*** 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
Tortosa, in Catalonia, sits on the lower Ebro and is close to several reservoirs and calm river stretches often used like lakes for recreation. Water temperatures in these freshwater bodies follow a clear seasonal pattern: in winter they commonly range from about 8–14 °C (46–57 °F), spring typically warms to roughly 12–20 °C (54–68 °F), summer brings the warmest conditions around 20–26 °C (68–79 °F), and autumn cools back to approximately 14–20 °C (57–68 °F). Exact figures fluctuate with recent weather, reservoir releases, depth and flow; shallow coves heat up fastest while flowing channels remain cooler.
Swimming is generally permitted in designated bathing areas around Tortosa when local authorities have certified water quality and safety, and many visitors swim during the warmer months because temperatures then are comfortable for bathing. However, access can be restricted at times for reasons such as strong currents, boat traffic, maintenance of dams, algal blooms or declining water quality; signage and municipal guidance indicate allowed sites. Bathers should follow posted rules, check current water-quality reports and be mindful of variable conditions—especially near outflow points or where submerged hazards exist—to ensure safe swimming.
