*** Forecast - Our water temperature forecast
Actual nearshore water temperatures may fluctuate by several degrees from the reported values, especially following heavy rainfall or extended periods of strong winds. Certain wind patterns can cause colder, deeper waters to rise and replace the sun-warmed surface water, leading to noticeable variations.
Our forecast is based on a proprietary mathematical model that considers real-time water temperature changes, historical trends, key weather patterns, wind strength and direction, and air temperature specific to each region. Additionally, we incorporate data from other resorts to enhance accuracy.

Location & Local Information
Lago das Pontes, the flooded former open‑pit mine near As Pontes in Galicia, has water temperatures that reflect its Atlantic, temperate setting and the lake’s depth. Seasonally, surface temperatures typically range from about 6–11 °C (43–52 °F) in winter, 10–16 °C (50–61 °F) in spring, 18–23 °C (64–73 °F) in summer, and 12–17 °C (54–63 °F) in autumn. Strong wind mixing and the lake’s steep contours mean the surface can warm in sunny spells while deeper layers remain noticeably colder; the overall feeling is cooler than many Mediterranean lakes even at the height of summer.
Swimming is permitted in certain, designated parts of Lago das Pontes because the reservoir has undergone remediation and regular water‑quality monitoring, but it is not universally open along all shores. Restrictions exist where steep banks, submerged infrastructure, sudden depth changes or potential contamination risks make entry unsafe. Local authorities mark supervised bathing zones and issue guidance based on bacterial tests and safety conditions; outside those zones swimming is discouraged or prohibited for safety reasons. Visitors should check current municipal information and on‑site signage before entering the water and remain cautious about cold pockets and hidden hazards.
