Water Temperature: Daily Trends, Historical Records, and Forecast

✅ As of today, the minimum water temperature is above 82°F (28°C). This is very warm water, which may feel almost hot to most people. Swimming in such conditions is perfect for those seeking relaxation and comfort in the water. These waters are often preferred for relaxation in hot weather, as the water temperature does not cool the body significantly. However, it is important to remember that in such warm waters, caution is necessary, as prolonged exposure without rest can lead to overheating. It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.

*** 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 Bornos, a reservoir in Andalusia, shows noticeable seasonal variation in water temperature that depends on depth, inflow and recent weather. In winter surface temperatures typically sit around 8–14 °C (46–57 °F), rising through spring to roughly 12–20 °C (54–68 °F). In summer the shallows can warm to about 20–26 °C (68–79 °F), while autumn usually brings cooling back to roughly 15–22 °C (59–72 °F). These figures are general and can change with hot spells, cold snaps or heavy rainfall; deeper or shaded areas remain cooler than exposed shallows, and sudden releases or inflows can drop temperatures quickly.

Swimming in the Embalse de Bornos is practiced by locals and visitors, but it is not uniformly regulated as a designated municipal beach. Bathing is often allowed in practice, yet authorities may restrict access near infrastructure, during low-water or maintenance periods, or if water quality concerns (such as algal blooms) arise. Recreational use also coexists with boating and fishing, so safety considerations—currents, submerged obstacles and boat traffic—are important. Anyone planning to swim should check local signage and municipal guidance for current restrictions and water quality advisories before entering.
