Monthly weather averages & travel planning

North America › 🇨🇦 Canada › Quebec City
Updated: March 2026
December is a avoid time to visit Quebec City (2/10). Average highs of -3°C and 5 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 13 potential rain days. January offers a similar profile at lower hotel rates if dates are flexible. The -3°C highs require proper cold-weather clothing; many visitors underestimate how far the wind chill drops the perceived temperature, particularly near water or at elevated viewpoints. 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.
Quebec City's December weather is shaped by atmospheric forces that make the data more than just numbers. The -3°C average high reflects persistent high-latitude air masses that hold temperatures below the seasonal average for the region. As a result, 5 daily sunshine hours are recorded on average, and rainfall of 101mm is distributed across approximately 13 days because precipitation events tend to be frequent but short-lived.

The 8°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 17 km/h, light enough to be refreshing on warm days but noticeable in open coastal areas or elevated viewpoints. In Fahrenheit: 27°F average high, 12°F overnight low. Data sourced from Open-Meteo ERA5 climate reanalysis (1991–2020 normals).
Packing for Quebec City in December means dressing for -3°C days and -11°C evenings. Layering is key: a thermal base, mid-layer fleece, and a windproof outer jacket for -3°C highs that feel colder in the wind. Evening temperatures settle at -11°C, a modest 8°C drop that a light cardigan or denim jacket covers. Comfortable walking trainers are the versatile choice for both outdoor sightseeing and indoor venues. With 13 rain days expected, a compact travel umbrella is worth the bag space. A waterproof jacket is better than an umbrella if you plan full-day outdoor routes.
Local tip: Quebec City's -3°C days warm significantly in direct sunshine. A removable outer layer you can tie around your waist handles the midday warmth without leaving you cold on shaded streets or in the evening.
December has no major festivals or public holidays in Quebec City, 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 -3°C average highs and 13 rainy days
In December, Quebec City feels the full influence of the continental polar air mass, which dominates mid-latitude interiors during winter. Cold, dry air from the north suppresses temperatures to -3°C during the day, dropping further to -11°C at night when radiative cooling is greatest. Precipitation tends to be low, as the cold air holds little moisture. 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.
