*** 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 Albufeira da Barragem de Monte Novo, in the Évora District of Portugal, experiences notable seasonal variation in surface water temperature. In winter months temperatures typically sit around 8–14 °C (46–57 °F), cooling further during cold snaps. Spring warms steadily, with surface readings often between 12–20 °C (54–68 °F) as air temperatures rise. Summer brings the warmest conditions, when sheltered shallows can reach 20–26 °C (68–79 °F) or occasionally slightly higher during prolonged heatwaves. In autumn the water cools again, commonly varying from 14–22 °C (57–72 °F) as the reservoir responds to lowering air temperatures and increased rains.

Swimming at Monte Novo is commonly practiced by visitors and locals in suitable areas, but it is not uniformly supervised or formally designated across the whole reservoir. Whether bathing is allowed can depend on local municipal rules, operational conditions of the dam, and regular water-quality monitoring; restrictions are sometimes imposed for safety, water-management or ecological reasons. Swimmers should be aware of hazards such as steep drop-offs, submerged vegetation, fluctuating levels and the absence of lifeguards, and consult on-site signage or local authorities before entering the water.
