*** 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
Praia Fluvial de Monsaraz sits on the shores of the Alqueva reservoir and experiences typical seasonal variations in water temperature for a large inland body of water in southern Portugal. In summer, surface temperatures commonly range from about 22–26 °C (72–79 °F) and can reach locally higher values on very hot days, occasionally up to around 28 °C (82 °F). Spring temperatures tend to be cooler, roughly 14–20 °C (57–68 °F), while autumn typically sees 15–22 °C (59–72 °F). Winter surface temperatures are cooler still, often near 10–14 °C (50–57 °F). Because the reservoir is deep in places, colder layers can exist below the surface, so overall thermal conditions can vary with weather and wind.
Swimming at Praia Fluvial de Monsaraz is generally permitted in designated bathing areas and is most popular in the warmer months when surface temperatures are comfortable. Local authorities or operators usually monitor water quality at official beaches and may provide lifeguards during the high season; however, swimmers should respect posted signs, avoid areas with boat traffic or sudden depth changes, and be aware that reservoir conditions (cold thermoclines, currents near inlets or the dam) can affect safety.
