Water Temperature: Daily Trends, Historical Records, and Forecast
⚠️ As of today, the minimum water temperature ranges from 65°F (18°C) to 68°F (20°C). This is already quite warm water, which is ideal for most people. Swimming becomes comfortable, and prolonged stays in the water do not cause discomfort. This temperature is perfect for family trips and for those who prefer warmer water. It is also comfortable for water sports such as surfing or swimming. 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 Río Alagón, known in Spanish as Río Alagón, is a mountain-fed tributary whose water temperature varies considerably with season and location. In winter the river is typically cold, often around 4–8 °C (39–46 °F) in higher and shaded stretches; spring temperatures commonly rise to 8–15 °C (46–59 °F) as snowmelt and runoff increase. By summer, slower, sun-exposed pools can warm to roughly 16–22 °C (61–72 °F), though faster flows and shaded canyons generally remain cooler. In autumn temperatures usually fall back to about 10–16 °C (50–61 °F) as air temperatures and daylight decline. Local variations are common: reservoirs, springs, and upstream tributaries all influence the exact values, and sudden rain or dam releases can rapidly change temperature and flow.
Swimming in the Río Alagón is possible in many calmer sections and natural pools during the warmer months, but it is not universally permitted or safe everywhere. Authorities or land managers may restrict bathing near reservoirs, dams, water intakes, or in protected habitats, and strong currents, submerged rocks, low temperatures, and variable quality after storms pose risks. Visitors should choose established bathing spots, heed signage and local guidance, and remember that even in summer the river can feel noticeably cold compared with coastal waters.
