If you’re looking at the 10 day weather forecast jacksonville beach fl and thinking it’s all palm trees and tan lines right now, you’re in for a bit of a reality check. Florida winters are basically a mood ring. One minute you’re in shorts, and the next, you’re digging through your closet for that one heavy hoodie you forgot you owned.
Honestly, the current situation is pretty brisk. As of Friday, January 16, 2026, we’re looking at a daytime high of only 52°F. That might sound like a dream to someone in Minnesota, but with a low of 35°F tonight, it’s legit cold for the coast. The wind is currently coming off the northwest at about 13 mph, making that 37°F air feel more like 28°F. Yeah, that’s "see your breath" weather.
The 10-Day Rollercoaster
The weirdest part about this specific stretch is how fast the numbers jump around. Tomorrow, Saturday, January 17, is gonna be a total outlier. We’re jumping up to a high of 68°F. It’ll be cloudy, sure, but that’s a 16-degree swing in 24 hours. If you’re planning on being out by the Seawalk Pavilion, you’ve gotta layer up because that warmth doesn't stick.

By Sunday, the temperature crashes right back down to 52°F. We’re also looking at a 40% chance of light rain during the day, which usually makes the oceanfront feel even rawer. Monday and Tuesday keep that trend going with highs hovering around 51°F and 52°F. Basically, the early part of next week is going to be crisp, sunny, and very "un-Florida."
Beach and Surf Reality Check
Don’t plan on a swim. Seriously. The water temperature is sitting around 61°F, and with the air being what it is, hypothermia is a real conversation.

The surf isn't exactly firing either. For the next few days, wave heights are mostly in the 1-2 foot range. There was a Small Craft Advisory in effect recently because those northwest winds were gusting up to 35 knots, making the Intracoastal "very rough." It’s calming down slightly, but Sunday will likely see another spike in wind (up to 19 mph) as another front pushes through.
What to Actually Do
Since the 10 day weather forecast jacksonville beach fl is leaning more toward "indoor activity" than "beach day," you’ve got to pivot. The Beaches Green Market is still a go on Saturday morning (Jan 17) at Penman Park. It’s usually a bit more bearable since you’re tucked away from the direct salt spray of the Atlantic.

If you’re sticking around until next weekend, things start looking up. By Saturday, January 24, we’re hitting 73°F. That’s the "sweet spot" everyone expects when they move here. Just keep an eye on the rain chance, which climbs to 40% by that Sunday.
Why the Forecast Changes So Fast
Jacksonville Beach is in a weird spot geographically. We get these "back-door" cold fronts that slide down the coast from Georgia. It’s why one day can be 75°F and the next is 48°F. Most tourists get caught out because they see "Florida" and pack nothing but flip-flops.
If you’re here right now, you’ll notice the locals are all in puffer jackets. We aren't being dramatic; the humidity makes the cold "heavier." It gets into your bones in a way that dry cold just doesn't.
Actionable Next Steps
- Pack a Windbreaker: Even on the sunny days like Monday, that northwest wind at 8-14 mph will bite if you're standing on the pier.
- Check the Tides: If you're walking the dog, the low tide on Friday is at 1:23 PM. It’s the best time to hit the hard-packed sand before the water comes back in and pushes you into the soft stuff.
- Watch the UV: Even when it’s 52°F on Friday, the UV index is a 4. You can still get a "windburn" that’s actually a sunburn.
- Plan for Saturday: It's the warmest day of the week (68°F). If you have outdoor errands or want to see the 904 Pop-up later in the month, use the warm windows wisely.
