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.

Río Cares, flowing through the Picos de Europa in Asturias, is a mountain river with characteristically cold water. Typical seasonal surface temperatures are roughly 2–6 °C (36–43 °F) in winter, 4–10 °C (39–50 °F) in spring, 10–18 °C (50–64 °F) in summer, and 6–12 °C (43–54 °F) in autumn. Local variations are frequent: shallow, sun-warmed pools on hot summer days can briefly reach around 20 °C (68 °F), while snowmelt and heavy rain can drop temperatures and raise flow rates quickly. Temperatures are measured at the surface and can feel several degrees colder in deeper or shaded sections.
Swimming in the Río Cares is possible in calmer, lower stretches and in isolated pools, and there is no blanket prohibition across all reaches, but it is not broadly recommended. Much of the river runs through steep gorges, protected areas and remote terrain where strong currents, cold-water shock, slippery rocks and sudden flow changes pose safety hazards. In addition, sections within or adjacent to the national park may have local rules or conservation considerations, so visitors should check signage, local guidance and exercise caution if they choose to enter the water.
