*** 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
Around Grosseto and the Maremma hinterland, lakes and coastal lagoons tend to be shallower and more sheltered than open sea, so their temperatures follow a seasonal pattern: in winter surface water typically sits around 6–10 °C (43–50 °F), spring sees warming to roughly 10–18 °C (50–64 °F), and summer often brings the warmest conditions, about 20–26 °C (68–79 °F) in deeper inland lakes and 22–28 °C (72–82 °F) in shallow coastal ponds and lagoons. Autumn temperatures generally fall back into the 12–18 °C (54–64 °F) range. These figures are approximate and vary with depth, shading, freshwater inflow and wind; shallow, sheltered bodies warm fastest and cool fastest.
Swimming is commonly possible in many of the lakes and lagoons around Grosseto, but access and suitability depend on local regulations, water quality and safety. Some sites are popular for informal bathing in summer when temperatures are most comfortable, while other areas are protected reserves or privately owned and may prohibit swimming to protect wildlife or for safety reasons. Water clarity and currents are usually milder than the sea, but swimmers should heed local signage, seasonal advisories and lifeguard presence where available before entering the water.
