthly mean daily rainfall occurs in August, at 2.73 mm/day; packing suitable rain protection is a practical precaution, not a prediction of rain on your travel dates. For outdoor sightseeing planned around sunshine, June has the highest mean daily sunshine duration at 13.97 hours/day, while December has the lowest at 1.34 hours/day. Sunshine hours describe average duration, not daylight length or guaranteed clear skies. Snowfall averages may also inform winter preparation: December has the highest mean daily snowfall at 5.94 mm/day. This does not show how many snowy days to expect, snow depth or cover, or whether skiing conditions will be available, so check date-specific conditions before making plans.
