Michigan is experiencing a hotter-than-normal summer in 2025, with temperatures soaring into the 90s for several days in a row and heat indices exceeding 100°F in many areas. With the risk of heat-related illnesses on the rise, it’s crucial to be prepared. Here are seven essential things to know to stay safe and healthy during Michigan’s summer heat.
1. Expect More Heat Waves and Higher Temperatures
This summer, Michigan is seeing temperatures one to two degrees hotter than average, with multiple 90-degree days in cities like Lansing, Detroit, Grand Rapids, and Flint. The heat index—a measure of how hot it feels when humidity is factored in—has reached as high as 104°F in Detroit, well above the seasonal norm of 80–82°F. These conditions are expected to persist, making it vital to stay alert for weather updates and heat advisories.
2. Hydration Is Non-Negotiable
Staying hydrated is one of the most effective ways to prevent heat-related illnesses. The Michigan Department of Health and Human Services (MDHHS) recommends drinking plenty of water and avoiding sugary or alcoholic beverages, which can worsen dehydration. Even if you don’t feel thirsty, keep sipping water throughout the day, especially if you are outdoors or physically active.
3. Seek Air Conditioning or Cooling Centers
Air conditioning is the best defense against extreme heat. If you don’t have access at home, spend time in public places like shopping malls, libraries, or designated cooling centers—many counties provide lists of these facilities during heat waves. Fans can be helpful, but only if the indoor temperature is below 90°F; above that, they may not prevent heat-related illness.
4. Limit Outdoor Activities and Avoid Peak Heat
Try to schedule outdoor activities for the early morning or late evening when temperatures are cooler. During the hottest parts of the day (typically 10 a.m. to 4 p.m.), stay indoors as much as possible. If you must be outside, take frequent breaks in the shade and avoid strenuous activity.
5. Dress for the Weather and Use Sunscreen
Wear lightweight, loose-fitting, and light-colored clothing to help your body stay cool. Sunscreen is essential, as sunburn can impair your body’s ability to cool itself and increase the risk of heat-related illnesses. Reapply sunscreen regularly, especially if you’re sweating or swimming.
6. Watch for Signs of Heat-Related Illness
Heat exhaustion and heat stroke are serious risks during extreme heat. Warning signs include heavy sweating, muscle cramps, weakness, dizziness, headache, nausea, vomiting, fainting, and extremely high body temperature (above 103°F). If you or someone else shows these symptoms, move to a cooler place, hydrate, and seek medical attention if necessary.
7. Check on Vulnerable Populations
Older adults, young children, and people with chronic health conditions are at increased risk during heat waves. Check in regularly on neighbors, relatives, and friends who may need help. Never leave children or pets in parked cars, even for a few minutes, as temperatures inside can rise rapidly and become deadly.
Conclusion
Michigan’s 2025 summer is shaping up to be one of the hottest in recent memory, with prolonged heat waves and high humidity pushing heat indices well above 100°F in many areas. By staying hydrated, seeking air conditioning, limiting outdoor activities, dressing appropriately, and watching for signs of heat-related illness, you can protect yourself and others from the dangers of extreme heat. Community support and awareness are key—reach out to those who may need extra help, and don’t hesitate to use local resources like cooling centers to stay safe this summer.
