This page provides information on the current water temperature in the Sesia River, trends, monthly ranges and the forecast for the coming days.
Current Water Temperature
Water Temperature in the Sesia River today is 21.3°C.
Water Temperature: Daily Trends, Historical Records, and Forecast
✅ As of today, the minimum water temperature ranges from 68°F (20°C) to 74°F (23°C). The water is warm and pleasant for swimming, and in this range, one can stay in the water for extended periods without the risk of hypothermia. This is the ideal temperature for relaxation, swimming, and water sports. Families with children, as well as outdoor enthusiasts, will enjoy swimming and time spent in the water. For most people, this is the optimal temperature for a comfortable beach experience. 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
The Sesia is an Alpine river in Piedmont whose water temperature varies strongly with altitude, season and localized flows. In winter the river is cold, often ranging around 0–6 °C (32–43 °F) in many stretches, while spring temperatures are typically 4–12 °C (39–54 °F) as snowmelt keeps flows chilly. In summer the lower reaches can warm to roughly 14–22 °C (57–72 °F) on hot, low-flow days, though upstream and shaded sections remain noticeably cooler. Autumn sees a progressive drop, commonly 8–14 °C (46–57 °F). These figures are approximate averages: temperatures rise downstream and on slow, sun-exposed stretches and remain lower near the source and after rainfall or dam releases.
Swimming is permitted in much of the Sesia and the river is used recreationally for bathing, but it is not uniformly safe everywhere. Strong currents, rapid depth changes, submerged rocks and occasional sudden increases in flow from hydropower operations create hazards; cold water can also cause hypothermia even in summer. Local regulations, signage and seasonal monitoring determine permitted spots, and lifeguards are generally absent. For casual swimmers, summer in lower, calmer sections is the most comfortable option; more caution, flotation aids or a wetsuit are advisable, and in winter or during high spring runoff swimming should be avoided.
