*** 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 Retortillo, like many inland reservoirs in Andalusia, shows clear seasonal swings in water temperature. In winter the surface typically sits around 8–12 °C (46–54 °F), rising through spring to roughly 12–19 °C (54–66 °F). Peak summer temperatures often reach about 20–26 °C (68–79 °F) on warm, calm days, while autumn sees a gradual cooling to roughly 14–20 °C (57–68 °F). Actual readings depend on recent weather, reservoir depth and inflows: shallow areas warm faster and can exceed these ranges during heat waves, whereas deeper or spring-fed zones remain cooler.

Swimming opportunities at the Embalse de Retortillo vary by management rules and local conditions. In many Andalusian reservoirs swimming is permitted when water quality and safety allow, especially during summer when temperatures are comfortable; however some reservoirs prohibit bathing because they serve as drinking-water sources or for safety reasons. Even when allowed, hazards such as sudden depth changes, submerged obstacles, boat traffic and absence of lifeguards mean swimmers should exercise caution. It’s advisable to check local signage or with the reservoir authority for current restrictions and water-quality advisories before entering the water.
