Things to do in Istanbul

  • Bosporus Strait Narrow strait in northwestern Turkey
  • Sultanahmet Mosque The defining image of Istanbul, dominating the skyline with its great dome and six minarets.
  • Topkapı Palace The imperial enclave of the Ottoman emperors for four centuries.
  • Basilica Cistern Vast underground cistern built by Justinian in 532 to store the city's water, the largest and best-known of the hundreds constructed.
  • Dolmabahce Palace This lavish palace with 285 rooms and 43 halls was the admin centre for the Ottoman Empire in its last 60 years.
  • St George's Cathedral This is modest from the outside, as the Ottomans would not permit non-Muslim religious buildings to rival the mosques.
  • Süleymaniye Mosque On top of a hill overlooking the Golden Horn, this is a magnificent mosque built by Sinan in the 1550s.

Rain days are the days with at least 1 mm of rain, as a weather station counts them.

Weather read at Sultanahmet Square, the old city, 36 km from the airport (IST): ten years of ERA5 and ERA5-Land reanalysis, through Open-Meteo's open data.

A busy month is a crowded one, not a bad one — usually it is crowded because the weather is good. It is flagged rather than scored down, and crowds alone never make a month “avoid”: that is reserved for weather worth skipping.

How busy it gets

Busiest in November; quietest in January.

Then and now

Istanbul's November days now average 16.4°C, 3.5°C warmer than in 1981–1990. 11 of 12 months are clearly warmer.

Busy and quiet times in Istanbul

Istanbul's climate is mild in winter compared to many places, making it a year-round destination. However, precipitation can increase outside the summer months.

Busiest
mid Jun to mid Sep — This period is the warmest with the most sunshine, appealing to tourists seeking summer experiences.
Quieter, still good
early Apr to mid Jun — Milder temperatures and fewer tourists make this a nice time to visit.
mid Sep to late Oct — Temperate weather with decreasing crowds after summer high season.
early Nov to late Nov — The weather is still relatively mild and the crowds are fewer.
early Feb to late Mar — Cooler temperatures and fewer tourists provide better value.

Written by a language model from the climate figures above. The month-by-month table is measured — ten years of ERA5 readings and published holiday calendars — and where the two disagree, the table is the one to believe.

What Istanbul is like

Istanbul (Turkish: İstanbul) is a very large city of fantastic history, culture and beauty. Called Byzantium in ancient times, the city's name was changed to Constantinople in 324 CE when it was rebuilt by the first Christian Roman Emperor, Constantine. More on Wikivoyage

Worth seeing
The Turkish government offers a museum pass for Istanbul's many sights and museums, and key spots on Sultanahmet, for €105 as of April 2025. The pass can be bought at the entrance of many museums or online. More on Wikivoyage
Worth doing
Hamam – Sultanahmet has many historical hamams. Some are very extravagant and cater mainly to tourists. More on Wikivoyage
Getting in
From 2020, most EU, UK, CIS and South American visitors do not need a visa. Those from many other countries including Australia, Canada and US can get an e-visa online, valid for 90 days. More on Wikivoyage
Staying safe
In Istanbul, most drivers won't abide any rules. Even if you have priority on a road junction, crosswalk, or even during green light, always be aware of your surroundings. More on Wikivoyage
Staying healthy
Tap water may not be safe depending on where you drink it. Although the tap water itself is clean, many local water tanks are not maintained properly, and one should try to avoid tap water if possible. More on Wikivoyage

Getting there

By rail from the airport (IST), by metro: M11.

Lines that stop at the airport's terminals, as mapped by OpenStreetMap contributors (ODbL); the operators' own timetables have the times and fares.

How far Istanbul is depends on where you set off from — the months above do not.

Like a local in Istanbul

On arrival

  • Paying — Cards are widely accepted in cities, often with a PIN; carry lira for dolmuş minibuses, street food, markets, small shops and tips.
  • UPI, for visitors from India — Not accepted for paying here; bring a card that works abroad.
  • Tipping — About 5-10% in restaurants, left in cash because tips cannot go on a card; let taxi drivers keep the change.

Getting around Istanbul

Istanbulkart on the metro, trams, buses, Marmaray and ferries; buy and top up at station machines or kiosks. One card can pay for several people.

  • Apps — Rides: BiTaksi, Uber. Maps: Google Maps, Apple Maps. Messages: WhatsApp. Uber and BiTaksi book licensed taxis.

İETT (or just toplu taşıma) is the municipality's public transportation company. Istanbul's public transit system can be difficult to figure out. More on Wikivoyage
