*** 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 El Portillo in Andalusia experiences typical seasonal variability in surface water temperature. In winter, surface temperatures commonly range from about 8–12 °C (46–54 °F), while spring sees a gradual rise to roughly 12–18 °C (54–64 °F). In summer the reservoir can warm to around 20–26 °C (68–79 °F) on calm, sunny days, though shallow bays may be a few degrees warmer. During autumn temperatures generally fall back to the 14–20 °C (57–68 °F) band. These figures are approximate; actual temperatures depend on recent weather, inflows, wind, and depth, with deeper parts remaining considerably cooler than the surface and daily swings possible on sunny versus cloudy days.

Swimming at Embalse de El Portillo is frequently practiced but is subject to local rules and occasional restrictions. Authorities sometimes permit bathing because many reservoirs are used for recreation, but they may also prohibit swimming at times to protect drinking-water quality, ensure safety near infrastructure, or preserve firefighting reserves. There are typically no lifeguards, and risks include cold water shock, variable depths, underwater obstacles and boat traffic. For these reasons it is advisable to check municipal signage or local advisories before entering the water and to take standard precautions if swimming is allowed.
