*** 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
Casalecchio di Reno, a town just west of Bologna in Emilia-Romagna, is bordered by an artificial lake on the Reno River that shapes part of the local parkland and recreation areas. Water temperature in the lake varies with the seasons: in summer it typically warms to about 20–26 °C (68–79 °F), offering the warmest conditions from late June through August; spring temperatures usually sit around 8–15 °C (46–59 °F) as the water recovers from cooler months; autumn sees a gradual cooling to roughly 10–18 °C (50–64 °F); and winter values often fall in the 3–8 °C (37–46 °F) range. Shallow and sheltered parts of the lake warm and cool more quickly, so local readings can differ from these general ranges.
Swimming in the Casalecchio lake is generally not promoted as an everyday recreational activity. Municipal rules and safety considerations—such as variable water quality, lack of permanent lifeguard coverage, boat and rowing traffic, and infrastructure not designed for public bathing—mean that free swimming is often discouraged or restricted; occasional supervised events or officially sanctioned areas may be allowed under specific conditions. Visitors interested in entering the water should check current local signage and municipal guidance, since water quality and permitted uses can change with season and management decisions.
