Istanbul in June

When to go

The Turkish State Meteorological Service's Istanbul table puts June between May and July for both temperatures and monthly precipitation, and it also lists the average number of rainy days, so check the figures here when you plan what to pack. GoTürkiye's Istanbul events page lists upcoming cultural and artistic events across the city, so look there for listings that fall on your dates. Check the Turkish Ministry of Foreign Affairs' visa page and the State Department's page for Turkey for the entry rules that apply to your passport.
