You're standing on the sugar-white sand of 30A, looking out at the emerald water, and suddenly the wind shifts. One minute it's 65 degrees and sunny; the next, a "blue norther" whistles through the sea oats, and you’re scrambling for a hoodie. Honestly, the weather forecast for Santa Rosa Beach Florida is a bit of a trickster, especially during these mid-winter months.
If you're checking the apps today, Tuesday, January 13, 2026, you'll see a high of about 57°F. It’s crisp. It’s gorgeous. But tonight? We’re looking at a dip down to 39°F. That’s the real Florida Panhandle—the part the brochures don't always mention. You need to know the nuances because a 10-degree difference here feels much larger when the humidity and the Gulf breeze get involved.
The 48-Hour Breakdown
Tomorrow, Wednesday, January 14, brings a bit of a shift. We’re expecting a high near 58°F or 60°F, but don’t let the sun fool you early on. There’s a roughly 35% chance of light rain during the day. It’s not a washout, just enough to make the boardwalks a little slick.
By Thursday, the "real" winter hits. A cold front is pushing through, dropping the high to just 47°F. Yes, in Florida. The low will hover around 37°F.
- Tuesday (Today): Sunny and bright. High 57°F, Low 39°F.
- Wednesday: Cloudier with light showers possible. High 58°F, Low 40°F.
- Thursday: Clear skies but biting cold. High 47°F, Low 37°F.
If you’re planning on dinner at Grayton Beach or hitting the shops at Gulf Place, Thursday is definitely a "heavy jacket" night. The wind is projected to kick up to 20 mph from the northwest. That wind chill is no joke.

Why the Gulf is the Wildcard
People always ask: "Can I swim in January?"
The short answer is: only if you're very brave or wearing a thick wetsuit. Right now, the sea surface temperature at Santa Rosa Beach is hovering around 65°F. For context, most people find water comfortable at 78°F or higher. Even though 65°F sounds "manageable" on paper, the air-to-water transition in the winter breeze is enough to turn your skin blue in minutes.
The Gulf of Mexico acts like a giant heat battery. It keeps our coastal towns a few degrees warmer than places like Crestview or DeFuniak Springs just 30 miles inland. But it also fuels the fog. When warm, moist air moves over that cooler 65-degree water, "sea fog" rolls in like a thick blanket. It can go from a clear view of the horizon to zero visibility in twenty minutes.
Looking Toward the Weekend
If you’re hanging around for the weekend, things start to stabilize. Friday, January 16, sees a return to the 60s. We’re looking at a high of 60°F and a low of 40°F under partly sunny skies.

Saturday looks like the winner of the week.
A high of 59°F or 60°F with almost zero chance of rain.
Perfect for a bike ride down 30A.
- Morning (8 AM - 11 AM): Expect temperatures in the mid-40s. Layers are your best friend.
- Afternoon (1 PM - 4 PM): This is the sweet spot. The sun is strongest, and the UV index sits around a 3 (moderate), so you still need sunscreen even if it’s chilly.
- Evening (After 5:06 PM): The sun sets early this time of year. Once it’s down, the temperature drops fast. Expect it to hit 45°F by dinner time.
Long Range: What’s Coming Later in January?
Looking further out toward the end of the month, the weather forecast for Santa Rosa Beach Florida suggests a "stair-step" warming trend. By the week of January 19, we might see highs creeping back into the mid-60s.
However, the National Weather Service and long-range models like the Farmers' Almanac suggest that late January could bring more rain. There's a signal for a wetter-than-average pattern starting around January 22. If you're booking a trip for the last week of the month, maybe prioritize indoor activities like the boutiques in Seaside or a long lunch at Red Bar.
Humidity and the "Real Feel"
Humidity today is sitting at about 48%, which is quite dry for us. Usually, it's closer to 70% or 80%. When the humidity is low in the winter, the air feels "sharper." It’s a great time for photography because the sky is that deep, piercing blue, but it can be tough on your skin.
What Most People Get Wrong
The biggest misconception is that "Florida is always hot." Santa Rosa Beach is in the Northwest corner of the state. We’re closer to Atlanta than we are to Miami. We get real seasons here, just without the snow. Well, usually without the snow. Every few decades we get a dusting, but for this January, the only white stuff you'll see is the sand.
Practical Steps for Your Stay
If you’re here now, keep an eye on the wind direction. A South wind brings warmth and humidity; a North wind brings the "dry cold."
- Download a radar app: Weather can change block-by-block along 30A.
- Check the flags: Even if it’s sunny, the Gulf can be dangerous. Local fire departments (like South Walton Fire District) post flag conditions daily. Even on a beautiful 60-degree day, strong rip currents can be present.
- Book dinner early: Since sunset is around 5:05 PM, the "golden hour" happens early. If you want a view, aim for a 4:30 PM reservation.
Pack a mix of t-shirts and heavy fleeces. You will likely use both in the same 24-hour period. That is just the reality of the weather forecast for Santa Rosa Beach Florida in the winter. It’s unpredictable, occasionally chilly, but always better than being in a blizzard up north.
Prepare for a significant cool-down this Thursday by bringing outdoor furniture cushions inside or securing lightweight items, as gusts could hit 20-25 mph. For the best beach walking conditions this week, aim for the window between 1:00 PM and 3:30 PM on Friday and Saturday when the sun is at its peak and the wind subsides slightly.
