Italy Naples Weather in December — Climate Guide
December in Naples is moderate
December is moderate for Naples.
December is mild for winter at 14°C/7°C but damp (about 115mm of rain), and it's Naples' magical Christmas season. The city is festive, with the Old Town's nativity-scene tradition at its peak.
Via San Gregorio Armeno, the world-famous 'Christmas alley,' is packed with presepe workshops and crowds in the run-up to Christmas — atmospheric and unmissable, if busy. The December 16 San Gennaro ceremony at the Cathedral is the year's third blood-miracle event. New Year's Eve brings lively fireworks over the bay.

Naples in December — Full Picture
December is mild for winter at 14°C/7°C but damp (about 115mm of rain), and it's Naples' magical Christmas season. The city is festive, with the Old Town's nativity-scene tradition at its peak.
Via San Gregorio Armeno, the world-famous 'Christmas alley,' is packed with presepe workshops and crowds in the run-up to Christmas — atmospheric and unmissable, if busy. The December 16 San Gennaro ceremony at the Cathedral is the year's third blood-miracle event. New Year's Eve brings lively fireworks over the bay.
Indoor sights — MANN, the Sansevero Chapel, Capodimonte, Naples Underground — are ideal in the changeable weather, and pizza and pastries are perfect cold-weather comforts. Day trips are weather-dependent: Pompeii on a dry day with warm layers; Capri/Amalfi ferries reduced and the Blue Grotto often closed.
Prices rise around Christmas and New Year but are otherwise reasonable. Pack a warm jacket, a scarf, and an umbrella, and enjoy one of Italy's most characterful Christmas cities.
What to Wear & What to Pack
Mild but damp winter — around 14°C/7°C. A warm jacket, sweaters, a scarf, and an umbrella. Layers handle chilly mornings and milder midday sun.
