Most of the time, May is sunny with the daily sunshine at close to 7.5 hours. The days are warmed to pleasant 21.1°C (70°F) and the nights are above 10°C (50°F).
Beware; May is the peak tourist season, and the crowds adorn the length and breadth of Venice.
A scarce rain does not discourage visitors from participating in the regatta and rowing races. It is a fantastic sight with almost 1500 boats of all shapes and sizes occupying every waterway, including the Grande Canal.
