May is the month when the English springtime blossoms into warmer days. It isn’t as hot as June weather can potentially be, and you might still notice hints of coolness in the air, especially in the evening. But May is a lovely month all round. I’ve definitely put away winter clothes by May and I’m wearing lightweight jackets, cotton trousers and summer dresses. You’ll still need to pack jumpers though – and an umbrella!

May public holidays in London
We have two public holidays (traditionally called bank holidays) in the United Kingdom in May. They both fall on Mondays. Early May Bank Holiday is 4 May in 2026. Whilst at the end of the month Spring Bank Holiday is on 25 May 2026.
Londoners tend to get out and enjoy their city on a public holiday. Banks are closed (hence the name) and so are schools and most businesses including doctors’ surgeries, although hospitals are open. Shops and restaurants tend to stay open on bank holidays these days, although shopping hours may be reduced. Transport services are often affected too.
Most London attractions and theatres stay open for the Spring Bank Holidays, but check in advance for opening times and booking requirements.
Things to Do in London in May
May is the perfect time to explore the city, visit attractions without the summer queues and make the most of time outdoors. The warmer weather makes outdoor activities more inviting whilst longer days are a good opportunity to head further afield.
The month of May also sees the kick off of London’s traditional ‘season’, a whirl of social events during the summer months. Once the preserve of aristocrats, many of these sporting or cultural events have become much-loved institutions. And these days they are ticketed events that anyone can attend.
Enjoy the spring flowers in London in May
London begins to bloom in April and is in full throttle by May. Officially it’s the month when elegant purply pink wisterias come into flower on the facades of central London mansions and in city parks. Although occasionally they flower earlier in April. Whenever they do it sparks ‘wisteria hysteria’ in social media channels!
Wisteria or not, May is a magical time of year for a walk in a London park. As well as formal bedding displays like the tulips outside Buckingham Palace, you’ll find wilder swathes of bluebells, kaleidoscopic groves of rhododendrons and azaleas, lilacs and roses.
All the royal parks in central London are worth a visit. Hyde Park sprawls between Westminster and Kensington, pretty little St James’s Park nestles beside Whitehall and Regent’s Park, also home of London Zoo, is on the doorstep if you’re sightseeing north of Oxford street. Getting outside and enjoying the city’s natural beauty is one of the best things to do in London in May.
Kew Gardens With the spring in full swing, the Royal Botanic Gardens, beside the Thames at Kew, is a lovely place for an outing. See carpets of bluebells, a dell of rhododendrons and all the year- round wonders in the Victorian glasshouses.
Spend time outdoors in London in May
May is often perfect weather for walking. This is the way to really get to know London’s streets and to spot little gems that you miss altogether when you whizz from stop to stop by tube. Since the pandemic, London has enthusiastically embraced the concept of pavement cafes. So you can while away an hour or two with a coffee in a characterful corner of central London and watch street life unfold.
History buffs can discover London’s historical places. And walking tours will give you fascinating insights from a local expert.
See the sights from river boats and open top buses
A dinner cruise along the Thames is especially fun in May. Longer days mean you’ll see some of London’s best loved landmarks bathed in golden hour light as the sun sets. Then as darkness falls watch as the bridges and waterside buildings flicker to life once again with their nighttime illuminations. Book ahead to secure your place here.
During the day, catch one of the regular river boats to get from A to B across town as an alternative to the London tube.
Or hop on a tour boat for a trip along the canal between Little Venice and Camden Lock. You can be your own skipper too and rent an electric Go Boat (with heated seats and blankets) for a tour of the waterway.
One of the most time-honoured ways to see London’s sights is from the open top of a vintage London Routemaster bus. A sunny day in May is perfect for this. Save your soles and sit back to enjoy the iconic ride. Top tip: take a warm jacket just in case! Book London: Guided Sightseeing Tour on a Vintage Open-Top Bus here.
Enjoy a pub with river views
Once the sun comes out, sitting beside the water at a pub to enjoy a pint or a Pimms, is one of the quintessential London experiences. Great places to try include riverside pubs like The Dove or the Blue Anchor at Hammersmith or the Mayflower at Rotherhithe.
Watch an outdoor theatre performance
Many visitors to London plan to book seats for a West End show. But catching an open air theatre performance or concert is a classic London activity in the warmer months.
The iconic Regent’s Park Open Air Theatre seats over 1000 and is a much-loved venue for opera and Shakespeare. Bring sun cream and/or waterproofs. The added peril of not knowing when it might rain never seems to dampen Londoners’ enthusiasm.
Or visit Opera Holland Park in west London where artists and audience are protected from the elements by a canopied auditorium.
Shakespeare’s Globe Theatre is another famously open-air venue, and a unique opportunity to see plays as they were originally experienced by their 16th and 17th-century fans.
Glyndebourne in East Sussex is a 500 year old country house and the venue for the world-famous Glyndebourne opera festival. The performances are held in an indoor auditorium and opera lovers dress up for the occasion and picnic on the lawns, It’s a very ‘English’ event. The season begins in May and runs until the end of August. It’s only an hour from London by train to Lewes.
London music festivals. London hosts a vast range of outdoor festivals and live performances during the summer months, check the listings for up to date information.
Visit an outdoor antiques market
If your heart beats faster on an early morning antiquing foray then Sunbury antiques market at Kempton Park racecourse is waiting. One of the largest antiques fairs in the UK, with more than 700 traders and stock from all over Europe, it’s a complete treasure trove. It’s open to the public from 8 am on two Tuesdays a month. There’s free parking or catch a train from Waterloo station – it takes 45 mins. Get there early and know that cash is preferred. If you love antiques you’re going to enjoy this!
Enjoy fewer crowds at popular attractions
As part of London’s shoulder season, late spring is the best time to make the most of the top tourist attractions. The city is by no means empty in May but you’ll be bypassing the peak crowds of the summer months. So you’ll have a little more room to enjoy a couple of hours at the Tower of London, or watching the ceremonial parades on the Mall.
On rainy days in May London offers plenty of indoor entertainment. You can browse the British Museum or National Gallery for free or head to Covent Garden or one of our world-class department stores for some excellent shopping.
Harry Potter fans will also find that the Warner Brothers studio are quieter on weekdays and during the UK school term time.
Take in some bird’s eye views of London
All London’s viewing platforms are best enjoyed in fine weather and May is a sweet spot in the calendar before the crowds of peak season. The London Eye, the Shard and the Sky Garden are all well known. But you can also get good outdoor views from Tower Bridge, the dome of St. Paul’s Cathedral (if you don’t mind all the steps!) and skyline panoramas from Hampstead Heath and Primrose Hill.
Sample London’s famous street food
Pleasant temperatures make it a treat to eat outdoors and May is a great time of year to discover London’s food markets.
You can sample a truly global mix of dishes by exploring the stalls at food markets like Brick Lane, Borough Market or the Southbank Centre by the Thames. Check locations for opening days and times.

