is best, autumn next, then summer, last winter.
Spring (April through mid-June) is prime because the weather
is moderate throughout the country, the days are long, and
the tourist rush hasn't begun. April can be rainy, though.
Autumn (mid-September through October) is second best with
mostly mild weather, but the days are shorter, and rain may
begin again in October.
Summer (mid-June through mid-September) is quite hot in five
of Turkey's seven distinct climatic regions, though usually
rainless, and cool inland in the evenings.
Winter (November through March) is chill and rainy everywhere
except the southeast, but with lower prices and fewer tourists.
