In short
- Istanbul in December is cool and damp rather than cold: typical highs around 11°C and lows around 5°C, with rain in most weeks and snow uncommon.
- The days are the shortest of the year, about nine hours of daylight, with sunrise after 8 am and sunset at about 5.40 pm, so sightseeing belongs to the morning and early afternoon.
- December is a good time to visit Istanbul for museums, hammams, bazaars and food, with the quietest monuments in the first half of the month and the New Year crowds in the last week.
- Christmas is not a public holiday in Türkiye, so everything opens as normal on 25 December, while churches hold services and the hotels and shopping streets are dressed for New Year.
Istanbul in December is quieter, greyer and more intimate than at any other time of year. The days are short and often wet, but the queues at Hagia Sophia shrink, the hammams feel exactly right and the city's restaurants are full of residents rather than tour groups. With the light planned well, a December trip can be one of the most satisfying ways to see Istanbul.
Our guide to Istanbul in winter covers the whole season from December to February. This one is about December alone: the weather and the light, what to do, Christmas, children, what to wear, the Bosphorus, and a day-by-day four-day plan.
What is the weather like in Istanbul in December?
Istanbul in December is cool and damp rather than cold, with typical highs around 11°C and lows around 5°C, the same figures we use across this Journal. Rain falls in most weeks, often light, and the wind matters more than the thermometer: a calm, bright day in Sultanahmet feels pleasant, while a ferry deck in a northerly wind feels much colder.
| Istanbul in December | |
|---|---|
| Typical high / low | 11°C / 5°C |
| Rain | Frequent; most weeks have wet days |
| Snow | Possible but uncommon; more likely in January and February |
| Daylight | About 9 hours; sunrise after 8 am, sunset about 5.40 pm |
| Public holidays | None in December; 1 January is New Year's Day |
| Crowds | Low for most of the month; busy in the last week |
The earliest sunsets, at about 5.35 pm, come in the first half of December, and the latest sunrises, after 8.20 am, around the turn of the year. The closing days mentioned below were checked on 4 November 2026; the official sites have the final word.
Is December a good time to visit Istanbul?
December is a good time to visit Istanbul for travellers who come for history, food and atmosphere rather than for sun. The first half of the month is the quietest at the great monuments, and hotel rates are lower than in spring or summer. The last week changes character: visitors arrive for New Year, and hotels, Bosphorus restaurants and boats fill up and charge accordingly.
The trade-off is the light. With sunset before 6 pm, a day of sightseeing is effectively eight hours long, and rain can make long walks unpleasant. Plan two or three main things a day, keep a car on call and save the evenings for dinner.
What to do in Istanbul in December
In December, Istanbul's best plans are indoors, close together and in the morning. Most of the city's great sights are under a roof, and a car between them keeps you dry.
- The great monuments, early. Hagia Sophia, the Basilica Cistern and the interiors of Topkapı Palace are calm in the first hour. Topkapı is closed on Tuesdays and Dolmabahçe on Mondays.
- The covered bazaars. The Grand Bazaar, closed on Sundays, and the Spice Bazaar are warm, dry and lively on a wet afternoon.
- A historic hammam. December is the month for it: an hour of heat, steam and a scrub on warm marble. Our Turkish bath guide explains what to expect.
- Museums. The city's archaeology, art and palace museums make whole rainy mornings.
- Food. December brings the winter fish season, hot soups, salep with cinnamon and roasted chestnuts on the street corners.
Is Christmas celebrated in Istanbul in December?
Christmas is not a public holiday in Türkiye, so museums, shops, banks and offices in Istanbul work as normal on 24 and 25 December. The city's churches do hold Christmas services, among them the Catholic church of St Anthony of Padua on İstiklal Avenue, with Masses in several languages; check service times with the church in advance.
The decorations you see in December, the lights in Beyoğlu and Nişantaşı, the trees in hotel lobbies and the shop windows, are mostly for New Year, which is the big winter celebration in Türkiye. For visitors who want a Christmas dinner, some hotel restaurants serve one on 24 or 25 December; book ahead. For a classic European Christmas, the Vienna Christmas markets are about three hours away by air.
Istanbul in December with kids
Istanbul in December works well with children if the days are short and mostly indoors. The Rahmi M. Koç Museum on the Golden Horn, full of trains, boats, cars and aircraft, can fill a morning. The Basilica Cistern, with its dim light and fish in the water, feels like an adventure, and a short ferry ride with simit to share with the seagulls is a favourite at any age.
Keep outdoor time for the warmest hours around midday, bring a change of socks, and plan a long lunch and a rest in the afternoon. Our guide to Istanbul with kids has more ideas for all seasons.
What to wear in Istanbul in December
For Istanbul in December, dress for cool rain rather than deep cold. A warm, waterproof coat with a hood, layers underneath, and waterproof shoes with good grip for wet marble and the steep streets of Galata and Balat are the essentials. Add a scarf, which also covers the head in mosques, gloves for the ferry and warm socks, as shoes come off at mosque doors. Our guide to what to wear in Istanbul covers modest dress for mosques and every season.
The Bosphorus in December
The Bosphorus in December is grey-blue and quiet, and the ferries run all year. A cruise is still worth doing, but choose the hour and the boat with care: go around midday on a clear day, when it is warmest, and choose a boat with an enclosed, heated saloon. The wind off the Black Sea is cold on deck.
The most beautiful December evening on the water is a dinner cruise: board at about 5 pm, watch the last light over the European shore, then dine as the palaces and bridges are lit. Our Bosphorus evenings are arranged on boats with heated saloons and cars waiting at the quay.
A four-day Istanbul in December itinerary
This plan is built around December's short light: monuments in the morning, indoor afternoons, and evenings by the water or at the table. Check the closing days against your dates and swap days if needed.
Day 1: arrival and the Bosphorus by night
Arrive, settle in and rest. As the light goes at about 5.30 pm, board a heated boat for dinner on the Bosphorus, or take a table by the water.
Day 2: the old city
Hagia Sophia at opening time, then the Basilica Cistern. Topkapı Palace before lunch (not on a Tuesday), with time in the Harem and the treasury. In the afternoon, the Grand Bazaar (not on a Sunday), finishing before dark.
Day 3: hammam, Beyoğlu and the festive streets
A slow morning in a historic hammam. After lunch, walk İstiklal Avenue and the side streets of Beyoğlu as the lights come on, with a stop at St Anthony of Padua. In the evening, dinner in Nişantaşı or Karaköy.
Day 4: Dolmabahçe and the Asian side
Dolmabahçe Palace in the morning (not on a Monday). Cross by ferry to Üsküdar or Kadıköy for lunch and the market streets, then watch the early sunset over the old city from the Asian shore before returning across the water.
This is the rhythm of our three-day Istanbul, privately, stretched to four, with a car by the hour waiting at every door when it rains. Our stays team can choose a room with a view of the water, which in December is worth as much as the weather.
Istanbul in December and January: New Year and after
The end of December belongs to New Year's Eve, the city's biggest night of the winter, with fireworks over the Bosphorus and tables booked weeks ahead. Our New Year's Eve in Istanbul guide covers the fireworks, boats, dinners and getting home.
After 1 January, Istanbul goes quiet again. January is a little colder than December, with highs of about 9°C and lows of about 3°C, the best chance of snow and the lowest hotel rates of the year. For a trip spanning both months, come before Christmas for the calm, or after the first days of January for the quiet; the week around New Year is for those who come to celebrate.
Checked by the Megis team on 4 November 2026. Opening hours, rules and seasons change; we confirm every detail again when we plan your trip.
