The climate of Cardiff (Wales)
Cardiff is the capital of Wales and the largest city in this part of the United Kingdom. Cardiff has a moderate sea climate with mild winters and relatively cold summers. About 1,100 millimeters of precipitation falls on a yearly basis; 95% of which falls in the form of rain. Cardiff gets many rainy days (about 50% of the days get rain). However, thunderstorms are uncommon here. Cardiff only gets 11 days with thunderstorms per year. This is just above the Welsh average of 8 days. During the summer temperatures are between 20-25 degrees Celsius. Night time temperatures are just above 10 degrees Celsius. When there is a warmer period with hardly any wind coming from the sea nights may get muggy. However, because of the influence of the sea and a western current the number of muggy nights is very small.
