*** 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
Bologna, in the Emilia‑Romagna region, is inland and not situated on a large natural lake, but several artificial reservoirs and small natural basins lie within driving distance in the Apennine foothills. Water temperatures in these lakes tend to be cooler than coastal waters and vary by season, depth and local weather. Typical surface readings in spring range from about 8–18 °C (46–64 °F), in summer from roughly 16–26 °C (61–79 °F) at the warmest shallow spots, in autumn from 10–18 °C (50–64 °F), and in winter can drop to near freezing 0–6 °C (32–43 °F) in sheltered or high‑altitude basins. Deep reservoirs remain noticeably colder even in summer.
Swimming is possible at a number of designated spots around Bologna’s nearby lakes during the warmer months, and some recreational areas provide beaches, supervised zones or facilities for non‑motorized water sports. However, access and bathing rules vary: certain reservoirs restrict swimming to protect drinking‑water supplies or for safety reasons (currents, depth near dams), while others only permit swimming in marked areas with lifeguards. Visitors should check local signage and municipal rules before entering the water, and be mindful that cooler temperatures and sudden depth changes can affect safety even on warm days.
