The Wash [SEP] Water temperature
The Wash varies enormously in water temperature throughout the year. Winter temperatures are brought near freezing from the cold North Sea flows. Summer water temperatures can reach after prolonged high ambient air temperature and sun. This effect, which typically happens in the shallow areas around beaches and often only in pockets of water, is exaggerated by the large sheltered tidal reach.
