*** 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 Fondi is a shallow coastal lake in Lazio whose surface temperatures respond quickly to seasonal change. In winter the water commonly sits around 8–12 °C (46–54 °F), rising through spring to roughly 12–20 °C (54–68 °F). Peak summer temperatures often climb into the low to high twenties, commonly 22–28 °C (72–82 °F) on warm days, while autumn sees a gradual cooling to about 14–20 °C (57–68 °F). Because the basin is relatively shallow and sheltered, it can heat up faster than deeper inland lakes and is also prone to stratification effects, algal blooms and fluctuating clarity depending on rainfall and agricultural runoff.

Swimming at Lago di Fondi is possible in practice, but access and suitability vary. Parts of the lake lie within protected natural areas and reedbeds that are important for birds and freshwater habitats, and certain zones are restricted to conserve wildlife or for safety. Water quality can vary seasonally, so local authorities post guidance and some stretches are more commonly used for bathing and water sports than others. Visitors should follow signage, respect protected areas and if in doubt consult local information about water quality and permitted activities before entering the water.
