We are lucky in Anglesey we have relatively mild winters in comparison to rest of the UK. The chart below shows the minimum winter temperatures as recorded by the MET weather station at Valley since 1914. The coldest winter we, in Anglesey, have experienced was the winter known as ‘The Great Freeze of 1963’. It was when the Thames froze as can be seen on the Royal Windsor website. I say we, I wasn’t even born then!
