*** 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 Sierra Boyera, located in Andalusia, Spain, is a man-made reservoir whose surface temperatures follow the region’s seasonal patterns. In winter the water typically cools to roughly 8–12 °C (46–54 °F), spring brings a gradual rise to around 12–18 °C (54–64 °F), summer surface temperatures often reach 20–26 °C (68–79 °F) on warm days, and autumn sees a decline back toward 14–20 °C (57–68 °F). These ranges can vary with weather, depth, and inflow; deeper or shaded parts remain colder year-round, while shallow bays warm most quickly in summer. Sudden drops in temperature below the surface and strong currents near the dam or inflows can create localized hazards.

Swimming opportunities at Embalse de Sierra Boyera are limited and depend on local regulations and safety considerations. As a working reservoir used for water management and irrigation, authorities may restrict bathing to protect water quality and to prevent accidents, and there are generally few official facilities or lifeguards. In practice some visitors swim in accessible spots when conditions are calm, but this is often discouraged for legal and safety reasons. Anyone planning to swim should observe posted rules and be aware of changing temperatures and potential underwater hazards.
