Annual Water Temperature Trend

Berwick-upon-Tweed sits on the east coast between the North Sea and the mouth of the River Tweed, and sea temperatures there reflect the cool, temperate maritime climate. Throughout the year water is generally cool: in winter it typically ranges from about 5°C to 7°C, in spring from roughly 6°C to 11°C, in summer from approximately 13°C to 16°C (occasionally reaching 17°C in the warmest late summer spells), and in autumn it tends to fall back to around 9°C to 13°C. Shallow sandy bays and the sheltered parts of the estuary can warm a little faster on sunny days, while tidal currents and deeper channels remain colder; local variability and changing weather mean conditions can shift noticeably week to week.
