Jacksonville braces for hot weekend: Meteorologist Katie Garner shares forecast and safety tips

Stay cool, hydrate, and keep an eye on the tropics

Weekend weather: Hot and sunny ahead

JACKSONVILLE, Fla. – Hi, it’s Katie Garner, your News4JAX meteorologist with The Weather Authority. Let me walk you through what you can expect in Jacksonville, Northeast Florida, and South Georgia as we roll into the weekend.

Today, we’re starting out mild with temperatures in the 50s, 60s, and 70s — you’ll feel it especially if you’re out early in Jacksonville, St. Augustine, Brunswick, or Waycross. Temps are expected to climb quickly, hitting 86 degrees this afternoon under sunny skies.

The coastal areas are forecast to stay a little milder, around the 70s, while inland spots like Clay County could get closer to 90. Going into the weekend, Saturday should bring us 89 degrees with sun and clouds, and Sunday looks even warmer at 92 degrees.

Overnight, you’ll feel those lows dip into the mid-60s, so you can expect a solid cool-down once the sun goes down.

It’s going to be a beautiful stretch, but remember: this is above average heat, especially by Sunday and Monday. If you’re spending time outside—maybe working in the yard or heading to the beach—don’t forget the sunscreen and plenty of water!

Boater Skip Day: Safety first

If you’re one of the folks heading out for Boater Skip Day, listen up. You’ll see partly cloudy skies, highs that are talking 87 degrees by late morning and up to 92 by 3 p.m. Winds are expected to stay light, around 6 mph, with a few breezy gusts mixed in—nothing to worry about, but it could feel pretty nice out on the water.

My biggest tip: keep that cooler stocked with water. The combo of heat and sun while you’re boating can sneak up on you. Dehydration isn’t just a hassle, it can ruin your whole day out there. So keep drinking, be smart, and enjoy!

Tropical update: Watching the Atlantic

Let’s talk tropics for a second. We’re on day five of hurricane season, and so far, the Atlantic and The Gulf are both quiet—no active systems, and that’s just the way we like it.

There is some activity out in the Pacific, but at this point it isn’t expected to impact us. Of course, I’m always keeping an eye on any new developments, so I’ll have updates for you if anything changes.

Looking ahead: Good now, rain next week

The weekend is shaping up great for any outdoor plans, but looking ahead, we could see rain return during the week—likely just a single day with showers in the mid-80s. I’ll keep you posted on Exact Track 4D as we get closer.

Enjoy the weather, stay safe on the water, and if you catch any stunning sunrises or fun moments this weekend, send them to us through SnapJAX!
