*** 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
Aranda de Duero, in the heart of Castile and León, lies close to stretches of the Duero river and several small reservoirs where water temperature follows a typical inland continental pattern. In winter the water commonly sits around 4–8 °C (39–46 °F), spring warms it to roughly 8–16 °C (46–61 °F), and in summer surface temperatures often range from 18–26 °C (64–79 °F), occasionally rising toward 28 °C (82 °F) during prolonged heat. Autumn sees a gradual cooling back to about 10–16 °C (50–61 °F). Shallow embayments and calm reservoir areas warm faster than flowing sections of the river, so local readings can vary by several degrees.
Swimming opportunities exist but are conditional: in the warmer months people commonly bathe in designated recreational reservoirs or managed river spots where authorities allow it and where signage, water quality monitoring and safety measures are in place. Many water bodies used for drinking supply, irrigation or with steep banks, strong currents or ecological protections prohibit bathing, and lifeguard coverage is often limited to official summer beaches. Visitors should check municipal rules and current water-quality advisories before entering the water, and be mindful of submerged hazards and temperature-related risks such as cold shock outside peak summer warmth.
