In December, you should wear layered clothing suitable for temperatures ranging from a high of 57°F to a low of 46°F. Since the Castel Nuovo waterfront area can be prone to salt spray and damp winds, it is essential to bring windproof layers and waterproof outerwear.

Based on typical December conditions in Naples. Weather varies year to year — check the live forecast when you're within two weeks of your trip.
December in Naples brings a mild but crisp Mediterranean winter atmosphere, characterized by occasional rain showers and cool sea breezes. Visitors often find that exploring the Lungomare waterfront requires extra protection against damp winds and sudden rain, making it important to prepare for shifting weather patterns while walking along the coast. The city's aesthetic blends high-fashion flair with practical necessity, especially when navigating its historic terrain. Whether you are taking in the views from the steep hills of Posillipo or visiting landmarks like Castel Nuovo, having sturdy walking shoes and versatile layers will ensure you can transition seamlessly from breezy waterfront walks to cozy indoor cafes.
A black rain jacket over an oversized graphic tee and olive cargo trousers handles mild rain practically. White lace-up booties finish the look with enough contrast to lift the palette.
A grey longline coat over an ivory blouse and black wide-leg trousers handles mild rain without losing formal intent. Black Chelsea boots and a mini bag keep it focused.
A black longline parka over a cable knit sweater in mild rain keeps warmth without overdressing. Black mule heels under leggings are an unexpected and intentional detail.
A navy trench coat over khaki bermuda shorts and a blue linen blouse works between seasons on a mild rainy day. Black pointed-toe heels sharpen what could easily be too casual.
A cream oversized puffer over a navy striped cardigan and wide-leg ivory linen trousers handles mild rain with a considered mix of textures. Black ballet flats are the restrained finish.
An olive anorak handles mild rain without abandoning the polish of wide-leg navy trousers underneath. The crossbody stays tucked and close.
A blush cropped jacket over a grey cardigan and black sweater mini skirt handles mild rain with charm. A black bucket bag and ankle boots keep the proportions balanced.
In December, focus on smart layering to handle the mild but unpredictable weather. Wear light sweaters or knits over shirts, and always have a medium-weight jacket or windproof coat ready for when the temperature drops or sea breezes pick up.
December is a wonderful time to visit if you enjoy a milder climate and want to avoid the intense summer heat. While there may be more rain than in the summer months, the city's festive atmosphere and fewer crowds make it an ideal time for exploring historic sites comfortably.
You should prioritize sturdy, comfortable walking shoes with good grip. The steep hills of Posillipo and the uneven cobblestone streets throughout the city center can be slippery if it rains, so avoid heels or smooth-soled shoes.
Naples remains relatively mild for a winter month, with average highs around 57°F and lows near 46°F. However, the humidity from the sea and wind off the coast can make it feel significantly chillier than the thermometer suggests.
Pack a versatile wardrobe including light sweaters, long-sleeved tops, a waterproof jacket or trench coat, and comfortable walking shoes. It is also wise to include an umbrella, a scarf for breezy evenings, and perhaps some thermal layers if you plan on visiting higher elevations like Mount Vesuvius.
