*** 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 Alserio, in Lombardy, is a relatively small, shallow lake whose water temperatures vary notably through the year. In winter the surface commonly ranges from about 1–6 °C (34–43 °F), while spring brings a gradual rise to roughly 7–15 °C (45–59 °F). Peak summer temperatures in sheltered, shallow parts of the lake can reach around 20–26 °C (68–79 °F), and autumn sees cooling back to roughly 10–18 °C (50–64 °F). Because the lake is not very deep, it tends to warm up faster in calm, sunny conditions, but it can also cool quickly and be affected by seasonal weather swings.
Swimming in Lake Alserio does take place and is generally allowed in non-protected, designated spots, though official facilities are limited compared with larger tourist lakes. The lake’s shallow, eutrophic character means that warm periods can encourage algal growth or reduced clarity, and some shoreline zones are protected for nature conservation; for those reasons local authorities sometimes restrict bathing in specific areas or post guidance about water quality. In practice visitors swim in suitable sections during the summer months when surface temperatures are most comfortable, taking account of posted notices and local recommendations about safe and permissible places to enter the water.
