If you’ve lived in the Big Guava for more than a week, you know the drill. One day you’re sweating through your shirt at a Rowdies game, and the next you’re digging through the garage for that one heavy coat you bought for a trip to North Carolina three years ago. Honestly, this week is basically the poster child for that Florida weather whiplash. We are looking at a massive temperature swing that starts with a literal freeze warning and ends with a day that’s almost shorts-and-sandals weather again.
Florida winters are weird. They don't just "arrive" and stay; they invade in short, aggressive bursts. This particular 5 day forecast for tampa florida is a rollercoaster ride from the mid-20s (if you’re a bit inland) back up to the mid-70s. It’s the kind of week where your car’s AC and heater are going to be fighting for their lives.
The Big Chill: Sunday and Monday’s Reality Check
Sunday is starting out a bit messy. If you looked outside this morning, it was mostly cloudy with a current temp sitting right around 55°F. But don't let that fool you. There’s a strong cold front sweeping through, and it’s bringing some guest stars: wind and rain. We’ve got a northwest wind kicking up at 22 mph, which is going to make that 69°F high feel a lot less like "paradise" and a lot more like "get inside."
The National Weather Service has already put out the alerts. We’re looking at a High Surf Advisory and a Cold Weather Advisory starting tonight. Why? Because the bottom is about to drop out.

Tonight, Sunday, January 18, the temperature is forecasted to plunge to a low of 39°F. Now, 39°F might not sound "Arctic" to someone from Chicago, but in Tampa, that’s a state of emergency for our tropical plants. If you have hibiscus or palms in pots, basically get them in the garage now.
Monday, January 19—Martin Luther King Jr. Day—is going to be a "bright but biting" kind of day. It’ll be perfectly sunny, which looks great through a window, but the high is only hitting 59°F. With a north wind at 9 mph, it’s going to stay crisp. The humidity is dropping to a bone-dry 39%, so expect some static electricity and chapped lips. Monday night repeats the 39°F low, so keep those blankets handy.
The Thaw: Tuesday and Wednesday’s Slow Climb
By Tuesday, January 20, the "Great Freeze of 2026" starts to lose its grip. We’re looking at a high of 64°F under partly sunny skies. It’s still cool, but manageable. The overnight low moves up slightly to 40°F. Honestly, Tuesday is probably the best day this week for a walk on the Riverwalk—you’ll need a light jacket, but you won't be shivering.

Then comes Wednesday, January 21. This is when the Florida we love finally remembers it’s a subtropical peninsula. The high jumps significantly to 75°F. That’s an 11-degree leap from the day before! Humidity starts to creep back up to 58%, and the wind shifts to the northeast. It’ll be a mix of clouds and sun, but the "sweater weather" is officially on its way out. The low on Wednesday night will be a much more comfortable 49°F.
Turning Point: Rain Returns on Thursday
Just when you think you’ve got it figured out, Thursday, January 22, throws a curveball. We’re holding onto the warmth with a high of 72°F, but the moisture is back in a big way. Humidity is spiking to 81%, and we’ve got "light rain" in the forecast. It’s not a washout—only about a 20% chance of precipitation—but it’ll feel muggy and grey compared to the crisp start of the week.
Quick Glance: The Numbers
| Day | High | Low | Condition |
|---|---|---|---|
| Sunday (Jan 18) | 69°F | 39°F | Mostly Cloudy/Breezy |

| Tuesday (Jan 20) | 64°F | 40°F | Partly Sunny |
| Wednesday (Jan 21) | 75°F | 49°F | Partly Sunny/Milder |
| Thursday (Jan 22) | 72°F | 58°F | Light Rain/Humid |
What Most People Get Wrong About Tampa Winters
A lot of folks move here and think "Florida winter" is a myth. Then they experience a night like tonight. The reason it feels so much colder here than the thermometer says is the humidity. Even when it’s 39°F, that damp air cuts right through a light windbreaker. Plus, our houses are built to vent heat out, not keep it in.

Another weird thing? The "Nature Coast" effect. While Tampa might stay at 39°F, areas just north of I-4, like Lutz or Land O' Lakes, often see actual freezing temps (32°F or lower). If you’re commuting from Pasco County into downtown Tampa this week, you might actually have to scrape frost off your windshield on Monday morning. Yes, in Florida.
Practical Steps for the Next 5 Days
First off, check your irrigation. If you have an automatic sprinkler system, turn it off. Pumping water onto your grass right before a 39°F night can actually cause more damage if the water freezes on the blades.
Secondly, pet safety is huge. If it’s too cold for you to stand outside in a t-shirt for ten minutes, it’s too cold for your dog to sleep outside. Bring 'em in.
Finally, plan your wardrobe in layers. Monday is a "heavy coat in the morning, light jacket by 2 PM" kind of day. By Wednesday, you’ll be back to just a hoodie.
Keep an eye on the wind gusts today, especially if you’re driving a high-profile vehicle on the Skyway Bridge. Those 22 mph northwest winds can be tricky over the water. Stay warm, keep the plants covered tonight, and remember that the 70s are coming back in just a few days.
