Weather in Nice in December

Nice in December suits a cool-weather city break, not a warm seaside holiday. Average afternoons reach about 12°C, nights fall to around 6°C, and about 8 days have rain. Go if you are happy walking in layers, taking indoor breaks and making the most of brighter spells. It is milder than London, but the catch is that short days, wet weather and a cold sea limit the outdoor holiday feel.

Milder than London, but still coat weather

The temperature difference from London is useful rather than dramatic: Nice averages 4.7°C warmer by day in December. That makes it a reasonable choice if you want less chilly afternoons without expecting summer warmth. The warmer days can reach around 15°C or more, so layers let you adjust when conditions improve. Evenings need a different approach, with average lows around 6°C and the coldest nights dropping to about 3°C or below. Pack a proper jacket, jumpers and closed shoes rather than relying on a light cardigan. This is weather for comfortable walking when dressed appropriately, not sitting outside in shirtsleeves.

Keep outdoor plans flexible

Rain is a meaningful drawback in December, with about 8 rainy days during the month. That does not mean every wet day is a washout, but it does make a rigid outdoor itinerary a poor fit. Bring a waterproof outer layer and shoes you are comfortable wearing on wet pavements, and leave room to change plans. There are about 4.2 hours of sunshine within 8.8 hours of daylight, so put your outdoor time into the brighter part of the day rather than leaving it until late afternoon. Nice suits travellers who can enjoy a dry spell without needing dependable sunshine throughout their stay.

Plan for the coast, not for swimming

The sea averages 15.5°C, which is cold rather than merely refreshing. For most holidaymakers, December is better treated as a time to spend beside the water than in it; do not make comfortable swimming the reason for booking. The wider decision is about priorities: Nice can work if you want a short journey and a milder setting for a winter city break, with the flight from London taking about 2 hours. It is a poor match if warmth and beach time are essential. If your dates are flexible, June, July and August are stronger choices for weather overall.
