This page provides information on the current water temperature in the Eo River, trends, monthly ranges and the forecast for the coming days.
Current Water Temperature
Water Temperature in the Eo River today is 18.8°C.
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 Eo, a river in Galicia that forms a tidal estuary on the border with Asturias, tends to have relatively cool water year-round because of its Atlantic influence and upstream mountain inputs. Typical seasonal surface temperatures range roughly from about 6–12 °C (43–54 °F) in winter, warming to around 8–15 °C (46–59 °F) in spring. In the warmest months the river and its lower estuary often reach approximately 14–21 °C (57–70 °F), while autumn sees a gradual decline to roughly 10–16 °C (50–61 °F). Local conditions vary with tides, shading, recent rainfall and depth: shallow, sunlit pools warm more in summer, while deeper channels and upstream reaches stay cooler.
Swimming in the Río Eo is permitted in many informal spots and the estuarine areas see recreational use in summer, but it is not uniformly supervised and access depends on local signage, water quality and safety considerations. The river and its estuary are part of a protected landscape, so visitors should respect conservation rules; strong currents, tidal changes and low temperatures can present hazards, especially for prolonged immersion. Where bathing is popular, brief swims in summer are common, and people often use wetsuits or choose calmer stretches to reduce risk. Always check local guidance before entering the water.
