In this guide
September is the month London stops performing for visitors and goes back to being a working city — and it is, for that reason, one of the two or three best months to be here.
The schools go back in the first week. From around the 5th, the museums thin out, restaurant tables reappear and the South Bank stops being an obstacle course, while the weather usually holds well into the month. Sunset is still after seven for the first three weeks. It is August’s weather with October’s crowds.
Then the middle of the month does something remarkable, and no published guide seems to say it plainly.
Open House and the London Design Festival run the same nine days. In 2026 that is 12 to 20 September, exactly. Heritage Open Days overlaps them, 11 to 20. London Fashion Week starts the day before they finish. For anyone interested in buildings, design or how London is put together, that week is the best week of the year to be in the city — and it is simultaneously the worst week to want a cheap hotel room or a quiet gallery. Both halves of that are worth knowing before you book.
The one that will define the year
The Bayeux Tapestry — British Museum, from 10 September
Room 30, the Sainsbury Exhibitions Gallery · 10 September 2026 to 11 July 2027
For the first time in nearly a thousand years, the Bayeux Tapestry is in England. Not a reproduction and not a section of it: the seventy-metre embroidery itself, on loan from France under a government-level agreement, telling the story of the events leading to the Battle of Hastings and the Norman Conquest.
The thing worth understanding about it is the collaboration buried in its making. It was likely commissioned by a Norman patron but embroidered by English hands, working from manuscript drawings out of Canterbury — so the account of England’s conquest was stitched by the conquered, and it is as much a record of eleventh-century life as of a battle. Castles, ships, warfare, but also clothing, food and furniture.
Opening hours are unusually long, and that is the tactical detail. Sunday to Wednesday it runs 10am to 6pm; Thursday to Saturday it stays open until 9pm. Late Thursday and Friday slots are the civilised way to see it.
Tickets: this is the part to plan. The current release has largely gone. Members’ priority booking reopens on 6 October 2026, and the next general ticket release is 21 October 2026, covering visits from 1 January to 31 March 2027. If you want to go and have not booked, those are the two dates that matter — the British Museum’s newsletter is the only reliable way to be told when releases open.
If you cannot get in, Bayeux Around Britain runs related programmes at more than sixty museums and heritage sites across the country. There is also a curator’s talk, The real world of the Bayeux Tapestry, online on 25 September, £50.
The annual fixtures
These come round every year. If you are reading this in a later September, the dates will have moved but the events will be here.
Totally Thames — the whole month, the whole river
1 to 30 September, every year, along the length of the tidal Thames.
A month-long river festival run by the Thames Festival Trust, and much the most underrated thing in this guide because it does not present as a single event you can turn up to. It is dispersed by design: art installations, boat trips, river races, environmental projects and — the ones worth planning around — foreshore archaeology walks, where you go down onto the exposed riverbed at low tide with someone who can tell you what you are looking at.
A large share of it is free. The foreshore walks are the exception in demand rather than price, and they book out early, because the number of people who can safely stand on a tidal foreshore is small and the tide decides the timings rather than the organisers.
If you only take one thing from this page: the Thames is the reason London is here, and September is the one month the city organises itself around saying so.
The Great River Race — 21.6 miles, 300 boats, mostly in fancy dress
Saturday 12 September 2026, first boats crossing the start line at 12.45pm.
London’s river marathon, and a genuinely strange and wonderful thing to stumble on. Around 300 fixed-seat crews row 21.6 miles from Millwall in the east to Ham in the west, under every bridge in between. It started in 1988 with 61 boats and is now international, with crews from America, Australia and across Europe — and a large part of the field is raising money in fancy dress, so the serious athletes are threaded through a flotilla of nonsense.
It is free to watch and you do not need a plan. Stand on any bridge or bank and it will come past; the organiser publishes an observation points page giving rough times along the course. The finish at Ham has food, a bar and a disco. There is also a supporters’ boat from Millwall to Ham, which is bookable.
One warning worth carrying: the start time moves with the tide and is confirmed late, so never assume last year’s. And the event’s site is greatriverrace.org.uk — the old .co.uk address is now a parked domain with a for-sale banner and nothing to do with the race.
Open House Festival — the free one everybody misses by a week
12 to 20 September 2026. Free.
Open City opens buildings across every London borough that are normally shut, private or expensive: livery halls, private houses, government buildings, infrastructure, and architects’ own homes, which are consistently the most interesting category and the least contested.
The catch is not money, it is timing, and this is where most people go wrong. The programme goes live in August. The buildings everyone wants — the ones that appear in the newspaper write-ups — either run a ballot or release timed slots that are gone within hours. By September the marquee list has been taken.
That is not a reason to skip it. Hundreds of buildings are walk-up, no booking, just a queue and a volunteer at the door, and they are frequently better than the famous ones because you can take your time. The move is to ignore the towers, pick a neighbourhood, and walk it. Then set a reminder for the programme launch next August.
Heritage Open Days — the one people confuse with Open House
11 to 20 September 2026. Free.
A different organisation, running at the same time, and readers conflate the two constantly. Heritage Open Days is England’s largest festival of history and culture, volunteer-organised and national rather than London-only, and it skews to heritage where Open House skews to architecture — so churches, halls, historic trades and local history, alongside the buildings.
If you are in London that week you can treat them as one programme with two websites. Check both; the overlap is smaller than you would expect.
London Design Festival — nine days, and mostly free
12 to 20 September 2026.
Built on design districts — Brompton, Shoreditch, Mayfair, Bankside and others — each with its own trail, plus large commissioned installations in public spaces and at the V&A, which has been the festival’s traditional hub for years.
Most of it is free and unticketed, which is the part people do not realise: the installations are simply in the city, and you can walk into them. The Global Design Forum and the talks programme are ticketed and do sell out.
Because it runs the same nine days as Open House, the sensible approach is to treat them as a single week rather than choose. One gets you inside buildings; the other tells you what people are doing with the insides of buildings.
Last Night of the Proms — and how to actually get in
Saturday 12 September 2026, 7.15pm, doors 5.45pm, Royal Albert Hall.
The close of a summer of more than eighty concerts. In 2026 it is Yuja Wang on piano, returning after her 2023 appearance, with Scottish tenor Nicky Spence and the massed BBC forces under Sakari Oramo.
Seats are long gone, and that is where almost every guide stops. Day Promming tickets go on sale at 9.30am on the day of the concert, two per booker — standing, in the arena or the gallery, and the cheapest way into the most oversubscribed classical concert in the country. Season ticket holders redeem theirs from 11am the day before.
If you want the experience without the queue, the Proms in the Park tradition has changed in recent years; check the BBC’s own listing for what is running before making plans around it.
London Fashion Week — and what it actually means for you
Thursday 17 to Monday 21 September 2026.
Worth including mainly to correct a misunderstanding. This is not a public event. The September edition shows the following spring and summer, it is run by the British Fashion Council, and the shows themselves are trade and press only.
What it means for a visitor is threefold: a schedule of open events and shopping activations around the main programme; a noticeably busier central London; and hotel rates through that weekend that are the highest of the month. If you are choosing dates and do not care about fashion, book either side of it.
Exhibitions closing this month
The most time-sensitive thing in this guide, and the reason to read it now rather than in October.
Monet and Renoir: Painting Side by Side — National Gallery, closes 15 September
The urgent one, and it is free.
In the summer of 1869 Monet and Renoir — young, broke and close friends — set up their easels beside each other at La Grenouillère, a riverside resort outside Paris, and painted the same scene of Parisians at leisure. The National Gallery has reunited the two resulting paintings for the first time in nearly twenty years, with Renoir’s canvas on loan from the Nationalmuseum in Stockholm.
Two pictures, one room. The entire point is standing in front of them together and seeing two painters make completely different things from an identical view — which is exactly what reproductions cannot do, and why it is worth a specific trip rather than a browse.
Room 41, free, no booking. It closes on 15 September, after which Renoir’s painting moves into the Gallery’s Renoir and Love exhibition, which opens on 3 October — so the pairing goes, even though the picture stays in the building.
Also closing at the National Gallery on 20 September is Waldmüller: Landscapes, the Austrian painter’s studies of the countryside around Vienna — quieter, and you will have it largely to yourself while everyone queues down the corridor.
Early Netherlandish drawings — British Museum, closes 20 September
Free, Room 90, daily 10am to 5pm, and the museum’s own listing has already marked it “Final weeks”.
Around 120 drawings from the Low Countries before 1600 — Rogier van der Weyden, Lucas van Leyden, Pieter Bruegel the Elder and Hendrick Goltzius — tracing the moment drawings stopped being preparatory studies and became works in their own right.
The reason to go now rather than intend to go: early Netherlandish drawings are extremely rare, because they were made as functional workshop objects and were not meant to survive. And works on paper can only be exhibited for short periods because light damages them permanently — so when this closes, these sheets go back into storage for years rather than months. The British Museum’s own holdings are what make a survey on this scale possible at all, and it is unlikely to be repeated soon.
James McNeill Whistler — Tate Britain, closes 27 September
The month’s biggest closing show, with three weeks left, and the first major European Whistler exhibition in thirty years.
A full retrospective of the American who spent his career in London: the famous paintings alongside works rarely or never shown, running from his teens in St Petersburg through to the enigmatic late self-portraits, and taking in portraits, drawings, prints and designs. The Nocturnes are the reason most people come — Old Battersea Bridge among them — and they are the paintings that got him into a libel court arguing that a picture need not be a picture of anything.
Ticketed, and free for Tate Members, which pays for itself quickly if you are going to two or more shows this autumn. Book ahead for a weekend — this is the one exhibition on this list where turning up on spec in the final fortnight is likely to fail.
Exhibitions worth the trip
Running through September and beyond, so no rush — but these are the good ones.
BBC TV 90 at Alexandra Palace, 18 September to 30 November, is the pick. BBC television began at Ally Pally in 1936, so a ninetieth-anniversary exhibition there is on the actual site rather than merely about it — the transmitter mast is still on the roof.
John Constable: views of nature at the British Museum runs to 4 October and is free. Frida: The Making of an Icon at Tate Modern runs to 3 January, so it will keep. The Serpentine Pavilion is in Kensington Gardens until 25 October, also free, and September is the last month it is reliably pleasant to sit in one. Richard Dadd at the Royal Academy runs to 25 October. Open Roots opens at the Photographers’ Gallery on 18 September.
Theatre: the autumn openings
September is when the West End restarts. The summer run ends, Kids Week is over, and the autumn press nights come in a cluster — which means an unusual concentration of opening nights and, for a few weeks, previews at preview prices.
The first week brings Bloodsport: After Helen of Troy at Theatre Royal Stratford East on the 3rd — Ava Pickett’s follow-up to 1536, with Michelle Dockery and Laura Aikman, and Lisa Spirling directing. The same night, Thelma & Louise opens at the Young Vic as a new musical, with Amy Lennox and Rachel Tucker. Million Dollar Quartet follows on the 4th at the Arts at Marble Arch.
The one to book is on the 5th: Tilda Swinton in Man to Man at the Royal Court, returning after more than thirty years to the role that made her name — Manfred Karge’s play about a woman who takes on her dead husband’s identity to survive in 1930s Germany.
The second half of the month is heavier still. Jesse Tyler Ferguson plays Truman Capote in Tru at the Menier Chocolate Factory from the 19th. Gillian Anderson and Billy Crudup open in Who’s Afraid of Virginia Woolf? at @sohoplace on the 21st, directed by Marianne Elliott. The same evening, James Graham’s The Standard of Living opens at the Theatre Royal Haymarket, with Rory Kinnear as John Maynard Keynes. Then on the 22nd: Christine Baranski and Richard E. Grant in Hay Fever at Wyndham’s, Into the Woods at the Noel Coward, and RENT returning to Drury Lane for its thirtieth anniversary.
One piece of housekeeping that will date any older guide you read: the Duke of York’s Theatre is now the Tom Stoppard Theatre.
Gigs worth planning around
Not a listings page — Songkick and DICE do that better. These are the shows worth building an evening around, and this month one of them is a building.
Blue Note London opens — St Martin’s Lane, from 23 September
Covent Garden · WC2N 4EJ
The legendary New York jazz club opens its first UK venue, on St Martin’s Lane, joining a group that already runs rooms in New York, Los Angeles, Tokyo and Milan. It is the most consequential music opening London has had in years, and it is happening this month.
The layout is the part worth knowing. There are two rooms: a 300-seat main room, and B-Side, a 130-seat space for late sets, emerging artists and one-offs. That means two shows a night, every night — so a sold-out headliner does not close the building, and the B-Side programme is where the interesting risks will be taken. There is a full kitchen and a bar, with a cocktail list built on reimagined jazz-era classics.
The grand opening on 23 September is Robert Glasper, two shows at 7pm and 9.30pm, and it has sold out. The rest of the opening run has not: Sinead Harnett on the 25th, corto.alto on the 26th, Yussef Dayes on the 27th, and Jamie Cullum across the 28th and 29th, with Nik West carrying it into October.
Look further ahead before you book anything, because the October diary is extraordinary for a room that will be three weeks old: Erykah Badu on the 10th and 11th, Baaba Maal, Nubya Garcia across the 15th to 17th, and Shabaka on the 19th and 20th. If you are choosing a night, choose on the programme rather than the novelty.
Saint Etienne at the Roundhouse on 18 September is the one to take seriously if you have any history with the band. Also at the Roundhouse: Bellaire, Dublon and Jeremy Underground on the 12th, and Good Kid with Last Dinosaurs on the 26th.
Alexandra Palace has the busiest month of any venue in London. Annie Mac on the 12th, ANOTR across the 17th and 18th, Boris Brejcha on the 19th, I Prevail on the 25th and Public Service Broadcasting on the 26th — the last of which, in a hall that is also the birthplace of television, is a better fit than the band could have designed.
For something entirely different, the Monteverdi Choir performs Rossini’s Petite Messe Solennelle at Ally Pally on 18 September.
New restaurants and bars
September is the opening rush — the trade holds its launches back through August and then releases them all at once. This is the most perishable section on the page; everything below opened in the first ten days of the month.
Nakimushi in Notting Hill (7 Kensington Mall, W8 4DY) is the one generating most noise. From the Dorian team, in a townhouse, bringing together Yuji Shimokawa Kelly of Urchin and Robin Kosuge of Robin’s Ramen — a ramen bar downstairs and a broader Japanese menu above, with dishes like red prawn and courgette gyoza with umeboshi.
In the City, The Albatross (8–10 Old Jewry, EC2R 8DN) is the Goodman and Wild group’s first proper pub, with Chris Dunlop, previously of New York’s The Spotted Pig, brought in as landlord to get the pub part right. The food is seafood-led — lobster thermidor, bisque, oyster platters.
Cordelia’s in Mayfair (6 Clarges Street, W1J 8AE) is a steakhouse in the old Joël Robuchon space, built round a charcoal bar, with British cuts alongside Galician and Parmesan-fed Italian beef. Beefbar has taken over Dear Jackie inside Broadwick Soho, keeping the name and the downstairs decor. Le Cafe LPM has opened inside the Lanesborough at Hyde Park Corner as a twelve-month residency, terrace included.
Further out, Marrion’s on Morning Lane in Hackney is a neighbourhood bar from the man behind Norman’s — classic cocktails, Spanish beer, devilled crab rarebit. Pardeh in Bethnal Green is Persian; Pino in Stoke Newington is Puglian, with riso, patate e cozze on the menu.
Three more worth watching: Romy Gill has taken over The Pem in St James’s and turned it to regional Indian cooking; Endo Kazutoshi has opened his ENDO omakase room in Chelsea with a Moga listening bar above it; and the Savoy’s Beaufort Bar has become a wine bar, complete with a bespoke charcuterie trolley. The Mr Fogg’s team are opening The Admiral’s Mess inside Admiralty Arch, where Clare Smyth and Daniel Boulud are also arriving.
Practical: September in London
Weather. Typically 19–21°C by day, 12–13°C at night, cooling through the month, and historically one of the drier ones. The thing to plan for is the gap between afternoon and evening: take a jacket even when the day is warm.
Daylight. Sunset moves from roughly 7.30pm on the 1st to about 6.45pm on the 30th, with the equinox around the 22nd. The last genuinely good evenings for river walks, roof terraces and outdoor tables are in the first three weeks.
Crowds. The best argument for September. Schools return in the first week and the difference is immediate — from about the 5th, the big museums, the major attractions and the restaurants that never have tables all become manageable.
Prices. Hotel rates fall from the August peak in the first week, then climb sharply for the middle stretch when Open House, the Design Festival and Fashion Week land on top of each other. If you are flexible, the first week and the last week of September are the value in this month.
Common questions
What is the best time to visit London in September?
The first week if you want the city quiet and cheap, the middle if you want the most to do. Schools go back in the first few days, so from around the 5th the museums and restaurants ease off sharply while the weather still holds. The middle of the month is the opposite trade: Open House, the London Design Festival and Heritage Open Days all overlap, and London Fashion Week follows immediately, so there is more on than at any other point in the year and hotel rates rise to match.
When can I get tickets for the Bayeux Tapestry at the British Museum?
The next general ticket release is 21 October 2026, covering visits between 1 January and 31 March 2027. Members' priority booking reopens earlier, on 6 October 2026. The exhibition itself opened on 10 September 2026 and runs until 11 July 2027 in Room 30, and earlier releases have gone quickly — the museum's newsletter is the only dependable way to hear when the next one opens. Worth knowing that it stays open until 9pm from Thursday to Saturday, so late slots are the calmest.
What events are on in London in September 2026?
Totally Thames runs the whole month along the river. Open House and the London Design Festival both run 12 to 20 September, Heritage Open Days 11 to 20, and London Fashion Week 17 to 21. Saturday 12 September is the busiest single day of the month: the Great River Race rows 21.6 miles from Millwall to Ham from 12.45pm, and the Last Night of the Proms closes the season at the Royal Albert Hall at 7.15pm.
Is Open House London free?
Yes, entirely. The catch is not money but timing — the programme goes live in August, and the buildings people most want to see either ballot or release timed slots that go within hours of opening. If you are deciding in September, the marquee buildings have gone. Plan around the walk-up sites instead, of which there are hundreds, and set a reminder for the programme launch next August.
Can you still get tickets for the Last Night of the Proms?
Seats sell out far in advance, but the hall is not closed to you. Day Promming tickets — standing, in the arena or the gallery — go on sale at 9.30am on the day of the concert, two per person. Season ticket holders can redeem from 11am the day before. It is the cheapest way into the most oversubscribed classical concert in Britain and almost no guide mentions it.
What exhibitions are closing in London in September 2026?
Four worth catching. Monet and Renoir: Painting Side by Side at the National Gallery closes on 15 September. Early Netherlandish drawings at the British Museum and Waldmüller: Landscapes at the National Gallery both close on 20 September. James McNeill Whistler at Tate Britain closes on 27 September.
What is the weather like in London in September?
Usually 19 to 21°C by day and around 12 to 13°C at night, cooling noticeably through the month, and historically one of the drier months. The practical point is that afternoons stay warm while evenings stop being reliable — take a jacket even on a hot day. Sunset moves from about 7.30pm at the start of the month to about 6.45pm by the end, so the last genuinely good evenings for river walks and outdoor drinking are the first three weeks.
