Honestly, if you’re looking at the 10 day forecast stuart fl, you’re probably expecting that classic, postcard-perfect Florida sunshine. And look, usually, you’d be right. But right now? Things are getting a little weird on the Treasure Coast.
We’ve got a massive temperature swing hitting us that’s going to make your wardrobe choices feel like a high-stakes guessing game.
The Immediate Reality Check
Sunday, January 18, 2026, started out feeling like a typical tropical dream with a high of 78°F. But don't let that fool you. As I'm writing this, a strong cold front is basically kicking down the door. By tonight, the temperature is going to crater down to 43°F.
That’s a 35-degree drop.
One minute you’re in flip-flops at Bathtub Reef Beach, the next you’re digging through the garage for that one heavy hoodie you bought on vacation in Maine. The wind is currently coming out of the southwest at 20 mph, but it’s shifting. By tomorrow, Monday, January 19, we’re looking at a high of only 60°F. It’ll be sunny, sure, but with a 13 mph wind from the north, it’s going to feel "Florida frozen."
The 10-Day Outlook: A Rollercoaster in Prose
If you’re planning your week, here is how the 10 day forecast stuart fl is actually going to play out. Tuesday stays cool at 68°F and cloudy. If you’re a boater, Tuesday is kind of a mess anyway—the National Weather Service has a Small Craft Advisory in effect through Monday afternoon, and the chop on the Intracoastal is expected to be rough.
By Wednesday, we start the slow climb back to "normal." We’ll hit 72°F under mostly cloudy skies. Then, things get a bit soggy.
Thursday and Friday (January 22-23) both carry a 25% chance of light rain. It’s not a washout, but it’s that annoying kind of drizzle that ruins a hair day. Expect highs of 74°F both days. Interestingly, the surf is predicted to peak around Friday at 1 AM with waves hitting 8 feet, though the cross-onshore winds might make it a bit messy for the local surfers at the Stuart Public Beach.
Saturday, January 24, looks like the winner of the week. We’re talking 79°F and partly sunny. If you have outdoor plans, this is your window. Grab it.
Why January Weather is So Unpredictable Here
People think Florida is just "hot" and "less hot." In reality, Stuart sits in this transitional zone. We get these cold fronts that roll off the continent, clashing with the warm moisture of the Gulf Stream just a few miles offshore.
- Humidity: Currently sitting at a whopping 98% tonight, which is why the air feels so heavy even as it cools.
- The "Vortex" Effect: When those north winds hit 15-25 mph, the wind chill is a real thing, even in the 34994 zip code.
- Rain Types: We aren't in the summer pattern of "3 PM thunderstorms." January rain in Stuart is usually stratiform—grey, light, and persistent.
What to Do With This Information
Don't trust the clear skies on Monday morning. Even if the UV index is a 4 (which is moderate), that 43°F low is going to linger in the concrete.
If you're heading out to the St. Lucie Inlet, keep an eye on those north winds. They are forecasted to stay pretty stiff through Tuesday. For the gardeners, you probably don't need to worry about a hard freeze this week, but those 43°F nights are enough to stress out your more sensitive tropicals.
Basically, keep a jacket in the car. You’ll need it by 6 PM every single day this week.
Actionable Tips for the Week Ahead
- Boaters: Wait until Wednesday or Thursday for the swell to lay down; Sunday through Tuesday is going to be punishing on the water with seas up to 7-9 feet offshore.
- Beachgoers: Saturday is your best bet for a full tan-worthy day with a high of 79°F.
- Homeowners: Keep the irrigation off for a few days. With the humidity at 74-98% and light rain expected midweek, your lawn is doing just fine.
- Commuters: Monday morning will be clear but windy. Watch for debris on the Roosevelt Bridge if those gusts stay around 20 mph.
The 10 day forecast stuart fl shows a classic Florida winter tug-of-war. We finish the cycle next Tuesday, January 27, back in the mid-60s with more light rain. It’s a cycle of front, warm-up, rain, repeat. Welcome to January on the coast.

Check your tire pressure. These big temperature swings usually trigger those annoying "low pressure" sensors in your car. Better to fix it now than on the side of US-1 in the rain.
