Hanging out by the riverside is an integral part of London’s summer culture. Lazy afternoons spent at the city’s riverside pubs and bars eating, drinking and catching up with friends is a popular summer activity where you can enjoy the warmth of the sun on your skin while enjoying alfresco dining. Some of the popular riverside neighbourhoods in London include Richmond, Hammersmith, Greenwich, Fulham, Tower Bridge, Putney and Wandsworth which are all brimming with pubs and bars by the river. On hot days you’ll find that the riverside is buzzing with plenty of young locals using the great weather as an excuse to get sloshed. Pretty good excuse if you ask us.

What’s summer without a picnic? While people associate London as being cloudy and gloomy most of the time, in the heat it’s an ideal place for a picnic due to the sheer amount of beautiful parks that exist in the city. In fact, 47% of London is made of green space which is almost half of the city!

There are also 8 million trees in the city to set up a picnic blanket in the shade. Our favourite Royal parks include Hyde Park, St James’ Park, Richmond Park and Regents Park. Then there also the non-Royal parks which are also worth visiting such as Battersea Park and Clapham Common. Buy yourself some food from a local supermarket, get a few drinks, get a picnic blanket and you’re ready for a day in the sun enjoying London’s green spaces.


Need a plan for a summer’s evening in London? The open air cinemas in the city are a great choice, especially for Date Night or a fun movie night with friends. The Rooftop Film Club has finally reopened in locations across London including Bussey Building in Peckham and Roof East in Stratford which are both located on the rooftop. Here you can watch all the latest films as well as the much-loved classics and legendary chick flicks surrounded by the warm evening air from a summer rooftop in London.

London's ice cream game is strong, meaning on a hot summer's day your gelato cravings are in for a treat! Dessert cafes and artisan ice cream shops can be found all over the city serving up your favourite classics as well as a few whacky flavour combinations here and there. From creamy gelato to refreshing sorbets and dairy-free tubs of deliciousness, whatever your favourite style of ice cold dessert may be, London won't disappoint. Amorino, Gelateria 3bis and La Gelatiera are a few of our top picks. If you find yourself in one of London's parks on a hot day, or even just near the river, you may be able to find a classic old ice cream van parked nearby ready to rustle you up a satisfying Mr Whippy with a flake. Does anything really beat it?


If you’re looking for an enjoyable daytime activity that will fill a few hours, then you can’t miss London Zoo, the world’s oldest scientific zoo. The majority of the exhibits are located outside, perfect for a day of mooching around in the sunshine.

When the sun is out, it’s the perfect time to explore beautiful areas on the outskirts of the city. For a memorable on a hot day, Windsor is a popular destination for visitors where you can easily fill a whole day when the sun is out. This historic town is located in Berkshire, home to the famous Windsor Castle (a Royal residence where the Queen often lives) where you can visit the State Rooms, go inside St George’s Chapel and wander the Royal grounds. Boasting over 900 years of Royal history, you simply must pay a visit to the castle where Prince Harry and Meghan Markle got married.

Windsor is also home to a beautiful High Street filled with independent shops, restaurants and bars, pretty walks and green spaces like Windsor Great Park and the Long Walk, afternoon tea cafes, cobbled streets and beautiful architecture. Everything is better in the sun right? From London you can get to Windsor by train from London Paddington or Waterloo via Slough.

Top tip: If the flag is up on the Windsor Castle tower, it means the Queen is in!


If you consider yourself a bit of an adrenaline junkie then get your friends together and visit Thorpe Park for a day of fun. This famous theme park is located on the outskirts of London in a small town in Surrey between Chertsey and Staines. When the sun is shining, it’s the best time to visit to make the most of the fast rides, ice slushies and activities. There are water rides to cool yourself down in the scorching heat; our favourites are Tidal Wave, Rumba Rapids and Loggers Leap. Thorpe Park is also home to the UK’s fastest roller coaster called Stealth. Can you brave it? To get to Thorpe Park from London you have to catch a train from Richmond station to Staines. There is a shuttle bus link (number 950) which operates directly from Staines to Thorpe Park approximately every 15-20 minutes.

One of our favourite place to relax in the sunshine to catch some rays is Primrose Hill, close to Regent’s Park and London Zoo. This large grassy space is located high on a hill boasting some incredible views of central London where you can see the London Eye in the distance. The hill is actually one of the six protected viewpoints in the city with the top almost 63m above sea level. The best sunbathing spot in the city! Just buy a couple of beers and you’re ready to relax.


Fancy a refreshing cocktail at one of London’s coolest affordable rooftop bars? Enjoy the summer sun with other Londoners who pack out the city’s rooftops in the summer months for some alfresco drinking. Not all rooftops in London are super expensive; we’ve rounded up the .

Not exactly a rooftop bar but an awesome terrace in the city, we also recommend visiting Somerset House in Covent Garden where you can enjoy the terrace bar overlooking the river, a great place to enjoy the sunset.


There is no better place to visit in London for nature lovers than Kew Gardens, a world-famous botanical garden and UNESCO World Heritage Site in West London. With 300 beautiful acres to explore, visitors can enjoy the flora and variety of plant species, wildlife, Victorian greenhouses, a beehive installation and the stunning Rock garden.

One of the best activities on a hot day has to be crazy golf or mini golf. It always gets a bit competitive and it’s a fun way to be outdoors with your mates. The cool thing about London is that you can play mini golf all year round with its indoor and outdoor venues. For a hot day, we’d recommend Putt in the Park which has mini golf locations in Battersea, Wandsworth and Acton Park. For a spot of crazy golf,  you can test the fun holes at Plonk in London Fields. Make sure to book your slot in advance online.


Stuck on what to do when it’s hot in London? Have no idea where to go? Just head to London’s Southbank, the city’s cultural district where you’re sorted for a day of enjoyment.
