What should I pack for a holiday in Istanbul in May?
You can definitely break out your summer wardrobe for a trip to Istanbul in May but add a few light jumpers in case of cooler days. If you plan to visit the Blue Mosque there is a dress code to adhere to so pack long trousers or a long skirt, a top that covers your shoulders and, for women, a scarf to cover your hair.

The temperature reaches around 22℃ during the daytime in May, falling away to 15℃ at night. The UV index will be high at this time of year, so protection against skin and eye damage is needed. Try to limit exposure between 10am and 4pm.
