*** 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
Perugia, the hilltop capital of Umbria, sits a short drive from Lake Trasimeno, the region’s largest lake and the main local spot for open-water swimming. Because Trasimeno is relatively shallow, its surface warms and cools more quickly than deep alpine lakes: typical winter temperatures range from about 6–10 °C (43–50 °F), spring from roughly 10–18 °C (50–64 °F), summer usually between 20–28 °C (68–82 °F) with occasional heatwave peaks near 30 °C (86 °F), and autumn cooling back toward 10–20 °C (50–68 °F). These averages vary year to year with weather and wind conditions, and surface readings can be warmer than deeper water.
Swimming in Lake Trasimeno is generally permitted and popular during the warmer months, with municipal beaches and bathing areas equipped for recreational use. The lake’s shallow, slow-moving water makes it inviting for swimmers and families, but local authorities periodically restrict bathing if water quality deteriorates—most commonly due to algal blooms or runoff after heavy rains—so swimmers should heed posted notices. Safety considerations such as buoyed swimming zones, lifeguard presence during the peak season, and awareness of changing weather also influence when and where people swim.
