Florence city, like the rest of Italy, has a Mediterranean climate, which means that in the summer months, in the driest months, the city has a rainfall of less than thirty milliliters. The month with the most rainfall has three times as much rainfall as the driest month. Due to the influence of the Mediterranean, the daytime temperatures in Florence are quite high and less extreme weather conditions occur. The summer months of July and August are often very hot with days averaging thirty degrees Celsius. Many Florence tourist attractions respond to this with good air conditioning, but the Duomo with its narrow stairs, it is better not to climb in direct sunlight. The best time to visit Firenze is therefore in spring or autumn, where you will still have sunny days but without the oppressive heat of the summer months.
