Mediterranean cruises in May

One of the strongest months on the whole sea: long days, highs in the 70s °F (21–26°C), gardens in bloom and lines at the Vatican and the Acropolis that are long but not yet punishing. Western Med and Adriatic itineraries shine. The Greek islands are pleasant for walking, though the water won’t feel properly warm until June.
