Juneau's weather extremes
The hottest, coldest, wettest and snowiest days Juneau has recorded — the outer limits of what its weather can do. This station's daily record ended in 2021, so these are historical extremes from that period, not records updated to today.
The four kinds of extreme
The hottest, coldest, wettest and snowiest single days Juneau has recorded — each shown against what a normal day that time of year looks like.
That is about 26°F hotter than a normal August afternoon in Juneau (typical high near 62°F).
The three most extreme on record
About 56°F colder than a normal January night in Juneau (typical low near 27°F).
The three most extreme on record
About 73% of a typical November's rain in a single day (Juneau averages roughly 8.8 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.
Juneau's record heat sits well above even a hot day for the season — August's 88°F is about 26°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.
