This page provides information on the current water temperature in the Avia River, trends, monthly ranges and the forecast for the coming days.
Current Water Temperature
Water Temperature in the Avia River today is 21.7°C.
Water Temperature: Daily Trends, Historical Records, and Forecast
✅ As of today, the minimum water temperature ranges from 68°F (20°C) to 74°F (23°C). The water is warm and pleasant for swimming, and in this range, one can stay in the water for extended periods without the risk of hypothermia. This is the ideal temperature for relaxation, swimming, and water sports. Families with children, as well as outdoor enthusiasts, will enjoy swimming and time spent in the water. For most people, this is the optimal temperature for a comfortable beach experience. 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 Avia, a tributary in Galicia, typically shows cool water temperatures driven by Atlantic weather and upland sources. Seasonal surface temperatures commonly range from about 6–10 °C (43–50 °F) in winter, 10–16 °C (50–61 °F) in spring, 16–22 °C (61–72 °F) in summer, and 12–18 °C (54–64 °F) in autumn. Local variation is significant: shallow, sun-exposed pools and slow-moving stretches warm more in summer, while deep channels, shaded gorges and faster flows remain notably colder. Heavy rains, snowmelt or dry spells can shift these averages by several degrees and affect thermal stratification in wider sections or reservoirs.
Swimming in the Río Avia is possible in many places, and locals often bathe in accessible pools and calmer reaches during the warm months. However, whether swimming is allowed depends on local rules and specific hazards: restrictions may apply near dams, bridges or water infrastructure, and water quality can vary with agricultural runoff or urban discharges. Safety considerations—strong currents, cold-water shock, submerged rocks and sudden depth changes—mean checking signage, recent water-quality reports and local advice is recommended before entering. In short, recreational swimming is common where conditions are suitable, but should be approached with local information and caution.
