South Florida residents should prepare for another day of oppressive heat Sunday with heat-index values expected between 105 and 109 degrees, local weather forecasters said.
What this means for residents
The combination of high humidity and mid- to upper-90s air temperatures will make conditions feel significantly hotter during peak afternoon hours. Forecasters warned there is no statewide heat advisory in place for much of the region at the moment, but the conditions remain dangerous and warrant precautions.
- Stay hydrated: Drink plenty of water throughout the day.
- Limit strenuous outdoor activity during peak heating around midafternoon.
- Check on vulnerable people and pets, especially the elderly and those with medical conditions.
- Wear light, breathable clothing and seek shaded or air-conditioned spaces when possible.
Local temperature readings Sunday morning ranged from the upper 70s to low 80s in coastal communities cited by regional broadcasters: Fort Pierce 80, Jupiter Farms 80 and Boynton Beach 82. Forecasters noted the air mass includes a plume of Saharan dust just offshore that will help keep the atmosphere drier and limit widespread rainfall.
"We don’t have a heat advisory in place. It’s something I will be keeping my eye on, but it is still going to be dangerously hot," a WPBF weather report said.
Forecast through the week
Forecasters expect the hot, humid pattern to persist into Monday and through the coming week. Feels-like temperatures are forecast to remain in the triple digits for several days, and residents were advised to plan accordingly.
| Day | Air temp | Feels-like |
|---|---|---|
| Sunday | Mid to upper 90s | 105–109 |
| Monday | Mid to upper 90s | Triple-digit heat indices expected |
| Tuesday–Friday | Mid-90s | Isolated afternoon storms; heat remains dominant |
While some models suggest limited shower coverage during peak heating, meteorologists expect only about 20% coverage of showers at the height of the day in this pattern, with Saharan dust suppressing widespread development.
Practical tips and local concerns
Public-health officials typically recommend avoiding prolonged outdoor exertion during the hottest hours and to look for cooling centers or air-conditioned public spaces if home cooling is not available. Pet owners should ensure animals have shade and water at all times.
I'll continue to monitor forecasts and local advisories and will update residents if heat advisories or other alerts are issued.
