Venice — Water Temperature, Sea Conditions & Trends

Water Temperature: Daily Trends, Historical Records, and Forecast

✅ As of today, the minimum water temperature is above 82°F (28°C). This is very warm water, which may feel almost hot to most people. Swimming in such conditions is perfect for those seeking relaxation and comfort in the water. These waters are often preferred for relaxation in hot weather, as the water temperature does not cool the body significantly. However, it is important to remember that in such warm waters, caution is necessary, as prolonged exposure without rest can lead to overheating.

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.

Annual Water Temperature Trend

Venice sits within a shallow lagoon on Italy’s northeastern coast, and its water temperatures reflect the interplay of shallow seas, tidal exchange and nearby Adriatic influence. Across the year the lagoon is cool in winter, typically around 6–9 °C in January and February, and gradually warms through spring to roughly 9–15 °C by April and May. Early summer sees a noticeable rise, with water often reaching about 18–22 °C in June and peaking in midsummer at approximately 22–26 °C in July and August. Temperatures then decline through September and October, commonly falling to 18–20 °C before dropping back toward winter levels. Local conditions such as shallow depths, weather patterns and occasional freshwater inflow can cause short-term variation from these averages.
