Venice is located in the north of Italy, relatively close to the Alps. This means that the climate varies a lot from one season to another and could be a determining factor, depending on when you want to visit the Serenissima.
Summer in Venice
In summer, temperatures in the city are high during the day and at night are cooler. If you are sensitive to cold, we recommend bringing a summer jacket for the evenings. There could also be occasional summer storms, although these are rare.
During the day, it can get quite hot, but luckily the streets in Venice are very narrow and therefore provide shade. If you are staying in Venice for more than a weekend, we suggest heading one morning to Lido di Venezia, which is a long sandbar very close to Venice where you will be able to sunbathe and swim in the Adriatic Sea, which is a nice temperature during July, August and September.
If you can choose when to visit Venice, we would definitely recommend the summer, since the days are longer, the weather is very agreeable and you can make the most of the Adriatic Sea.
Spring and Autumn in Venice
You will need to pack warm clothes if you visit Venice during spring and autumn, since it can get very cold when cloudy and windy. Moreover, spring is when it rains most in this part of Italy.
Winter in Venice
In winter the average temperature is below 50°F (10°C). It can get extremely cold and it snows quite frequently. We only recommend visiting Venice during the winter months if you want to witness the Venice Carnival or if you can only can’t go any other time of the year.
