South florida is currently under a heat advisory as temperatures climb to dangerous levels. The heat index which combines temperature and humidity, is expected to reach up to 110 degrees in most metropolitan areas, according to the National Weather Service (NWS) in Miami.

The advisory covers all metro areas and portions of interior South Florida. Residents are advised to take precautions as the region experiences a decrease in rain chances and an increase in Saharan dust.

Current weather conditions and forecasts

High temperatures are forecasted to be in the mid-to-upper 90s this afternoon. The heat index, which indicates how hot it feels, is expected to reach 107 degrees in Miami and West Palm Beach, and 106 degrees in Fort Lauderdale.

The heat advisory is in effect until 7:00 p.m. today, with temperatures remaining high throughout the day. Skies have been sunny and hazy, allowing heat to build up. The Saharan dust is expected to continue into the upcoming work week, maintaining above-normal high temperatures.

Safety tips for extreme heat

The National Weather Service recommends several measures to stay safe during this heat wave. These include:

  • Hydrating before you feel thirsty
  • Wearing lightweight clothing
  • Taking breaks in the shade or in an air-conditioned building
  • Limiting strenuous outdoor activities especially between 10 a.m. and 5 p.m.

Fans may not be sufficient to combat the heat, so seeking air-conditioned environments is crucial. Residents are also advised to stay hydrated throughout the day.

Long-term heat trends and future outlook

South Florida has been experiencing a prolonged period of high temperatures. Miami has recorded 90 degrees or higher for 34 consecutive days marking the 5th longest streak on record since 1895. If the current forecast holds, this streak could extend to 41 days tying with the third-longest stretch since 2011.

The record for the longest streak of 90-degree days is 56 days set in 2026. While the heat is expected to persist, there is some relief on the horizon. The current pattern is forecasted to break down this weekend, allowing for more tropical moisture and higher rain chances to cool the region.

The National Hurricane Center is also monitoring the possibility of weak tropical development in the northeastern Gulf of Mexico or just off the southeastern coast this weekend. Heavy rain is the main threat for Florida, Georgia, and the Carolinas, with the next named storm being Bertha.
