Minnesota is about to swap comfortable summer weather for several days of dangerous heat and humidity. Afternoon temperatures will climb into the 90s, but the combination of heat and high humidity will make it feel even hotter, with heat index values soaring into the triple digits. Even after the sun goes down, temperatures will remain unusually warm overnight, offering little relief and allowing heat stress to build from one day to the next.

While Minnesota is no stranger to warm summer days, this stretch of weather is different because of the combination of high temperatures and tropical humidity. When humidity rises, your body's natural cooling system—sweating—becomes less effective. That's why the "feels like" temperature can be much higher than the actual air temperature.

The risk increases when overnight lows remain in the upper 60s and 70s, preventing our bodies from cooling down before the next hot day begins.

Whether you're working outside, heading to the lake, or simply running errands, following a few basic heat safety tips can go a long way in preventing heat exhaustion or heat stroke. Remember to drink plenty of water, wear lightweight clothing, apply sunscreen, and take frequent breaks in the shade or air conditioning. Small precautions can make a big difference during periods of extreme heat.

Our furry friends feel the effects of extreme heat, too. Make sure pets always have access to fresh, cool water and a shady place to rest. Walk dogs during the early morning or late evening when temperatures are cooler, and remember that hot pavement can burn their paws. Never leave a pet in a parked vehicle—even with the windows cracked—as temperatures inside can become life-threatening in just a matter of minutes.

Make sure to watch for heat-related illnesses. Heat exhaustion can cause heavy sweating, dizziness, nausea, weakness, and muscle cramps. Move to a cool place, drink water, and rest if these symptoms develop.

Heat stroke is a medical emergency. Symptoms can include confusion, hot, dry skin, or loss of consciousness. Call 911 immediately and begin cooling the person while waiting for help.
