Current Water Temperature
Water Temperature in the Segre River today is 20.5°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.

The Segre, a river rising in the Catalan Pyrenees and flowing through varied landscapes, shows marked seasonal changes in water temperature. In high mountain reaches and during snowmelt, winter and early spring temperatures commonly sit between about 2–8 °C (36–46 °F). As the river descends into mid and lower reaches, winter values are a bit milder, roughly 4–12 °C (39–54 °F). During late spring and early summer temperatures typically climb into the 10–18 °C range (50–64 °F), and in warm, slow-flowing stretches in midsummer they commonly reach 18–24 °C (64–75 °F), occasionally touching 25–26 °C (77–79 °F) in sheltered reservoirs or pools. Autumn brings a progressive cooling, with temperatures often falling back to about 12–16 °C (54–61 °F) before winter lows return.
Swimming in the Segre is permitted in many places, especially at officially designated bathing sites and river beaches where local authorities monitor water quality and safety. However, not all stretches are suitable: strong currents, sudden depth changes, hydroelectric releases, dams and weirs, and variable water quality can make swimming unsafe or legally restricted in sections of the river. Visitors should use marked swimming areas, heed signage and local guidance, and be aware that colder sections—even in summer—can pose hypothermia risk and impair swimming ability.
