Annual Water Temperature Trend

Clevedon sits on the edge of the Severn Estuary in North Somerset, where the dramatic tidal range and open estuary conditions strongly influence water temperature and bathing conditions. Seasonal sea temperatures around Clevedon typically range from about 6–9 °C in winter (December–February), rising to roughly 8–12 °C in spring (March–May). In summer (June–August) the water can reach approximately 14–18 °C on the warmest weeks, while autumn (September–November) usually sees temperatures settle between about 10–14 °C. These figures can vary year to year and change locally with tides, river outflow and weather, so the water you encounter at the shore can feel noticeably colder or warmer depending on timing and conditions.
