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
Jaca, located in the province of Huesca in the Aragonese Pyrenees, lies along the banks of the Aragón River, which flows from the high mountain glaciers near Canfranc. The river carries cold and clear water, reflecting its alpine origin. During winter, the water temperature is typically between 2 and 5 °C, remaining very cold due to snowmelt and low air temperatures. In spring, as the snow begins to thaw, the temperature rises slightly to 7–10 °C but remains brisk. In summer, near Jaca, the river can reach 14–18 °C in calmer stretches exposed to sunlight, while upstream sections stay colder. By autumn, it cools again to around 8–12 °C.
Swimming in the Aragón River near Jaca is possible but not common, mainly because of its low temperature and strong current in many areas. Most people prefer to enjoy the river for its scenery, fishing, or water sports such as kayaking. During the warmest summer days, locals or adventurous visitors sometimes take quick dips in shallow, safe zones to refresh themselves. The river is best appreciated as part of the natural landscape of the Pyrenees, where crystal-clear water and mountain views create an environment ideal for recreation and relaxation, though not for long swims.
