When to fly to Istanbul to buy stock — and when not to
The trip that goes wrong is almost never the one with the wrong suppliers. It is the one booked in the wrong week. You land, you walk into Merter, and half the shutters are down — not because the business failed, but because it is the second day of Kurban Bayramı and everybody is at their mother’s house in Konya. Nobody tells you this, because to a Turkish supplier it is as obvious as Christmas. So here is the calendar, month by month, to the end of 2027.
The short answer
Do not book 8–12 March 2027 or 15–19 May 2027 — those are the two religious holidays, and they are fixed and already known. Treat late July to mid-August and the last two weeks of December as unreliable. The best weeks to walk into a showroom are the ones you are in right now: October and November, when the autumn/winter racks are full, and again mid-March to the end of April.
The four windows when nobody will answer you
Two of these are law. Two are habit. The difference matters, because you can look the legal ones up and plan around them years ahead, while the other two need a message to your own supplier.
1. Ramazan Bayramı — 8 to 12 March 2027
The three-day holiday that ends Ramadan. In 2027 the eve, arife, falls on Monday 8 March and is a legal half day — workplaces close at one in the afternoon. The holiday itself runs Tuesday 9 to Thursday 11 March.
Friday the 12th is, on paper, a normal working day. In practice the Turkish government has repeatedly extended these holidays by decree to bridge to the weekend, and in years when it does not, a good number of people take the day anyway. No decree exists for 2027 yet, and none will until a few weeks before — that is simply how it is decided. Plan as though the whole of 8–12 March is gone, and treat any extra days as a bonus you never counted on.
2. Kurban Bayramı — 15 to 19 May 2027
The bigger of the two, four days rather than three, and the one that empties Istanbul. The arife is Saturday 15 May, and the holiday runs Sunday 16 to Wednesday 19 May.
2027 is, by accident, a gentle year for this one. The eve and the first day both fall at the weekend, and the last day collides with a national holiday that already existed.
Here is what that means in working days. Turks lose less time than usual, because 19 May is also 19 Mayıs Atatürk’ü Anma, Gençlik ve Spor Bayramı — one of those years where two holidays sit on the same square of the calendar and the country quietly loses a day off. For you, the working days that disappear are Monday 17, Tuesday 18 and Wednesday 19 May. Thursday the 20th is technically back to work; realistically it is the day people travel home. I would not book a first meeting before Friday 21 May.
3. The factory summer break — late July into August
This one I have to be straight with you about. Every buyer’s guide says Turkish garment production takes its annual leave from roughly the last week of July to the middle of August, and that matches what I see. But it is not a law and it is not published anywhere. There is no government decree and no trade-body calendar setting those dates. It is a custom, and customs vary by firm.
So the honest advice is the boring one: if you want to travel in that window, write to your three most important suppliers and ask them directly when they close. That is a one-line message and it settles the question for your trip specifically, which is worth more than any general rule I could give you.
4. The last two weeks of December
Turkey has no Christmas holiday — 25 December is an ordinary working day. What it has is year-end. Accounts close, stock is counted, and a small new customer asking about a sample is the least interesting thing in anybody’s inbox. 1 January 2027 falls on a Friday, which makes a three-day weekend at the front of the year.
Again: this one is habit rather than law, reported consistently by people who buy here rather than documented anywhere official. Take it as a reason to be sceptical of that window, not as a closed door.
The calendar, October 2026 to October 2027
Thirteen months in one picture. I have coloured it the way I would decide: black for the stretches I would fly in, red for the ones I would not book at all.
And the official dates underneath it. Everything in this table is either a statutory public holiday or a Diyanet calendar date, cross-checked against more than one Turkish source.
| Date | What it is |
|---|---|
| Wed · 28 Oct 2026 | Half day from 13:00 — eve of Cumhuriyet Bayramı |
| Thu · 29 Oct 2026 | Cumhuriyet Bayramı, Republic Day |
| Fri · 1 Jan 2027 | New Year |
| Mon · 8 Feb 2027 | Ramadan begins (not a holiday) |
| Mon · 8 Mar 2027 | Half day — arife of Ramazan Bayramı |
| Tue–Thu · 9–11 Mar 2027 | Ramazan Bayramı |
| Fri · 23 Apr 2027 | Ulusal Egemenlik ve Çocuk Bayramı |
| Sat · 1 May 2027 | Emek ve Dayanışma Günü |
| Sat · 15 May 2027 | Half day — arife of Kurban Bayramı |
| Sun–Wed · 16–19 May 2027 | Kurban Bayramı; 19 May doubles as Atatürk’ü Anma, Gençlik ve Spor Bayramı |
| Thu · 15 Jul 2027 | Demokrasi ve Millî Birlik Günü |
| Mon · 30 Aug 2027 | Zafer Bayramı, Victory Day |
| Fri · 29 Oct 2027 | Cumhuriyet Bayramı |
One caution on the two bayram dates. They come from Diyanet’s published astronomical calendar, so they are known years ahead and they are not going to move — but the Turkish press gets them wrong often enough that I found a national newspaper running the March dates a full day out while I was checking this. If you see a date that disagrees with the table above, check Diyanet rather than the headline.
