Honestly, if you're looking at a weather forecast in sorrento italy 10 days out and seeing nothing but gray icons, don't cancel your flight just yet. Sorrento in January is a bit of a mood. It’s not the postcard-perfect, baking sun of July, but it’s far from a washout. Right now, as we hit mid-January 2026, the town is breathing. The summer crowds are a distant memory, and the air has that crisp, salty bite that makes a cappuccino taste ten times better.
Most people check their phone apps, see a 59°F high, and think "chilly." But that's not the whole story. The microclimate here, tucked between the mountains and the Tyrrhenian Sea, means the weather is constantly in flux. One hour you’re squinting against a blindingly bright sun hitting the limestone cliffs, and the next, a mist rolls in from the water that feels like a scene from a noir film.
Breaking Down the 10-Day Outlook for January 2026
If you're heading out this week, here is the ground truth. We’re looking at a stretch that starts off pretty decent before getting a bit more "authentic" (read: wet).
Today, Friday, January 16, it's mostly cloudy with a high of 59°F and a low of 52°F. It’s comfortable for walking, especially with just a light 7 mph breeze coming from the northeast. Tomorrow, Saturday, January 17, is actually looking like the winner of the week. It'll be sunny with a high of 60°F. If you’ve been waiting for that perfect shot of the Gulf of Naples, Saturday is your window.
But, because this is winter in Campania, the sky is going to pivot. Starting Sunday, January 18, we’re looking at light rain and showers, and that pattern holds through Monday, January 19, where the chance of rain jumps to 75%. The wind is going to kick up too—reaching about 16-18 mph from the east. It’s going to feel a lot colder than the thermometer says when that wind hits you on the Corso Italia.

By the middle of next week, from January 20 to January 22, the temperatures dip slightly. Expect highs around 54°F to 56°F and lows hovering right at 50°F. It’s going to be drizzly and damp. This is the "real" Sorrento winter. The streets get slick, the smell of woodsmoke from the hills drifts down, and the locals finally break out their heavy wool coats.
Why the Rain Isn't a Dealbreaker
You’ve got to understand how rain works here. It’s rarely a 24-hour deluge. Usually, it’s a series of quick, heavy bursts followed by dramatic clearing.
- Sunday, Jan 18: High 60°F, Low 54°F. Rain chance is 25% day / 65% night.
- Monday, Jan 19: High 59°F, Low 52°F. This is the wettest day with a 75% chance of rain.
- Tuesday, Jan 20: High 55°F, Low 50°F. Mostly cloudy with 35% chance of rain at night.
Basically, if you plan your museum visits or long lunches around those Monday and Tuesday windows, you'll be fine. The humidity is sitting around 64% to 68%, so it's a "wet cold." You’ll feel it in your bones if you aren't moving, so keep those walking shoes on.
What to Actually Pack (The Stuff Nobody Tells You)
Forget the linen shirts. You’ll look like a confused tourist and you’ll freeze.

The most important thing you can bring is a high-quality windbreaker or a light down jacket that’s actually waterproof. An umbrella is okay, but on the cliffs of Sorrento, the wind can turn a cheap umbrella inside out in seconds. A hooded jacket is a much smarter play.
Layering is the game here. You’ll want a base layer, a light sweater, and then your outer shell. Why? Because the sun in Sorrento is surprisingly strong even in January. If you’re hiking the Path of the Gods or just walking up the steep stairs from the Marina Grande, you’re going to get hot fast. But the second you step into the shade of a narrow alley, the temperature drops ten degrees.
Also, footwear. Cobblestones are treacherous when wet. I’ve seen enough people wipe out in smooth-soled "fashion" boots to tell you: bring something with grip. Rubber soles are your best friend.

Go to Pompeii. Seriously. While everyone else is hiding in their hotels, the ruins are incredibly atmospheric in the mist. Plus, there are no crowds. You can actually stand in the House of the Vettii without being elbowed by a tour group. Just wear waterproof boots because the ancient drainage isn't what it used to be.
Alternatively, stay in town and do a lemon-cello tasting or a cooking class. Sorrento is famous for its "Ovale di Sorrento" lemons. Even in the rain, the lemon groves are lush and green.
The sun sets early—around 4:59 PM this time of year. Use those dark, chilly evenings to tuck into a trattoria and eat Gnocchi alla Sorrentina. It’s heavy, cheesy, and exactly what you need when it’s 50°F and drizzling outside.
Looking Toward the End of the Month
As we head toward January 25, things look to be stabilizing. Highs will stay around 58°F with a mix of sun and clouds. The "Befana" festival is over, and the town is quiet. It's the perfect time for those who want to see the Amalfi Coast without the traffic jams.
Just remember: a Sorrento winter is about the light. The way the winter sun hits the water at 3 PM is unlike anything you’ll see in the summer. It’s a pale, silvery glow that makes the whole coastline look like a painting.
Next Steps for Your Trip:
Check the ferry schedules locally if you plan to visit Capri. High winds (like the 18 mph gusts predicted for next Tuesday) often mean the hydrofoils are canceled. Always have a "land day" backup plan involving a train to Naples or a bus to Ravello if the sea looks angry.
