Honestly, if you're looking at the 7 day forecast Naples specifically for Southwest Florida, you’re probably trying to figure out if you need to pack that extra hoodie or if it’s finally time to commit to the flip-flops full-time. Most people get Naples wrong. They think it’s just a "warmer version of the north," but in mid-January, it’s actually a complete atmospheric outlier.
While the rest of the country is currently battling a "super cold" winter with below-average temperatures—thanks to a lingering El Niño—Naples is sitting in this weirdly perfect pocket of 70-degree afternoons. But don't let the sunshine fool you. There's a nuance to the Florida winter that most tourists miss until they're shivering at an outdoor dinner on 5th Avenue South.
The Reality of the 7 Day Forecast Naples Florida
Right now, as of Sunday, January 18, 2026, we are looking at a classic South Florida winter stretch. If you look at the immediate numbers, it's a bit of a rollercoaster. Today, we’re seeing a high near 78°F with a low around 60°F. That 18-degree drop is what gets people. You're sweating at the Art Fest Naples Invitational at Fleischmann Park (which, by the way, is happening right now), and then by 6:00 PM, you’re looking for a fleece.

Here is the vibe for the next week:
- Early Week (Jan 19-20): Expect a slight dip. We're looking at highs around 73°F and lows hitting the lower 50s. It’s "Florida cold," meaning the locals will be in parkas and the visitors will still be in the pool.
- Mid-Week (Jan 21-22): The humidity starts to creep back. Highs will push back toward 78°F. Thursday night is the one to watch—there's a 20% chance of late-night showers as a weak front stalls over the Everglades.
- The Weekend (Jan 24-25): This is the "Goldilocks" zone. We're looking at crisp, sunny skies with highs of 80°F.
Basically, the 7 day forecast Naples is telling you to dress in layers. It’s not a suggestion; it’s a survival tactic for your social life.
What Most People Get Wrong About January Weather
People see "sunny" on a weather app and assume it’s beach weather. Is it? Kinda. The sea temperature right now is hovering around 68°F to 70°F. For a Floridian, that’s basically liquid ice. For someone from Michigan, it’s a tropical paradise.
The wind is the real factor. In January, we get these "gentle breezes" from the Northeast at about 8 to 14 mph. On paper, that sounds lovely. In reality, when you're sitting on the pier watching the sunset, that wind coming off the Gulf makes 70 degrees feel like 62.

Why the "Naples Winter" is Changing
There’s a lot of talk about the 2026 winter being "cooler than normal" across the southern tier. The Old Farmer’s Almanac and NOAA both pointed toward a damp, humid winter for Florida this year. While we haven't seen the "bitter cold" hitting the Ohio Valley, we are seeing more overcast days than usual.
Usually, January in Naples is one of the driest months. This year? Not so much. We’ve already had a few systems bring light rain and "mist" (as the Naples Municipal Airport weather station logged earlier this month). It hasn't ruined any golf games yet, but the grass is definitely greener than it usually is this time of year.
Survival Guide for the Current Forecast
If you're heading out to the Art Fest today or planning a boat trip later this week, here’s the inside track.
- The 10:00 AM Rule: Do not leave your house based on how it feels at 7:00 AM. It’s going to be 58 degrees when you wake up and 77 by lunch.
- UV is Still a Thing: Even when it’s 74 degrees and "mostly cloudy," the UV index is hitting a 3 or 4. You will get a "winter burn." It’s a real thing, and it looks ridiculous with a sweater.
- Humidity Spikes: Watch the dew point. When it hits 60°F+ (which it’s projected to do by Friday), the air gets that heavy, tropical feel. That’s when the mosquitos come out to play in the evening.
Actionable Advice for Your Week
Stop checking the "daily high" and start checking the "hourly wind speed." If you’re planning to be on the water near Gordon Pass or Marco Island, anything over 12 mph from the North is going to make for a choppy, chilly ride, regardless of how much sun is out.
If you’re a local, keep the citrus trees covered if the overnight forecast dips below 45°F—though looking at the 7 day forecast Naples, we should stay safely above that "danger zone" for the next week.
Next Step: Grab a light windbreaker and head to the beach around 5:15 PM. The sunset is at 6:00 PM sharp this week, and with the current cloud formations, the colors are going to be insane.
