Heat, humidity set stage for pop-up storms across metro Jacksonville

Jacksonville area braces for mid-90s heat and afternoon storms

JACKSONVILLE, Fla. – Jacksonville and its coastal neighbors are in for a hot one, with high temperatures set to soar into the mid-90s today.

Early morning conditions are starting out mild and calm, around 75 to 80 degrees, depending on whether you’re in St. Augustine, Mayport, or at the airport.

But don’t get too comfortable—as the day unfolds, that familiar Florida humidity is going to ramp up quickly.

It’s the kind of day where feels-like temperatures could push near or even over 100 degrees.

The combination of strong Gulf and Atlantic sea breezes moving inland is expected to deliver the classic recipe for afternoon thunderstorms.

For those heading out early, skies are predicted to stay clear for now, so morning plans should be safe from any major weather surprises.

Timing and areas most impacted

If you have outdoor activities scheduled, pay close attention to the clock. The Weather Authority expects the most active storm window to be between 3 p.m. and 9 p.m.

During this period, pop-up storms are likely across the metro area—including Jacksonville, Orange Park, and Mayport—as well as some inland towns.

While these storms are forecast to be non-severe, they may cause brief downpours or localized disruptions in your plans.

So, keep an eye on the sky this afternoon, and if you can safely capture dramatic weather scenes, share them with your neighbors on SnapJAX.

Beach and outdoor safety

If hitting the beach is in your plans, there’s good news from the Exact Track 4D: rainfall totals over the next couple of days are expected to be on the lower side, making for favorable beach conditions.

Still, the UV index will be very high—don’t forget that sunscreen and remember to stay hydrated, even if the skies look clear.

It’s possible you’ll have to dodge a shower or two, especially as pop-up storms can strike quickly.

But for the most part, lower rain chances mean you can enjoy the sunshine—just with a little extra caution.

Looking ahead

More details on the seven-day outlook, including any shifts in storm activity or temperatures, can be found in the latest updates from News4JAX and The Weather Authority team.

For now, stay weather-aware this afternoon and check the radar before making or changing outdoor plans.
