Weather extremes

How extreme does Kotzebue's weather get?

The hottest, coldest, wettest and snowiest days Kotzebue has recorded — the outer limits of what its weather can do, and how far they sit beyond a normal day.

Based on 50+ years of daily weather observations (1971–present), from the Kotzebue Ap station 1 km away. Updated through June 2026 — an all-time extreme only changes when a more extreme day actually occurs, so some dates are old. That is normal, not stale data.

The four kinds of extreme

The hottest, coldest, wettest and snowiest single days Kotzebue has recorded — each shown against what a normal day that time of year looks like.

🔥 Hottest day
85°F Jun 22, 1991

That is about 32°F hotter than a normal June afternoon in Kotzebue (typical high near 53°F).

How hot and cold it gets, month by month

The shaded band is the normal range of daily temperatures for each month. The dots show the most extreme it has ever been — so you can see how far beyond a normal day the records really sit.

Kotzebue's record heat sits well above even a hot day for the season — June's 85°F is about 32°F beyond a normal hot afternoon. Its record cold is just as far below a normal winter night — the dots mark how rare each extreme really is.

In plain terms

In a normal year, Kotzebue's warmest days reach the low 60s°F and its coldest nights drop to the low 0s°F. But across the record it has gone as high as 85°F and as low as −49°F. A single day has delivered over 2 inches of rain or close to 13 inches of snow. Those are the outer edges worth knowing if you are moving here, planning a trip, or thinking about a house.
