London Weather Overview
London has a mild oceanic climate, meaning extreme temperatures are uncommon throughout the year.
Rather than dramatic seasonal changes, London experiences gradual shifts in weather, with occasional rain possible throughout the year.
Here’s a general overview:
| Season | Weather | Crowds | Budget |
| Spring (Mar–May) | Mild and fresh | Moderate | Moderate |
| Summer (Jun–Aug) | Warm | High | Expensive |
| Autumn (Sep–Nov) | Cool | Moderate | Moderate |
| Winter (Dec–Feb) | Cold | Mixed | Lower (except Christmas) |
Although London has a reputation for rainy weather, continuous all-day rain is less common than many people expect. Short showers are much more typical, which means carrying a lightweight umbrella is usually enough.
Knowing what to expect each season makes it much easier to choose the right time for your trip.
Spring in London (March to May)
For many travelers, spring is the most balanced season to visit London. Temperatures become comfortable after winter, flowers begin blooming across the city, and popular attractions are noticeably less crowded than during peak summer.
Average temperatures range between 9°C and 18°C (48°F–64°F), depending on the month. Spring is one of the best times to explore London’s famous parks, with blooming flowers and comfortable walking weather.
Visitors can enjoy beautiful displays of flowers in places such as:
- Hyde Park
- Kensington Gardens
- Regent’s Park
- St James’s Park
Outdoor cafés become livelier, and locals begin spending more time in the city’s parks and gardens.
Why Visit London in Spring?
- Comfortable walking weather
- Beautiful gardens and parks
- Longer daylight hours
- Moderate hotel prices
- Great season for first-time visitors
Things to Consider
Spring weather can change quickly.

Summer in London (June to August)
Summer is London’s busiest travel season, and for good reason.
The city comes alive with outdoor events, festivals, riverside dining, and long evenings that encourage visitors to stay out well after dinner.
Temperatures usually range from 18°C to 26°C (64°F–79°F), although occasional heatwaves can push temperatures above 30°C.
One of the biggest advantages of visiting during summer is the extra daylight. In late June, sunset is often after 9 PM, giving you plenty of time to explore without feeling rushed.
If you’re planning a short trip, our London Itinerary for 3 Days shows how to make the most of those long summer evenings while covering London’s top attractions efficiently.
Popular outdoor experiences include picnics in Hyde Park, riverside walks along the South Bank, open-air theatre performances, and rooftop bars overlooking the city skyline.
Why Visit London in Summer?
- Long daylight hours for sightseeing
- Lively atmosphere throughout the city
- Outdoor festivals and seasonal events
- Ideal weather for walking between attractions
Things to Consider
Summer is also the busiest and most expensive season. Hotels often charge their highest rates, and famous attractions such as the Tower of London, Buckingham Palace, and the London Eye can become crowded, especially during school holidays. Booking accommodation and attraction tickets well in advance is highly recommended.
Check-in Pick Insight
If you’re visiting London in July or August, start your sightseeing early in the morning. Many of the city’s most popular attractions become noticeably busier after 10 AM, while the first few opening hours are usually much more relaxed.
Autumn in London (September to November)
Autumn doesn’t receive as much attention as spring or summer, but many experienced travelers consider it one of London’s best seasons.
The summer crowds begin to disappear, temperatures remain comfortable in September, and the city’s parks gradually turn shades of gold, orange, and red.
Average temperatures range from 10°C to 20°C (50°F–68°F).
September still feels pleasantly mild, while October offers crisp weather that’s ideal for walking. By November, cooler temperatures become more noticeable, and you’ll want a warm jacket for evenings.
Autumn is a great season for museum visits, afternoon tea, and exploring London’s historic neighborhoods without the peak-season crowds. It’s also an excellent time to discover many of the free attractions in London, from world-class museums to beautiful public parks.
Why Visit London in Autumn?
- Comfortable sightseeing weather
- Fewer tourists than summer
- Beautiful autumn scenery
- Better hotel prices compared with peak season
Things to Consider
Daylight becomes shorter as autumn progresses, so planning outdoor activities earlier in the day is a good idea.
Packing a waterproof jacket is also recommended, as occasional rain showers remain possible.

September is one of the best months for travelers who want a balance between good weather and manageable crowds. You’ll often find that popular landmarks feel less hectic than they do during the height of summer.
Winter in London (December to February)
Winter reveals a quieter and more festive side of London.
The weather is colder, daylight hours are shorter, and rain is more common, but the festive atmosphere makes December one of the city’s most memorable months.
Average temperatures usually stay between 2°C and 9°C (36°F–48°F).
Christmas lights decorate major shopping streets, seasonal markets appear across the city, and many visitors travel specifically to experience London’s holiday atmosphere.
