Water Temperature: Daily Trends, Historical Records, and Forecast
❌ As of today, the minimum water temperature ranges from 50°F (10°C) to 54°F (12°C). The water is slightly warmer, but still cool for most people. Swimming in such conditions is possible, but for most people, the time spent in the water should be limited to avoid hypothermia. Even experienced swimmers may feel discomfort if they stay in the water for too long. To improve comfort and safety, a wetsuit 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.

*** 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 San Giuliano, a reservoir near Matera in Basilicata, shows noticeable seasonal variation in water temperature. In winter surface temperatures are commonly around 6–12 °C (43–54 °F), rising through spring to roughly 10–18 °C (50–64 °F). In summer the shallows often warm to 20–26 °C (68–79 °F), and during heat waves some areas can reach 27–28 °C (81–82 °F); autumn cooling typically yields 14–20 °C (57–68 °F). Local conditions such as depth, inflows from the Basento river, wind and daily sunshine mean that surface readings can differ significantly from deeper water and from one part of the lake to another.
Swimming at Lago di San Giuliano is not organized like at a managed beach: while people do sometimes bathe informally, the basin is a managed resource used for irrigation, flood control and habitat protection, so official bathing areas and services are limited. Authorities may restrict or discourage swimming to protect water quality and natural habitats and to reduce safety risks from submerged hazards, sudden depth changes and boat traffic. Visitors should check local signage and rules, be aware there are usually no lifeguards, and verify recent water-quality information before entering the water.
