Cardiff has quietly become a serious outdoor concert city. Two separate series run through the summer — Blackweir Live on Blackweir Fields in Bute Park, and Depot Live inside the walls of Cardiff Castle — and between them they now account for a large share of the city's live music in June, July and August.
Both are confirmed to return in 2027. Neither has announced a line-up yet.
2026 was Blackweir Live's second year and drew around 175,000 people across five nights, with The Cure, Teddy Swims, two nights of Lewis Capaldi and Pitbull. It is run by Depot Live together with Cuffe and Taylor.
The site is a large open field in Bute Park, immediately north of Cardiff Castle, which means the whole city centre is walkable afterwards — a real advantage over out-of-town festival sites.
The Cardiff Castle series had its biggest year in 2026: 24 nights and more than 80 artists across June to August, including Katy Perry, Biffy Clyro, Bastille, McFly, Richard Ashcroft and The Streets.
Playing inside a castle in the middle of a capital city is the selling point, and the capacity is smaller than Blackweir, so shows tend to sell faster.
Based on the last two cycles, first headliner announcements land between November and February, with tickets on sale within days of each announcement. Depot Live has already said it will be back in 2027.
If you want to be ready rather than reactive, the practical move is to know which pre-sale you need before the announcement rather than after — most on-sales for these shows are effectively decided in the first hour.
The summer series get the headliners, but Cardiff's year-round circuit is what makes it a music city rather than a stop on a tour. Clwb Ifor Bach on Womanby Street is the institution — three floors, Welsh-language roots, and the venue that anchored the campaign that saved the street from redevelopment. Tramshed in Grangetown takes the mid-size touring shows, and the Students' Union hosts a steady run of bigger indie and rock bookings through term time.
Utilita Arena Cardiff covers the arena tier with something on most weeks, and the Principality Stadium takes the handful of shows a year that outgrow everything else. Between them the city rarely has a quiet week outside January.
Both sites are walkable from Cardiff Central, which changes the calculation on getting home: unlike a greenfield festival, you are in the city centre the moment you leave.
Both are outdoor and go ahead in rain. Cardiff in July is warm but genuinely wet — the sensible packing list is a lightweight waterproof rather than an umbrella, which most sites will not let you bring in.
Bag policies apply at both and tend to tighten each year, so check the size limit for your show before travelling. Neither site has left luggage, and the nearest lockers are at Cardiff Central.
Yes, it is confirmed to return to Bute Park. The line-up has not been announced — in previous years first headliners were revealed between November and February.
Blackweir Fields in Bute Park, Cardiff, just north of Cardiff Castle and walkable from the city centre and Cardiff Central station.
No, they are separate series, though Depot Live is involved in both. Cardiff Castle shows are inside the castle grounds and have a smaller capacity; Blackweir Live is a large open field in Bute Park.
