Florida is under an extreme heat risk, the highest level on a four-tier scale, as temperatures surge across much of the state in early May 2026. Jacksonville reached 95 degrees on May 7, 11 degrees above normal and a record for its 155-year-old weather gauge. Forecasters expect “major” to “extreme” heat across South Florida, including Palm Beach, Broward, and Miami-Dade counties, over the weekend of May 9–10, with some inland locations and cities such as Orlando, Key West, and Vero Beach also projected to set record highs. Authorities are preparing for public health impacts, soaring energy demand, and potential power grid stress.
