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 Albufeira da Barragem de Póvoa e Meadas typically shows marked seasonal variation in surface water temperature. In summer (June–August) surface temperatures commonly range from about 20–26 °C (68–79 °F), and during heat waves can reach 27–30 °C (81–86 °F). Spring (March–May) waters usually sit between roughly 12–20 °C (54–68 °F), while autumn (September–November) cools from about 14–22 °C (57–72 °F). Winter readings (December–February) are the coldest, often 6–12 °C (43–54 °F). These figures refer to surface temperatures; deeper water is colder year-round due to stratification, and local conditions such as recent rain, wind and reservoir releases can change temperatures quickly.
Swimming is commonly practiced at reservoirs in the Portalegre district and there are recreational zones at Póvoa e Meadas where bathing is generally allowed, because the area is used for leisure and local oversight monitors activities. However, permission can be limited or temporarily suspended for reasons of safety (strong currents near outlets, submerged structures, sudden level changes), water quality concerns (algal blooms after warm weather), or water-management and environmental protection rules. Visitors should follow on-site signage and local authority guidance before entering the water to ensure conditions are safe and swimming is permitted.