Which holidays actually cost you days
A public holiday only hurts you if it lands on a day you were going to work. Read the weekday column above and the year splits neatly in two.
The cheap ones. 1 May 2027 is a Saturday — it costs a buyer nothing. 23 April is a Friday and 30 August a Monday, so each is a long weekend that removes one working day and is easy to plan around. 29 October 2027 is a Friday, same story.
The expensive ones. The two bayram weeks, obviously. And the one closest to you as you read this: 29 October 2026 is a Thursday, with Wednesday the 28th a statutory half day. A holiday on a Thursday is the classic setup for a bridge Friday, which would take out Wednesday afternoon through Sunday. Whether that bridge is declared is, again, not yet known. If you were thinking of the last week of October, move it a week either side.
15 July 2027 is also a Thursday, with the same bridge risk.
When to actually go
Avoiding the bad weeks is only half of it. There are weeks that are actively better, and they come down to three things: what is on the racks, what the weather does to a day spent walking, and how much you pay to be there.
What is on the racks
Istanbul wholesalers work to two seasons. Spring/summer ranges come out from roughly February to April, autumn/winter from August to October. Arrive at the start of a season and you are choosing from a full range with the sizes still complete; arrive at the end and you are picking through what nobody else wanted.
I will flag this one honestly too: those months are the trade’s own working rule of thumb, reported by Istanbul wholesalers themselves rather than published by any trade body. I could not find an official source for it, because there is not one — the export associations publish figures for factories, not rack dates for showrooms.
The practical version, which I am confident about: you are reading this in the good half of the autumn/winter window. October is the month I would pick out of the whole year.
What the weather does to your feet
This sounds trivial until you have done nine hours between showrooms in August. Istanbul averages 28 °C in August and 8 °C in January, and December is the wettest month of the year with more than four inches of rain.
| Month | Avg high | Rain | For a buying day |
|---|---|---|---|
| Oct | 19 °C | 80 mm | About as good as it gets |
| Nov | 15 °C | 78 mm | Fine, take a coat |
| Dec | 10 °C | 107 mm | Cold and the wettest month |
| Jan–Feb | 8–9 °C | 75–88 mm | Cheapest flights, hardest walking |
| Mar–Apr | 11–15 °C | 50–75 mm | Good, and new S/S ranges |
| May | 20 °C | 38 mm | Excellent — mind the holiday |
| Jun | 25 °C | 35 mm | Warm but workable |
| Jul–Aug | 28 °C | 24–26 mm | Hot, dry, and half the trade is away |
| Sep | 24 °C | 52 mm | Very good, A/W arriving |
Winter is the cheapest time to fly and sleep in Istanbul, and summer the most expensive. That is a real saving if your budget is tight — there is a whole post on what a first trip actually costs — but weigh it against February being the month you are walking between showrooms in the rain at nine degrees.
The week, the day, the hour
Once you have the right month, the shape of the week matters more than people expect.
- Merter trades Monday to Friday, roughly 09:00 to 19:00. Saturday runs to about two in the afternoon. Sunday is closed. Like the summer break, these are trade custom rather than regulated hours — individual showrooms vary, and the big ones stay open later than the small ones.
- Do not build a plan on Saturday. A half day gets you two or three showrooms, not ten, and the people who make decisions are often not the ones in on a Saturday.
- Give yourself three full working days minimum. Fifteen to twenty showrooms is a realistic target for three days if you are organised, and fewer than that is not enough to compare anything. A Tuesday-to-Thursday trip with travel either side is the smallest version that works.
- Turkey is UTC+3 all year. It abolished daylight saving in 2016 and never brought it back, so the gap to you changes twice a year even though Istanbul never moves. From the Baltics, Finland, Greece or Romania, Istanbul is one hour ahead in winter and on the same clock in summer. From Germany, Poland, France or Italy it is two hours ahead in winter and one in summer. Almost everybody gets this the wrong way round once. Check it before you set a call.
- Land the night before, not the morning of. A flight that gets in at eleven costs you the whole first morning, and mornings are when showroom staff have time.
