*** 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
Lake Sirio, a small glacial lake in Piedmont, Italy, experiences clear seasonal variation in water temperature. In winter the surface typically drops to about 2–6 °C (36–43 °F), rising through spring to roughly 8–16 °C (46–61 °F) as air temperatures warm. During the bathing season in July and August the lake commonly reaches 20–26 °C (68–79 °F), and lingering warmth into early autumn can keep temperatures around 10–18 °C (50–64 °F). These figures are typical averages: exact conditions depend on weather patterns, wind, and inflows from springs and streams, so temperatures can vary from year to year and even day to day.
Swimming at Lago Sirio is permitted and popular in the warmer months, with public beaches and designated bathing areas where locals and visitors go for recreation. Authorities monitor water quality, which is generally suitable for bathing, and seasonal lifeguard service or signage may be present at managed spots; however swimming restrictions can be imposed temporarily for safety or quality reasons, so it is advisable to heed local notices. Boat traffic and variable depths mean swimmers should stay within marked areas and exercise common-sense precautions for personal safety.
