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
Embalse de Valmayor, a reservoir to the west of Madrid, shows pronounced seasonal variation in surface water temperature. In winter the surface typically ranges from about 6 to 12 °C (43 to 54 °F), while spring waters warm into roughly 10 to 18 °C (50 to 64 °F) as air temperatures rise. During summer, sheltered shallows and sun-warmed areas can reach approximately 18 to 26 °C (64 to 79 °F) on warm afternoons, although deeper water remains noticeably cooler. In autumn temperatures usually fall back into the 12 to 20 °C (54 to 68 °F) range. These figures are approximate: local weather, wind, depth and inflows cause day-to-day variation and thermoclines can make deeper swimming unexpectedly cold.
Swimming in Embalse de Valmayor is generally not permitted for public health and safety reasons: the reservoir is part of the regional water supply system and authorities restrict bathing to protect water quality and to limit contamination risks. Safety considerations are also cited, including sudden depth changes, submerged obstacles and the absence of lifeguard coverage in many areas. Recreational activities such as sailing, rowing or fishing may be allowed in designated zones under regulation, and informal or occasional bathing sometimes occurs despite rules; visitors should follow local signage and municipal regulations before entering the water.
