A couple have told about an "extraordinarily powerful" surge in a Welsh sea harbour where the tide went into reverse due to a rare phenomenon.
Charles and Claire Davies, whose home overlooks Solva harbour, in Pembrokeshire, saw what is known as a "meteotsunami" where the sea suddenly rushed in and out at high speed last Saturday.
"The water appeared to be running out of the harbour rather than in," Charles told WalesOnline.
