*** 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
Vila Franca de Xira (Portuguese: Vila Franca de Xira) sits on the northern bank of the Tagus estuary within the Lisbon metropolitan area, and swimming conditions reflect a mix of estuarine and inland‑lake influences. Typical water temperatures vary by season: winter averages around 10–15 °C (50–59 °F), spring 13–19 °C (55–66 °F), summer 20–26 °C (68–79 °F) and autumn 15–21 °C (59–70 °F). Sheltered stretches, small reservoirs and river beaches can warm more in hot summers, while colder winters make the water brisk. Local measurements will vary with weather, tides and depth, so these ranges are indicative rather than exact.
Swimming is commonly practiced at designated river beaches and informal spots near Vila Franca de Xira, but whether it is allowed depends on municipal signage and the results of water‑quality monitoring. Authorities may restrict bathing because of strong currents, boat traffic on the Tagus, episodic pollution or algal issues in standing water. Visitors should check recent municipal advisories, look for lifeguards or safety markings, and exercise caution where areas are unsupervised.
