The weather becomes warm during the day and pleasantly cool at night, while rain showers are getting rare. You can expect average high temperatures between 18 C (65 F) and 27 C (81 F).
See below for a yearly overview. Another advantage of visiting Istanbul during spring is that you can witness the awakening of the city and Mother Nature. The city becomes more vivid (with the reopening of the terraces) and colorful (with the blossoms of the flowers in general, and the famous tulips in particular).
