How extreme does Milwaukee's weather get?
The hottest, coldest, wettest and snowiest days Milwaukee has recorded — the outer limits of what its weather can do, and how far they sit beyond a normal day.

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.
Milwaukee's record heat sits well above even a hot day for the season — July's 101°F is about 16°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.
