*** 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 San Clemente, situated in Andalusia, typically shows water temperatures that reflect the region’s Mediterranean climate. In winter the surface water commonly cools to roughly 8–12 °C (46–54 °F), while spring brings a gradual rise into the mid-teens, about 12–18 °C (54–64 °F). Summer months are when the reservoir is warmest, with surface temperatures often between 20–26 °C (68–79 °F) and occasionally reaching the upper twenties on heatwave days. During autumn the water generally cools back to roughly 14–20 °C (57–68 °F). These ranges can vary with depth, inflow, recent weather, and year-to-year climatic differences; deeper water typically remains cooler than the surface.

Swimming opportunities at Embalse de San Clemente are influenced by safety, water quality and local regulations rather than temperature alone. Many reservoirs in Andalusia are managed primarily for water supply, irrigation and flood control, so bathing may be restricted or discouraged to protect drinking-water sources and for public safety around changing water levels, submerged hazards and limited lifeguard presence. In some spots informal swimming occurs when local rules permit or enforcement is lax, but visitors should follow posted signs, municipal ordinances and any guidance from reservoir authorities. Checking current conditions and regulations before entering the water is advisable.
