Temperatures in Venice, the largest city in the Veneto Region, are much more moderate than in Florence or Rome. But personal experience tells me that when it's moderately hot in Venice, you swelter. It's the humidity; Venice is classified as having a Humid subtropical climate. There are between 6.5 and 9 precipitation days in most months, the exception being August, with fewer than two precipitation days.
Unlike the other cities of Italy's "Big Three," Venice's rainfall is pretty well distributed throughout the year, totalling just over 32 inches on average. You'll find thunderstorms, particularly in Spring and Autumn. The biggest holiday periods in Venice feature its worst weather: Christmas (wet and cold), Carnevale in early Spring (foggy and cold), and Venice Film Festival time in August (hot and humid).

The best times of the year to visit Venice are from May through early June, then September and October.
Venice's high water, or Acqua Alta, generally occurs in spring or fall. November seems to be the worst time for high water, which peaked at high levels in that month in 1996 as well as 2012. Today, over 60 occurrances of high water are expected each year.
Venice has a system of warnings for residents and visitors, and inexpensive rubber boots are available for sale or are given out by hotels to guests when acqua alta occurs. For more, see: The Acqua Alta FAQ and for the tidal charts for the current week, see: Centro Previsioni e Segnalazioni Maree.
Venice is one of the best walking cities in the universe. As a sea power, the wealth of ideas it brought back from its excursions, especially to the east, resulted in a city whose art and arcitecture is unique, interesting, and diverse. Wander the city, get away from Piazza San Marco and the tourists and squeeze through the narrow passageways for a day.
When you tire of Venice's restaurants, you may wish to travel to the home of a "Home Chef" and learn some of Venice's secrets while chowing down on the local foods. Check out the opportunities: Where to eat in Venice, Italy from BonAppetour.
Then, when you want it all explained to you, take a tour. Below are some of our suggestions.
If you want a highly rated place to stay in the Castello district, a non touristy part of Venice, the Queen House Garden is a bargain. Close to the train station in the Cannaregio is the B&B Aquavenice. For elegance at a good price, try the Hotel Al Ponte Mocenigo.
It takes a lot of exploring to put Venice in perspective. You might want to stay in a vacation apartment or house, expecially if it has an altana, a typical Venetian rooftop terrace, great for when the weather is warm and you want a view over the city and lagoon: Venice Vacation Rentals. Staying a week in Venice isn't a bad idea.
Escaping the tourist hordes? Perhaps you'd rather stay at the beach: Venice Lido.
