Weather extremes
How extreme does Bismarck's weather get?
The hottest, coldest, wettest and snowiest days Bismarck 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 Bismarck has recorded — each shown against what a normal day that time of year looks like.
That is about 27°F hotter than a normal July afternoon in Bismarck (typical high near 85°F).
The three most extreme on record
About 46°F colder than a normal January night in Bismarck (typical low near 2°F).
The three most extreme on record
More rain in a single day than Bismarck usually gets in the whole month of August (typical August total about 2.5 in).
The three most extreme on record
Close to a whole typical April's snow in one day (Bismarck averages about 5 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.
Bismarck's record heat sits well above even a hot day for the season — July's 112°F is about 27°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.
