An Anchorage winter means heavy snow in some years, long dark stretches and cold snaps, with melt-and-refreeze at both ends of the season. Here's how a typical season tends to go. Any given year can differ.
Snowfall and freeze-thaw
| Place | Average seasonal snowfall | Freeze-thaw days a year |
|---|---|---|
| Anchorage (ANC airport) | 77.9 in | 73.7 |
Snowfall: NOAA NCEI 1991–2020 normals.1 Freeze-thaw days: our count of days with a high above 32°F and a low below 32°F in NOAA GHCN-Daily records, 1991–2020 average.2
The season, month by month
Freight comes north by sea. Line up sand, salt and liquids before freeze-up. Anchorage studs wait until October 1.
Days shorten to about five and a half hours near the solstice. Brine ahead while pavement is about 15°F or warmer.
Subzero mornings. Sand for traction, calcium or magnesium for spot melting.
Melt by day and refreeze at night. Sweep spring sand grit and watch drainage around piles.
