*** 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

Pantà de Rialb is a reservoir in Catalonia whose water temperature varies noticeably through the year because of its inland, semi-mountain setting and variable inflows. In winter the surface typically sits around 4–8 °C (39–46 °F), spring brings a rise to roughly 8–15 °C (46–59 °F) as snowmelt and rains feed the basin, and summer surface readings commonly reach 18–25 °C (64–77 °F), occasionally touching the upper 20s °C (around 78–82 °F) during heat spells. In autumn temperatures fall back toward 12–18 °C (54–64 °F). Deeper layers remain colder year-round and shaded coves can be several degrees cooler than open water.

Swimming is possible in many areas of the reservoir but it is not uniformly unrestricted; local rules, seasonal safety warnings and signage can limit access in certain zones (near the dam, intake structures or busy boating areas). Restrictions are motivated by concerns about water quality, sudden level changes, submerged obstacles and boat traffic, as well as public-supply considerations in some sections. Bathers should heed municipal guidance, avoid risky spots, be prepared for cold-water shock at lower temperatures, and favor designated or commonly used beaches and calm coves when conditions and local regulations permit swimming.
