*** 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 de Arcos (Lake of Arcos Reservoir) in Andalusia experiences typical Mediterranean inland reservoir temperatures that vary significantly by season. In winter the surface water commonly ranges from about 8–12 °C (46–54 °F), moving up in spring to roughly 12–18 °C (54–64 °F) as the weather warms. Summer surface temperatures can reach approximately 20–27 °C (68–81 °F) on warm days, making the reservoir comparatively mild for swimming, while autumn usually cools back to the 14–20 °C (57–68 °F) band. These values are approximate and can change with local weather, depth, and water inputs; deeper or shaded areas remain colder year-round.

Swimming at Embalse de Arcos depends on local rules and practical considerations rather than a simple yes or no. Many reservoirs in the region are managed primarily for water supply, irrigation and flood control, so bathing may be discouraged or restricted because of water quality monitoring, safety hazards like submerged structures and intake currents, and changing water levels. Informal bathing and recreation including boating and fishing occur, but official permission and designated spots vary by municipality and reservoir management; visitors should follow local signage and regulations and be aware of safety risks.
