Milwaukee rolled out of bed Monday into air that already felt like a sauna, with temperatures around 72°F at General Mitchell International Airport and dewpoints in the low 70s turning the morning into a sticky slog. South winds were already on the move and temperatures are set to rocket into the 90s, kicking off a multi-day stretch of dangerously hot and humid weather across much of southeast Wisconsin.
What To Expect
According to NWS Milwaukee, an Extreme Heat Warning is in effect from noon Monday, June 29 through 7 p.m. Tuesday, June 30. High temperatures are expected to climb into the low to mid 90s, with inland heat index readings topping 100°F. South winds of 10 to 15 mph, with gusts up to 25 mph, will add to the discomfort for many neighborhoods away from the lake.
Afternoon Winds And Lakefront Cooling
During the afternoon, south-southwest winds of 10 to 15 mph with gusts as high as 25 mph will make it feel even hotter away from Lake Michigan. The lakefront should run a few degrees cooler than inland spots, but beachgoers should still be ready for hot, humid conditions along with stronger currents. Officials have highlighted higher swim risks at some county beaches, and Small Craft Advisories are possible on the lake.
Where To Cool Off
For anyone who needs a break from the heat, the City of Milwaukee keeps a list of air-conditioned cooling sites, including libraries, senior centers, and community centers that often open during heat events. Check hours and any capacity limits before heading out, since many locations operate on limited schedules. Details are available from the City of Milwaukee.
Heat Safety Tips
Residents are urged to take extra care in this kind of heat. Drink plenty of water, avoid strenuous outdoor work during the hottest afternoon hours, and check in on older neighbors and anyone without reliable air conditioning. Symptoms like dizziness, rapid heartbeat, fainting, or confusion are warning signs of heat illness, so move to a cool place and seek medical help if they appear, since conditions can worsen quickly. For outdoor plans, stick to early morning or evening if possible, and keep pets indoors during the peak heat of the day.
