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 del Rumblar, a reservoir in Andalusia, typically shows marked seasonal variation in water temperature driven by the Mediterranean climate and local elevation. In winter, surface temperatures often sit between about 8 and 14 °C (46–57 °F). Spring warming raises temperatures to roughly 12–20 °C (54–68 °F) as air temperatures climb. Peak summer surface temperatures commonly range from about 20 to 26 °C (68–79 °F), though shallow bays can warm a few degrees higher on hot, calm days. Into autumn the water cools again, with typical values around 14–20 °C (57–68 °F). These figures are approximate and can vary with depth, recent weather, inflow from cooler streams, and seasonal rainfall.

Swimming at the Embalse del Rumblar is subject to local rules and practical limitations; many reservoirs in Andalusia restrict bathing to protect drinking-water quality and for safety reasons, and Rumblar is frequently treated the same way. Restrictions are put in place because reservoirs can have submerged hazards, sudden depth changes, cold thermoclines, and the potential for algal blooms or contamination that make unsupervised swimming risky. Visitors should consult local signage or municipal authorities before entering the water; where allowed, swimmers should take normal precautions regarding temperature, currents, and water quality.
