If you’re sitting in Stuart right now looking at your thermometer, you’re probably wondering if someone swapped the Florida coast for the Carolinas overnight. Seriously. This morning, Friday, January 16, 2026, we’re seeing a current temperature of 49°F. For a town that usually brags about its "Sailfish Capital" sunshine, that northwest wind at 7 mph adds a bite that’ll make you reach for the heavy puffer jacket you usually leave in the back of the closet.
Honestly, the weather here is just weird right now. We’ve got this massive cold front pushing through the state, and it’s turning the Stuart 10 day forecast into a total guessing game for anyone trying to plan a weekend on the water.

The immediate chill: Bundle up tonight
Today is looking sunny with a high of 63°F, but don’t let the blue skies fool you. The humidity is sitting at 59%, and that UV index of 1 means you won’t be getting much warmth from the sun. Tonight is the real kicker. We’re looking at a low of 40°F under cloudy skies.
If you have sensitive plants or those decorative palms that aren’t quite "Florida hardy" yet, you might want to bring them in. While a hard freeze isn't expected this far south—unlike our friends up in Orlando who are dealing with record-breaking 25-degree projections—it’s still going to be one of the coldest nights we've had in years.
The Saturday bounce-back
Tomorrow, Saturday, January 17, is when things start to get interesting. The wind shifts to the northeast at 5 mph, and the high jumps significantly to 72°F.

- Morning: Still chilly, starting in the 57°F range.

- Chance of rain: It’s a low 20%, so you're probably safe for outdoor lunch plans.
Sunday’s wild humidity spike
By Sunday, the Stuart 10 day forecast throws us another curveball. We’re hitting a high of 74°F, but the humidity is going to climb to 71%. It’s going to feel thick.
Wait, it gets crazier. The wind is projected to kick up to 18 mph coming from the west. If you’re planning on being out on the St. Lucie River, keep an eye on the chop. There’s a 35% chance of rain during the day, which usually means those fast-moving Florida showers that ruin a car wash but don't last more than twenty minutes.
Looking ahead: The long-range outlook
Monday, January 19, brings us back down to reality. It’ll be sunny with a high of 59°F and a low of 44°F. Basically, the roller coaster is in full effect.
- Tuesday (Jan 20): Partly sunny, high of 64°F. Nice, crisp, North winds at 17 mph.
- Wednesday (Jan 21): Mostly cloudy, hitting 70°F.
- Thursday (Jan 22): This is our "wet" day. Light rain is expected with a 65% chance of precipitation. High of 74°F.
By the time we hit next weekend, the temperatures finally stabilize in the high 70s and even reach 80°F by Sunday, January 25.
What this means for your weekend
It’s easy to get caught off guard by these 30-degree swings. One day you're in a hoodie, the next you're thinking about the beach.
Historically, January is Stuart's coldest month, usually averaging a high of 73°F and a low of 62°F. This current stretch is well below those norms. Expert meteorologists across South Florida are noting that this specific cold mass is one of the most intense "polar pushes" we've seen since the Christmas 2022 event.
So, if you're headed out, layer up. The wind chill this morning was reportedly near 38°F at Witham Field. That's "stay inside and drink coffee" weather, not "go to the sandbar" weather.
Actionable insights for the next 72 hours:
- For Boaters: Sunday is going to be rough. With 18 mph western winds, the Atlantic and the Intracoastal will have some significant movement. Maybe stick to the dock.
- For Gardeners: Cover the tropicals tonight. 40°F is the danger zone for certain hibiscus and orchids.
- For Your Wardrobe: Keep the light jacket handy through Monday. Even when it hits 70°F, those north winds make it feel about five degrees cooler than the thermometer says.
Stay warm out there, Stuart. The 80-degree weather is coming back eventually, but for now, just enjoy the excuse to wear your favorite boots.
