Siena in May

April through June gives you perfect weather without summer crowds. The countryside explodes in green, and restaurant terraces reopen. October offers the same sweet spot — warm days, cool evenings, and the grape harvest in full swing. July 2nd and August 16th mean Palio madness. The city quadruples in size, hotel prices triple, and you'll need reservations months ahead. But witnessing the race is unforgettable — if you can handle the chaos. Winter brings fog and rain, but also solitude. The Duomo's interior glows under artificial light, and you'll have those narrow streets mostly to yourself. Many restaurants close for vacation in January and February.
