*** 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 behind the Barragem de Vale do Cobrão in Santarém District shows the seasonal temperature patterns typical of inland Portuguese reservoirs. Surface water in winter usually sits around 8–12 °C (46–54 °F), rising through spring to roughly 12–18 °C (54–64 °F). In summer the lake can warm to about 20–26 °C (68–79 °F) at the surface on sunny days, while autumn sees a gradual cooling to approximately 14–20 °C (57–68 °F). Actual temperatures vary with depth, weather, inflow and recent rainfall, so these figures are indicative of surface conditions experienced by swimmers and boaters rather than precise measurements at all locations or times.

Swimming at Vale do Cobrão is a matter of local rules and conditions rather than a universally designated beach. People do bathe there in warmer months, but official permission, signage and water quality monitoring can change; authorities may restrict access for safety reasons, to protect drinking-water abstraction, during periods of strong currents, low visibility, or algal blooms. There is typically no lifeguard service, so anyone considering a swim should check current municipal guidance, observe on-site notices and be cautious about depth, submerged hazards and variable temperatures before entering the water.
