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.

*** 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
Lago di Beauregard in the Aosta Valley is a small high‑mountain lake whose surface temperatures reflect its altitude and snowmelt feed. Seasonal surface temperatures commonly range from about 4–10 °C (39–50 °F) in spring and autumn, rise to roughly 12–18 °C (54–64 °F) in the warmest weeks of summer, and drop toward 0 °C (32 °F) in winter when ice or near‑freezing conditions are frequent. Because the lake is fed by meltwater and has limited volume, even midsummer water can feel cold compared with lowland bathing waters; wind and weather swings can also alter surface temperatures quickly.
Swimming in Lago di Beauregard is generally possible but informal: there are typically no lifeguards, marked bathing areas, or staffed facilities, and local rules or temporary restrictions may apply, so visitors should check on site. The main reason swimming is feasible is simply access to the shore and the absence of prohibitive infrastructure, but the cold temperatures, potential for rapid weather changes, and rocky approaches make brief swims, a wetsuit, and caution advisable. For most people, late July and August offer the most comfortable window for a short dip.
