Santorini: May Weather


Santorini Weather in May

May is a great time to visit Santorini, as the warmer summer season kicks in.

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 17°C (62°F) in the evenings.

Weather conditions in May are good for sunbathing, swimming, snorkelling and scuba diving. This is also a good time to explore the island on foot, bicycle or motorcycle. Don't miss the preserved ruins of classical antiquity at Ancient Thera and the nearby Minoan Bronze Age settlement of Akrotiri or the narrow picture-perfect alleyways of Firá and Oía.

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