Mestre shares Venice's climate: hot and humid summers, cold and foggy winters, with spring and autumn offering the best balance of mild weather and fewer crowds. Summer brings outdoor events to Parco San Giuliano, including the Heineken Jammin' Festival (a major multi-day rock event in early July) and the Electro Venice Festival for electronic music fans. Venice's famous Carnival, held in the weeks before Lent, spills over into Mestre with its own celebrations and costumed parades.
