Weather Overview for Istanbul
The transcontinental city of Istanbul is the largest city in Turkey (sixth largest in the world), with a population of 14.1 million. Straddling the Bosphorus strait between the Sea of Marmara and the Black Sea, the historic and economic hub of the city falls within the European part of Eurasia, while over a third of the population live on the Asian or Anatolian side of the strait.
Istanbul’s climate is a mixture of Mediterranean, humid subtropical, and oceanic. And, thanks to its size and diverse topography, Istanbul also exhibits microclimates. At different times of the year some parts of the city will benefit from more rainfall, have higher levels of humidity, or be warmer than others.
Summer in Istanbul falls between June and September. This is the dry season, with less than 50mm of rainfall over 8 days each month. The days are long and hot, with up to ten sunshine hours, clear skies, low wind speeds, and temperatures averaging around 25C. With average highs of 28C in July and August, visitors should expect temperatures to exceed 30C for several days at the peak of the season. Humidity is relatively low in Istanbul during the summer months, which does help to make the heat more bearable.
Istanbul in the autumn is still quite pleasant. Temperatures gradually begin to fall and precipitation levels increase, but it should remain relatively warm. The average temperature in October is 16C, with highs of 19C. Higher rainfall averages, with 100mm of rainfall over 13 days expected in November, however, mean visitors are likely to see some prolonged showers. With increased precipitation, expect cloudy skies for at least part of the day and foggy, overcast mornings.
It’s cold and wet in Istanbul during the winter months, between December and March. Temperatures fall to below 8C, and it isn’t uncommon for it to freeze overnight. There’s the possibility of a few inches of snow by February, and rainfall averages are at their highest (100mm of rainfall is expected over 17 days in December). Wind speeds also really pick up at this time, which ensures low temperatures feel even cooler.
Spring falls between the end of March and May. As summer approaches it begins to warm up, with highs of 20C in May. But at the start of the season temperatures are still quite low (just 12C on average in April) and rainfall averages are high (in April, around 60mm is expected over 11 days) so expect showers and even the occasional thunderstorm. Days tend to start off cloudy and overcast, though by the end of May wind speeds are at their lowest and skies start to clear, so visitors can begin to appreciate the warmer temperatures.
