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 Alqueva sits on the Alqueva reservoir in the Beja District, and water temperatures vary noticeably through the year. In summer the surface usually warms to around 22–28 °C (72–82 °F), with shallower bays sometimes reaching the upper part of that range on hot days. Autumn temperatures commonly fall to roughly 16–22 °C (61–72 °F) as cooling begins, while spring sees a gradual rise from about 14–20 °C (57–68 °F) depending on sunshine and recent weather. In winter the reservoir can be significantly colder, often between 8–14 °C (46–57 °F) at the surface; deeper sections remain cooler year-round. These figures are approximate and local conditions such as wind, depth and inflows produce short-term variations.
Swimming at Praia Fluvial de Alqueva is generally permitted in designated areas because the reservoir is managed for recreation and water quality is monitored, especially during the main season. Supervision and signage are commonly provided in summer but vary by year and specific beach site, so visitors should heed posted information. Calm water and sandy or grassy shores make it suitable for bathing, although colder temperatures outside summer increase risk of cold-water shock and hypothermia. Boating, sudden depth changes and local currents mean swimmers should stay within marked zones and follow safety guidance.
