Best time to visit Istanbul: weather, crowds and prices month by month

Short answer: late April to early June, and September to October. The weather is mild, the parks are green or golden, and you can walk all day without melting or getting soaked. But Istanbul has no bad season — only different ones. Summer brings long evenings on the water, winter brings empty museums and the lowest prices of the year. Here is what each month really feels like, from people who live here all year.

The four seasons

Spring (April – May): tulips and perfect walking weather

Highs climb from about 16°C in April to 22°C in May. In April millions of tulips fill Emirgan Park, Gülhane Park and the city’s roundabouts for the Tulip Festival, and the Istanbul Film Festival runs in mid-April. It is one of the busiest and most expensive times of year, so book early. Evenings can still be cool — bring a light jacket.

Summer (June – August): long evenings by the sea

Highs of 27–30°C with humid afternoons, almost no rain and sunsets after 8:30 pm. The sea reaches about 24°C, warm enough to swim on the Princes’ Islands or on a Bosphorus swimming tour. The Istanbul Music Festival (June) and Jazz Festival (July) fill the evenings. July and August are high season for families from the Gulf and Europe. Do sightseeing in the morning, rest at midday, and spend evenings on the water.

Autumn (September – November): our favourite

September still feels like summer (about 25°C, sea warm enough to swim), October is mild at around 20°C with golden light, and November turns cooler with the first rains. In odd-numbered years the Istanbul Biennial fills galleries from September to November. September and October are as busy as spring; November is usually the cheapest month of the year outside winter.

Winter (December – March): empty museums, low prices

Highs of 8–12°C, frequent rain and a few days of snow most winters — when the city turns magical. It is the season for hamams, fish restaurants (anchovies are at their best), warm salep on the ferries and museums with no queues. Apartment prices are at their lowest, except around New Year. Pack a waterproof jacket and good shoes for the slippery hills.

Month by month

January – February

The coldest months (highs around 9°C). Quiet, cheap and atmospheric; a chance of snow.

March

Still cool (around 12°C) and changeable. In 2027 it includes the end of Ramadan and the Eid al-Fitr holiday (9–11 March).

April

Tulip Festival and Film Festival. Fresh and green, around 16°C. Busy — book early.

May

Many locals’ favourite month (around 22°C). In 2027 the Eid al-Adha holiday falls on 16–19 May.

June

Warm (around 27°C), long days, the Music Festival. The start of swimming season.

July – August

Hottest months (around 30°C, humid). Jazz Festival in July. Peak season for Gulf visitors and summer holidays.

September – October

The best balance: warm sea in September, golden October. The Biennial in odd years. 29 October is Republic Day, with fireworks over the Bosphorus.

November

Cooler (around 15°C), rain returns, prices drop. The Istanbul Marathon in early November closes the Bosphorus bridge and many roads for a morning.

December

Cool and rainy (around 11°C), cosy cafés, short days. Quiet until the busy New Year week.

Ramadan, Eid and public holidays

Ramadan (about 8 February – 8 March 2027)

Life goes on almost as normal: museums, shops, transport and most restaurants in the centre stay open during the day. The magic is after sunset, when families gather for iftar — Sultanahmet Square and Eyüp fill with stalls and lights, and the mosques are lit with mahya messages strung between the minarets. Restaurants are packed right at iftar time, so book a table.

Eid al-Fitr (9–11 March 2027) and Eid al-Adha (16–19 May 2027)

Many Istanbul residents leave the city, but visitors from Türkiye and abroad arrive, so attractions are busy and apartments book up early. The Grand Bazaar and Spice Bazaar close on the first days of the holiday. The eve of each Eid is a half day.

Other public holidays

1 January, 23 April, 1 May, 19 May, 15 July, 30 August and 29 October (Republic Day). Museums usually stay open; some offices and banks close.

How to plan your dates

For April–May, September–October, New Year and Eid holidays, book 2–3 months ahead; the best apartments go first.
The best value is November and January–March (outside New Year and Eid): the same city at a much lower price.
Want to swim? Come between late June and mid-September.
Avoid long walks in the old city at midday in July and August; start early and rest in the afternoon.
Ramadan and Eid dates follow the lunar calendar and move about 11 days earlier every year — check the official calendar for your year.
