Mykonos Weather – August

August is an excellent time to visit Mykonos with hot summer weather.

You can expect hot, sunny days with little or no rain. Daytime temperatures get much warmer climbing to an average high of 29°C (84°F) and a low of 21°C (70°F) in the evenings.

Weather conditions in August are excellent for sunbathing, swimming, snorkelling and scuba diving.

Away from the beach, this is also a good time to explore the island on foot, bicycle or motorcycle. Don't miss the preserved ruins of classical antiquity on tiny Delos Island, just a short boat ride away.

August is peak season in Mykonos, with a commensurate rise in hotel rates and more crowded entertainment venues.
