When to Visit Venice, Italy
Unlike central Europe which experiences frigid winter temperatures and sweltering summer heat, the Mediterranean city of Venice enjoys more mild temperatures throughout the year, ranging from the low 30s Fahrenheit in the cold winter months to the highs in the low 80s F in the summer.
The summer months are the high season in Venice, so while you will experience warm to hot weather, you will also likely encounter larger crowds during this season, especially at the most popular attractions and sights.
The shoulder season months of May and September-November are great times to visit this Adriatic city, when there are significantly fewer tourists crowding the sites and temperatures are still warm but more comfortable.
The winter months from December through late February are colder and not ideal for cruises, though if you don't mind wearing plenty of layers, this can be a great time to visit Venice to get great deals on hotels and admissions to attractions (as long as you know that some sites may close early during winter).
