Honestly, if you're looking at a weather report for Largo Florida right now, you’re probably seeing a number that looks great on paper but feels a little different when the Gulf breeze hits your face. Today is Saturday, January 17, 2026, and Largo is currently sitting at a crisp 56°F. It's nighttime. The sky is clear with some periodic clouds drifting through, and the humidity is a whopping 94%. That’s Florida for you. Even when it’s "cool," it’s damp.
What’s Happening Right Now in Largo?
The air is relatively still. We’ve got a light 3 mph wind coming out of the south. If you’re out for a late-night walk near Central Park, it’s that specific kind of Florida cold that bites a little because of the moisture. Earlier today was a different story. We hit a high of 76°F under sunny skies. Basically, it was a perfect chamber of commerce day.
But don’t get too comfortable. Tonight, we’re looking at a low of 50°F. That’s a 26-degree swing in one day. You’ve probably seen the tourists in shorts while the locals are digging out their North Face jackets. It’s a classic Pinellas County scene.

The Forecast for Today and Tonight

- UV Index: 4 (Still enough to get a burn if you're fair-skinned)
- Rain Chance: 0% during the day, but a tiny 7% chance of a stray drop tonight
Largo isn't like Miami. We’re tucked right there in the "elbow" of the peninsula, and we get these cold fronts that sweep down and make the palm trees shiver. Tomorrow is actually expected to be much cooler. Some reports are calling for a morning high around 65°F with temperatures dropping into the 40s by tomorrow night. That’s a "Florida Winter" in a nutshell—blink and the season changes.
Why the Weather Report for Largo Florida Often Surprises People
Most people think Florida equals tropical heat 24/7. Not quite. January is statistically our coldest month. While the average high is usually around 67°F, we see a lot of volatility. One day you’re at the pool, the next you’re worried about your tropical plants.

The humidity is the real kicker. At 94% humidity, like we have tonight, the air holds the cold against your skin. It’s a "wet cold." People from up north laugh at us when we complain about 50 degrees, but then they get here and realize that 50 degrees in Largo feels like 35 in Chicago because there's no escape from the dampness.
Packing for Largo in January
Basically, you need to think in layers. If you pack only shorts, you're going to end up buying an overpriced "I Heart Florida" hoodie at a gift shop. Trust me.

- Light Layers: Cotton tees are great for the afternoon sun.
- A Real Jacket: You need something that breaks the wind, especially if you head over to the beach.
- Jeans: Leave the linen pants for July.
- Sunscreen: Even with a UV index of 4, that Florida sun is deceptive.
The "Cold Snap" Rumors
There’s been some chatter in the local news about rare snow chances further north in the state this weekend. For Largo? Don't hold your breath for a snowman. While the Carolinas and even parts of North Florida might see some flakes, we’re looking at rain and wind. Sunday is expected to be breezy with a 70% to 80% chance of rain. Winds could gust between 20 to 30 mph coming from the northwest.
If you’re planning on doing anything outdoors tomorrow, you might want to move it to this evening. The transition from today's sunny 76°F to tomorrow's windy, rainy 65°F (dropping to 40°F) is going to be abrupt. It's the kind of weather that brings out the "sneaky" cold.
Actionable Tips for This Weekend
- Cover your plants: If you have sensitive succulents or tropicals, tonight's 50°F is fine, but Sunday night's predicted 40°F is pushing it.
- Check the tide: If you’re heading to the boat ramp, those 30 mph winds tomorrow will make the Intracoastal pretty choppy.
- Layer up for the morning: If you're heading to the Largo Southeast Park or the Saturday morning markets, start with a jacket you can shed by 11:00 AM.
The weather report for Largo Florida is essentially a lesson in flexibility. Enjoy the clear skies tonight while they last, because the "Big Chill" (by Florida standards) is rolling in tomorrow. Keep an eye on those northwest winds; they’re the ones that really bring the temperature down. Stay warm, or at least, stay dry.
Next Steps: Check your outdoor pipes if you’re in a particularly exposed area, as the wind chill on Sunday night might make things feel significantly colder than the actual air temp. Clear any loose patio furniture before the 30 mph gusts arrive tomorrow morning.
