Turkey · Ships call at Istanbul, Turkey
Warm and mostly dry
Istanbul in September offers pleasant temperatures, with highs around 77°F and comfortable lows near 66°F. Rain is uncommon, with only about 2 rainy days expected across the month, ideal for beach days and shore excursions. Warm and mostly dry.
This is one of the most popular months to visit Istanbul, so book shore excursions early. The top snorkeling spots and tours sell out fast. Lightweight layers work well: a light cardigan for evenings on deck and breathable tops for port days cover most conditions.
