Best time to visit Siena
Peak Season (June–August)
Summer in Siena is lively and vibrant, especially with events like the famous Palio horse race on July 2 and August 16, which draws large crowds. Expect warm weather, with highs between 27–35°C (81–95°F), perfect for outdoor activities but busy with tourists. Book accommodations early, as prices and availability are affected by festival crowds.
Off-Season (November–March)
Ideal for a quieter, budget-friendly experience. Winters are mild but can be chilly, with lows around 3°C (37°F) in January and higher rainfall, particularly in November. While major events are fewer, Siena’s local charm and cozy atmosphere make this a peaceful time to explore.
Festival considerations
Besides the Palio, summer features the Siena Jazz Festival in July. Fall is a great time for art lovers with the Siena Art Weekend in September, and December brings festive Christmas markets to the city.