Two things I am asked constantly and am not going to pretend I know. Whether Osmanbey and Laleli open on Sunday: I have seen it claimed both ways and I have not been able to confirm it, so ask the specific supplier. And the Friday midday prayer: I cannot find any evidence of a standard closure in the wholesale districts, and I am not going to invent one. What I do is avoid putting anything critical in early Friday afternoon, which costs me nothing either way.
The month before the holiday
Ramadan itself runs 8 February to 8 March 2027. It is not a holiday and nothing shuts. But the rhythm changes, and there is one specific trap in it.
The last ten days or so before bayram are when every existing customer wants their order out of the door. A supplier with three long-standing accounts shouting at him is not the supplier who is going to work out a first-time order for a new buyer he has never met. You will get shorter answers and slower ones, and it will not be because he does not want your business.
Count backwards from the holiday, not forwards from your order.
This is the part that catches people. If you place an order in the last week of February with a three-week production time, your goods are not late because someone let you down. They are sitting in a workshop that closed on 8 March and reopens on the 12th. Add the holiday to the lead time yourself, before you promise anything to anybody.
If you have to go in a dead week
Sometimes the flight is booked or the dates are not yours to choose. It is not a wasted trip, as long as you change what you expect from it.
- Walk the districts anyway. Shutters down still tells you who is where, how big they are and what is in the windows. Photograph the signage and the codes. That is a map you will use on the next trip.
- Go a few days early rather than a few days late. The days before a bayram are busy but alive. The days after are dead — people travel home, and stock has not been replenished.
- Use it to see things you never have time for. The Grand Bazaar, the retail streets, the new designer outlet by the airport — all open, all useful for calibrating what good construction and honest pricing look like.
- Send the messages, do not expect the replies. Write to the suppliers you want, say plainly that you know it is bayram and that you will call after. That single sentence reads as someone who understands how the trade works, and it puts you at the top of the pile when the shutters go up.
What I would check before booking
Five minutes, in this order.
- Check your week against the table above. If it touches 8–12 March or 15–19 May 2027, stop and move it.
- Check for a bridge decree if you are travelling near a holiday that falls on a Tuesday or a Thursday. It gets announced a few weeks ahead, in the Resmî Gazete and immediately in every Turkish paper.
- Ask two of your own suppliers when they close for summer, if you are going anywhere near August. One line, and it beats any general rule.
- Count the working days, not the calendar days. A Friday-to-Monday trip over a long weekend looks like four days and is one.
- Then book the hotel. Not before — moving a hotel is easy, moving a flight is not.
None of this is complicated. It is just the sort of thing you only learn by having lost a trip to it once, which is an expensive way to find out where the districts are when they are shut. It is also on the list of things that go wrong on a first buying trip, and it is the one that is entirely avoidable from your desk.
Common questions
When is the best time of year to buy wholesale clothing in Istanbul?
October and November, and again mid-March to the end of April. Those windows catch new season ranges while sizes are still complete, and the weather is mild enough to spend a full day walking between showrooms. September is nearly as good.
When is Ramazan Bayramı 2027 in Turkey?
The eve is Monday 8 March 2027, a legal half day, and the holiday runs Tuesday 9 to Thursday 11 March. Whether the government bridges to the weekend with a decree is decided only weeks in advance, so assume 8 to 12 March is unavailable.
When is Kurban Bayramı 2027 in Turkey?
The eve is Saturday 15 May 2027 and the holiday runs Sunday 16 to Wednesday 19 May. The fourth day coincides with 19 Mayıs Atatürk’ü Anma, Gençlik ve Spor Bayramı. For a buyer the working days lost are Monday 17 to Wednesday 19 May.
Do Istanbul wholesale markets close in August?
Much of Turkish garment production takes annual leave from roughly the last week of July to mid-August. It is a long-standing trade custom rather than a legal closure, it is not published anywhere official, and it varies from firm to firm — so confirm the dates with your own suppliers rather than relying on a general rule.
What days and hours is Merter open?
Roughly 09:00 to 19:00 Monday to Friday, with Saturday trading until about 14:00 and Sunday closed. These are trade custom rather than regulated hours, so individual showrooms vary. Opening on Sunday in Osmanbey and Laleli varies too, so ask the individual supplier.
How many days do I need in Istanbul for a buying trip?
Three full working days is the realistic minimum, which covers fifteen to twenty showrooms if you are organised. Count working days rather than calendar days, and avoid building a plan around a Saturday, which is a half day.
Is Turkey on daylight saving time?
No. Turkey has been on UTC+3 all year round since 2016, but the countries you are calling from still move their clocks, so the gap changes. From the Baltics, Finland, Greece or Romania, Istanbul is one hour ahead in winter and the same in summer. From Germany, Poland, France or Italy it is two hours ahead in winter and one hour ahead in summer.
