If you're planning anything outdoors in Swansea, the city's full Atlantic exposure on the Welsh south coast makes it one of the wettest places in the UK — significantly wetter than Cardiff just down the road, with no mountain protection from the systems coming in off the sea. Winters are mild thanks to the Bristol Channel, but rainfall totals are real, and December is properly wet. The trade-off is that the same exposure brings dramatic skies and the Gower coast on your doorstep.
