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 Embassament de Guadalest, the reservoir behind the dam near the village of Guadalest in Valencia (Alicante province), shows typical Mediterranean reservoir temperatures that vary by season and depth. Surface water in winter commonly sits around 8–12 °C (46–54 °F), rising through spring to roughly 12–18 °C (54–64 °F). In the warmest months surface temperatures can reach about 20–26 °C (68–79 °F), while autumn cooling often brings the surface back to 14–20 °C (57–68 °F). These figures are approximate: actual temperatures depend on recent weather, inflows, and the depth at which measurements are taken, with deeper layers remaining considerably colder year-round.
Swimming in the Embassament de Guadalest is generally restricted. As with many reservoirs that serve water supply, authorities limit bathing to protect water quality and reservoir operations and to reduce safety risks from submerged structures, steep banks and boat traffic. Recreational activities such as boating, kayaking or guided excursions are popular when permitted, but anyone wishing to enter the water should check current local regulations and signage, since rules and seasonal allowances can change and enforcement is intended to safeguard both public safety and the reservoir’s role in regional water management.
