*** 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
Tolosa, a town in Gipuzkoa in the Basque Country, sits on the Oria river rather than by a large natural lake, though small reservoirs and leisure ponds are found in the surrounding hills. Water temperatures in those inland bodies typically follow a temperate Atlantic pattern: winter surface temperatures commonly range from about 6–10 °C (43–50 °F), spring from roughly 8–15 °C (46–59 °F), summer from about 18–24 °C (64–75 °F), and autumn from approximately 10–16 °C (50–61 °F). These figures are general estimates for small lakes and reservoirs in the area; exact temperatures vary with depth, sunshine, recent weather and inflow from rivers like the Oria.
Swimming is possible in Tolosa’s vicinity but usually only in designated sites where authorities monitor water quality and safety. The Oria river has a number of informal bathing spots, yet strong currents, variable clarity and occasional agricultural runoff mean some stretches are unsuitable or restricted. Local reservoirs or managed leisure lakes may allow bathing when signage and water-quality tests indicate it is safe. In short, swimming is neither universally prohibited nor universally advisable across every waterbody near Tolosa; permission and safety depend on local regulations, posted notices and current water-quality and flow conditions.
