*** 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

The Albufeira da Barragem de Beliche, in Faro District, is a freshwater reservoir whose surface temperatures vary with the seasons and local weather. Typical surface readings tend to range from about 10–14 °C (50–57 °F) in winter, rising to roughly 12–18 °C (54–64 °F) in spring, 18–26 °C (64–79 °F) in summer, and cooling to around 14–20 °C (57–68 °F) in autumn. These are approximate values: shallow bays warm more quickly in sunny months while deeper areas remain markedly cooler, and temperature stratification can create sharp differences with depth. Short-term variation also occurs after heavy rain or strong winds.

Regarding swimming, official rules at Portuguese reservoirs vary and local restrictions can apply at Beliche. Many reservoirs are managed for water supply and flood control, so bathing is frequently discouraged or regulated because of water quality concerns, sudden depth changes, submerged hazards and the absence of lifeguards. Informal swimming does occur in warmer months where access is possible, but visitors should obey on-site signage, municipal regulations and safety advice. For a safe visit, check current local guidance before entering the water.
