With increasingly high temperatures in August and September, you might be wondering how to enjoy London without getting overheated. Finding relief in a city not traditionally built for such heat can be challenging. Fortunately, London offers plenty of opportunities to cool down, if you know where to look. Here are a few tips on how to escape the baking sun during London’s summer heatwaves.
Head to London’s Outdoor Swimming Pools
For fans of swimming, London has several outdoor pool options — also known as lidos — that are the perfect spot for activities on a warm summer day.
- London Fields Lido: This heated outdoor pool remains cool enough for a swim during a heatwave. It’s a popular spot with visitors and locals alike, so we recommend getting there early.
- Tooting Bec Lido: One of the largest outdoor swimming pools in the United Kingdom, Tooting Bec Lido is a South London oasis with plenty of space to cool off.
Relax in a London Park
London’s parks become even more of a gem than they already are when the city gets hot. In general, their trees offer plenty of shade for a refreshing escape outdoors. Here are a few London favorites:
- Hyde Park: One of the largest green spaces in London, Hyde Park has loads of shaded areas situated under ancient trees. If you’re feeling adventurous, you can also rent a paddleboat on the Serpentine Lake or go for a swim at the lido.
- Hampstead Heath: For something that feels a bit more rugged, Hampstead Heath is a perfect spot to take a break from the heat. With beautiful ponds and the Parliament Hill Lido, you can enjoy swimming in the open air.
- Kew Gardens: If you’re in the mood for something more serene, Kew Gardens is a great choice. Wander through cool, shaded paths lined with exotic plants and trees. Don’t miss the air-conditioned greenhouses for a bit of extra relief.
Cool Off Along London’s Waterways
London’s historical waterways are also a great option for staying cool. Some top ways to explore on the water include:
- A Trip with Thames River Sightseeing: Take a leisurely cruise along the Thames. The breeze from the water combined with scenic views make this excursion a perfect way to cool down.
- Visit Regent’s Canal: Rent a kayak or take a canal boat ride along Regent’s Canal. The water and foliage provide a cooler microclimate than the surrounding areas.
Seek Shelter in Historic Buildings
Many of London’s historically significant buildings naturally stay cool in the summer because of their thick walls and high ceilings. Some great locations to visit include:
- Westminster Abbey: The ancient stone walls and majestic interiors of the abbey provide a cool sanctuary from the heat.
- The Tower of London: Explore the historic towers and chambers of this famous fortress, where the temperature inside remains cooler than outside.
Plan a Day Trip to the Coast
If you can’t find a spot cool enough for your preferences in London, escape to the seaside! Nearby coastal destinations include:
- Brighton: Just an hour away by train, Brighton is a vibrant beach scene with plenty of ocean breeze and offers guests the chance to swim in the English Channel.
- Whitstable: A charming coastal town known for its oysters, Whitstable’s shingle beaches and cool sea air is a great choice for those seeking a quieter destination.
With these tips from Thames River Sightseeing, you’ll breeze through London’s heatwaves like a pro (and have a blast while doing so). Whether you prefer relaxing in parks or taking a refreshing dip in outdoor pools, London has plenty of locations to help you stay cool and keep the fun rolling — even on the hottest days!
