Location & Local Information

The Embalse de Mansilla, in La Rioja, is a mid-altitude reservoir whose water temperature varies notably with the seasons and with depth. Typical spring surface temperatures range from about 8–14 °C (46–57 °F) as snowmelt and cooler rains feed the basin. In summer, surface temperatures commonly reach 18–24 °C (64–75 °F), occasionally climbing toward 25–26 °C (77–79 °F) in shallow, sheltered bays on hot spells. Autumn sees a decline to roughly 10–16 °C (50–61 °F), while winter surface temperatures often fall into the 4–8 °C range (39–46 °F). Deeper water remains colder year-round, and sudden wind-driven mixing can lower surface temperatures quickly, so perceived warmth depends on location and recent weather.

Swimming at Embalse de Mansilla is possible as a recreational activity, but it is subject to local rules and safety considerations. Because the reservoir serves multiple purposes—water storage, irrigation and environmental management—access can be limited in certain zones or seasons; signage or municipal regulations may prohibit bathing in specific areas to protect water quality or for operational safety. Even where allowed, swimmers should be cautious about cold-water shock, underwater currents, and lack of lifeguards, and check local guidance before entering the water.
