Venice, where it is

The climate of Venice is moderately continental, similar to that of the Po Valley, with cold and moist winters and hot and muggy summers, but slightly tempered by the Adriatic Sea.
Here are the average temperatures.

Precipitation is equal to 30 inches per year, and is well distributed over the seasons, with two relative maxima in spring and autumn, due to Atlantic depressions, and favored by the south wind ("scirocco") which brings moisture from the Adriatic Sea. Here is the average precipitation.

As well as the sirocco, Venice is sensitive to the bora, a cold wind blowing from the plains of Eastern Europe, especially in winter and spring. The bora sweeps the Venetian plain and the lagoon of Venice, although not with the same force that in Slovenia and in Trieste, where it is channeled through the mountains.
The phenomenon of the so-called acqua alta (high water) occurs in bad weather conditions, and is due to a combination of wind (the sirocco, which obstructs the flow of rivers into the sea) and tide (which raises sea level).

Winter, from December to February, is cold, damp and gray. The coldest months are, as in the Po-Venetian plain, January and December. At night, light frosts occur often enough. Fog is quite frequent, also in March. When the bora blows, due to the wind chill, the air feel colder than it actually is. During intense cold spells, the temperature can drop below 23 °F. Here are some temperatures recorded in recent decades: January 1985: 10.5 °F, December 2009: 12 °F, February 2012: 16 °F. Sometimes frost can occur also on early March, or on late November. During the coldest winters the lagoon can freeze, as happened in 1929, 1956, 1963, 1985 and in February 2012.

Frozen Lagoon of Venice

Snow is seen almost every year, but it's generally not abundant, because the bora is originally a dry wind, and generally brings at most light snowfalls, while when it snows in the western Po Valley (see Milan), here the south wind coming from the sea raises the temperature and brings rainfall.

Spring, from March to May, is a quite rainy and unstable season. There's no shortage of sunny days, but there may still be cold and foggy days (especially in March), as well as periods of bad weather and wind. Typically, starting from the second half of April, the temperatures become pleasant in a more stable manner, but the bora can sometimes still blow, lowering the temperature for a few days, even in May.

Summer, from June to August, is usually sunny, and is often also hot and muggy, but with the breeze that tempers a little the heat. Even on the hottest days, it is rare for the temperature to rise above 95 °F. In the afternoon, thunderstorms can break out, while sometimes the bora can blow, bringing a cool and cloudy weather.

Autumn, from September to November, is initially pleasant, with many sunny days, alternating with some rainy periods in September and sometimes in early October, and then gradually becomes more cold, cloudy and rainy.

Grand Canal

The amount of sunshine in Venice is good in late spring and summer, from May to August, when there are many sunny days, and it is still acceptable in September. In the rest of the year it is not high, because there are many cloudy days, and even some fog in the coldest months.
The sea, in the Venetian lagoon, but also along the coast of the Northern Adriatic Sea (see Jesolo), is warm enough for swimming in July and August, when the water temperature reaches 77/79 °F, while it is still a bit cool, but basically acceptable, in June and September.
Here are the average sea temperatures.

When to go

The best periods to visit Venice are spring and autumn, and in particular from mid-April to mid-June and the month of September; however, it is still possible that there are rainy days. July and August, and more rarely the second half of June, can be hot and sultry; in August there are many tourists (and many mosquitoes), and the lagoon doesn't always smell good.
