These Are the Hottest Cities in America This Summer

If you think it's been a hot summer, then you're right. Sure, there are always pockets of exceptions, but for the most part, it's been a scorching summer around the world, including in North America. So, what are the hottest cities in America this summer, according to weather experts?

The experts at CNN have a new report out discussing the heat trends of 2024 and the hottest cities in America. They mention that the most extreme heat is in the cities, "because buildings, roads and sidewalks radiate more heat than grass and trees, in what's known as the urban heat island effect, which can add as much as 20 degrees Fahrenheit to urban temperatures." It's true that walking around America's biggest cities in the dead of summer can be really hot. CNN adds that, "All of the country's 50 most-populated cities have gotten hotter over the past half century, and all but three are experiencing more 'extremely hot' days above 95 degrees, according to a data analysis by the International Institute for Environment and Development, shared exclusively with CNN."

So, what are the hottest cities in the country this summer? Looking at the top cities with the highest rise in days 95°F or hotter this summer, the first is Las Vegas, Nevada. Vegas has been super hot this summer, counting 83 days at 95°F or hotter and each day in July above 105, according to CNN. The hottest day was 120. Sure, it's "dry heat," as they say, but it's still a lot of heat. San Antonio, Texas, comes right after Las Vegas, followed by Nashville, Tennessee. Jacksonville, Florida, and Atlanta, Georgia, round out the top five.

As for the cities that are the hottest in the country and keep getting hotter, the top three are all in Arizona. Phoenix, Mesa and Tucson have experienced the highest number of days of extreme heat, according to CNN. The CNN report also indicates that summers are getting longer, so the mild air is coming in earlier in the season and leaving later. I'm all for this, since I personally like mild Halloween weather. Who wants to get all dressed up in a costume when it's snowing outside?

If you find yourself in dangerously hot weather, remember to try to stay hydrated; stay in an air-conditioned place; wear lightweight, loose-fitting clothing; and just take it easy. Also, have an emergency kit on hand for any severe weather conditions.

Nobody likes dealing with severe weather. But, it's part of life. Depending on where you live in the United States, you might come up against hurricanes, tornados, severe thunderstorms, blizzards and more. I've certainly had my fair share of severe weather events. Probably my most vivid memory was being in an ice storm, which knocked power out for about a week where I lived, including during Christmas. It was freezing cold, so my family and I had to go to a hotel that was out of town. Needless to say, our Christmas plans were totally different that year. So, what are some severe weather safety tips that may safe your life?

Before we get to the main tips, let's get through some basics. Stay informed when a severe weather event is approaching. It's simple but important. You don't want to be caught off guard when bad weather strikes. The National Oceanic and Atmospheric Administration and National Weather Service both have information that they provide leading up to and during a severe weather event. So, make sure to get the latest information in the case of any weather emergency. Local meteorologists also have good information, but the main alerts come from the National Weather Service.

Another mistake some people make is not taking "watches" seriously. For example, you might see that there's a severe thunderstorm watch in your area and think, oh, it's just a watch, I can go out for a walk. Don't do it. "A watch is used when the risk of a hazardous weather or hydrologic event has increased significantly, but its occurrence, location or timing is still uncertain," the National Weather Service explains. We'll get more into the specifics of a watch, warning and advisory later in this story.

Let's get into some severe weather safety tips that may safe your life.

A weather advisory, watch and warning all need to be taken seriously. So, what do they mean? According to the National Weather Service, "a warning is issued when a hazardous weather or hydrologic event is occurring, imminent or likely." A watch is where "the risk of a hazardous weather or hydrologic event has increased significantly, but its occurrence, location or timing is still uncertain." Finally, an advisory means, "hazardous weather or hydrologic event is occurring, imminent or likely."

During a severe thunderstorm, and any severe weather event, the best thing to do is stay inside and sheltered. "The best defense against thunderstorms is to stay inside a sturdy building or shelter that can protect you from deadly lightning, large hail, damaging winds, flooding rain and tornadoes," the National Weather Service says. Also, you don't want to risk getting hit by lightning, like in the image below.

During a tornado, get underground if possible. If you don't have a basement, get to the lowest floor possible. Also, during a tornado, watch for flying and falling debris. The National Weather Service advises to "use pillows, blankets, coats, helmets, etc. to cover up and protect your head and body from flying debris."

Be prepared. Have a good emergency kit, both in your house and your car. For the car, "An emergency kit should include booster cables, shovel, tow rope, sand or cat litter, and a flashlight with extra batteries," the National Weather Service says. "Do not forget a first aid kit, non-perishable food, and blankets or sleeping bags."

This one my mom and dad always tell me to do. And, they're right. "Keep your gas tank near full to avoid ice in the tank and fuel line," the National Weather Service advises.

Heat can make for a severe weather event, too. So, dress appropriately when it gets really hot. "Lightweight, light-colored clothing reflects heat and sunlight, and helps your body maintain normal temperatures," the National Weather Service says. They add to guzzle lots of "water or non-alcoholic fluids."

Sometimes, you just have to leave ahead of the storm to be safe. In the case of a hurricane, the National Weather Service says to "leave immediately if ordered." They also say that if you are allowed to stay, to "take refuge in a small interior room, closet or hallway on the lowest level during the storm. Put as many walls between you and the outside as you can," and "stay away from windows, skylights and glass doors."

Weather isn't just about thunderstorms and tornados. Air quality is a big part of weather events these days, too. Be on the lookout for air quality alerts in your area. If you have respiratory issues, you should wear a mask when out and about in bad air quality. You should also say inside if the air quality is especially bad.

Even on a perfect weather day, if you're at the beach, there are risks. The NOAA states, "To stay safe, you need to stay aware of the weather, the ocean, tide, and what is going on around you." They add, "Storms, such as thunderstorms, tropical storms, and hurricanes far out at sea can create dangerous waves and currents at the beach, even on a sunny day!"
