*** 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

Lagoa de Óbidos, in the Leiria District of Portugal, is a shallow coastal lagoon whose water temperatures reflect both Atlantic influence and local heating. Typical seasonal surface temperatures range from about 12–15 °C (54–59 °F) in winter to roughly 18–24 °C (64–75 °F) in summer, with spring values near 13–18 °C (55–64 °F) and autumn usually around 15–20 °C (59–68 °F). Because the lagoon is shallower and more sheltered than the open ocean, it tends to warm earlier in late spring and stay milder into autumn; occasional hot spells can push parts of the lagoon toward 25–26 °C (77–79 °F).

Swimming in Lagoa de Óbidos is a common recreational activity and is generally allowed, especially during the warmer months when conditions are calm and temperatures are comfortable. The lagoon’s sheltered waters make it suitable for family swimming, kayaking and windsurfing, but water quality and safety can vary by location and season. Local authorities may close or advise against bathing if pollution, algal blooms or strong tidal flows create hazards, so swimmers should follow on-site signage and recent water-quality information before entering the water.
