Mykonos Weather – May

May is a great time to visit Mykonos, as the warm summer season kicks off.

You can expect sunny blue skies with little or no rain. Daytime temperatures reach an average high of 23°C (73°F) and a low of 14°C (57°F) in the evenings.

Warmer weather conditions in May are good for sunbathing, swimming, snorkelling and scuba diving.

May is also a good time to explore the island on foot, bicycle or motorcycle, and to discover the preserved ruins of classical antiquity on tiny Delos Island, just a short boat ride away.

May is a good time to avoid the summer crowds and take advantage of cheaper off-season flights and hotel rates.
