*** 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 Fiastra, an artificial lake set within the Monti Sibillini area of Marche, has water temperatures that reflect its mountain-fed character. In winter the surface commonly sits around 2–6 °C (36–43 °F), while spring sees a gradual rise to roughly 6–14 °C (43–57 °F). Peak summer temperatures typically range from about 18–24 °C (64–75 °F), with shallow, sunlit bays occasionally reaching nearer 25–26 °C (77–79 °F) during heat spells. In autumn the lake cools again to approximately 10–15 °C (50–59 °F). Temperature can vary with depth, wind and inflow from cold springs, so even on warm days deeper or shaded areas remain noticeably cooler.
Swimming is permitted in many parts of Lago di Fiastra and is a popular activity in summer because of the scenic setting and generally clean water. However, access and allowed zones can be regulated by the local park authority to protect natural habitats and for safety around steep shores or near infrastructure such as dams. The lake’s relatively low average temperatures mean swimmers should be mindful of cold shock and hypothermia risks, enter gradually, and prefer sheltered shallows on hot days. Observing posted signs and local guidance helps ensure a safe visit.
