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
Praia Fluvial da Amieira (in Portuguese: Praia Fluvial da Amieira) sits on a calm reservoir in the Beja District and experiences the kind of seasonal water temperature variation typical of inland Alentejo lakes. In winter the surface water commonly falls to around 8–12 °C (46–54 °F). Spring brings a gradual rise, roughly 13–18 °C (55–64 °F) as air temperatures warm and solar input increases. Peak summer temperatures are usually between about 22–27 °C (72–81 °F) in sheltered areas and shallow bays, though deeper sections remain somewhat cooler. During autumn the lake cools back to approximately 15–20 °C (59–68 °F) as daylight and air temperatures decline.
Swimming at Praia Fluvial da Amieira is generally permitted during the warmer months, and many visitors bathe there in summer because the reservoir’s calmer waters suit recreational swimming. Local authorities typically monitor water quality and safety, and bathing may be limited or temporarily prohibited after heavy rains or if monitoring indicates contamination or hazardous conditions. Lifeguards are not guaranteed year-round, so swimmers should heed on-site signage, follow any seasonal safety provisions, and take usual precautions—staying in supervised zones when provided and avoiding cold-water immersion outside peak season.
