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

Stagno di Cagliari is a shallow coastal lagoon on the southern shore of Sardinia whose water temperatures follow the Mediterranean seasonal cycle. In winter the surface water typically sits around 10–14 °C (50–57 °F), rising in spring to roughly 15–20 °C (59–68 °F). Summer warming can push shallow areas into the low to high twenties Celsius, commonly 22–28 °C (72–82 °F) and occasionally higher in very hot spells, while autumn sees a gradual decline back toward the spring range. Because the lagoon is shallow and brackish, temperatures can vary locally and warm faster than the nearby open sea, especially in late summer.

Swimming in Stagno di Cagliari is generally not encouraged and often restricted because the waters lie within a protected regional park and important bird habitat. Conservation rules, the presence of saltworks and wildlife, and variable water quality mean that bathing is usually discouraged to avoid disturbance and potential health risks. Visitors seeking to swim typically use the nearby coastal beaches where open-sea bathing is permitted and managed, while the lagoon itself is mainly valued for wildlife observation, environmental education and regulated recreational uses rather than for swimming.
