Water Temperature: Daily Trends, Historical Records, and Forecast
⚠️ As of today, the minimum water temperature ranges from 60°F (15°C) to 65°F (18°C). The water is comfortable for most people, making it an ideal range for water sports enthusiasts. The temperature does not cause significant discomfort, and swimming will be pleasant for the majority. However, it's important to remember that prolonged exposure to the water can still lead to cooling, so it's essential to monitor the time spent in the water, especially for children or elderly people. It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.

*** 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.

The Rio Sorraia, in Santarém District, typically shows marked seasonal shifts in water temperature. In winter the river often sits around 8–12 °C (46–54 °F), while spring temperatures rise to roughly 12–18 °C (54–64 °F) as daylight and flows increase. By summer, shallow stretches and slower reaches can warm to approximately 18–26 °C (64–79 °F), making conditions most comfortable for bathing. Autumn sees a gradual cooling back toward 12–20 °C (54–68 °F) as air temperatures fall and rainfall replenishes cooler water. Local factors such as depth, shade, upstream releases from reservoirs and recent rainfall will influence these values, so temperatures can vary noticeably from one spot to another along the course.
Swimming in the Sorraia is possible in many calm sections, especially during the warmest months, but it is not universally managed as official bathing water. Safety and suitability depend on current, submerged hazards, bank access, and water quality, since agricultural runoff and seasonal low flows can affect clarity and contamination risk. There are also places with stronger currents or weirs where bathing is unsafe or restricted. Visitors should look for municipal guidance or local signage, consider recent weather and flow conditions, and use caution when entering the river.
