Climate of Istanbul

The climate in Istanbul is generally similar to Marmara region; summer months are warm and humid with very little rain especially between July-August, winter months can be cold and wet with some snow but not that much extreme as some other areas of Turkey. Spring and autumn are mild and this would be the best time for visitors.

Istanbul is so huge as an area and it has so many topographic diversities that you can experience several different sub-climates in the same city. For example, Bosphorus Strait and surroundings are dominated by the Mediterranean climate (dry summers and mild and rainy winters) but to the north you can notice a Black Sea climate (mostly rainy). And meanwhile you can have a Balkan climate to the west (cold winters and snow) there is a Anatolian Continental climate to its east (hot summers and cold winters). You can even have completely different climates in the same day; while snowing in one area you can notice the sun shining (but cold of course) on another part of the city.


While the astrological spring starts on March 21, in Istanbul spring generally starts somewhere mid-April. 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).


Summer, from mid-July to mid-September, is hot and often humid. Average daily highs are around 28 C (80 F), with especially in August peaks over 30 C (82 F).

While most Istanbulites escape the summer heat and head for the islands or the coasts, the summer months see a huge influx of tourists. Expect longer queues and take the necessary precautions to protect yourself from the sun (and air-conditioners). The biggest advantage this season has to offer is the ideal Bosphorus cruise conditions.

Fall (Autumn)

Fall or autumn lasts until the end of October, sometimes even mid-November. Temperatures are most of the time back to human levels (23 C or 70 F), but be prepared for surprises! One day can be hot and dry, while the next can be much cooler (15 C or 60 F) with short but intense rain showers.


Generally speaking winters are cold, with average day temperatures between 8 C (48 F) and 12 C (54 F). Snow showers are rare, but it rains frequently (see statistics below).

Now I can hear you think, “So, what are the advantages then?” Well, you can enjoy reduced hotel prices, visit all the tourist attractions much more relaxed, and experience the year-end celebrationsand decorations.
