December in Paris presents a city transitioning into the heart of winter, where the festive season begins to weave its magic through the chilly air. Average conditions are defined by cool temperatures that rarely plunge into extreme cold, but often settle into a persistent dampness that seeps into the bones. Travelers should expect a mix of overcast days, sporadic grey skies, and the occasional bright clearing, all contributing to the atmospheric backdrop for the city’s renowned holiday illuminations.
Temperature and Feel
Average daily high temperatures in Paris during December hover around 6°C (43°F), while overnight lows typically drop to 1°C (34°F) or sometimes even below freezing. This combination creates a climate that feels significantly colder than the thermometer suggests, thanks to the moderate to high humidity common in the city. The "feels like" temperature is often closer to freezing, demanding warm layers, a quality winter coat, and sturdy footwear for any extended time outdoors.
Daily Temperature Range
Sunlight is scarce in December, with the day lasting only about 8 hours, from roughly 8:30 AM to 4:30 PM. This limited daylight means that temperatures have little opportunity to rise significantly, maintaining a consistently cool environment throughout the day. Mornings start bitterly cold, and while there might be a slight afternoon thaw, the chill returns swiftly after sunset, reinforcing the need for warm clothing at all times.
Precipitation and Sky Conditions
Rain is the primary form of precipitation in Paris during December, rather than snow. The month sees an average of 50 to 60 millimeters of rainfall distributed across approximately 11 to 13 days. These are not usually torrential downpours but rather persistent drizzles or moderate showers that can last for hours, contributing to the city’s glossy, reflective streets and the dampness in the air.
Expect frequent overcast skies that block direct sunlight.
Grey, muted light is the dominant feature of the Parisian sky.
Occasional clear or partly cloudy days provide brief relief and stunning views.
Snowfall is infrequent and usually light, melting quickly upon contact with the ground.
Wind and Atmospheric Factors
While Paris is not known for strong winds, December can bring a noticeable chill with a light to moderate breeze, particularly coming from the northwest. This wind, combined with the high humidity and low temperatures, creates a penetrating cold that feels more intense than the actual temperature. It is this wind chill effect that makes a scarf and a proper coat essential accessories for navigating the city comfortably.
What to Pack for December
Packing for Paris in December is about balancing warmth, practicality, and style. The focus should be on high-quality layering pieces that allow you to adjust to indoor heating and outdoor cold. A waterproof outer layer is non-negotiable, as is an umbrella, to shield you from the frequent drizzle that defines the month’s weather.
Thermal base layers or thick sweaters for insulation.
A warm, water-resistant winter coat or a heavy wool trench.
Waterproof boots with good traction for potentially slick cobblestones.
An umbrella and a scarf to combat wind and rain.
Gloves, preferably waterproof, for warmth during outdoor excursions.
