Overview of London’s December Climate
London experiences a temperate maritime climate, meaning winters are generally cool and damp rather than severely cold. December is one of the coldest months, but temperatures rarely plummet below freezing for extended periods. Snow is possible but not guaranteed; sleet and rain are more common.
Average Temperatures
Daytime highs in December typically range from 7°C to 10°C (45°F to 50°F), while overnight lows hover around 2°C to 5°C (36°F to 41°F). On some days, the temperature may dip to just above freezing, especially in the early mornings. However, it is unusual for London to experience prolonged sub-zero temperatures.
Rainfall and Precipitation
December is one of the wettest months in London, with an average of 11 to 13 rainy days. Total precipitation is around 55 mm (2.2 inches). Rain often comes in the form of light drizzle or short showers, but heavy downpours can occur. Snowfall is infrequent; when it does snow, it typically melts within a day or two.
Daylight Hours
December has the shortest days of the year. Sunrise is around 8:00 AM, and sunset is as early as 3:50 PM, giving you roughly 7 hours and 45 minutes of daylight. This limited daylight means you should plan outdoor activities between late morning and early afternoon.
What to Expect: Weather Patterns and Variations
While the overall climate is consistent, weather in London can change rapidly. A typical December day might start with fog, turn to drizzle by midday, and clear up to a crisp, cold evening. It is not uncommon to experience all four seasons in one day.
Fog and Mist
London is famous for its fog, though the thick “pea-soupers” of the past are rare. However, misty mornings and low cloud cover are common in December, reducing visibility and making the city feel even colder. Fog usually dissipates by late morning.
Wind
Winds are generally moderate, averaging 15–25 km/h (10–15 mph). Stronger gusts can occur during storms, but London is not particularly windy compared to coastal areas. Wind chill can make temperatures feel several degrees colder, so layering is essential.
Packing Tips for London in December
Knowing what the weather is like in London in December will help you pack smartly. The key is layering and waterproofing.
- Warm layers: Thermal tops, sweaters, and a fleece or mid-layer.
- Waterproof jacket or coat: A windproof and waterproof outer layer is essential.
- Scarf, hat, and gloves: These are crucial for warmth, especially in the evenings.
- Comfortable waterproof shoes or boots: London streets can be wet and slippery.
- Umbrella: A compact, sturdy umbrella is handy for sudden showers.
- Lightweight clothing for indoors: Many attractions and restaurants are well-heated, so you may need to remove layers.
Activities and What to Do
Despite the cold and rain, December is a wonderful time to explore London. The city is beautifully decorated, and there are many indoor and outdoor attractions.
Christmas Markets and Lights
Winter Wonderland in Hyde Park, the Southbank Centre Winter Market, and the Christmas lights on Oxford Street, Regent Street, and Covent Garden are must-sees. These outdoor events are best enjoyed with warm clothing and a thermos of hot chocolate.
Indoor Attractions
Museums like the British Museum, the Natural History Museum, and the Tate Modern are free and offer a warm refuge. Other indoor options include the Tower of London, Westminster Abbey, and the Churchill War Rooms.
Ice Skating
Ice skating rinks pop up across the city, such as at Somerset House, the Natural History Museum, and Canary Wharf. These are great fun but can be very crowded; book tickets in advance.
How Does December Compare to Other Winter Months?
December is generally colder and wetter than November but slightly milder than January and February. January is typically the coldest month, with average lows around 1°C (34°F). February is similar but with slightly more daylight. If you prefer fewer crowds and lower prices, January might be a better option, but December offers the festive atmosphere.
