Milwaukee started Monday, July 13, 2026, on a deceptively pleasant note, with clear skies and a mild 72°F at General Mitchell International Airport. Do not get used to it. By midweek, highs are headed for the mid 90s and the "feels-like" temperature could push past 100°F by Tuesday, July 14, 2026. Overnight lows will stay muggy, offering little relief for anyone without solid air conditioning.
What To Expect This Week
According to the National Weather Service Milwaukee/Sullivan, the forecast calls for a high near 95°F today (Monday, July 13) with a southwest wind around 5 to 10 mph and heat index values up to about 98°F. Tuesday, July 14 is expected to be hotter, with a high near 98°F and heat index readings that could reach roughly 102°F. The weather should stay generally dry through Thursday, before isolated shower and thunderstorm chances creep back in late in the week. Forecasters urge residents to take the hottest afternoons seriously, since prolonged exposure can lead to heat illness.
Timing And Outdoor Plans
The peak heat window each day will run from roughly 1 to 6 p.m., when humidity will make mid day temperatures feel even more oppressive. If you have to be outside, try to shift heavy work or exercise into the cooler morning hours, drink water often, and keep an eye out for dizziness, a rapid pulse, or confusion, especially in vulnerable neighbors. Lakeside neighborhoods along Lake Michigan might luck into a few degrees of relief if a lake breeze sets up later in the week.
Where To Cool Off
The City of Milwaukee keeps an updated list of cooling centers, air conditioned libraries, and splash pads; check the City of Milwaukee cooling sites page or call 2-1-1 to find the closest option. Anyone who relies on electricity for medical equipment should line up a backup plan in case of power outages, and officials stress that children and pets should never be left in parked cars.
