*** 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 do Divôr (in Portuguese, Albufeira da Barragem do Divôr) typically shows marked seasonal variation in surface water temperature due to its location in the Évora district of Alentejo. In winter months the water usually cools to around 8–12 °C (46–54 °F), while spring sees a gradual rise into the mid-teens at approximately 12–18 °C (54–64 °F). Summer surface temperatures commonly reach the warmest range, roughly 20–26 °C (68–79 °F), though shallow, sheltered areas can be a few degrees warmer on hot days. Autumn temperatures tend to fall back into the 14–20 °C (57–68 °F) band as the reservoir cools again.

Swimming in the reservoir is practiced by locals and visitors, but whether it is officially allowed can vary and is often subject to municipal rules, seasonal water-management needs and safety considerations. Authorities sometimes discourage or restrict bathing because the reservoir supports irrigation and water supply, has variable water levels and submerged hazards, lacks lifeguard supervision, and can present boat traffic or sudden temperature changes. Water quality can also fluctuate after heavy rains. Anyone planning to swim should check local signage and regulations, be mindful of changing conditions, and prioritize personal safety.
