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.

The Río Nela, a tributary flowing through the northern part of Castile and León, shows typical continental and mountain-influenced temperature patterns. In winter the water is usually cold, often around 4–8 °C (39–46 °F), especially in upstream or shaded stretches. During spring temperatures rise as snowmelt and rain increase flow, typically ranging from about 6–14 °C (43–57 °F). In summer the shallower, slower reaches can warm more noticeably, commonly between 14–22 °C (57–72 °F) on warm days, while deeper or faster sections stay cooler. Autumn sees a steady decline, with waters typically between 8–16 °C (46–61 °F) as flows and air temperatures fall. Local variations are frequent depending on altitude, shading and recent precipitation.
Swimming in the Río Nela is possible in calmer, accessible sections and is practiced informally in warm months, but it is not uniformly regulated as official bathing areas along the whole course. Whether swimming is allowed depends on local municipal rules, water quality results and safety considerations: strong currents, sudden depth changes, cold temperatures even in summer, and upstream infrastructure such as weirs or small dams can make some spots hazardous. Visitors should check local signage and recent water-quality reports, choose sheltered or monitored pools if available, and exercise caution to avoid risks associated with cold water and river dynamics.
