*** 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
Length 99.7 km (62.0 mi)
The Río Najerilla, a tributary of the Ebro that runs through parts of northern Spain including sections of Castile and León, shows marked seasonal changes in water temperature. In winter the river is cold, commonly around 4–8 °C (39–46 °F), while spring brings a steady rise to roughly 8–14 °C (46–57 °F) as snowmelt and rains increase flow. Summer surface temperatures in sheltered pools and slower reaches typically range from about 16–22 °C (61–72 °F), though shallow, sun-warmed shallows can be a degree or two higher and deeper or faster-flowing stretches remain noticeably cooler. In autumn temperatures fall back to roughly 10–16 °C (50–61 °F) as air temperatures drop and flows stabilize.
Swimming in the Río Najerilla is possible in many calmer, accessible spots, but it is not universally recommended everywhere along the river. Local regulations, water-quality measures, variable currents, submerged rocks and sudden depth changes make some sections unsafe, especially after heavy rain or during spring high flows. Cold water shock can be a hazard even in summer in deeper pools. Where villages or informal recreational areas have historically been used for bathing, people often swim, but visitors should observe signage, check recent conditions and water-quality reports, and prefer well-known, sheltered spots rather than fast or unfamiliar stretches.
