Mid-June, July, August and Mid-September are considered peak season in Tuscany, so be prepared to see big crowds in the squares and on the seaside, long queues at the museums and longer waiting lists to be seated at restaurants
The warmest months are July and August: temperatures rang between 27°C and 40°C. Keep in mind that in August many Italians literally run to the beaches to escape the heat of the cities and that many shops, restaurant and offices are therefore closed (in general for a couple of weeks, sometimes for the entire month).
If you want travel to Tuscany during summer but you are looking for a milder weather, choose June and September. They are characterized by warm weather but usually it’s not too hot, are fine to enjoy your holiday without being afraid of fainting under the sun.
