*** 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
Vernagt-Stausee (Lago di Vernago) in Trentino‑Alto Adige/Südtirol is a high‑alpine reservoir whose water temperatures reflect its elevation and glacier‑fed sources. Spring months are cold, often around 2–8 °C (36–46 °F), warming modestly in early summer to about 6–12 °C (43–54 °F). Peak summer surface temperatures in July and August can reach roughly 10–16 °C (50–61 °F), and on particularly warm, calm days may briefly approach 18 °C (64 °F). By autumn the lake cools again to single digits (about 6–10 °C / 43–50 °F), and in winter surface temperatures typically sit near freezing (0–2 °C / 32–36 °F), with ice or near‑ice conditions possible depending on the season.
Swimming at Vernagt‑Stausee is physically possible but generally uncommon and often discouraged for safety reasons. The water is cold year‑round, creating a real risk of cold shock and hypothermia even in summer; moreover, as a reservoir it can experience sudden level changes and currents related to dam operations, and there are steep, rocky banks and considerable depth. Local regulations and signage may prohibit or limit bathing in certain areas, and there are no lifeguards. Anyone considering entering the water should check current local rules, be prepared for very low temperatures, and weigh the safety risks carefully.
