What should I wear for an evening Bosphorus cruise or waterfront walk in Istanbul?

In Istanbul, rain can make it feel cool even during the day and while standing under cover, so bring one extra lightweight layer for time by the Bosphorus.

Bosphorus waterfront areas can become windy and cooler in the evening than central streets. Lightweight trousers are useful for evenings and rainy weather even when daytime temperatures are warm.

During the warm season, a denim jacket is usually unnecessary for an evening on the Bosphorus, as genuinely cool nights are still uncommon. A light shirt or wrap is a more practical backup.
