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
The small mountain lake Lagoa do Covão do Quelhas, located in the Guarda District within the higher reaches of Serra da Estrela, is characteristically cold year-round because it is fed by snowmelt and mountain streams. Typical seasonal surface-water temperatures range from near freezing in winter—around 0–4 °C (32–39 °F)—to modestly cool in spring, approximately 4–10 °C (39–50 °F). In the warmest months of summer the surface can warm to roughly 8–15 °C (46–59 °F), while autumn brings a return to springlike values of about 4–10 °C (39–50 °F). These are general ranges; actual temperatures vary with altitude, sun exposure, recent weather and depth of the lake.
Swimming at Lagoa do Covão do Quelhas is possible but uncommon and should be approached with caution. There is typically no formal bathing infrastructure, lifeguards or controlled facilities, and the cold water poses a real risk of cold shock and hypothermia even in summer. Additionally, as part of a sensitive mountain environment, visitors are often encouraged to minimize impact; brief dips occur among hikers, but prolonged immersion or group activities are not recommended for safety and conservation reasons. Anyone considering swimming should be experienced in cold-water conditions, monitor local rules, and prioritize personal safety.
