You’re probably thinking about palm trees and melting Mickey bars. Honestly, most people booking a trip to Central Florida just assume it’s always "shorts weather." But if you’re looking at a weather report Kissimmee Florida right now, specifically for Sunday, January 18, 2026, you might be in for a bit of a shock.
Florida weather is a moody beast.
Right now, as I’m writing this in the middle of the night, it’s a crisp 58°F outside. It's clear with some periodic clouds drifting by, and the humidity is sitting at a whopping 98%. Basically, it feels like you're breathing through a damp cloth. But here’s the kicker for today: we are looking at a massive 33-degree swing.
The Wild Rollercoaster of a Kissimmee Winter
Today’s forecast is a perfect example of why packing for Florida in January is a nightmare. We’re hitting a high of 70°F this afternoon, which is lovely. It’ll be partly sunny, perfect for a stroll around Old Town or hitting the parks. But don’t get too comfortable.
By tonight? It’s dropping to 37°F.
Yes, you read that right. 37 degrees in the "Sunshine State."
If you’re standing in line for a ride at 9:00 PM, you aren't going to want that souvenir t-shirt; you’re going to want a heavy hoodie and maybe some gloves. This isn't just "cool"—it’s legitimately cold. This is the stuff travel brochures don't mention because it doesn't sell hotel rooms.

Why the Wind Changes Everything Today
The wind is the real story today. Earlier, we had a light breeze from the south, but the daily forecast shows winds kicking up to 22 mph from the west. That’s enough to blow the hat right off your head while you're walking across the Disney Springs parking lot.
There’s also a 45% chance of rain during the day. It’s not a washout, but it’s that annoying "partly sunny with a side of showers" vibe.

What the Averages Won't Tell You
If you look up the typical weather report Kissimmee Florida for January, you’ll see averages like a high of 70°F and a low of 52°F. Those numbers are liars. They are the "average," sure, but the reality is a series of cold fronts that crash through the state, followed by days of glorious, fake-spring warmth.
- The Humid Subtropical Trap: Even when it’s 70°F, the humidity (averaging 77% today) makes the air feel heavier.
- The UV Sneak Attack: Even on a "cool" day with a UV index of 2, that Florida sun is stronger than you think. You’ll still see tourists with lobster-red faces because they thought the clouds were a shield.
- The Wind Chill Factor: When those 22 mph winds hit that 37°F low tonight, it’s going to feel significantly colder than the thermometer says.
Surviving the Kissimmee Elements
If you're heading out today, you've got to play the layers game. It’s the only way to survive. Start with a light base, add a fleece, and keep a windbreaker in your bag. You’ll be peeling things off by noon and frantically putting them back on by 6:00 PM.
Also, a quick word on the theme parks: when the temps dip this low, some of the water-based attractions or water parks like Typhoon Lagoon or Volcano Bay might actually shut down. They usually pull the plug if it doesn't hit the mid-60s. Check the apps before you head out so you don't end up staring at a closed gate with your swimsuit under your jeans.
Actionable Insights for Today:
- Dress in three layers: A t-shirt, a warm sweater, and a windproof outer shell.
- Pack the poncho: 45% rain chance means you'll likely see a sprinkle; don't pay $20 for a plastic bag at the park gates.
- Hydrate despite the cold: You don't feel thirsty when it's 58°F, but the Florida humidity still saps your fluids.
- Check park hours: Some outdoor shows might be altered if the wind gusts stay high.
The bottom line? Kissimmee is beautiful, but it's unpredictable. Enjoy that 70-degree sun while it lasts this afternoon, because that 37-degree night is coming for you.
