Italy might be the world’s most celebrated tourist destination, most suitable time to go to southern Italy seems to be May to early June and late September to early October when you can still enjoy good weather but will be able to avoid the largevacationing crowds and won’t have to book too far in advance to get hotel accommodation or flights. Certainly it is ideal to base your itinerary on the region you will be visiting as there may be specific events you want to attend, or a particular sport which only takes place in one season.
