Cardiff Airport Weather Information

Cardiff weatherOf the four countries which make up the UK, Wales has the highest average rainfall. It is the wettest inhabited place in the UK, has eight of the wettest towns as well as the wettest city. The average yearly rainfall in the City of Swansea ranges from 43” at The Mumbles, and 48” in the city centre, to 56” in its northernmost suburbs such as Ynysforgan. The City of Cardiff is roughly 15% drier.

Wales is hilly and exposed to the south-westerly winds which bring most of the UK's rain, but in the lee of the hills in the "rain shadow" region there are some areas with low rainfall. Less that 30" falls on average along the north Wales coast from Llandudno to the Dee estuary, throughout the Vale of Clwyd, and around Wrexham, Buckley and Shotton.

Like the rest of the UK the weather in Wales is very is unpredictable with warm coastal areas in summer, with May to August the best time to visit as it is sunny and dry.
