As of 4:53 a.m. EDT on Wednesday, July 8, 2026, Jacksonville was mostly clear, muggy and already feeling sticky with temperatures near 79°F at the KNIP observation site. A Heat Advisory covers much of northeast Florida and southeast Georgia on Wednesday, with forecasters calling for highs in the mid to upper 90s and heat-index readings pushing into the low 100s. Officials urge people to skip strenuous outdoor activity during the afternoon peak and keep water close for children, pets and older adults.
Heat Advisory and Peak Heat
According to NWS Jacksonville, the advisory is in effect from roughly 11 a.m. to 7 p.m. and warns of heat-index values between 106°F and 111°F across parts of northeast Florida and southeast Georgia. Inland highs should top out near 97°F with southwest winds of 6 to 12 mph and gusts up to 16 mph. With overnight lows stuck in the upper 70s, heat stress may linger into the evening for anyone without air conditioning.
Where to Cool Off
Jacksonville's "Stay Cool Jax" program keeps a running list of libraries, community centers, pools and designated emergency cooling centers, and it explains when free JTA rides to those spots kick in. Check Stay Cool Jax for locations and activation rules before heading out. If you have vulnerable neighbors or relatives, this is a good day to check on them and make a simple afternoon plan.
Beach Safety and Evening Storm Chance
Coastal spots should start the day sunny, but there is a Moderate rip-current risk with generally low surf of 1 to 2 feet, so it is not a bad idea to stay cautious at the shoreline. The forecast also calls for a slight, roughly 20 to 30 percent, chance of afternoon showers and isolated thunderstorms after 3 p.m., mainly inland. Any storm could bring brief heavy rain, frequent lightning and gusty, erratic winds. Boaters and beachgoers should keep an eye on the sky and head inland if storms start to build, according to NWS Jacksonville.
Through the Weekend
Upper-level ridging keeps dangerous heat in place through Thursday and Friday, with additional Heat Advisory potential later this week. Convective coverage is expected to ramp up Sunday into early next week as a front approaches.
