Weather extremes
How extreme does Anchorage's weather get?
The hottest, coldest, wettest and snowiest days Anchorage has recorded — the outer limits of what its weather can do, and how far they sit beyond a normal day.
The four kinds of extreme
The hottest, coldest, wettest and snowiest single days Anchorage has recorded — each shown against what a normal day that time of year looks like.
That is about 24°F hotter than a normal July afternoon in Anchorage (typical high near 66°F).
The three most extreme on record
About 45°F colder than a normal January night in Anchorage (typical low near 11°F).

About 94% of a typical August's rain in a single day (Anchorage averages roughly 2.9 in across the month).
The three most extreme on record
Close to a whole typical March's snow in one day (Anchorage averages about 11 in across the month).

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.
Anchorage's record heat sits well above even a hot day for the season — July's 90°F is about 24°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.
