Yes, exactly, temperatures have already dropped in northern Italy and in part of the center, thanks to the rains, while in the south they will drop from Friday. However, it remains a very hot August and in general the summer of 2021 was among the hottest in Italy, not in the north but in the center (especially the Adriatic side) and in the south. In Sicily and much of Calabria, I suspect that summer 2021 may be the hottest, beating 2003 or 2017, depending on the area (summer 2003 hit the western slopes the most, while summer 2017 was more generalized and with records even at high altitude).
