Water Temperature: Daily Trends, Historical Records, and Forecast
❌ As of today, the minimum water temperature ranges from 47°F (8°C) to 50°F (10°C). This is still cool water, suitable only for experienced swimmers or those accustomed to cold water. Swimming in such conditions is possible, but not recommended for prolonged periods. Extra caution should be taken during extended exposure, as the cold water can cause heat loss and lead to hypothermia. For added comfort, special clothing can be used. It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.

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
The so-called Lake of Arno refers to sections of the Arno River in Tuscany where the flow widens into calm, lake-like areas, especially near artificial reservoirs such as those close to La Penna and Levane. These basins collect water from the river and surrounding hills, creating stretches that resemble small lakes. The water temperature in these areas changes significantly with the seasons. In winter, it averages between 5 and 8°C, in spring it rises to 12–16°C, and during summer it reaches 22–26°C, with shallower parts occasionally warmer. In autumn, it cools again to around 14–18°C.
Swimming in the Arno’s lake-like reservoirs is technically possible but regulated. In some sections, swimming is discouraged because of safety and water management purposes, while in others locals occasionally bathe or kayak during summer. The water quality varies depending on rainfall and flow, but it is usually clean enough for recreational use in calmer stretches. Overall, these areas offer scenic natural beauty and refreshing conditions, especially on hot Tuscan days.
