Weather in Siena

Best time to visit

Summer temperatures vary between 25°C-35°C (77°F-95°F) in Siena and July and August brings key events such as the Palio horse race and International Jazz Festival. Autumn brings more comfortable temperatures whilst the city is still brimming with events and arts festivals. But if you're in the city in October, pack your waterproofs and wellies as showers are frequent and temperatures begin to drop. Winters are very cold and temperatures drop to single digit figures. Meanwhile, spring is a pleasant time to visit when the city's flowers are beginning to bloom and many street festivals get into full swing.
