A heat advisory is in effect across parts of South Florida from 11 a.m. to 7 p.m. Saturday, as dangerously hot and humid conditions are expected to push the heat index into the triple digits, the National Weather Service and local meteorologists said.
Actual air temperatures are forecast to remain in the upper 80s to low 90s, but high humidity will make conditions feel much hotter. Forecasters warned some communities could experience a heat index near 110 degrees, increasing the risk of heat-related illness for people spending time outdoors.
What residents should do
Local 10 meteorologist Jennifer Collins urged people to take common-sense precautions if they must be outside during the advisory period. Her recommendations align with guidance from the National Weather Service and public health authorities.
“Another hot one for today, really one of those days we’re in the middle of summer now. You really got to think heat safety out there, especially if you’re spending a lot of time outside for today.”
- Stay hydrated — drink water often, even if you do not feel thirsty.
- Take frequent breaks in the shade or in air-conditioned spaces.
- Limit strenuous outdoor activity during midday and afternoon hours.
- Check on elderly relatives, infants and people with chronic illnesses.
Early conditions and short-term forecast
Saturday began with more cloud cover than recent mornings after overnight rain helped bring slightly cooler readings to some spots. Early morning temperatures were reported in the low to mid-80s, including readings around 85 in Miami and 84 in Homestead, according to Local 10’s reporting on morning observations.
Despite the cloud cover along the Miami-Dade and Broward coasts, forecasters said humidity will remain high through the advisory period. Rain chances are expected to stay relatively low for most areas during the hottest part of the day.
| Metric | Expected |
|---|---|
| Air temperature | Upper 80s to low 90s |
| Heat index (feels-like) | Up to ~110°F in spots |
| Advisory window | 11 a.m. to 7 p.m. Saturday |
Officials and meteorologists recommend following forecasts closely through the afternoon. People who plan to work outdoors, attend events or exercise outside should adjust plans to reduce heat exposure and avoid heat exhaustion and heat stroke.
Track local updates from the National Weather Service and Local 10’s Weather Authority team for any changes to the advisory or spotty storm development later in the day.
