Mediterranean cruises in September
Arguably the sweet spot for the whole region. Sea temperatures stay near their summer peak, highs ease into the low 80s °F (27–28°C) and family crowds vanish once European schools reopen in the first weeks of the month. Every sub-region works, and the grape harvest is underway from Tuscany to the Greek islands. Fares stay fairly high because demand is strong.
