September is one of my favorite months to visit London. The weather is comfortable for walking, and family crowds thin out once British schools reopen. I prefer September to August for most adult visitors. The main drawback is price. Business travel and major events keep central London hotels expensive, particularly midweek. Open House Festival and London Design Festival are two of the city’s best annual events, and Buckingham Palace’s State Rooms are usually open for much of the month.
London in September: At a Glance
- Weather: Mild and changeable. Average daytime highs around 19°C (66°F), with cooler mornings and evenings.
- Crowds: London remains busy, but family attractions are generally quieter on weekdays after schools reopen.
- Hotel Prices: High, particularly during major business events and conferences.
- Daylight: Sunset is around 7:45 PM at the beginning of September and 6:40 PM at the end.
- Best Events: Open House Festival, London Design Festival, and Buckingham Palace’s summer opening.
- Best Activities: Walking, parks, Thames boat trips, theater, and architecture tours.

Quick Hotel Picks for September
- Best for First-Time Visitors: Kimpton Fitzroy London in Bloomsbury, near the British Museum and Russell Square station.
- Best for Theater: NoMad London in Covent Garden, within walking distance of West End theaters, Soho, and Trafalgar Square.
- Best Classic Luxury Hotel: The Savoy, between Covent Garden and the Thames.
- Best for Eurostar: St. Pancras Renaissance Hotel, in the historic St Pancras station building. A luxury choice rather than a budget option.
- Best for Families: Park Plaza Westminster Bridge, with family rooms, an indoor pool, and a convenient South Bank location.
- Best Value: Motel One Tower Hill, near the Tower of London and Tower Hill station, usually less expensive than comparable hotels in the West End.
London Weather in September
September is mild rather than hot. Average daytime highs are around 19°C (66°F), with nighttime temperatures near 11°C (52°F). Days above 20°C (68°F) are common early in the month, while late September brings cooler mornings and evenings. Rain is possible throughout the month, but a forecast showing showers rarely means an entire day will be wet. By the end of September, sunset is around 6:40 PM, and the best autumn color is still a few weeks away.
What to Pack
- Light layers: A shirt or T-shirt under a sweater handles most temperature changes.
- Waterproof jacket: Choose one light enough to carry when the weather clears.
- Comfortable walking shoes: You’ll probably spend several hours a day on foot.
- Compact umbrella: Useful for short showers, though a hooded jacket is better in windy weather.
Best Things to Do in London in September
Explore Open House Festival
Open House Festival gives visitors access to private interiors, government buildings, homes, studios, infrastructure sites, and architecture tours across London. Many events are free, but popular buildings require advance booking, timed entry, or a ballot. Check the program when it is released rather than waiting until you arrive. I particularly like the smaller tours of modern homes, transport infrastructure, and buildings that are normally closed to the public.
See London Design Festival
The Victoria and Albert Museum is traditionally a major hub for London Design Festival, with exhibitions and installations in design districts across the city. Check the current program and choose one district to explore. Crossing London repeatedly to see isolated installations wastes too much time.
Tour Buckingham Palace
September is usually the final month of the Buckingham Palace State Rooms summer opening. Exact dates change each year, so check the opening calendar before booking your trip. Allow at least two hours for the visit. Combine the palace with St. James’s Park, Green Park, or a walk through Mayfair.
Take a Thames Boat to Greenwich
Take a boat from Westminster or the London Eye to Greenwich, passing Tate Modern, Tower Bridge, Canary Wharf, and views of St Paul’s Cathedral along the way. Sit outside if the weather is dry, but bring an extra layer for the river breeze. Allow at least half a day in Greenwich for the Old Royal Naval College, Greenwich Market, and Greenwich Park. Add the National Maritime Museum if you have more time. I’d take the boat in at least one direction rather than using the Tube both ways.
Walk Through London’s Parks
Regent’s Park and Primrose Hill combine easily in half a day, with excellent skyline views from the hill. Hampstead Heath is better for longer walks and less manicured scenery. Richmond Park is farther from central London but worth the journey if you have time, particularly for its deer and wide-open spaces. September is generally too early for strong autumn foliage, but the cooler weather is ideal for walking.
