Where should you go in Wales in may when it comes to the weather?
Remember:
The climate in Wales in may is tolerable across the board.
May is not the best month to spend holidays in Wales. The weather in Cardiff, Brecon Beacons (National Park), Pembrokeshire, Conwy and Swansea is just ok. The sun is not there all the time and you might make you wet by rain often. However, if you don't plan a beach and sun travel in Wales but rather discovery of heritage, this climate could be appropriate. In addition, there are surely fewer tourists this month.
It's even worse in Snowdonia National Park and Holyhead and surrounding areas where the climate is very bad. We really do not recommend you to visit these areas this month.
