Current Water Temperature
Water Temperature in the Ter River today is 18.1°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.

Location & Local Information
The Riu Ter, rising in the eastern Pyrenees and flowing to the Mediterranean near Girona, shows clear seasonal swings in water temperature driven by snowmelt, flow volume and local weather. In winter the river is typically cold, around 4–8 °C (39–46 °F). Spring sees a progressive warming as flows moderate, roughly 6–14 °C (43–57 °F). Peak warmth occurs in summer when shallow, slow stretches and reservoirs can reach about 18–26 °C (64–79 °F), and during heatwaves some sheltered pools may climb into the upper 20s °C (80–82 °F). Autumn temperatures commonly fall back into the 12–18 °C (54–64 °F) band as rainfall and cooler air reduce river heat.
Swimming is possible in many parts of the Riu Ter, especially at designated bathing spots, reservoirs such as the Sau area and calm downstream pools, but whether it is allowed depends on local regulations and signage. Safety and water quality considerations matter: strong currents, sudden depth changes and variable turbidity after rains can make some reaches unsafe, and water quality can deteriorate near urban or agricultural sections. Always follow posted rules, seasonal advisories and local guidance; where permitted, summer is the most comfortable time for bathing because temperatures are warmest and flows are generally lower.
