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 Rules, a reservoir in Andalusia, experiences typical seasonal water temperatures influenced by Mediterranean climate and local inflows. In winter the surface water commonly ranges from about 10–14 °C (50–57 °F), while spring sees a gradual rise to roughly 12–20 °C (54–68 °F) as daylight and air temperatures increase. During the warmest months of summer the surface can warm to approximately 20–25 °C (68–77 °F) in sheltered, shallow areas at midday, although deeper or shaded sections remain cooler. In autumn temperatures usually fall back to the 15–22 °C (59–72 °F) bracket as cooling weather and increased rainfall mix the reservoir. Actual conditions vary with recent weather, water release patterns and depth, so localized pockets of much colder water are possible even in summer.
Swimming at Embalse de Rules is subject to local regulations and practical restrictions. Many inland reservoirs in the region are managed for water supply and irrigation and therefore have official limits on bathing to protect water quality and for safety reasons; Rules has historically been treated cautiously for these same concerns. Aside from regulatory prohibitions, hazards such as steep banks, submerged structures and sudden depth changes make unsupervised swimming risky. Visitors who consider entering the water should check current municipal signage and advisories, and bear in mind that permitted or informal bathing occurs at one’s own risk.
