Miami, Florida – Temperatures will climb into the upper 80s and near 90°F by Thursday afternoon, bringing a summerlike stretch of heat across South Florida that will be felt quickly through the late week.
According to the National Weather Service and NOAA’s Climate Prediction Center, South Florida is in a 60 to 70 percent probability zone for above-normal temperatures from April 16 through April 20. A broad heat dome across the Southeast will limit rainfall and cloud development, allowing temperatures to trend several degrees above seasonal averages.
In Miami-Dade and Broward counties, highs are expected to reach 87 to 91°F between 1 p.m. and 5 p.m., with overnight lows holding in the low to mid-70s. Along the I-95 corridor from Miami through Fort Lauderdale to West Palm Beach, dry air and strong sunshine will contribute to drying vegetation despite higher humidity levels.
Fort Lauderdale and West Palm Beach will see highs in the upper 80s, while inland areas such as Kendall and Homestead may briefly touch 90°F during peak heating. Coastal sea breezes will offer brief relief but will not bring meaningful rainfall.
The precipitation outlook shows a 33 to 50 percent chance of below-normal rainfall, reinforcing dry conditions and increasing the potential for localized brush fires, especially in inland and grassy areas.
Residents should limit outdoor burning, stay hydrated, and avoid prolonged exposure during peak afternoon heat. Drivers should be mindful of vehicle heat buildup, especially in heavy traffic along major roadways.
The most consistent heat is expected April 18 through April 20, when temperatures hold near 90°F each afternoon. Additional advisories are possible as warm and dry conditions continue into early next week.
