There’s nothing worse than having the day off to spend with family or friends, and it is pouring down with rain. The Welsh weather is not often on our side, but don’t let the wet weather dampen your day. Luckily, there are plenty of different things to do in Cardiff on a rainy day.

What to do in South Wales when it’s raining? Cardiff has the unofficial title of ‘the UK’s wettest city.’ In fact, on average, it rains 180 days of the year! If you’re stuck on what to do on a rainy day or want to try a new activity, hopefully, this list can offer some inspiration.
Visit the museum
We are lucky to have free museums in Cardiff, which are some of the best in Britain. The National Museum Cardiff has everything from dinosaurs to art galleries. Or there’s the Cardiff Story Museum which showcases how the city has changed and the people who have made it. Don’t forget to get your key to Cardiff Castle and discover the Firing Line Museum, the keep, the clocktower and the castle itself.
Immerse yourself in local heritage
The gardens at Insole Court in Llandaff are a peaceful quiet walk. However, one of the things to do in Cardiff on a rainy day is to experience the Grade II listed mansion house. It has undergone extensive refurbishments. Over the first floor is an exhibition called This House is a Stage, telling the story of the house and its inhabitants. Before you leave, visit the Potting Shed Cafe. They make everything in their tiny kitchen, and it tastes incredible.
Similarly, Llanrumney Hall, built in 1450, has been restored and is now a community space. There’s a recording studio, pottery, gardening, hot desk facilities, rooms for hire and a café.
On the outskirts of Cardiff is Tredegar House, the home of the Morgan’s for over 500 years, or Dyffryn Gardens, once home to coal magnates John Cory. Both of these are National Trust properties.

Play darts
Darts is a challenging game and takes a lot of practice. However, you don’t need to be skilled to play in Flight Club Cardiff. Everyone has a chance of winning. There are 15 social dart playing areas, four bars, and a massive roof terrace – which is undercover and heated – where you can enjoy some drinks.
