*** 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
Granollers sits inland in Catalonia, so lakes and reservoirs in the surrounding hills tend to show marked seasonal variation in surface temperature. In winter surface waters commonly range from about 6–12 °C (43–54 °F), remaining brisk for most swimmers. Spring brings gradual warming to roughly 12–18 °C (54–64 °F) as daylight and air temperatures rise. In summer sheltered or shallow areas of reservoirs can reach 20–26 °C (68–79 °F) and occasionally 27 °C (81 °F) in heatwaves, making swimming far more comfortable. Autumn cools waters back toward 14–20 °C (57–68 °F) as nights lengthen and temperatures fall.
Swimming opportunities around Granollers depend on the specific waterbody and local rules rather than on temperature alone. Many urban river stretches and some reservoirs restrict or discourage bathing for safety, water-quality or water-supply reasons; submerged obstacles, variable currents and algal blooms also influence suitability. In practice people swim in permitted lake areas or informal spots when conditions and signage allow, but it is important to check municipal regulations and on-site notices. Lifeguard provision is not guaranteed outside official bathing zones, so safety precautions and awareness of local restrictions determine whether swimming is allowed and advisable.
