*** 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 la Aceña, in the continental climate of Castile and León, shows clear seasonal variation in surface water temperature. In winter the reservoir typically cools to about 4–10 °C (39–50 °F), while spring brings a rise into the 10–18 °C (50–64 °F) range as air temperatures warm. Summer surface temperatures commonly peak between 20–26 °C (68–79 °F) in warm years, with shallow bays sometimes reaching slightly higher values. In autumn the water usually falls back into the 12–18 °C (54–64 °F) band as days shorten. Local factors such as depth, inflow from cooler rivers, recent rainfall and wind-driven mixing mean that temperatures can vary from place to place within the reservoir and may change quickly near the surface.
Swimming at Embalse de la Aceña is not actively promoted and access depends on municipal regulations and on-site signage: some areas may be used for recreation on a seasonal, informal basis, while others are restricted for safety or water-management reasons. Restrictions are often imposed because reservoirs can supply irrigation or drinking water, present underwater hazards (steep banks, sudden depth changes, submerged structures), and experience variable water quality after storms. Anyone planning to swim should check local rules, observe posted warnings, and take normal open-water safety precautions.
