Cardiff comes alive in the summer. Concerts, food festivals, Melas, and Rhiwbina – there seems to always be something on! And that's before you even get to your regular nights out at Cardiff’s best and finest pubs and clubs. There’s so much on, in fact, that it can be hard to know what to do, whether you're a local or you're planning a weekend visit.
So, to make your Cardiff summer shine, we've rounded up some of the best outdoor and indoor events worth checking out between June and September.

Making the Most of Cardiff This Summer
Soak Up the Atmosphere at Cardiff's Outdoor Festivals
Summer and festivals go hand in hand, and Cardiff delivers plenty of options. There are family festivals, food festivals, beer festivals, and rock festivals. There’s Vintage for Victory and the Blackbird Festival. Whatever floats your summer boat, you’ll find it in Cardiff, with the Bay and Bute Park buzzing with entertainment, food, drink, and the entirely unexpected. So, get ready to stuff your face and dance in the sunshine… Just don’t forget your raincoat. This is Wales, after all.
Catch a Gig at Cardiff Castle
Few venues can compete with the atmosphere of Cardiff Castle, whatever the weather. And every summer, some of the biggest names in music take to the stage within the castle walls. We guarantee it's one of the most unique concert experiences you’ll have in the UK.
The lineup changes every year, but the atmosphere is always electric. So, if you're a music fan, this is one summer venue you just won’t want to miss.
Explore Cardiff Bay
Cardiff Bay! We’ve yet to meet a person who doesn’t love Cardiff Bay. It is one of the best places in the city to spend a sunny afternoon.
You can take a stroll along the waterfront, grab a drink overlooking the water, or simply enjoy watching the world go by. But as well as the restaurants, bars, and attractions, the Bay is usually host to a whole range of summer events, so you’ll surely find plenty to keep you busy. Not to mention a bucketful of backdrops for those must-have Insta photos!
Escape the Weather with Indoor Entertainment
OK, so, the UK isn’t known for reliably sunny summers. And Wales has to be among the worst for surprise showers and soakings. So, you need a backup in case the weather isn’t playing ball. That’s why Cardiff has plenty of indoor entertainment options too.
From comedy shows and live theatre performances to immersive experiences and late-night bars, there's always something happening under cover for those last-minute backup plans.
