Traveller notes on Korčula in May
Notes from nearby Split (83 km away)
Korčula doesn't have its own notes for May yet — these are about Split, close enough to share the season.
Split's forum puts May in the low-to-mid 20s°C, often warm enough for shorts throughout the day, though the Adriatic coast can just as easily turn a whole week cloudy and cool. Regulars flag the sea as still on the cool side early in the month, warming enough to swim comfortably by the end of May.
Other months in Korčula
Korčula's forum calls July good swimming weather but the busiest stretch of the year — several regulars suggest September instead for a quieter island that's still warm enough to swim and sit out in the evening. Worth weighing if crowds matter more to you than guaranteed heat.
