Annual Water Temperature Trend

Birling Gap sits beneath the chalk cliffs of the East Sussex coast, where the English Channel meets a steep, shingle shoreline. Water temperatures here follow the pattern typical of the southern English coast: winter sea surface temperatures generally range from 7–9°C, spring sees a gradual rise to roughly 8–12°C, summer peak temperatures commonly reach about 15–18°C, and autumn waters usually fall back to around 12–15°C. Conditions can vary day to day with tides, onshore winds and seasonal weather, so short-term surface temperatures may be a degree or two warmer or cooler than seasonal averages.
