London in April is one of the easiest months to combine classic sightseeing with spring parks and gardens. Expect cool mornings, milder afternoons, changeable rain, and cherry blossom that can peak from mid-March into April depending on the year. In 2027, major April dates include The Boat Race on April 11 and the two-day TCS London Marathon on April 24–25.
Quick Answer
Plan for a typical April daytime high near 15°C (59°F) and an overnight low near 6°C (43°F). For blossoms, prioritize Kew Gardens, Greenwich Park, The Regent’s Park, and St. James’s Park. Pack layers and waterproof outerwear, and allow extra travel time around major April 2027 events.

Key Takeaways
- Cherry blossom timing changes with the weather, so April is a strong window rather than a guaranteed peak date.
- Kew Gardens is a paid attraction, while major Royal Parks such as Greenwich, The Regent’s Park, and St. James’s Park are easy blossom stops during a sightseeing day.
- April weather rewards layers: sunny afternoons can still follow cold mornings or brief showers.
- The Boat Race, Vaisakhi on the Square, and the London Marathon create three significant event weekends in April 2027.
- There is no England and Wales bank holiday during April 2027, because the Easter bank holidays fall in late March that year.
When is blossom season in London in April?
April is one of London’s main spring-flowering months, but there is no single guaranteed day for peak cherry blossom. Kew says its best period for spring flowers is generally from mid-March to mid-April, while Kew’s blossom-viewing guide highlights cherry blossom, magnolias, tulips, bluebells, and daffodils during the wider spring display.
Across the Royal Parks, cherry trees are generally listed as best in bloom from March through April. The exact peak can move earlier or later with winter temperatures, sunshine, wind, and rain, so travelers visiting for flowers should treat blossom as a seasonal window rather than a fixed event.
Cherry blossom is not the only reason to visit London’s parks in April. Daffodils can still be flowering early in the month, while bluebells, tulips, azaleas, and rhododendrons begin adding more color as April progresses.
The Japanese tradition of appreciating blossoms is known as hanami. You do not need a formal event to enjoy it in London: a slow walk or a simple picnic beneath flowering trees can be enough, provided you respect lawns, planted areas, and park rules.
What is the weather like in London during April?
London’s April weather is mild but changeable. The Met Office 1991–2020 climate normals for Heathrow show an average April maximum of 15.0°C (59°F) and minimum of 6.0°C (43°F), which is cooler at night than the original article suggested.
| April weather measure | Heathrow 1991–2020 normal |
|---|---|
| Average maximum temperature | 15.0°C (59°F) |
| Average minimum temperature | 6.0°C (43°F) |
| Monthly rainfall | 42.3 mm |
| Days with at least 1 mm of rain | 8.8 days |
| Monthly sunshine | 176.7 hours |
Those figures are climate averages rather than a forecast for a particular trip. Central London can also feel warmer than more open or suburban locations, especially in sunshine. Check the short-range forecast just before each outdoor day rather than packing only for the monthly average.
Best places to see cherry blossoms in London
The strongest blossom stops combine established cherry trees with other spring planting and easy sightseeing connections. The Royal Parks’ official cherry-tree guide specifically recommends Greenwich Park, St. James’s Park, Kensington Gardens, and The Regent’s Park.
Kew Gardens
Kew Gardens is the best choice if spring plants are one of the main reasons for your trip. Kew identifies the area south of the Palm House, the Japanese Landscape, and the areas outside both ends of the Temperate House as strong places for cherry blossom.
Kew also gives you magnolias and other spring flowers in the same visit, so it works better than a single street or isolated tree if blossom conditions vary. Unlike the Royal Parks, Kew requires paid garden admission; ticket prices and seasonal opening times can change.
Greenwich Park
Greenwich Park combines blossom with one of London’s best elevated city views. For established cherry trees, head toward Ranger’s House beside the Rose Garden and the surrounding avenues in the southwestern part of the park.
The Royal Parks also reports that 130 additional cherry trees were planted along the hillside from Prime Meridian Walk and the Grand Ascent toward One Tree Hill in 2025. Because young trees take time to establish, the older avenues remain the more dependable target for a classic blossom walk.
The Regent’s Park
The Regent’s Park offers several spring displays rather than one isolated blossom spot. Avenue Gardens has clusters of cherry trees along its walkways, while Queen Mary’s Gardens combines additional cherry trees with other seasonal planting.
This is a practical choice if you want a central park walk that can be combined with Marylebone, Baker Street, or Primrose Hill. Cherry blossoms are generally at their best before the famous summer rose display takes over as the park’s main floral attraction.
St. James’s Park
St. James’s Park is the easiest blossom stop to combine with Buckingham Palace and Westminster sightseeing. Look toward Buckingham Palace for cherry trees framing the palace area, or head toward Blue Bridge for blossom with lake views.
Because the park sits on a major tourist route, it can feel busy around midday. An earlier visit gives you more space for photographs and makes it easier to continue toward The Mall, Buckingham Palace, Trafalgar Square, or Westminster afterward.
Best outdoor activities in London during April
April is well suited to walking, parks, riverside sightseeing, and cycling because daylight is increasing without typical summer heat. The main limitation is changing weather, so build days that can switch between outdoor and indoor attractions without crossing the entire city.
- Walk through the Royal Parks: Combine St. James’s Park, Green Park, and Hyde Park for a long central-London route with spring planting and major landmarks.
- Explore the Thames on foot: The South Bank gives you river views plus quick access to indoor attractions if a shower arrives.
- Cycle selectively: A hired bike can work well for parks and river routes, but central streets are not equally comfortable for inexperienced city cyclists.
