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 Portbou is a small reservoir in the far northeast of Catalonia whose water temperatures vary with season, coastal influence and depth. Typical surface temperatures in winter commonly sit between about 6 and 12 °C (43–54 °F), rising through spring to roughly 10–18 °C (50–64 °F). In summer the shallows can warm to roughly 18–24 °C (64–75 °F), while deeper or shaded areas remain cooler. During autumn temperatures generally fall back toward 12–20 °C (54–68 °F). These ranges are approximate and can shift year to year depending on rainfall, river inflows and local weather; stratification in deeper sections can leave bottom waters noticeably colder than surface readings.
Swimming at Pantà de Portbou is subject to local regulation and is often discouraged or prohibited at many Catalan reservoirs for reasons of water supply protection, safety and environmental management. Authorities commonly restrict bathing to protect drinking-water quality, to avoid risks from steep banks, submerged obstacles and sudden depth changes, and to limit disturbances to habitats. Where swimming is permitted, it is usually confined to clearly marked areas and subject to municipal rules; in other cases only passive recreation such as walking or fishing may be allowed. Visitors should check current local signage or municipal guidance before entering the water and be mindful of cold temperatures and hidden hazards.
