May to October is an ideal time to visit with sunny days and warm waters. July and August can be very busy. Visit in summer for the annual Dubrovnik Summer Festival, a 45-day-long cultural event with live plays, concerts, and games. Winters can be quiet and January is best avoided with many hotels, restaurants, and shops closed for the month. February 3 is St. Blaise’s Day, Dubrovnik’s patron saint. The city celebrates with parades and festivities, although the rest of spring can be quiet until Easter.
