Miami ranks as the second-sweatiest city in America, according to a waterboy.com survey. Staying hydrated, particularly when working out outside, is critical. Pedro Vila wipes off sweat after a workout at Tropical Park.<\/p>\n

The National Weather Service issued another heat advisory Thursday for all of Miami-Dade, Broward and Palm Beach counties. It is the 11th heat advisory issued this month.<\/p>\n
And yes, it feels hotter than last year. By comparison, there were 11 heat advisories during the entire summer last year.<\/p>\n
The National Weather Service issues a heat advisory when the heat index \u2014 the \u201cfeels like\u201d temperature that combines air temperature and humidity \u2014 is expected to reach at least 105 degrees for two hours or more.<\/p>\n
Forecasters say it could feel as hot as 108 degrees today.<\/p>\n
When a heat warning is issued, even a Floridian who is \u201cused to\u201d the hot and humid summers is at risk of heat sickness.<\/p>\n
When humidity is high, it is harder for sweat to evaporate and keep a person cool. This amount of heat will affect anyone who doesn\u2019t drink plenty of water and find air-conditioned or shaded places to cool off.<\/p>\n
The hottest temperatures are expected in Homestead, where the high is forecast to reach 96 degrees. Miami is expected to reach 94 degrees.<\/p>\n
It\u2019s been hotter than average this week because South Florida has seen little rain, a forecaster with the National Weather Service\u2019s Miami office said.<\/p>\n
Miami has more than double the number of heat records this year than in June 2024, which is known as the hottest year ever. Heat is a silent killer. The Weather Service recorded 529 heat fatalities that year,<\/a> which almost certainly is an undercount.<\/p>\n What the NWS is calling a \u201cmajor\u201d heat risk is expected to continue into tomorrow.<\/p>\n Ashley Miznazi is a climate change reporter for the Miami Herald funded by the Lynn and Louis Wolfson II Family Foundation and MSC Cruises in partnership with Journalism Funding Partners.<\/p>\n This story was originally published July 16, 2026 at 9:25 AM.<\/p>\n
