April to June and September to October offer the most comfortable weather across Istanbul and Cappadocia, avoiding both summer heat and winter cold. Antalya’s beach season runs May through October, with July and August being warmest but also busiest and most expensive. December to February is coldest but suits travelers focused on Istanbul’s indoor sights and lower prices.
Turkey’s weather varies more by region than most single-country destinations, Istanbul, Cappadocia, and Antalya each have a slightly different ideal window, so the best time to go depends partly on which route you’re booking.
Turkey Weather by Month

Best Time by Trip Type
If your route is Istanbul and Cappadocia, April to June or September to October give the most comfortable conditions for walking tours and the Cappadocia hot air balloon experience, which depends on calm morning weather. If Antalya’s beaches are the priority, May through October works, with June and September offering warm water without the peak-season prices of July and August.

Cheapest Time to Book
December through February brings the lowest package prices, particularly for Istanbul-focused trips, though it’s not suited to an Antalya beach stay. September and October offer a strong middle ground: still-warm weather across most of the country at meaningfully lower prices than the July to August peak.
