*** 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
The reservoir known locally as Albufeira da Barragem de Fagilde, in the Viseu district of Portugal, has water temperatures that vary seasonally and with depth and weather. Typical surface temperatures in winter commonly range from about 6–12 °C (43–54 °F), rising through spring to roughly 10–18 °C (50–64 °F). In summer, on warm, calm days, surface readings often reach 20–26 °C (68–79 °F), while autumn sees a gradual cooling back toward spring values. Deeper water remains colder year-round, and short-term fluctuations occur after rain or prolonged heat, so local conditions can differ from these averages.
Swimming at the Albufeira da Barragem de Fagilde is subject to local regulation and practical constraints rather than being universally encouraged. Some reservoirs in the region restrict bathing to protect water quality, public safety, and reservoir operations; hazards include variable depths, submerged obstacles, sudden currents, and lack of lifeguards. Where bathing is permitted, it is typically advised only in designated, signposted areas and when water-quality monitoring indicates it is safe. Visitors should check local signage or municipal guidance before entering the water and be prepared for cooler temperatures below the surface even in summer.
