*** 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 Porta, a small freshwater lake in Tuscany, typically experiences seasonal surface temperatures that reflect the region’s temperate climate. In winter the water often cools to roughly 4–8 °C (39–46 °F), while spring brings gradual warming to about 8–16 °C (46–61 °F). Peak summer temperatures commonly reach 20–26 °C (68–79 °F), making the warmest months the most comfortable for swimming. During autumn the lake usually drops back to around 12–18 °C (54–64 °F) as air temperatures fall and rainfall increases. Local factors such as depth, shading, inflows, and wind can shift these ranges somewhat from year to year.
Swimming at Lago di Porta is generally possible during the warmer months when surface temperatures are pleasant, but it depends on local rules and environmental conditions. Many natural lakes in Tuscany permit bathing, yet access can be limited by private ownership, nature protections, water quality advisories (for example after heavy rain or algal blooms), or safety concerns like sudden depth changes and lack of lifeguards. Before entering the water it is sensible to check posted signs or municipal guidance about permitted swimming areas and recent water-quality information; when conditions are suitable, summer swimming is a common recreational use of the lake.