See a West End Show
New autumn productions and limited engagements begin appearing in September alongside London’s long-running musicals. If you’re flexible about what to see, weekday performances and same-day tickets can offer better value. The official TKTS booth in Leicester Square is a good place to look for discounted seats.
Walk the South Bank at Sunset
Start near Westminster Bridge and walk east past the London Eye, Royal Festival Hall, National Theatre, Tate Modern, Shakespeare’s Globe, and Borough Market. Continue along the river to Tower Bridge. The walk takes about 60 to 75 minutes without stops, but allow two hours if you want to explore along the way. In late September, start around 5 PM to catch the last of the daylight.
What to Book Ahead
- Buckingham Palace State Rooms: Book once your travel dates are fixed, especially for weekends and the final days of the summer opening.
- Open House Festival: Reserve limited-entry buildings and tours as soon as booking opens. Some popular events use ballots.
- Popular West End Shows: Book several weeks ahead for headline productions and weekend performances. Flexible travelers can look for last-minute deals.
- Warner Bros. Studio Tour: Reserve well in advance, often months ahead for popular dates. Don’t expect to buy tickets on arrival.
- Special Museum Exhibitions: Major exhibitions at the British Museum, National Gallery, Tate, and Victoria and Albert Museum may require timed tickets.
For major attractions such as Westminster Abbey and the Tower of London, I recommend booking an early entry time. They can be crowded even after the summer school holidays end.
Where to Stay in London in September
September hotel prices can be surprisingly high, especially during major conferences and business events. Check rates for your exact dates before settling on a neighborhood. Midweek stays in business-oriented areas can be expensive, while weekends sometimes offer better value. See my guide to the best places to stay in London and the London hotel map.
Covent Garden: Best for First-Time Visitors
Covent Garden puts the West End, Trafalgar Square, Soho, the National Gallery, and the South Bank within easy walking distance. NoMad London is one of the area’s best luxury hotels. The drawback is heavy foot traffic, with some streets noisy late into the evening.
Bloomsbury: Best for Museums and a Quieter Center
Bloomsbury is quieter than Covent Garden but still central, with the British Museum, Russell Square, and good transport connections. Kimpton Fitzroy London overlooks Russell Square, with direct Piccadilly line service to Heathrow from the nearby station. Covent Garden is better for nightlife and theaters.
South Bank: Best for Families
The South Bank gives families easy access to the London Eye, SEA LIFE London Aquarium, Westminster, Tate Modern, and river cruises. The riverside path is mostly level and works well with strollers. Park Plaza Westminster Bridge has family rooms and an indoor pool. The area around Westminster Bridge gets extremely crowded, so don’t expect a quiet neighborhood.
King’s Cross and St Pancras: Best for Eurostar
King’s Cross and St Pancras are convenient for Eurostar arrivals and trains to northern England. Granary Square and Coal Drops Yard have good restaurants, bars, and public spaces. St. Pancras Renaissance Hotel occupies the historic station building. It’s a luxury hotel, and you’re paying for the architecture and location as much as the convenience. The area is less useful if most of your sightseeing is around Westminster and the South Bank.
The Strand: Best Classic Luxury Location
The Strand sits between Covent Garden, Trafalgar Square, and the Thames, within walking distance of major theaters and restaurants. The Savoy is the standout luxury hotel. Traffic and high room rates are the main drawbacks.
Tower Hill: Best Value in Central London
Tower Hill offers easy access to the Tower of London, Tower Bridge, the City, and Thames river services. Motel One Tower Hill is close to Tower Hill and Aldgate stations, with comfortable rooms and typically lower rates than similar hotels in Covent Garden or Soho. The area is less lively at night than the West End, though St Katharine Docks and nearby riverside restaurants offer good evening options.
London in September vs August and October
- August: Warmer, longer days, and more families visiting during school holidays. Best if you’re tied to summer vacation dates.
- September: My choice for most adult visitors. Comfortable weather, fewer school-holiday crowds, and excellent architecture and design events. Hotels can be expensive.
- October: Cooler, shorter days, and better autumn color, particularly in the second half of the month. September is better for long sightseeing days.
