*** 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 Embalse de Santolea typically shows marked seasonal variation in water temperature, influenced by its elevation, depth and inflows. In winter the surface can be quite cold, often around 4–8 °C (39–46 °F), while spring brings gradual warming to roughly 8–15 °C (46–59 °F). During the warmest months of summer surface temperatures commonly reach about 18–25 °C (64–77 °F), occasionally rising a few degrees higher in heatwaves, though deeper water remains much cooler. In autumn temperatures usually fall back to the 10–16 °C (50–61 °F) range as air temperatures drop. These figures are approximate and can change with local weather, reservoir level and recent rainfall.

Swimming at the embalse is a seasonal recreational activity and is often practiced in summer when surface temperatures are most comfortable. Whether swimming is officially allowed depends on local management and water-use regulations; some reservoirs permit bathing in designated areas while others restrict it for safety, water-quality or resource-protection reasons. Even where permitted, swimmers should be aware of potential hazards such as sudden depth changes, cold subsurface layers, boat traffic and limited lifeguard presence, and they should follow posted notices and local advice about water quality and access.