- Plan a blossom picnic: Greenwich Park, St. James’s Park, and other large parks have room to stop between sightseeing sessions. Avoid blocking paths or stepping into planted beds for photographs.
- Keep one indoor backup: Museums, galleries, covered markets, and historic attractions can rescue an afternoon if a short shower turns into prolonged rain.
Pro Tip: If blossoms are a priority, schedule your main park visit early in the trip. If wind or rain strips petals later in the week, you will already have seen the strongest display available during your stay.
Events happening in London in April 2027
April 2027 has several confirmed events that can affect sightseeing and public transport. The biggest dates are concentrated in the second half of the month, with major activity along the Thames, around Trafalgar Square, and across the London Marathon route.
| Date | Event | What visitors should know |
|---|---|---|
| April 11, 2027 | The CHANEL J12 Boat Race | Oxford and Cambridge race on the 4.2-mile Championship Course between Putney and Mortlake. Expect busy riverbanks and extra foot traffic in west London. |
| April 17, 2027 | Vaisakhi on the Square | A free celebration at Trafalgar Square from 12pm to 6pm, with performances, cultural activities, food, and family programming. |
| April 24–25, 2027 | Double TCS London Marathon | The one-off two-day 2027 format is expected to welcome 100,000 participants. The route runs from Greenwich toward central London, so allow for crowds and road closures. |
St. George’s Day itself falls on April 23 each year, although the date and format of London’s associated public celebration can vary. The 2027 Trafalgar Square festival date had not been officially published when this article was checked.
Travelers should also note that Easter falls unusually early in 2027. According to the official England and Wales bank-holiday calendar, Good Friday is March 26 and Easter Monday is March 29, so there is no nationwide bank holiday in April 2027.
What to pack for London in April
Pack for temperature changes rather than one fixed type of weather. You may want a warmer layer early in the morning, lighter clothing while walking in afternoon sunshine, and waterproof protection if showers develop.
- Light waterproof jacket: More useful than a heavy winter coat on most sightseeing days.
- Layering pieces: T-shirts or shirts with a sweater, cardigan, or light fleece let you adjust through the day.
- Comfortable walking shoes: London trips often involve long distances between stations, parks, museums, markets, and attractions.
- Compact umbrella: Useful for brief showers when wind is not too strong.
- Small day bag: Leave room for a removed layer so you are not carrying a coat by hand all afternoon.
You generally do not need to pack as though London will be wet all day every day. The Met Office normals show measurable rain on roughly nine April days at Heathrow, so a flexible waterproof layer makes more sense than building the whole trip around rain.
How to use public transportation in London in April
London’s Tube, buses, Elizabeth line, London Overground, DLR, and rail network make it possible to see most major attractions without a car. Contactless payment and Oyster are the simplest pay-as-you-go options for many visitors.
Follow Transport for London’s current fare guidance and use the same contactless card or the same device consistently so eligible journeys count toward the correct fare cap. A physical bank card and the same card stored on a phone are treated as different payment methods.
On the Tube and most rail services, touch in at the start and touch out at the end. On London buses, touch in when boarding but do not touch out. If you are traveling across London on routes that avoid Zone 1, a pink reader at some interchange stations can record the route you actually took.
Pro Tip: On April 11 and April 24–25, 2027, check your route before leaving. The Boat Race and London Marathon can concentrate large crowds around specific stations even when the wider transport network is operating normally.
Where to find springtime food in London
Spring is a good time to make London’s markets part of a sightseeing route rather than planning every meal around formal restaurants. Markets let you choose between produce, bakery items, prepared dishes, coffee, desserts, and international street food in one stop.
Borough Market is especially convenient if you are exploring London Bridge, the Thames, or Southwark. Its combination of produce traders, specialist food sellers, and prepared dishes makes it useful for both a quick lunch and browsing ingredients.
Camden Market is better suited to travelers who want a wide mix of casual international food in a busy market setting. It can be combined with Camden Town, Regent’s Canal, and the northern side of The Regent’s Park.
Outdoor markets and fairs to visit in April
April’s longer days make outdoor markets easier to combine with parks and sightseeing. The best choice depends on whether you want food, antiques, independent shops, or a riverside stop.
South Bank
The Southbank Centre Food Market works well with a walk along the Thames. You can combine the market area with the London Eye, Royal Festival Hall, National Theatre, bridges across the Thames, and views toward central London’s landmarks.
Portobello Road Market
Portobello Road in Notting Hill is the stronger choice for antiques, vintage browsing, colorful streets, and market atmosphere. Different types of traders operate on different days, so visit with a broad interest in the neighborhood rather than expecting every category of stall at all times.
Camden Market
Camden combines food, independent retail, and a distinctive streetscape. It is one of the easier markets to make into a longer half-day because Regent’s Canal and The Regent’s Park are both nearby.
Safety tips for visiting London in April
London is a busy major city, so ordinary urban precautions matter more than the month itself. Crowded stations, markets, event routes, and landmark areas deserve extra attention because distraction makes phones, wallets, and bags easier to lose or steal.
- Keep your phone secure when standing near roads, station entrances, or crowded pavements.
- Close bags properly and avoid leaving valuables in an easy-to-reach outer pocket.
- Use well-lit streets and recognized transportation options if you return late at night.
- Leave extra time around major events rather than trying to force your way through dense crowds or closed roads.
- For a serious emergency requiring police, fire, or ambulance assistance in the UK, call 999.
Weather can also create minor practical risks. Wet paving, park paths, and station entrances can become slippery after a shower, so comfortable shoes with reliable grip are more useful than fashion footwear for a full sightseeing day.
