Best Time To Visit Istanbul > Weather, Temperature & Season

What is the best time to visit Istanbul?

April to June and September to October are the best times to visit Istanbul. Mild days in the high teens and low twenties, and the queues at Hagia Sophia and Topkapi are manageable.

July and August are the driest months of the year, and the warmest at about 28°C by day. They are also the most crowded and expensive.

December is the wettest month, and January the coldest at about 6°C. It snows on roughly 15 days a year, usually lightly. This is the cheapest time to come.

One thing that surprises people: Istanbul rains in most months, about 131 days a year spread thin. It is not the bone-dry Mediterranean summer you get down in Antalya.

More about Best Time to Travel to Istanbul

Istanbul Weather in April and May

April and May are the best pair of months in the year. April runs about 8°C to 16°C and May about 12°C to 21°C, with May the second driest month of the year.

April is the Tulip Festival, when the city's parks are planted out in millions of tulips, and the Istanbul Film Festival. 29 May marks the Conquest celebrations, with a light show on the Golden Horn.

Istanbul Weather in June and July

June and July are warm and dry. June runs about 17°C to 26°C, July about 19°C to 28°C, and July is the driest month of the year.

Humidity is the real issue, not heat: it is muggy rather than scorching, and eleven to twelve hours of daylight makes long sightseeing days possible. Peak prices start now. 15 July is a public holiday.

Istanbul Weather in August and September

August is the warmest month at about 24°C mean and 28°C by day, and September is nearly as good with fewer people. Locals leave the city in August, so traffic eases while tourist queues lengthen.

September runs about 16°C to 25°C and rain starts to return. The Istanbul Biennial, the contemporary art event, runs in September in odd years.

Istanbul Weather in October and November

October is the last comfortable month at about 12°C to 19°C. November drops to about 9°C to 14°C and turns properly wet, with rain on about 13 days.

29 October is Republic Day, with fireworks and processions across the city. The Akbank Jazz Festival also falls in November, and hotel rates drop sharply from mid-month.

Istanbul Weather in December and January

December is the wettest month of the year and January the coldest at about 6°C. Days run 6°C to 10°C in December and 4°C to 9°C in January, with under three hours of sun a day.

Snow falls on about four or five days in January, rarely heavily and rarely for long. This is the cheapest time to visit, the Bosphorus ferries are almost empty, and the hamams and the Grand Bazaar are at their best.

Istanbul Weather in February and March

February is still cold at about 3°C to 8°C, with four or five snow days. March turns the corner: about 5°C to 11°C, and by the end of the month the cold winds have gone.

Mornings in February are often foggy. Both months are cheap and quiet, and the tulips start appearing in the parks from late March.
