*** 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 Gusana (Italian: Lago di Gúsana) is a small reservoir in central Sardinia whose water temperatures reflect its inland, hilly setting. In winter months (December–February) surface temperatures typically sit around 6–10 °C (43–50 °F), while spring (March–May) brings a gradual rise to roughly 10–16 °C (50–61 °F). Peak warmth occurs in summer (June–August), when surface water commonly reaches about 20–26 °C (68–79 °F), and early autumn (September–November) usually registers between 14–20 °C (57–68 °F). These values are seasonal averages; actual temperatures vary with weather, depth, and local inflows, so cooler layers can persist even in summer.
Swimming at Lake Gusana is a familiar recreational activity, especially during the warmest months, and many visitors and locals bathe from informal shore spots. There is no consistent island-wide prohibition, but restrictions can apply near hydraulic infrastructure, steep banks or when local authorities issue safety or water-quality advisories. There are typically no lifeguards, and conditions such as sudden wind, submerged hazards, or reservoir management operations can make some areas unsafe. Visitors planning to swim should follow posted rules, avoid restricted zones by the dam and intake structures, and take usual open-water precautions.
