Monthly weather averages & travel planning

Europe › 🇫🇷 France › Nice
Updated: March 2026
December is a fair time to visit Nice (4/10). Average highs of 15°C and 1 sunshine hours daily make conditions workable, though not exceptional. December suits travellers visiting for indoor culture, food, and architecture rather than outdoor activities. Pack accordingly for 7 potential rain days. January offers a similar profile at lower hotel rates if dates are flexible. The main practical note: Nice's popular sites are busiest between 10am and 3pm regardless of season. Arriving at opening time or after 4pm makes a significant difference to the experience. Planning tips: most accommodation categories have availability, and last-minute deals are common. The quieter streets and shorter queues can make this a genuinely enjoyable time to visit for the right type of traveller. Budget-conscious visitors will find the best value of the year in this period.
Nice's December weather is shaped by atmospheric forces that make the data more than just numbers. The 15°C average high reflects a transitional pressure pattern where mid-latitude westerlies alternately bring mild maritime air and cooler polar intrusions. As a result, 1 daily sunshine hours are recorded on average, and rainfall of 80mm is distributed across approximately 7 days because precipitation events tend to be brief and infrequent.

The 9°C day-night temperature range is typical for continental climates: a light jacket in the morning that you shed by midday and need again after sunset. Humidity averages 65%, which is comfortable for most visitors. On warmer days, lighter fabrics help with the mild stickiness in the afternoon. The UV index of 1 is low, meaning sun exposure is minimal concern and sunscreen is largely optional. Wind averages 15 km/h, light enough to be refreshing on warm days but noticeable in open coastal areas or elevated viewpoints. In Fahrenheit: 59°F average high, 43°F overnight low. Data sourced from Open-Meteo ERA5 climate reanalysis (1991–2020 normals).
Packing for Nice in December means dressing for 15°C days and 6°C evenings. A mid-weight jacket over a sweater handles 15°C daytime temperatures; the combination stays comfortable all day without overheating. Evening temperatures settle at 6°C, a modest 9°C drop that a light cardigan or denim jacket covers. European cobblestones reward low-profile walking shoes over flip-flops or heels, with cushioned trainers or leather walking shoes being the practical choice.
Local tip: Many of Nice's museums and galleries maintain cool interior temperatures regardless of outdoor conditions. A compact layer in your daypack lets you move between warm streets and chilled exhibition halls without discomfort.
December has no major festivals or public holidays in Nice, which is one of its practical advantages for independent travellers. Attractions run at lower capacity than during peak event periods, queues are shorter, and accommodation is easier to find without needing to book many months in advance. Local restaurants, markets, and transport operate at a relaxed pace, making this an ideal time for visitors who prefer a more authentic, unhurried experience of everyday city life rather than large crowds drawn in by a single major headline event.
Based on 15°C average highs and 7 rainy days
In December, the Azores High weakens and retreats southward, allowing Atlantic storm tracks to cross the Mediterranean and bring the city its seasonal rainfall. Temperatures average 15°C during the day and drop to 6°C at night as cold continental air occasionally pushes in from the north. This is the rainy season that keeps the region's landscape green through spring. Climate data: Open-Meteo ERA5 (1991–2020).
Sunshine Hours
The average number of hours per day with direct sunlight. Calculated from satellite measurements. Days with more than 7 hours of sunshine are ideal for outdoor activities. Under 3 hours means overcast conditions dominate.
UV Index
A scale from 0-11+ measuring ultraviolet radiation intensity. UV 0-2: Minimal risk. UV 3-5: Moderate, wear sunscreen. UV 6-7: High, hat and SPF 30+ essential. UV 8-10: Very High, limit midday exposure. UV 11+: Extreme, seek shade between 10am-4pm.
Rain Days
A rain day is counted when precipitation exceeds 0.1mm. This threshold captures even light drizzle. Unlike total rainfall in mm, rain days tells you how often you might need an umbrella, which is useful for planning outdoor activities.
Humidity
Relative humidity as a percentage. Below 40%: Dry, skin and throat may feel parched. 40-60%: Comfortable, ideal for most people. 60-80%: Sticky, light breathable fabrics recommended. Above 80%: Muggy, heat feels more intense; quick-dry clothing is essential.
