MIAMI —  Extreme heat is arriving earlier in the year, underscoring the urgent need for individuals and communities to be fully prepared.  In March 2026, a major heat wave broke records across the western United States, with some areas experiencing their earliest-ever 100°F days.  After one of the warmest years globally, forecasters now expect above-average temperatures across much of the country this summer.

“Extreme heat is the leading cause of weather-related deaths in the United States, yet too many people underestimate the risk,” saidKrista Coletti, Regional Executive for the American Red Cross South Florida Region.  “Nearly half of adults don’t believe a heat wave will harm them, and most aren’t very concerned about heat-related illness. Here in South Florida, it’s important to understand the risks of extreme heat and take steps now to be prepared.”

PLAN AHEAD To be ready for extreme heat, think about how you’ll stay cool. If you have air conditioning, make sure it’s working properly. If you don’t have air conditioning, think about where you’ll go to cool off, how you’ll get there and what you’ll take with you.

In an emergency it’s critical to act fast, so learn the signs of heat illness and what to do. Talk to your doctor about how you can stay healthy. Make sure you have supplies to keep medication cool and equipment charged, especially during a power outage. When a heat wave and a power outage happen at the same time, it can be even more dangerous. Visit here to learn what steps to take if the power goes out.

If you’re an athlete or you work outdoors, think about how you can alter your schedule to avoid the hottest times of the day. Consider how you’ll stay hydrated and find a cool place to take breaks. Don’t forget your furry friends and make sure pets have access to fresh water and shade.

CHECK ON OTHERS Once you’re ready for the heat, connect with loved ones and neighbors to see if they need help. Make a list of who you’ll check on and help them make a plan so they know what do. Have them sign up for free emergency alerts from their local government.
