In earlier times, the month of October was considered the beginning of slow season, since prices would fall and tourists would begin to fly back home. Those days, however, have become history in most tourist areas of the country. 

When it comes to tourism, both April and October are considered two of the busiest months in Italy and one should not assume that, if travelling then, their holidays will be quiet; on arriving you will be surprised to know that tourists are still very much around. June or July have more tourists compared to October, however crowds are attracted to the pleasant weather of the country during this month, and to the relative drop in the prices of hotels and flights.
