March-April can often be rainy, so dress in layers and be prepared for some spring showers. While in May it really starts to get warm! Summers in Florence are very hot and quite humid. Daily highs in July and August average 90 degrees F, or in the 30s C. Be sure to bring a hat and periodically dip into stores and cafes to drink plenty of water if you get too hot while sightseeing.
