Is December a Good Time to Visit Prague?
3/10
Avoid
December is a avoid time to visit Prague (3/10). Average highs of 4°C and 4 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 10 potential rain days. Prague Christmas Markets takes place this month, adding cultural value for those planning around it. The 4°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.

The UV index of 1 is low, meaning sun exposure is minimal concern and sunscreen is largely optional.

Packing for Prague in December means dressing for 4°C days and -1°C evenings. Layering is key: a thermal base, mid-layer fleece, and a windproof outer jacket for 4°C highs that feel colder in the wind. Evening temperatures settle at -1°C, a modest 5°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. A compact foldable umbrella weighs almost nothing and earns its keep across 10 potential rainy days.
Local tip: Many of Prague'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.

Why is Prague cool in December?
In December, Prague 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 4°C during the day, dropping further to -1°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.
