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 Embalse de Barasona-Joaquín Costa in Aragon is a mid-altitude reservoir whose water temperatures show clear seasonal variation. In winter the surface temperature typically falls to about 3–8 °C (37–46 °F), while spring brings a gradual rise to roughly 8–15 °C (46–59 °F). Peak summer warmth usually yields surface readings in the neighborhood of 18–25 °C (64–77 °F), though shallow coves can warm slightly more on hot days. In autumn the water cools again to around 10–16 °C (50–61 °F). These are general ranges: actual temperatures fluctuate with weather, water depth and inflows, so deeper areas remain colder year-round.
Swimming at Barasona is commonly practiced, particularly in summer, because the reservoir is used for recreation and water sports and has accessible shorelines and facilities in some sectors. However, swimming rules vary by zone and season: some areas are designated for bathing while others are reserved for boating, fishing or water management operations, so restrictions may apply for safety or quality reasons. Visitors should heed local signage, be aware of sudden temperature changes, submerged hazards and boat traffic, and confirm whether lifeguards or official bathing zones are in place before entering the water.
