You're looking at the 10 day forecast naples and seeing a bunch of sun icons or maybe a few rain clouds. Honestly, it’s easy to just glance at those numbers and think you've got the week figured out. But if you’re actually planning to be on the ground—whether you’re hitting the cobblestones in Italy or the white sands in Florida—those little icons usually hide the real story.
Weather in both "Naples" locations is notoriously fickle this time of year.
Right now, as of January 14, 2026, the two cities are living in completely different worlds. One is shivering through a classic Mediterranean winter, while the other is flirting with t-shirt weather but bracing for a weird cold snap. Let's break down what's actually happening over the next ten days so you don't end up underdressed or stuck in a downpour.
Naples, Italy: The Mediterranean Reality Check
If you're looking at the 10 day forecast naples for the Italian side, don't expect a postcard. It’s January. It’s moody.
Today, Wednesday, it’s a respectable 58°F with some sun, but things are about to get grey. For the next several days, from Thursday through Saturday, the sky is basically going to be a giant wet blanket. We’re looking at highs around 59°F to 62°F. It sounds mild, sure. But the humidity is hovering near 75%, and that "damp cold" in Naples hits different. It gets into your bones.

The Sunday Shift
Watch out for Sunday, January 18. The models are showing a massive spike in precipitation. We’re talking an 85% chance of rain by nightfall. If you had plans to walk the Lungomare or hike up to Castel Sant'Elmo, you might want to pivot to the National Archaeological Museum instead.
The start of next week (January 19-21) keeps that trend going with light rain and "brisk" winds coming off the Tyrrhenian Sea. Temperatures will dip back into the mid-50s. Basically, if you aren't packing a solid waterproof shell and a scarf, you’re going to be miserable. Locals in the Quartieri Spagnoli don't mess around with this weather—they’re already in their heavy wool coats.
Naples, Florida: The Sunshine State’s Winter Identity Crisis
Across the pond, the 10 day forecast naples for Florida is a total rollercoaster.
Today started out cloudy and humid (93% humidity!), hitting a high of 73°F. But here is the kicker: a front is moving in. Tomorrow, Thursday, January 15, the wind is going to kick up to 22 mph. That’s not a breeze; that’s "hold onto your hat" territory.

The Deep Freeze (Florida Style)
Friday and Saturday are going to be gorgeous but shockingly cold for the locals. We’re looking at overnight lows of 41°F and 42°F. For a city that lives in flip-flops, that is a legitimate emergency.
- Friday, Jan 16: Sunny, but the high only hits 63°F.
- Saturday, Jan 17: Back up to 70°F, which is the sweet spot.
- Early Next Week: The heat returns. By Thursday and Friday (Jan 22-23), we’re looking at 76°F and 78°F.
It’s basically two seasons packed into ten days. You’ll need a parka at 6:00 AM and a swimsuit by 2:00 PM.
What the "Averages" Usually Miss
Most people check the 10 day forecast naples and see an average high of 55°F in Italy and think, "I can handle that." What they miss is the wind chill. In Italy, the wind speed is averaging 12-14 mph over the next week. That turns a 55°F day into a "my face is numb" day real fast.
In Florida, the "average" is 74°F, but the spread is wild. When the dew point drops on Friday, it’s going to feel incredibly dry. Great for your hair, maybe not so great for your skin.

Actionable Tips for the Next 10 Days
Don't just trust the app. Here is how to actually survive the current 10 day forecast naples depending on where you are:
For the Italy Travelers:
- Layers are your God: Wear a base layer. The stone buildings in Naples don't hold heat well, so even indoors, you might feel the chill.
- Rain-Proof Your Feet: The streets in the historic center get incredibly slick when wet. Wear shoes with actual grip, not flat-soled sneakers.
- The "Sunday Pivot": Save your indoor activities (museums, pizza making classes) for Jan 18th and 19th when the rain is at its peak.
For the Florida Snowbirds:
- The 40-Degree Rule: If you’re visiting from the North, 42°F sounds like spring. In the Florida humidity, it feels like 30°F. Bring a real jacket for those Friday/Saturday mornings.
- Wind Awareness: Thursday is a wash for the beach. 22 mph winds mean sand in your eyes and umbrellas flying away. Stick to the shops on 5th Avenue South instead.
- UV Trap: Even on the "cool" 63°F day (Friday), the UV index is still a 4. You will get burned because you don't feel the heat. Apply sunscreen anyway.
Check the local radar specifically around 4:00 PM each day. In both cities, this is usually when the weather "decides" what it wants to do for the evening. In Italy, the clouds often break just before sunset, giving you a killer view of Vesuvius if you're quick. In Florida, that’s when the sea breeze either dies down or brings in a quick, weird shower.
Monitor the overnight lows if you're sensitive to cold. Those 41°F nights in Florida can be a shock if your rental's AC/Heating system isn't prepared for it. Likewise, the 42°F nights in Italy mean you’ll want to make sure your accommodation has "riscaldamento" (heating) turned on—some older buildings have strict dates for when they allow the heat to be used.
