Summertime is not the same all over the world. In the Northern Hemisphere, summer occurs in June, July, and August. In the Southern Hemisphere, it happens in December, January, and February. So if you are traveling to the United States in July, you should be aware that this is typically one of the hottest times of the year. Some popular vacation spots can easily reach over 100°F (or 37°C). This is perfect if you enjoy lounging on the beach, sitting by the pool, or lake activities.
Before you plan your trip, it's important to know what the weather will be in that locale. If you want to avoid the heat, many places on this list aren't for you, but if you love basking in the sun, these locations are perfect. Many states see an excess of sunshine and heat but one in particular sees more than most – Florida. After all, it is called the Sunshine State and sees anywhere from 230 to 250 days of sun every year. (It's not the only sunny state. Click here for the cities that get almost 6 hours of full sun a day on average.)
Methodology
To determine vacation spots that hit over 100 degrees, 24/7 Tempo reviewed data on heat index forecasts from the NOAA's National Centers for Environmental Prediction. Cities were ranked based on the average forecasted heat index maximum for July 19 to 21, 2024. Data was aggregated from points to cities using Voronoi tessellation and place boundaries from the U.S. Census Bureau's TIGER/Line program.
Only cities where at least 25% of the housing stock is vacant for seasonal, recreational, or occasional use – a proxy for vacation activity – with at least 5,000 residents were considered. Data on population and vacancy status is from the Census Bureau's American Community Survey and are five-year estimates for 2022.
