*** 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 dels Guiamets, a reservoir in the Priorat region of Catalonia, shows a clear seasonal pattern in surface water temperatures. In winter the water commonly sits around 5–8 °C (41–46 °F), rising through spring to roughly 8–15 °C (46–59 °F). Summer months typically bring the warmest conditions, with surface temperatures often between 18–25 °C (64–77 °F) and occasionally reaching 26–28 °C (79–82 °F) on hot, calm days. During autumn the temperature usually falls back to about 12–18 °C (54–64 °F) as air temperatures cool and inflows increase. These ranges can vary year to year depending on rainfall, inflow, and heat waves.

Swimming at Pantà dels Guiamets is commonly practiced and generally allowed in many parts of the reservoir, which people use for bathing and non-motorized water recreation, but conditions and regulations may vary. Restrictions or local prohibitions can apply near infrastructure such as the dam, intake structures, or areas used for water management, and water quality can fluctuate after heavy rains or agricultural runoff, so signage and local advice should be followed. Safety considerations—cold deep water, sudden drop-offs, and limited rescue services—mean swimmers should exercise caution, wear flotation if uncertain, and avoid isolated spots.
