Location & Local Information

The reservoir commonly known as Albufeira da Barragem da Daroeira experiences distinct seasonal surface temperatures typical of inland water bodies in the Setúbal District. In winter, surface temperatures often range from about 8–14 °C (46–57 °F), rising in spring to roughly 12–18 °C (54–64 °F). Summer brings the warmest conditions, with surface waters frequently between 20–26 °C (68–79 °F), while autumn cools again to around 14–20 °C (57–68 °F). These figures can vary with weather patterns, depth, and local inflows: shallow bays warm faster in calm sun, whereas deeper or shaded areas stay cooler. Short-term swings after heavy rain or cold spells are common.

Swimming at Albufeira da Barragem da Daroeira is a recreational activity many people undertake, but it is subject to local rules and safety considerations. There are often no lifeguards or formal bathing facilities, and authorities may restrict access at times to protect drinking-water quality, to respond to algal blooms, or during reservoir management operations. Submerged hazards, changing currents near outlets, and variable visibility mean swimmers should exercise caution, check any posted notices, and avoid lone or risky dives. When conditions are good and rules permit, the summer temperatures make the reservoir comfortable for bathing, while cooler months are bracing and less suited to prolonged swims.
