Weather for Naples Today: What Most People Get Wrong About January

Honestly, if you’re standing in the Piazza del Plebiscito today, you’ve probably noticed the air has a bit of a bite to it. Most people think of Southern Italy as this permanent sun-drenched paradise, but January in Naples has a mind of its own. It’s moody. It’s damp. And today, Thursday, January 15, 2026, it is living up to that reputation with a mix of clearing skies and a lingering chill that catches you off guard if you’re just wearing a light sweater.

We’re coming off a morning where the clouds were heavy, and the rain was more than just a threat. In fact, if you were out early, you likely dealt with a 75% chance of rain that dominated the daytime forecast. But here’s the thing about Naples: the weather transitions fast.

Understanding the Weather for Naples Today

Right now, as we move into the evening hours, things are actually looking up. The current temperature is sitting at a steady 51°F, though with the wind kicking in from the north at 11 mph, it feels more like 47°F. You’ll want a proper coat if you’re heading out for dinner.

Basically, the "feels like" factor is the real story today. Humidity is hovering around 61%, which is actually quite dry for this city, keeping that "damp cold" from soaking into your bones quite as much as it did earlier this week. The UV index is a flat zero now that the sun has set, so no worries there.

The Breakdown of Your Evening

• Condition: Clear skies.
• Temperature: 51°F (dropping toward a low of 44°F).
• Precipitation: 0% chance for the rest of the night.
• Wind: 11 mph North.

Why Today’s Shift Matters for Travelers

If you’ve been following the news, you know that early January 2026 has been a mess for Italian travel. A massive Arctic air mass has been sitting over Europe, causing chaos from Amsterdam down to Rome. We’ve seen hundreds of flights delayed and even some wild scenes at airports like Brindisi where stranded passengers actually occupied the runway in protest.

Naples has mostly escaped the worst of the snow that hit the north, but the residual effect is this biting wind. While today’s high reached 67°F during the rainy afternoon—which is surprisingly warm for mid-January—the sudden drop to the mid-40s tonight is a classic example of why everyone here tells you to dress like an onion. Layers are your only hope.

Real Talk on the "Winter Warmth" Myth

People see a high of 67°F and think "t-shirt weather." It’s not.
When the wind comes off the Tyrrhenian Sea or down from the mountains, that 67°F feels much thinner. Plus, with a 22 mph northwest wind recorded earlier today, any heat from the sun was basically stripped away before it could reach you.

What to Actually Do in This Weather

Since the rain has cleared out for the evening, it’s the perfect time to walk the Spaccanapoli. The streets are less crowded because the locals tend to hide when the temperature dips below 50°F.

Honestly, the best move tonight is to find a pizzeria with a wood-fired oven. The heat from those ovens—which usually hit around 900°F—makes any restaurant feel like a sanctuary. You’ve got clear skies, so if you’re up for a bit of a breeze, the view of Vesuvius from Castel dell'Ovo will be crisp and sharp tonight.

Actionable Advice for the Next 24 Hours

1. Ditch the umbrella, keep the scarf. The 75% rain chance has passed, but the 11 mph north wind is staying through the night.
2. Check your flight status. Even though the weather for naples today is clear, the strikes across Italy and the residual delays from the European cold snap are still causing "knock-on" effects. If you're flying out of Capodichino tomorrow, check the boards before you leave the hotel.
3. Heat your room. Many older Neapolitan buildings have central heating that only runs at specific times (the "riscaldamento"). If you're in an Airbnb, make sure you know how to toggle the AC unit to heat mode now, before the 44°F low hits at 3:00 AM.

The weather is stabilizing. Tomorrow looks to be a bit more predictable, but for tonight, enjoy the clarity that follows a storm. Just don't forget that coat.
