You've probably looked at your phone's weather app three times already today. If you’re planning a trip or just trying to survive the week in Pinellas County, that st pete beach forecast 10 days view can be a total roller coaster. One minute it's showing a perfect beach day, and the next, there’s a giant rain cloud emoji that ruins your sunset dinner plans at the Don CeSar.
Honestly, Florida weather is fickle. Especially in January.
Right now, we are looking at a classic mid-winter shift. As of today, January 13, 2026, the current temperature is hovering around 64°F. It’s a bit grey out there. Cloudy skies are dominating the scene, and there’s a light breeze coming off the Gulf from the north at about 7 mph. It’s not "swimming in your bikini" weather for most locals, but if you’re visiting from Ohio, it probably feels like a tropical paradise.
Breaking Down the St Pete Beach Forecast 10 Days
Let's get into the nitty-gritty of what the next week and a half actually looks like. We aren't just looking at one flat temperature; we're looking at a cold front that's about to shake things up.
Tomorrow, Wednesday, January 14, will stay fairly consistent with a high of 66°F. But keep an eye on the evening. The rain chance jumps to 45% as we head into Wednesday night. This is the precursor to a front that’s going to bring some real "Florida winter" vibes.
The Thursday Shift
Thursday is when the wind picks up. We’re talking gusts around 24 mph from the northwest. The high will hit 60°F early, but then it’s going to tumble. By Thursday night, we are looking at a low of 46°F. If you’re staying near the water, that wind is going to make it feel much colder.
A Sunny but Chilly Weekend
If you were hoping for a weekend scorcher, I’ve got some bad news and some good news. The good news? The sun is coming back. The bad news? It’s going to be crisp.
- Friday (Jan 16): Full sunshine, but the high is only 56°F. It’s a "hoodie on the beach" kind of day.
- Saturday (Jan 17): Things start to moderate. We’ll see 63°F with partly sunny skies.
- Sunday (Jan 18): Expect a high of 60°F with a stiff north wind.
It’s basically a gorgeous weekend for walking the Pass-a-Grille stretch, but maybe not for a dip in the Gulf unless you’ve got a thick wetsuit. Speaking of the water, the sea temperature is currently sitting around 68°F. That's actually warmer than the air right now!
Why the 10-Day Outlook Changes So Fast
People always ask why the st pete beach forecast 10 days out is so unreliable. It’s the Gulf of Mexico.
The Gulf acts like a giant heat engine. In the winter, cold air masses from Canada travel down the center of the US and hit that relatively warm water. This interaction creates unpredictable cloud cover and sudden wind shifts that global weather models sometimes struggle to pin down until about 48 hours before.
Looking into Next Week (Jan 19 - Jan 23)
By Monday, January 19, the sun stays out, but we remain in the upper 50s. It isn't until the end of next week—specifically Wednesday, January 21, and Thursday, January 22—that we start seeing the 60s return in a meaningful way.
By Friday, January 23, the humidity starts to creep back up. We’re forecasting a high of 67°F and a low of 65°F, which is a very narrow margin. That usually means one thing: fog or heavy cloud cover.
Survival Tips for a St. Pete January
Don't let a "chilly" forecast ruin your trip. You just have to pivot.
First, layering is the law. You might start the morning in a light jacket, switch to a t-shirt at 2:00 PM, and be back in a sweater by 6:00 PM. That's just the way it goes here.
Second, if the wind is coming from the North or Northwest, the beach is going to be brutal. Move inland. The shops on Central Avenue in downtown St. Pete are much more protected from the wind than the open shoreline of the beach.
Third, watch the UV index. Even when it's 56°F on Friday, the UV index is still hitting a 4. That’s enough to give you a sneaky sunburn because you don't feel the heat on your skin.
Actionable Next Steps for Your Trip
- Check the wind direction: If it's over 15 mph from the West, forget the beach umbrellas; they'll just fly away.
- Pack a windbreaker: It’s more important than a heavy coat. Blocking the Gulf breeze is 90% of the battle.
- Book indoor backups: If Wednesday night or Thursday morning look rainy, use that time for the Dali Museum or the Museum of Fine Arts.
- Monitor the "RealFeel": In Florida, a 60-degree day with 80% humidity feels very different than a 60-degree day with 30% humidity. Friday will be very dry and crisp, while next Thursday will feel "heavy" and damp.
The st pete beach forecast 10 days out shows a transition from a grey, mild week into a bright, chilly weekend, followed by a slow warm-up. Grab a coffee, find a sunny spot out of the wind, and enjoy the lack of mosquitoes—that's the real perk of a Florida January.

Keep an eye on local updates from the National Weather Service in Ruskin, as they often catch the small sea-breeze variations that the big national apps miss. Look for the "Small Craft Advisory" if you're planning on being on a boat, especially this Thursday when the northwest winds are expected to peak.
