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 do Lago Azul in the Santarém District is a freshwater bathing spot known for its clear waters and natural setting. Water temperatures at the lake vary by season: in winter (December–February) surface temperatures commonly range from about 8–12 °C (46–54 °F), spring (March–May) typically warms to roughly 12–18 °C (54–64 °F), summer (June–August) sees the warmest values around 20–26 °C (68–79 °F), and autumn (September–November) cools back to approximately 14–20 °C (57–68 °F). These figures are approximate and can fluctuate with weather patterns, inflows, and depth; shallow, sun‑exposed areas warm more quickly than deeper sections.
Swimming is generally permitted at Praia Fluvial do Lago Azul during the bathing season, especially in summer when local authorities often monitor water quality and may provide lifeguard coverage. Outside peak months, swimming is still possible but visitors should exercise caution because lower temperatures increase the risk of cold shock and hypothermia, and water quality or access may not be routinely checked. Always observe on‑site signage and follow guidance from municipal authorities or lifeguards regarding safe swimming zones and current conditions.
