Italy's peak season
The best time to visit Italy is the peak season, which are June, July and August. These summer months are typically characterised by warmer weather, longer daylight hours and a variety of vibrant events and festivals.
Coastal areas such as the Amalfi Coast, Cinque Terre and Sicily are becoming especially popular for their superb beaches and scenic towns. So if you’re planning to visit popular areas, especially beach resorts, avoid July and especially August when the weather can be too hot and the crowds at their most congested.
In August, when most Italians are on holiday, you can expect the crush to be especially bad in the resorts, and the scene in the major historic cities – Rome, Florence, Venice – to be slightly artificial, as the only people around are fellow tourists. It is advisable to pre-book tickets and plan your visit early in the day to avoid long queues.
Italy shoulder season
The nicest time to visit, in terms of the weather and lack of crowds, is from April to May, and in September or October. If you’re planning to swim, however, bear in mind that only the south of the country is likely to be warm enough outside the May to September period.
"Shoulder" season is ideal for exploring the cities and countryside as the weather remains pleasant. It is the ideal time to explore Italy's magnificent gems such as the vineyards of Tuscany, the picturesque Dolomites and other historic sites without being crowded by tourists.
It's also much easier to find more affordable accommodation options and better deals at popular tourist destinations during these months.
