Swimming in such conditions is perfect for those seeking relaxation and comfort in the water. These waters are often preferred for relaxation in hot weather, as the water temperature does not cool the body significantly. However, it is important to remember that in such warm waters, caution is necessary, as prolonged exposure without rest can lead to overheating.

*** 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 del Zújar, the largest reservoir in Extremadura, experiences marked seasonal variation in surface water temperature that affects swimming comfort and safety. In winter the surface commonly ranges from about 6–12 °C (43–54 °F), spring sees a rise to roughly 12–20 °C (54–68 °F), early autumn temperatures often sit between 15–22 °C (59–72 °F), and in peak summer the water can warm to approximately 25–30 °C (77–86 °F) in shallower bays and more exposed areas. These values vary with weather, depth and inflows: deeper or shaded parts stay cooler while shallow, sunlit areas warm more quickly and may exceed the ranges during heat waves.
Swimming in the Embalse del Zújar is possible and is practiced recreationally, but it is subject to local rules, signage and seasonal safety considerations. Some zones are used for boating, irrigation outlets and water supply management, which can make other parts unsafe; occasional algal growth or poor water quality can also lead authorities to restrict access. Visitors should swim only where permitted, heed municipal notices and be mindful of cold-water shock in winter and hidden currents or steep banks year-round. When conditions are suitable, summer temperatures make swimming comfortable, while colder months require caution or are best avoided.
