Water Temperature: Daily Trends, Historical Records, and Forecast
❌ As of today, the minimum water temperature ranges less than 41°F (5°C). Such water is extremely cold and not recommended for swimming without proper preparation. In these conditions, the risk of hypothermia is very high, and prolonged exposure to the water can be hazardous to your health. If you decide to swim, it is important to have the appropriate gear, such as a wetsuit. Typically, only experienced swimmers or those who practice winter swimming venture into such waters. 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.

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
Lake Fontana Bianca (Lago di Fontana Bianca) in Trentino-Alto Adige/Südtirol is a small alpine lake whose water temperatures reflect its altitude and mountain-fed sources. In winter the surface is often at or just below freezing, around 0 °C (32 °F) and can be ice-covered. During spring the lake typically warms to roughly 4–8 °C (39–46 °F) as snowmelt feeds it. In summer the warmest period, temperatures commonly reach about 10–15 °C (50–59 °F), with occasional warm spells pushing pockets of water up to 16–18 °C (61–64 °F). By autumn the lake cools again to roughly 6–10 °C (43–50 °F). Local weather, inflow from springs or streams, and seasonal sunlight all cause variability from year to year.
Swimming is generally permitted in such natural mountain lakes, and some visitors do take short dips in the warmest weeks. However, the water remains cold compared with lowland bathing waters, so prolonged swimming carries a real risk of cold shock and hypothermia. There are often no lifeguards or rescue facilities at remote alpine sites, and access or use can be subject to local conservation rules or signage. For safety, swimming is best limited to brief, supervised swims in the peak summer months, using common-sense precautions and checking local guidance.
