You're looking at the forecast and seeing 80 degrees. Then you see 52. Welcome to winter in South Florida, where the "winter" part is basically a game of meteorological roulette. If you're checking the ft lauderdale weather 10 day forecast right now, you’re likely seeing a wild swing that would make a roller coaster jealous.
Honestly, people think Florida is just "hot" or "less hot." That’s a mistake. Especially this week.
The Wild Swing: From 80°F to 52°F in 24 Hours
Right now, Sunday, January 18, we are sitting in the "before" phase. It’s 80 degrees out there today. It feels like a tropical dream, but there’s a catch. Scattered thunderstorms are rolling in with a 35% chance of rain. If you’re at Las Olas or the beach, keep one eye on the sky.
But look at tonight. The low is plummeting to 52°F.
That is nearly a 30-degree drop in a single day. You’ve probably heard locals joke about "sweater weather," but when it hits 51°F tomorrow night (Monday, Jan 19), that’s not a joke. It’s a reality check. Tomorrow's high is only 67°F. For a tourist, that might feel like spring. For a Floridian, that is a full-blown arctic blast.
The Real 10-Day Outlook (Jan 18 - Jan 27)
Basically, the next week is a slow climb back to normalcy.
- Monday & Tuesday (Jan 19-20): Crisp and dry. Highs in the upper 60s to low 70s. North winds at 11-14 mph will keep things feeling even cooler.
- The Mid-Week "Wet" Phase: By Wednesday, January 21, the wind shifts to the east. This brings the moisture back. Expect light rain and highs creeping back into the mid-70s.
- The Weekend Recovery: By Saturday, January 24, we are back to 79°F. It’s the classic South Florida cycle: Front moves through, we freeze (relatively), then the humidity crawls back up.
Why the "Feels Like" Temperature Lies to You
Humidity is the silent killer of vacation plans. Today, the humidity is sitting at 78%. That’s why 80 degrees feels heavy. But by Tuesday, it drops to 60%.
When the humidity is low, the air doesn't hold heat. The moment the sun goes down behind the condos on A1A, the temperature crashes. You can be sweating at 2:00 PM and shivering by 6:00 PM.
Most travelers forget that Fort Lauderdale is a coastal city. That ocean breeze isn't always a "balmy breeze." On Monday, that 11 mph wind from the north is going to feel sharp. If you’re planning a boat tour or a visit to the Everglades, the wind chill on the water is going to be significantly lower than the "official" temperature.
The Ocean Temperature Myth
People see the ft lauderdale weather 10 day and think they can swim.
Can you? Sure. Should you? Kinda depends on your grit. The Atlantic water temp near Fort Lauderdale is hovering around 75°F right now. That sounds warm until you realize the air temperature on Monday is only 67°F. The "out of the water" experience is the part that gets you.

If you aren't used to 75-degree water, it’s going to feel refreshing. If you’re coming from the Northeast, it’s a bathtub. Just watch the "Rip Current" flags. Fronts like the one moving through today often kick up the surf and create hazardous swimming conditions.
Practical Next Steps for Your Trip
Don't let a cold front ruin the vibe. You just have to pivot.
- Layers are non-negotiable: Pack a light windbreaker or a hoodie. You will need it on Monday and Tuesday, especially if you're eating outdoors.
- Plan Indoor Activities for Monday: It’s going to be the "coldest" day of the stretch with a high of only 67°F. This is your day for the NSU Art Museum or shopping at Sawgrass Mills rather than the beach.
- Watch the UV Index: Even on the "cool" days like Tuesday (Jan 20), the UV index is a 4. That’s enough to give you a nasty burn because you don't "feel" the heat of the sun.
- Morning vs. Afternoon: If you’re golfing or playing tennis, Monday and Tuesday mornings will be in the low 50s. Wait until 11:00 AM for the sun to actually do its job.
The weather is going to be beautiful and sunny for the bulk of this 10-day window, just be ready for those two chilly nights at the start of the week.
