*** 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 Guadalmellato, located in Andalusia near Córdoba, experiences seasonal variations in surface water temperature typical of Mediterranean reservoirs. In winter the water commonly cools to around 6–12 °C (43–54 °F), while spring temperatures rise into the 12–18 °C (54–64 °F) range as air temperatures warm. Summer brings the warmest conditions, with surface readings often between 20–26 °C (68–79 °F) on calm sunny days, and early autumn typically shows a gradual decline from about 18–22 °C (64–72 °F). Actual temperatures depend on depth, recent weather, and inflows, so localized readings can differ from these general ranges.

Swimming at the Embalse del Guadalmellato is subject to local rules and practical considerations. There are no extensive official beaches like on coastal areas, and because the reservoir functions as a water supply and has varying water levels, submerged hazards, boat traffic and occasional water quality advisories, authorities may restrict or discourage bathing in specific zones. Recreational use such as kayaking, fishing and informal swimming occurs, but visitors should check signage and local regulations and exercise caution for safety and to protect water resources.
