Tens of millions of people are under heat alerts right now. Here’s what’s actually dangerous, who’s most at risk, and what genuinely helps.
If it feels like this summer has been one long heat warning, that’s because it largely has been. A dangerous heat wave peaked across the western United States in early August, with Extreme Heat Warnings covering Arizona, California, Nevada, and Utah, and temperatures pushing past 110 degrees Fahrenheit in some spots, 7 to 12 degrees above normal for the region. More than 40 million people have been under some form of heat alert this month alone, and at least 44 deaths were linked to July’s heat waves before August even started.
Is this actually unusual, or does every summer feel like this now?
Both things are true, which is part of why it’s confusing. Extreme heat events have become more frequent and more intense over the past decade, so “another heat wave” doesn’t land the way it used to, even though each one carries real risk. NOAA’s August outlook points to a hot month for much of the country, with the Southeast and southern Mid-Atlantic carrying better than 50% odds of above-normal heat, and the Plains and Rockies facing their own stretch of high pressure and limited rain. This isn’t confined to the U.S. either. Europe has been dealing with its own brutal summer, including Italy’s Po River dropping to historic lows during the country’s fourth heat wave of the season.

Who’s actually at the highest risk?
Outdoor workers, young children, older adults, and anyone managing a chronic health condition. That’s not a throwaway line, it’s the group that accounts for the overwhelming majority of heat-related emergency room visits every summer. If you fall into one of those categories, or you’re checking in on someone who does, this is the month to actually pay attention to heat advisories instead of scrolling past them.
What are the actual warning signs of heat stroke?
Confusion, a body temperature above 103 degrees, hot and dry or unusually flushed skin, a rapid pulse, and in more serious cases, loss of consciousness. This is a medical emergency, not a “drink some water and rest” situation. If you suspect heat stroke, call 911 immediately, move the person to a cool, shaded space, and apply cold, wet cloths or ice packs to the head, neck, armpits, and groin while help is on the way. Minutes matter here more than people tend to assume.
What actually helps day to day?
Fewer people know this than you’d expect, so it’s worth saying plainly: check the forecast before you plan outdoor time, not after you’re already outside. Sites like Heat.gov and apps like FEMA’s give real-time alerts rather than a vague sense that it’s “pretty hot today.” Hydrate before you’re thirsty, since thirst is already a lagging indicator. Reschedule strenuous outdoor work or exercise for early morning hours when temperatures are lowest. And if you don’t have reliable air conditioning, know where your nearest cooling center is before you need one, not during an emergency.
None of this is complicated advice. It’s also the advice that gets ignored most often, usually by people who’ve lived through enough summers to assume they know their own limits. The heat doesn’t care how many summers you’ve survived before this one.
