Climate and weather in Turkey Turkey’s Aegean and Mediterranean coasts have very hot and dry summers, and wet, mild winters. The coastal towns more or less shut down between October and April. Winter in Istanbul and Cappadocia can be very cold with a dusting of snow. During the peak tourist season (between June and September) mosquitoes can be a problem. Spring and autumn are the best times to visit, as the climate is still hot, but not unbearable. Mountains close to the coast prevent Mediterranean influences from extending inland, giving the interior of Turkey a continental climate with distinct seasons. In Bodrum and Fethiye, the temperature is about 30ºC during the summer months, and generally over 10º during the winter. Sea temperature never falls under 16ºC. Return to main Turkey page
