Wales' climate is much milder than expected (considering its location), as all of the British Isles are warmed some by the Gulf Stream and North Atlantic Drift.
There certainly are exceptions, but in general terms winters in Wales are damp, mild and quite windy, and summers pleasant with frequent partly-cloudy days.
Wales can be rainy, especially in fall and the early winter months, and much like Scotland, conditions can change quickly along the western coastline and in the high mountains of the northwest.
Temperatures central and south seldom reach the freezing level (even in winter), and summer highs are usually in the mid-70's. Winter frosts and cooler summer highs are common in the upper elevations of the Cambrian Mountains.
