Alpine zones (Dolomites, Courmayeur) cool rapidly after sunset; even in July you'll want a light sweater. Tuscan and Umbrian hill towns run warmer by day, cooler at night; coastal Tuscany (Forte dei Marmi) is breezier and less humid than inland Florence.
Southern islands—Sicily, Sardinia—stay warm into November, with sea temperatures often swimmable through early fall. Plan sailing days with a buffer: the Maestrale and Scirocco winds can shift sea states quickly; captains will adjust routes accordingly. In shoulder seasons, mornings can be crisp and afternoons bright—layering is the safest strategy.
