Summer in Texas is no joke. But honestly, there are very few times of year that we actually get a break from breaking a sweat. So as you might expect, a few Texas cities topped the list of the country’s sweatiest cities.
A new ranking by hydration packet brand WaterBoy used 30 years of NOAA climate data to rank 80 U.S. cities on heat index, average temperature, dew point and relative humidity, building a Hydration Demand Score. Translation: they built a sweat scoreboard.
Among the top three sweatiest cities in the country were West Palm Beach, Miami and Fort Myers — all in the state of Florida. In fact, four of the top five cities were in the Sunshine State, with Honolulu breaking the streak in fourth place. Eight of the top 10 overall were in Florida, which doesn’t come as much of a shock. However, multiple Texas cities broke the top 15 — Houston at No. 9, San Antonio in 11th place and Dallas-Fort Worth at No. 14.
But those are the annual numbers. When you look at the same map during the summer, Houston jumps to fourth place, Dallas-Fort Worth climbs to No. 9 and San Antonio breaks the top 10. Understandably, things start to cool down in the fall, winter and spring — although, that’s not by much, as San Antonio recorded its hottest February day (93 degrees) in 30 years this February. Meanwhile, the city was among the hottest places on Earth back in May 2025.
Suffice to say, our notoriety is well-earned.
The ranking also gave each city an archetype. San Antonio was dubbed a seasonal surge city with hydration needs peaking in August. According to the ranking, your body can’t even fully reset from a workout overnight as temperatures in the Alamo City remain above 80 degrees. Meanwhile, Houston was both a seasonal surge city and a humidity trap, meaning the mugginess amplifies the heat beyond just temperature. July is the peak month in H-Town and the seasonal surge city of Dallas-Fort Worth.
By the way, the least sweaty city in the country is Spokane, Washington, and we’re not jealous at all…
