So, you’re looking at the weather for Sarasota this weekend. Honestly, if you just glance at the little icon on your phone, you’re missing the actual story of what’s about to happen on the Gulf Coast. Saturday looks like a dream, but Sunday? Sunday is bringing a reality check that might catch you off guard if you’re planning on hitting the Lido Key sand or taking the boat out beyond the pass.
Basically, we’re looking at a classic Florida "split" weekend.
Saturday: The Calm Before the Front
Saturday, January 17, is going to be about as close to "chamber of commerce" weather as it gets. We are talking high-definition blue skies. The high is hitting exactly 74°F, which is basically the sweet spot for anything outdoors. You’ve got light winds coming out of the southeast at about 5 mph to start, eventually picking up to 9 mph.
It’s perfect. It’s dry. The humidity is sitting at a comfortable 47% during the day, so it won’t feel like you’re walking through a wet sponge.
If you’re heading to the Century of Cars Parade at St. Armands Circle or the Rockin’ Run and Roll 5K, you couldn’t ask for better conditions. It’s "light sweater in the morning, t-shirt by noon" weather. But don't let the sunshine fool you into staying out late without a plan; once the sun drops at 5:59 pm, the temperature is going to dive. We’re looking at a low of 49°F overnight.
Sunday: The Coastal Reality Check
Everything changes when you wake up Sunday. A cold front is sliding through, and it’s bringing a 50% to 58% chance of rain, mostly in the morning.
While Saturday was a gentle breeze, Sunday is going to feel aggressive. We’re expecting northwest winds to crank up to 20 to 25 mph, with some gusts even higher. If you were thinking about a beach day, maybe pivot to an indoor plan like the Sarasota National Stamp Expo at the Sahib Shrine Temple or the Pictures at an Exhibition concert at the Van Wezel.

The high only reaches 69°F before the "real" cold air starts dumping in. By Sunday night, it’s dropping to a chilly 38°F to 49°F depending on how far inland you are. That’s a massive swing.
What Boaters Need to Know
If you own a boat, Saturday is your only window. Even then, the National Weather Service is noting that conditions will start to deteriorate early Sunday morning.
- Saturday: Smooth seas, east winds shifting south. Great for the Intracoastal.
- Sunday: It gets ugly. We’re looking at Small Craft Advisory conditions. Northwest winds at 20-30 knots and seas building to 4-6 feet, with occasional 8-footers in the afternoon.
Basically, Sunday is a day to stay at the dock and double-check your lines.
Why the "Feel" Matters More Than the Temp
Most people see "69 degrees" for Sunday and think it’s still warm. It’s not. Not with a 25 mph wind coming off the water. That "RealFeel" is going to be significantly lower, especially with the 76% humidity spike that comes with the morning showers.
The front is sharp. One minute you’re enjoying a lukewarm coffee on the lanai, the next you’re hunting for that heavy flannel you haven't seen since last February. It’s the kind of weather change that catches tourists in shorts and leaves locals wearing North Face jackets.

Actionable Tips for This Weekend
Don't let the shift ruin your plans. Just adapt.
First, front-load your outdoor activities. If you want to walk the Ringling Bridge or do the Namaste at The Bay Yoga (9:00 am Saturday), do it then. Saturday is the undisputed winner for any activity involving hair stayin' in place or skin staying dry.
Second, prep your plants and pets for Sunday night. A drop into the 40s or high 30s isn't a hard freeze, but it's enough to shock tropical plants that have been enjoying a mild winter so far. Bring the sensitive potted ferns inside.
Lastly, if you're attending the Venice-Nokomis Rotary Fine Art & Craft Festival, Saturday is the day for the sun, but Sunday might actually be less crowded if you don't mind a little wind and the occasional sprinkle. Just dress in layers. Florida winters aren't about the cold; they're about the transition.
Keep an eye on the sky Sunday morning. Once that wind shifts to the northwest and starts howling, the "Sarasota Summer" feel is officially on hiatus for a few days.