Take a day trip into the English countryside
May is also a great time of year to do some sightseeing outside the city, especially during the UK school term time. Some of the best of England’s countryside is within reach of London and popular good value tours can whisk you to Stonehenge, Bath or the Cotswolds in a day.
Visit Canterbury, Dover Castle and White Cliffs
Head to the Kent on the south coast to visit three fine English landmarks. This one day tour carries you effortlessly to the mighty Dover Castle, the White Cliffs of Dover and the historic city of Canterbury with its medieval cathedral. There’s time for a walk along the stunning chalk white cliffs as well as exploring a centuries-old fortress and picturesque Canterbury.

What to Wear in London in May
The problem with London weather in May is that it doesn’t always match up to the fun things you’d like to do. In an ideal world I’d float around Chelsea Flower Show in a summer dress and pretty sandals. When I tried that I was drenched in a flash downpour, staggering through the streets with an enormous azalea I’d snagged on the sell-off day. Year by year Chelsea Flower Show weather fluctuates from the not-quite-warm-enough – or dry enough – to the outright sizzling. Layers are the answer, with something shower proof to fall back on.
As you near the start of your London trip, check the London weather forecast at BBC Weather. This will give you an idea of the temperatures that are likely during your stay. Then pack with versatility in mind. Here are some suggestions based on my own experiences of the weather here in May.
What to Pack for London in May
- Coats and jackets: You won’t need a winter coat but you do require some rain gear, just in case, plus a warm jacket for cooler days. If you get caught out, pop into Uniqlo for an ultra light down jacket or gilet that packs down to next to nothing.
- Tops: Bring tee shirts and tops plus some relatively warm clothes as evenings can be chillier. Lightweight jumpers and cardigans are useful to add layers.
- Trousers etc: Jeans, trousers or longer dresses should be fine in May. A dress and jacket works well if you’re planning a dressy occasion.
- Shoes: Whatever the time of year you need some good walking shoes in London. Choose cushioned loafers or smart trainers that combine style and comfort and can tackle showers of rain as well as cobbled streets.
- Accessories: Sunglasses are a must-pack and a soft wrap or scarf can add an extra layer of warmth and/or style to your outfit.
- An umbrella: There’s a chance of rain in London at any time of year. Choose a lightweight folding umbrella that you can carry in a bag or coat pocket.
