A heat advisory is set to run across the eastern portion of South Florida from 11 a.m. to 6 p.m. June 23, with heat indices reaching 105 to 110 degrees. The stretch of extreme heat comes as wildfire smoke continues to degrade air quality in parts of Miami-Dade
By late morning, the thermometer won’t tell the whole story. The National Weather Service has issued a heat advisory across the eastern portion of South Florida for June 23, warning that heat indices could climb as high as 105 to 110 degrees.
The advisory runs from 11 a.m. to 6 p.m. June 23. It covers an area stretching from north of Fort Lauderdale to south of Homestead, including Fort Lauderdale, Homestead, and Miami.
For the rest of the week. the forecast keeps pointing back to the same daily reality: heat indices could hover in the 105 to 110 degree range every afternoon across the region. with the highest risk over urban areas. Probabilities of major heat risk in those cities are around 50%, according to the NWS.
Tomorrow’s events could add pressure to the clock. Extreme heat is expected to last into June 24, and it could affect fans traveling or gathering for the World Cup match scheduled in Miami Gardens on June 24, including those within the stadium.
The heat is arriving with only limited relief. The NWS says high temperatures will reach the 90s across “much of South Florida,” with only isolated to scattered storms expected to provide relief.
Outside temperatures aren’t the only concern for residents. Wildfire smoke continues to weigh on air quality in Miami-Dade County following a rash of wildfires that has worsened conditions since last week. Portions of the region are still being affected by smoke on June 23. with Doral. Sweetwater. and Westchester singled out as areas especially impacted.
Two sensors located near Sweetwater and Westchester showed air quality readings of 134 and 198 as of 8:40 a.m. on June 23. The Sweetwater-area reading was categorized as “unhealthy for sensitive groups. ” while the Westchester-area measurement was considered “unhealthy” overall—meaning everyone should take precautions by reducing outdoor activity and go inside to cleaner air if they have symptoms.
The wildfire conditions behind that smoke are tied to multiple fires burning across the county. The Quarry 2 Fire began on June 15 and is located near NW 137 Ave. and NW 41 St. As of June 21 at 1:26 p.m. it had grown to 19. 018 acres and was 97% contained. based on a map of active wildfires provided by the Florida Forest Service.
The Well Fire began on June 16, near NW 122 Ave. and NW 58 St. By June 22 at 7:15 p.m., it had burned 2,809 acres and was 85% contained.
In a third active area, the Corrections Fire is located south of 8th St. and west of Krome Ave. As of June 22 at 2:55 p.m., it had burned 330 acres and was 15% contained.
For residents deciding how to spend the day. the forecasts and sensor readings are converging into a narrow margin for error: heat indices could hit triple digits for hours. while smoke-related air quality guidance is already urging people to limit time outside and seek cleaner indoor air if they feel symptoms.
As June 23 moves through the heat advisory window, the combined pressure from temperature and air quality is likely to define how safe outdoor plans feel—whether it’s errands in the afternoon, a commute through urban areas, or preparations for the World Cup match set for June 24 in Miami Gardens.
