You’d think a place nicknamed "The Sunshine City" would be immune to the whole "winter" thing. Honestly, it usually is. But today, Sunday, January 18, 2026, the current weather in St Petersburg Florida is doing something a little bit weird. If you stepped outside this morning expecting a tan, you’ve probably already retreated back inside for a hoodie.
It’s gray. It’s windy. And it’s definitely not beach weather.
Right now, the mercury is sitting at a cool 54°F. But here’s the kicker: with a biting northwest wind ripping through at 27 mph, it actually feels like 48°F. That’s the kind of damp, Florida cold that gets into your bones because the humidity is still hanging high at 84%. Basically, it’s a "socks with sandals" kind of day for the locals.
The Cold Front Flip: How We Got Here
We started the day with a high of 72°F, which felt like the St. Pete we know and love. Then the front hit. The sky turned that specific shade of "Tampa Bay Gray," and the temperature began its steady tumble. We're looking at a 75% chance of light rain through the afternoon, so if you're planning on hitting the Pier or walking Beach Drive, maybe don't.
Or at least bring an umbrella you don't mind losing to a gust.

Those winds aren't messing around either. We're seeing gusts today up to 29 mph coming from the northwest. For anyone with a boat, there’s a Small Craft Advisory in effect. The bay is choppy, and the offshore seas are building up to 7 feet in some spots. It's a good day to stay on the dock and maybe grab a coffee at Black Crow instead.
What to Expect Tonight and Tomorrow
If you think this afternoon is chilly, wait until the sun goes down. The clouds are expected to clear out late tonight, which usually sounds like a good thing, right? Well, not in January.
Clear skies mean all that ground heat escapes. We are bottoming out at a low of 47°F tonight.
There’s a Cold Weather Advisory creeping in for the whole area. While the panhandle is actually seeing some dusting of snow (no, seriously, Okaloosa County got some flakes this morning), we aren't getting the white stuff here in Pinellas. We just get the shivering.

Monday morning is going to be a shock to the system. Most of the inland areas are under a Freeze Warning, but here in St. Pete, the water usually keeps us a couple of degrees safer. Still, you’ll want to cover your sensitive tropical plants tonight. Those hibiscus bushes won't be happy.
St. Petersburg Weather: By the Numbers Today
Forget the complicated charts. Here is the raw data for today, January 18, 2026:
- Current Temp: 54°F (Cloudy)
- RealFeel: 48°F
- Today's High/Low: 72°F / 47°F
- Wind Speed: 27-29 mph from the Northwest
- Precipitation: 75% chance of light rain during the day, dropping to 10% tonight
- UV Index: A very low 1 (No sunscreen needed for once)
Is This Normal for January?
Actually, yeah, kinda. January 18 is historically one of the coldest days of the year for us. While the average high is usually closer to 68°F, we often see these dramatic swings when a strong front pushes through from the Gulf.
Most visitors get it wrong. They think Florida is a perpetual sauna. But the "St. Pete Winter" is real, even if it only lasts for 48 hours at a time. The record low for January in this area is way down in the 20s, so 47°F isn't "record-breaking," but it’s enough to make the iguanas a little sluggish.

Actionable Advice for the Next 24 Hours
If you are living in or visiting St. Petersburg right now, here is the game plan. First, bring in the pets. If you’re cold, they’re cold.
Second, check your tires. These sudden 20-degree drops in temperature can trigger those annoying low-pressure sensors on your dashboard. Don't panic; it's just physics.
Third, if you have a pool heater, today is the day it earns its keep. Otherwise, maybe stick to the indoor museums. The Dali or the Museum of Fine Arts are perfect for a day when the current weather in St Petersburg Florida is more "London" than "Caribbean."
Expect things to start warming back up into the 60s by Tuesday, but for now, find your heaviest sweater and lean into the "winter" vibes. This is about as close to a blizzard as we get.
Stay warm, keep the plants covered, and watch out for those northwest gusts if you're driving over the Skyway. It's a wild one out there today.
