*** 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 Monterosi, a small volcanic lake north of Rome in Lazio, typically shows seasonal water temperatures that reflect its modest depth and Mediterranean climate. In winter the surface often falls to roughly 4–9 °C (39–48 °F). Spring brings a gradual rise to about 9–18 °C (48–64 °F) as air temperatures warm and sunlight increases. Peak summer temperatures commonly reach around 20–26 °C (68–79 °F), making the water comfortably warm on hot afternoons, while autumn sees a cooling trend back to roughly 12–18 °C (54–64 °F) before winter chill sets in. Local variations can occur from year to year depending on rainfall and seasonal heatwaves.
Swimming at Lago di Monterosi is generally possible, and people do enter the water for recreation in warmer months, but it is not a heavily managed public bathing facility. Whether swimming is permitted at a given access point can depend on local municipal rules, private property boundaries, and occasional restrictions tied to water quality or conservation measures; there are also few formal lifeguard services. Visitors are advised to check on-site signage or with local authorities before swimming and to be mindful of water quality advisories, shoreline conditions, and ecological protections that can affect access.
