What May is like
May is warm, sunny and calm, one of the least windy months of the year. Most places are open, boat trips to Kleftiko start running, and the beaches are close to empty. The sea is refreshing rather than warm, so swims are short early in the month and easier by the end.
Swimming and beaches
The sea averages 19°C in May. Refreshing: short swims. Swimming is for those used to cool water; the coast is better for walks and photos this time of year.
What to pack
Summer clothes, a light layer for evenings, sun protection; the UV is already high.
