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
The Pantà de Graus, a reservoir in Catalonia, experiences marked seasonal variation in surface water temperature. In winter the surface commonly sits around 6–10 °C (43–50 °F), while spring brings a gradual rise to roughly 10–16 °C (50–61 °F). By summer the reservoir often reaches its warmest values, typically between 18–26 °C (64–79 °F) and occasionally touching 27–28 °C (81–82 °F) during heat waves. Autumn temperatures decline again into the 12–18 °C (54–64 °F) range. These figures are approximate averages for surface layers; deeper water remains substantially colder year‑round and a thermocline can develop in summer, so actual temperatures vary with depth, weather and inflow.
Swimming at Pantà de Graus is subject to local regulation and practical considerations. In many reservoirs in the region, bathing is permitted in designated or commonly used spots when authorities do not impose restrictions, but there can be prohibitions linked to water supply protection, ecological management, safety hazards such as sudden depth changes or boat traffic, and water quality advisories after heavy rains. If you plan to swim, check on-site signage or local rules; also be mindful of cold-water shock early and late in the season and of variable undercurrents and submerged obstacles that make reservoir swimming different from coastal bathing.
