What's On in Cardiff
Sunday 20 September 2026 · This weekend · City guide
Cardiff is shaking off any last traces of a lazy Sunday lie-in this 20th of September, with a day that stretches gloriously from vintage fashion hauls in the afternoon all the way through to late-night freshers chaos in the small hours. Whether you are hunting for a pre-loved bargain, craving a night of sharp comedy, or ready to throw yourself headfirst into the new academic year, the city has something with your name on it.
Highlights
Fashion Thrift Society Cardiff | September 20th — Depot Cardiff becomes a treasure hunter's paradise as Fashion Thrift Society takes over for a full afternoon of pre-loved fashion, with timed entry slots running from 11:00am through to 4:00pm so you can browse without the scrum. Think rails packed with everything from vintage denim to barely-worn designer pieces, all at prices that will make your Sunday very smug indeed. Whether you are a seasoned thrifter or a curious newcomer, this is the kind of event that turns a casual browse into a proper haul — book your slot on the website and go hungry for a find.

Mike Wozniak: The Bench — The gloriously deadpan Mike Wozniak — beloved from Taskmaster and his own singular brand of absurdist storytelling — brings his new show to New Theatre Cardiff at 7:30pm, and if you have ever seen him work a room you will already know to get your ticket fast. The Bench promises the kind of meticulously crafted, quietly ridiculous comedy that creeps up on you and then absolutely floors you when you least expect it. New Theatre is a stunning Victorian venue that gives the whole evening a proper occasion feel — dress up, go early, and let yourself be utterly baffled in the best possible way. Check website for prices.
Bratakus — Fuel Rock Club is one of Cardiff's most reliably electric live music venues, and Bratakus hit the stage at 7:30pm for what promises to be a ferociously energetic evening in its sweaty, atmospheric basement setting. Bratakus are a force of nature live — the kind of band that leaves you wondering why you do not go to more gigs on a Sunday night. Check the website for ticket prices and do not say you were not warned about the noise levels.

The Official Cardiff Freshers Wristband 2026 — Cardiff City Centre transforms into one enormous welcome party from 10:00pm as thousands of new students descend on the city for what is arguably the biggest night of the freshers calendar. One wristband, priced at £20–£40, unlocks multiple venues across the city centre, meaning you can roam freely and find your crowd — or make an entirely new one. Even if you are not freshly enrolled anywhere, the energy of this night is genuinely infectious, and Cardiff does this sort of thing with more warmth and chaos than almost any other city in the UK.
