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 reservoir known locally as Barragem da Meimoa (Portuguese: Barragem da Meimoa) experiences marked seasonal variation in surface water temperature typical of inland central Portugal. In winter surface temperatures commonly range from about 6–12 °C (43–54 °F), spring tends to warm to roughly 12–18 °C (54–64 °F), and summer surface temperatures often reach 20–27 °C (68–81 °F) on warm spells. In autumn the surface typically cools back to about 14–20 °C (57–68 °F). These are approximate surface values; deeper water remains colder year-round due to stratification, and local weather, rainfall and reservoir management can shift these ranges from year to year.
Swimming at the Meimoa reservoir is practiced by visitors during the warmer months, but whether it is officially allowed depends on local signage and water-quality or safety restrictions in force at any given time. Reservoirs present particular hazards — sudden depth changes, submerged objects, variable currents from releases, and typically no lifeguards — so authorities may discourage or temporarily prohibit bathing for safety or maintenance reasons. Before entering the water it is sensible to check current local guidance, look for posted rules on-site, and be aware that deeper or shaded areas will feel considerably colder than surface readings.
