What August feels like

August is Sardinia at maximum volume. Italy holidays en masse around Ferragosto, the sea hits its warmest of the year, and the coast hums until late. It is hot, festive and busy, so book everything early, go to the beach at nine, and give the afternoon to shade, granita or a boat deck. Inland, Time in Jazz fills Berchidda and mountain villages offer cooler air an hour from the sand.
