Which Is the Best Season to Visit London?
London’s summer season is full of action with main happenings, autumn provides a pleasant London climate and rich culture, and winter brings the joy of holidays along with excellent budget offers. The difference in seasons brings out the various characteristics of the city, thus assisting tourists in the decision of the Best Time to Visit London.
1. Spring (March–May): Best Overall Season
Spring in London just feels right. The city wakes up parks and gardens burst into color, and that chill in the air isn’t too much. It’s usually somewhere between 9 and 17 degrees, so you can walk for ages or spend the whole day outside without feeling worn out. Hyde Park, Kew Gardens, and St. James’s Park all look their best now.
A lot is going on too. The Chelsea Flower Show, the Boat Race, and food and arts festivals breathe life into London, but it is not yet overcrowded with tourists. Of course, there is an increase in the number of visitors as spring comes to an end, but it is still much quieter than summer. Hotels won’t empty your wallet, and with the sun setting late, you’ve got extra time to get lost in the city.
Best for: Sightseeing, photography, families, first-time visitors
Downside: Occasional spring showers
2. Summer (June–August): Best for Events and Outdoor Activities

Energy level of summer in London is the highest. Daylight hours are extended, temperatures are cool (between 15°C and 24°C), and the city is very much alive with outdoor activities, resembling a massive festival. The peak period of street food markets, open-air cinemas, and concerts in London has been reached.
Wimbledon, Notting Hill Carnival (late August), British Summer Time concerts, and several cultural festivals are among the major events. The downside? It’s a period that is not only the busiest but also the most expensive. Prepare for long lines at tourist spots, very high hotel prices, and crowded public transportation.
Best for: Event lovers, families, nightlife, outdoor festivals
Downside: High prices, heavy crowds
3. Autumn (September–November): Best for Culture and Comfort
Autumn has all these elements that make the weather awesome, let you see fewer people, and let you experience the culture at its fullest. The temperature varies between 10°C and 20°C, and the city is decking itself out with the amber leaves of autumn that make it a great day for a walk in Richmond Park, Hampstead Heath, or Kensington Gardens.
September is truly a summer month and full of life, whereas October and November are packed with warm and cozy cafes, food festivals, theater season, and also the very first Christmas lights. It is overcrowded already, so you can more frequently have the pleasure of shorter lines and hotel discounts.
Best for: Couples, budget-conscious travellers, culture lovers, photographers
Downside: Rain increases toward late autumn.
4. Winter (December–February): Best for Budget Travel (Except Christmas)

There are two sides to winter in London. The month of December is Christmas season and it is during this time that Christmas markets, skating rinks, Winter Wonderland and the Christmas lights of the shopping areas, such as Regent Street and Covent Garden, attract people.
The post-New Year period and London become one of the most economical places to visit in Europe. The months of January and February offer the cheapest accommodation, calm streets, and limited visitors. The cold is noticeable (2° to 8°C), but with proper clothing, one can still enjoy winter.
Best for: Budget travellers, museum lovers, festive season enthusiasts
Downside: Cold weather, short daylight hours
