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 Llerena, located in Extremadura, typically shows pronounced seasonal variation in water temperature due to the region’s continental-Mediterranean climate and the reservoir’s shallow bathymetry. In winter, surface temperatures commonly range from about 4–10 °C (39–50 °F), rising in spring to roughly 12–20 °C (54–68 °F) as air temperatures warm. Summer surface temperatures often peak between 20–28 °C (68–82 °F), occasionally reaching the upper end during heat waves, while autumn sees a gradual decline back toward spring values. Deeper parts of the reservoir remain cooler year-round, so reported temperatures depend on depth and time of day.
Regarding swimming, regulations and practical considerations at Embalse de Llerena vary: bathing is often not officially promoted because many reservoirs serve irrigation, ecological and water-supply functions, and managers restrict access to protect water quality and ensure safety (no lifeguards, sudden depth changes, underwater obstacles). Informal swimming does occur in accessible coves during warm months, but visitors should heed local signage and municipal rules. For safe recreation, verify current restrictions with local authorities, be aware of fluctuating water quality after heavy rains, and respect protected zones and infrastructure around the dam.
