Annual Water Temperature Trend

Foz lies on the Cantabrian coast of Galicia, where the Atlantic influence gives the sea a cool, variable character through the year. Typical water temperatures in the area range from about 12–14 °C in the coldest months of winter (December–February), gradually rising to roughly 13–16 °C in spring (March–May). Summer months (June–August) bring the warmest conditions, with averages commonly between 17–20 °C, although short-lived peaks or cooler spells can occur depending on weather patterns and coastal upwellings. In autumn (September–November) temperatures generally fall back to around 15–18 °C. Local factors such as exposure, tides and the sheltering effect of coves mean that water at some beaches will feel a degree warmer or cooler than these overall figures.
