Best Time for The Dodecanese: Rhodes & Kos
Last updated:
Sweet spot: March, April, May. Computed from NASA POWER climate normals across the route's overnight towns, balancing temperature, rainfall and daylight.
💡 Good to know
- Rhodes–Symi sailings run daily in the main season, while the direct morning Symi–Kos service normally skips Thursday. Visit Lindos' acropolis before the heat and verify both dated ferries before booking.
- The meltemi cools what the sun overdoes; Rhodes' walled town stays shaded and Symi's day-trip hours are best avoided with an overnight stay.
