*** 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

Albufeira da Barragem do Funcho is a freshwater reservoir in the Faro District whose surface temperatures vary seasonally and by depth and location. Typical winter surface temperatures range roughly 8–12 °C (46–54 °F), spring 12–18 °C (54–64 °F), summer 18–26 °C (64–79 °F) and autumn 14–20 °C (57–68 °F). Shallow bays and sheltered arms can warm more quickly in hot weather, while deeper parts remain noticeably cooler even in midsummer. Thermal stratification can occur in warm months, producing colder bottom layers that are a hypothermia risk for swimmers who suddenly dive into deep water.

Swimming at Albufeira da Barragem do Funcho is frequently subject to restrictions and is not generally promoted as an organized bathing site. Reservoirs like Funcho often function as water supply or flood-control infrastructure and can present hazards such as steep banks, submerged obstacles, sudden depth changes and variable water quality after heavy rains, so authorities may prohibit or discourage swimming to protect both public safety and water resources. Informal bathing may still occur, but visitors should check local signage and municipal rules and be cautious about currents, water temperature and the absence of lifeguards before entering the water.
