*** 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 known locally as Albufeira da Barragem da Venda Nova sits in the Setúbal District and reflects the region’s Mediterranean climate in its water temperatures. Typical surface temperatures range seasonally from roughly 8–14 °C (46–57 °F) in winter, through about 12–18 °C (54–64 °F) in spring, to warmer summer values around 20–26 °C (68–79 °F). Autumn sees a gradual cooling back to roughly 14–20 °C (57–68 °F). These figures can vary year to year with rainfall, inflow, and air temperature, and deeper parts of the reservoir remain colder than surface readings.

Swimming at Albufeira da Barragem da Venda Nova is a mixed situation: while people do bathe there informally, swimming is not universally promoted and may be restricted or discouraged by local authorities. Reasons include safety hazards such as sudden depth changes, underwater obstacles and boating activity, as well as concerns about water quality and the reservoir’s role in water supply and irrigation. Visitors should look for on-site signage or municipal guidance before entering the water; where swimming is permitted, summer surface temperatures are the most comfortable, whereas spring and autumn waters can feel brisk and winter conditions are typically too cold for casual bathing.
