If you woke up this morning in Tampa and thought you’d stepped into a different zip code, you aren’t alone. One minute it’s 42°F and you’re hunting for that one heavy coat you own, and the next, the Florida sun is trying to convince you it’s actually July. Honestly, the tampa weather 15 day forecast looks like a fever dream. We are currently swinging between "Arctic blast" and "pool day" faster than most people can finish a Cuban sandwich.
The Immediate Chill and the Weekend Bounce
Right now, the northeast wind is cutting through the bay at about 4 mph, keeping the current temperature at a crisp 42°F. It’s clear tonight, which is basically a recipe for all the heat to escape into space.
But check this out. Saturday is going to be a total 180. We’re looking at a high of 72°F. That’s a 30-degree jump from where we’re sitting at the moment. You’ve probably noticed the humidity is hovering around 70% right now, but it’s going to drop as the sun takes over. If you’ve got outdoor plans for Saturday, keep them. It’s the sweet spot before things get weird again on Sunday.
Sunday, January 18, brings a bit of a reality check. A northwest wind is going to kick up to 17 mph. That's not just a breeze; that’s the kind of wind that knocks over your patio umbrella. We’re expecting light rain with a 40% chance of precipitation and a high that struggles to hit 59°F. Basically, Sunday is for staying inside, watching football, and wondering why you live in a place where the weather has such bad mood swings.

What’s Actually Happening Over the Next Two Weeks
Looking further out in the tampa weather 15 day forecast, we see a pattern that’s kinda typical for a La Niña transition year. We get these "reinforcing surges" of cold air.
- Monday & Tuesday (Jan 19-20): Highs stay in the low 60s. It’s sunny, but that 10 mph north wind will keep it feeling like you’re in Georgia.
- The Mid-Week Warmup: By Wednesday, January 21, the northeast wind shifts slightly and we climb back to 69°F.
- The Rain Event: Mark Thursday, January 22, on your calendar. There is a 70% chance of rain. It’s not just a sprinkle; it’s a full-on "rain" day with a high of 70°F and a low of 57°F.
Honestly, the variation is wild. By the time we hit the following weekend, January 24 and 25, we are looking at highs of 77°F and even 82°F. It’s basically a roller coaster. You go from 39°F on Monday morning to 82°F by the following Sunday. If you're visiting from up north, this probably sounds like paradise. If you're a local, it just means your sinuses are going to be absolutely miserable.
Humidity and the "Real Feel" Factor
Most people look at the numbers and think they know the story. They don't. In Tampa, the humidity is the main character. Even when it’s 62°F, if that humidity is at 41% like it's projected for next Tuesday, it feels refreshing. But when it spikes to 83% during the rain on Thursday, that 70°F is going to feel heavy and damp.

The UV index is staying relatively low, mostly around 3 or 4. You still need sunscreen if you're out at Sparkman Wharf or walking the Riverwalk, but you won't melt in ten minutes.
Pro Tips for Managing the Tampa Forecast
Stop trusting the "average" temperature. The average high for January in Tampa is usually around 69°F, but as we can see from the current data, we are rarely at the average. We are either way above it or way below it.

- Layer like a pro: You need a shell for the 17 mph winds on Sunday and a light hoodie for those 39°F mornings on Monday.
- Watch the Thursday rain: 70% is a high confidence number for Florida. Expect commute delays on the Howard Frankland.
- Prepare for the 80s: By the end of the 15-day window, specifically around January 25-26, the heat returns. Swap the boots back for flip-flops.
The weirdest part of this tampa weather 15 day forecast is the overnight lows. We’re seeing a range from 39°F to 66°F. That is a massive delta for your AC system to handle. If you’ve got sensitive plants, Monday night is your biggest danger zone. After that, we should stay well above the frost line as we head toward February.
Basically, keep your umbrella in the car and your sweater on the passenger seat. You're going to need both before this month is over.
Stay on top of the daily shifts by checking the dew point rather than just the temp—that's the real secret to knowing if you'll actually be comfortable outside. Also, keep an eye on those northwest winds on Sunday; they tend to make the bay water choppy, so if you're planning on taking the boat out, maybe wait for the calm winds of the following Saturday.
