Milwaukee Weather: Sunny and hot most of the week

Published July 13, 2026 4:37 AM CDT

Forecast from FOX6 Chief Meteorologist Rob Haswell

Summer heat is settling in for a long stretch, with highs climbing into the 90s through the middle of the week and Tuesday looking like the hottest day.
While humidity won't be as oppressive as recent heat waves, it'll be high enough to push heat indices close to, or even briefly above, 100 degrees in many spots.
Sunshine and dry weather stick around through Thursday, making it a great week for outdoor plans if you can handle the heat. Our next chance of rain arrives Friday into Saturday as systems begin riding around the edge of the heat dome.
By Sunday, a somewhat cooler pattern should finally arrive, bringing a welcome break from the very hot weather.
