AN UPCOMING weather alert remains in effect until 7 pm Tuesday as dangerous heat built up across South Florida, with comfortable temperatures climbing well above 100 degrees. A westerly wind kept the metropolitan area in the heat Tuesday, preventing ocean breezes from developing along the coast. Without that daily cooling influence, temperatures soared into the 90s Tuesday afternoon. Miami officially hit 100 degrees Tuesday afternoon, matching the highest temperature ever recorded in Miami. This graphic shows record temperatures in South Florida on Tuesday, August 18, 2026. CBS News Miami The CBS News Miami NEXT Weather team explained that weather records in Miami date back to the summer of 1895, and before Tuesday, the only other time Miami had reached 100 degrees was on July 21, 1942. That means today’s 100-degree reading ties the record that has stood for 84 years. Health officials urged families to take precautions during the hottest part of the day. Recommendations included staying hydrated, limiting time outdoors, taking frequent breaks in air conditioning, and checking on children, pets, and elderly neighbors who may be more vulnerable to the heat. Looking ahead, relief is in sight. The city of Miami hit 100 degrees on Tuesday, which is the first time since 1942. CBS News Miami The NEXT Weather Forecast expects a pattern change later this week that will allow afternoon storms to return to the forecast, including areas along the coast. Those storms should provide at least some relief from the afternoon heat, along with much-needed rain for the region. Until then, South Florida should prepare for another dangerously hot day, with little to prevent temperatures and humidity from rising toward the upper end of the scale Tuesday afternoon. In:
