LE SSERAFIM PUREFLOW World Tour: Dates, Tickets & Venue (London)

One night under the tent

The date is Friday 16 October 2026. LE SSERAFIM bring their PUREFLOW World Tour to The O2, and it is the five-piece’s first headline concert in London. Chaewon, Sakura, Yunjin, Kazuha and Eunchae have played festivals and promo slots abroad before. A full arena show of their own in the UK capital is new.

The O2 is the white fabric dome held up by twelve yellow masts on the Greenwich Peninsula. The arena inside seats around 20,000. It sits within a wider covered street of restaurants and bars, so the hours before a show play out indoors whatever the October weather.

Getting to North Greenwich

The Jubilee line is how most of the crowd arrives. North Greenwich station opens straight onto the plaza in front of the dome, a two-minute walk to the entrances. Canary Wharf is one stop away and London Bridge four, so central hotels connect easily.

Other routes onto the peninsula:

• Uber Boat by Thames Clippers to North Greenwich Pier, a scenic run from Westminster, Embankment or London Bridge
• IFS Cloud Cable Car across the river from Royal Victoria on the DLR
• Buses 188 and 108 from the bus station under the dome’s forecourt
• Driving to the paid on-site car parks, though post-show traffic out of the peninsula moves slowly

After the encore, the Jubilee line platform is managed with queue barriers outside the station. Many fans walk to the pier or take the bus to skip the crush.

How FEARNOT fill an arena

The crowd usually arrives hours before the music. At K-pop arena shows in London, the official merchandise queue often forms well before doors. Fans trade freebies outside: photocards, stickers and hand-made banners, usually swapped in the plaza.

Inside, these are the things people tend to bring:

• The official LE SSERAFIM light stick, fully charged
• A small bag only, since The O2 runs a bag policy at its entrances
• A phone with contactless payment, which is how most fans pay at the bars and stalls
• A printed or memorised fan-chant guide for the title tracks

The fan chants matter. FEARNOT shout the members’ names in a fixed order during song intros, and London crowds learn them. Standing-floor ticket holders usually queue in numbered order before doors open. Seated tiers fill more gradually.

Before and after the show

The dome itself gives you somewhere to wait. Inside the covered street are chain restaurants and bars, and the Icon Outlet shopping centre sits under the same roof. On the outside, Up at The O2 runs guided climbs over the dome’s canvas roof.

Greenwich proper is a short bus or boat hop west. The Cutty Sark, the Old Royal Naval College and Greenwich Park with the Royal Observatory are all there, which makes for an easy daytime itinerary on show day.

Canary Wharf, one Jubilee stop away, has the closest cluster of large hotels. Fans travelling from outside London often stay there for a short ride back after the curfew. The organiser publishes the tour dates, the venue and ticket links on its official site.
