Honestly, if you're checking the weather forecast for Flagler Beach Florida right now, you’re probably looking for that classic "Old Florida" sunshine. But January in Flagler is a bit of a wildcard. One minute you're sipping coffee at the Farmers Market in a t-shirt, and the next, you're digging through your trunk for a hoodie because the Atlantic breeze decided to get aggressive.
Today, Saturday, January 17, 2026, it’s actually pretty decent—if you don't mind a little cloud cover. We're looking at a current temperature of 66°F, though with the humidity sitting at 65%, it feels more like 69°F. It’s that weird Florida "winter" where the sun hits your skin and you feel warm, but the second you step into the shadow of the pier, you remember it’s January.

The Real Deal for Today and Tonight
We’ve got a high of 69°F on the books for this afternoon. The sky is keeping it "partly sunny," which basically means you’ll get those nice intervals of light for your beach photos before a cloud bank rolls through.
If you're out on the water, the wind is coming from the southeast at 7 mph, which is keeping things relatively calm for now. But don't get too comfortable. Tonight, the low is going to tank all the way down to 40°F. That is a massive 29-degree drop from the daytime high. If you’re planning on dinner at one of the spots along A1A, bring a real jacket. The "mostly cloudy" sky tonight won't be enough to trap any of that daytime heat.

Why the Forecast Here is Tricky
People often look at the weather forecast for Flagler Beach Florida and assume it's going to be exactly like Daytona or St. Augustine. It's not. Because Flagler is tucked where it is, the marine influence is huge.
- The Pier Effect: The water temperature at the Flagler Pier is hovering around 64°F right now. That’s actually a few degrees colder than the historical average of 70°F for mid-January.
- The "Feels Like" Factor: A 9 mph wind might not sound like much, but when it’s coming off the Atlantic in January, it cuts.
- The Cold Front Reality: There is a serious cold front moving in. While today is mild, the National Weather Service out of Jacksonville is already warning that Sunday and Monday nights will likely see temperatures drop below 40°F again. In fact, "The Sheltering Tree" over in Bunnell is prep-ing to reopen its cold-weather shelter because it’s going to get legit chilly.
Surf and Sand: Is it Worth Going In?
If you're a surfer, you probably already know. The surf forecast is calling for 0-1 ft and "glassy" conditions. Basically, it's a lake out there. Surf Captain is reporting "fair" conditions with 1-foot waves at best. If you do go in, you’re going to want at least a 3/2mm wetsuit.

For the rest of us just walking the cinnamon-colored sand? It’s perfect. The UV index is hitting a 3 today, so you aren't going to fry, but you still get that vitamin D.
What to Actually Pack
Forget the "Florida is always hot" myth. For a January trip to Flagler, your bag should look like a chaotic mix of seasons.
- Light layers for the 69°F afternoon.
- Heavy fleece or a windbreaker for the 40°F night.
- Closed-toe shoes. Flip-flops are great until the sun goes down and your toes go numb.
The weather forecast for Flagler Beach Florida tells us that the rain chance is low today—only about 5% during the day and 10% at night. You can leave the umbrella in the car. Just focus on staying warm once that sun dips below the horizon.
Looking Ahead
Tomorrow is where things get messy. We’re expecting a morning high of 59°F, but temperatures will actually fall throughout the day as a strong cold front pushes through. Winds are going to crank up to 15-25 mph from the West-Northwest, and the chance of rain jumps to 90%.
Basically, today is your "get outside" day.
If you’re sticking around, keep an eye on the local updates from FlaglerLive or the NWS Jacksonville briefings. This time of year, the forecast can shift in a heartbeat depending on how fast those fronts move across the peninsula. For now, enjoy the 66°F and the southeast breeze—it’s as good as it gets before the big chill hits tonight.
Next Steps for You:
Check the marine forecast if you're planning on taking a boat out tomorrow, as a Small Craft Advisory is likely with those 25 mph winds. Otherwise, make sure your outdoor plants are covered before that 40°F low hits tonight.
