Location & Local Information

The Embalse de Guadalcacín, near Jerez in Andalusia, shows marked seasonal variation in surface water temperature. In winter the reservoir’s surface commonly ranges from about 8–12 °C (46–54 °F), while spring temperatures rise to roughly 12–18 °C (54–64 °F) as air temperatures warm. During summer, surface waters can reach around 22–28 °C (72–82 °F) on warm spells, although deeper layers remain noticeably cooler; autumn typically brings a gradual cooling to roughly 15–22 °C (59–72 °F). These figures vary with specific weather patterns, wind, inflow from rivers, and depth, so local conditions can produce colder thermoclines and pockets of very cool water even in warm months.

Swimming at the Embalse de Guadalcacín is generally discouraged and in many cases officially restricted because the reservoir is an important water supply and irrigation source, and authorities limit direct bathing to protect water quality and infrastructure. Safety concerns—steep banks, sudden depth changes, submerged hazards, boat traffic and lack of lifeguards—also lead to prohibitions or strong advisories against unsupervised swimming. Informal bathing sometimes occurs along accessible shores in summer, but visitors should follow local signage and regulations and prefer designated recreational sites if available to ensure both safety and the protection of the reservoir’s water resources.
