Wednesday, July 15th marks Saint Swithin’s Day, with an old belief that if it rains today, this will carry unchanged for the next forty days and forty nights.
According to folklore, if it is fair today, forty days and nights of such weather conditions will follow.
The superstition dates back since records began and revolves around the life and teachings of Swithun, an Anglo-Saxon bishop of Winchester, who passed away in 862 AD.
The following weather rhyme is associated with the annual feast:
“St Swithin’s Day, if it does rain
Full forty days, it will remain
St Swithin’s Day, if it be fair
For forty days, t'will rain no more."
