What to Wear in Istanbul during July?

During the summer it is best to wear light airy cotton clothing with a hat and sunblock since most days will be sunny.

A light sweater will come in handy for the cooler late evenings or early morning hours.

Sundresses and knee-length skirts/shorts and t-shirts and jeans are ok in Istanbul, however when visiting a Mosque, women must cover their hair, upper arms, shoulders, and knees. 


Things to Do in Istanbul in July

Since the weather should be quite nice, this would be an excellent time to consider taking a pay-what-you-wish walking tour in Istanbul.

If you're looking for a romantic night out, consider a Bosphorus Dinner Cruise or perhaps even a sunset cruise, as the temperature is always cooler on the water when the sun goes down.

Alternatively, you might also want to experience a Whirling Dervishes show to see one of the most well-known cultural dances in Istanbul.

For family fun during the day, consider enjoying a typically unobstructed view of the city from Galata Tower. Alternatively, you might also wanrt to consider going on a zipline adventure!
