Milwaukee, WI – Dangerous heat and humidity will grip southeastern Wisconsin on Friday, pushing heat indices to 100°F and creating a high-risk afternoon for anyone hitting area beaches. Swimmers at Ozaukee and Sheboygan County beaches face a moderate threat from breaking waves and strong currents later today into tonight.
According to the National Weather Service, the combination of high temperatures and humidity will make outdoor activities risky, especially for sensitive groups. Residents should plan for limited outdoor exposure and stay hydrated. The heat is expected to last through Friday evening, with some relief possible overnight. Another round of thunderstorms is set to move in by Saturday afternoon, bringing multiple waves of rain and a renewed threat of flooding, especially if storms linger over the same spots. A few of these storms could turn severe, and heavy rainfall may make low-lying roads hazardous.
Swimmers should avoid piers, breakwalls, and river outlets today and Saturday, as breaking waves and rip currents could lead to dangerous conditions. High swim risk will continue at Lake Michigan beaches into the weekend. If you must be outdoors, try to schedule activities for the early morning or after sunset. Those with weekend plans should be alert for changing conditions, especially Saturday afternoon and evening when storms are most likely.
Hot, humid weather and the risk of thunderstorms remain a pattern through early next week, with more advisories possible as conditions develop.
