So, you're looking at the naples florida weather 30 day forecast and wondering if you should pack that heavy sweater or just stick to linen. Honestly? You probably need both. Naples is kind of a wild card in January and February. One minute you’re sipping an iced coffee on 5th Avenue South in 75-degree sunshine, and the next, a cold front dips down from the Panhandle and you’re suddenly hunting for a puffer jacket because it’s 46°F.
Right now, we are sitting in the middle of a weak La Niña year. If you follow the NOAA Climate Prediction Center, you know that usually means Florida stays warmer and drier than average. But "average" is a funny word. It doesn't account for the weirdly specific cold snaps that happen right about now.
The Reality of the Next 30 Days
Basically, if you're coming down between now and mid-February, expect a rollercoaster. For instance, today, Sunday, January 18, we’ve got some light rain and a high of 74°F. Sounds great, right? But tonight the floor drops out, and we’re looking at a low of 46°F with a 22 mph wind from the west. That’s enough to make the palm trees look like they’re struggling.

Tomorrow, Monday, January 19, is going to be a "bright but bitey" kind of day. We’re talking full-blown sun, but the high won’t even crack 62°F. If you’re at the beach, that wind coming off the Gulf is going to feel like a slap.
Here is what the trend looks like for the rest of the month:
- Late January: We see a steady climb back into the low 70s. By January 23rd, we should hit 75°F again.
- The Humidity Factor: Don't let the "dry season" label fool you. Humidity is hovering around 80-90% most mornings. It makes the 60s feel damp and the 70s feel like a warm hug.
- Early February: History tells us February is actually one of the most volatile months. The Almanac is calling for periods of heavy rain in the first two weeks of February 2026, though temperatures should stay mild, averaging around 62°F overall.
What Most People Get Wrong About Naples Winters
The biggest mistake? Thinking the Gulf of Mexico is a giant hot tub year-round. It’s not. The sea temperature right now is sitting at about 68°F to 70°F. If you're from Michigan, you’ll think it’s glorious. If you’ve lived in Florida for more than a year, you won't touch that water without a wetsuit until May.

Another thing is the "Sun Tax." Even when it's 65°F, that Florida sun is intense. The UV index is still hitting a 4 or 5 most days. You can absolutely get a sunburn while shivering in a North Face vest.
Why This Forecast Matters for Your Trip
If you’re a golfer, this naples florida weather 30 day forecast is actually your best friend. Those 65-degree days with 45% humidity (like we're seeing on January 19th) are peak conditions. You won't sweat through your polo by the third hole. Just watch the wind—northeast gusts can get up to 16 mph, which will definitely mess with your backswing.
For the beach-goers, stick to the afternoons. The mornings are misty and cool, but once that sun hits its peak around 2:00 PM, the sand holds the heat well.

Actionable Next Steps for Your Naples Visit
- Pack "The Naples Layer": You need a light windbreaker or a denim jacket. Seriously. The transition from a 75°F sunny afternoon to a 55°F breezy evening happens in about twenty minutes once the sun goes down.
- Check the "Feels Like": Always look at the wind speed. A 72-degree day with a 15 mph wind off the water feels like 64.
- Book Indoor Backups for Early Feb: Since we're expecting more rain than usual in early February 2026 due to this shifting La Niña pattern, have a list of indoor spots ready. The Baker Museum or the shops at Waterside are solid bets for when those "heavy rain" periods hit.
- Watch for the Freeze: While rare, we do have a "Florida Freeze" warning reaching southward right now. If you’re staying in a place with a lanai or tropical plants, make sure the sensitive stuff is covered if the forecast dips toward that 40-degree mark.
Don't let a few cool days ruin the vibe. Even on its "coldest" day, Naples beats a snowstorm in Chicago every single time. Just bring a hoodie and keep an eye on those west winds.
