The short answer is late September. The long answer depends on where you are marrying and how many people you are bringing.
May and June
Long evenings and hills that are still green, with a sea that is pleasant rather than warm. The light in June is the best of the year for photography. A long, soft golden hour that starts early and lasts.
Venues are not yet running at capacity, which means more availability and more attention.
The one caution: sea temperature in May is genuinely cool on the Aegean. If your guests are picturing swimming, tell them.
July and August
Reliably hot. An afternoon ceremony outdoors is uncomfortable for guests in suits, and we will talk you out of one.
An evening reception in August, on the other hand, works beautifully. The heat drops after eight and nobody wants to go inside. If your date is fixed in high summer, plan the whole day around the evening rather than fighting the middle of it.
Bodrum is the exception worth knowing: the meltemi wind makes the Aegean noticeably more bearable than the Mediterranean coast in July.
Cappadocia is hot and dusty on the valley floor, though mornings stay pleasant.
September
Summer temperatures with softer light and thinner crowds. The sea is at its warmest of the year, which surprises people. It has been heating since May.
This is the month we book most, and the last week is the best part of it. See the flight arithmetic below.
October
Still works everywhere on the coast in the first half. In Cappadocia it is arguably the best month of the year: clear mornings, low wind, comfortable afternoons and the valley colours turned. Sofia and Nikolai married on the fourth of October and it was flawless.
By the last week, evenings on the Mediterranean coast get genuinely cool. Outdoor dinners need heaters and a plan.
November to March
Not impossible, and mostly not on the coast.
İstanbul works properly in winter. Yalı interiors, palace halls, glass-covered rooftops, a city that is beautiful and empty. Cappadocia works too, and snow on the fairy chimneys is a rarer photograph than a beach at sunset.
The coastal resorts largely close. That is not a partial closure; many of them shut entirely from November.
April
The shoulder that couples underestimate. Antalya is warm enough by mid-month, Cappadocia is at its greenest, and prices everywhere are low.
The risk is rain, which is real in April and diminishes sharply through May.
The flight arithmetic, which has nothing to do with weather
Flight prices tell a different story from the thermometer.
The first two weeks of September remain school-holiday priced across much of northern Europe. The last week drops sharply. If a third of your guest list is bringing children, that fortnight is worth planning around, and it happens to sit inside the best weather window of the year.
The same effect works at the start of the season: late April and early May are cheap and warm enough on the Mediterranean coast. The airport and fare comparison.
Rain, honestly
Rainfall on the Turkish Mediterranean coast between May and September is low, and on any individual day in June or September it is unlikely.
Unlikely is not zero, which is why every venue we work with has a covered alternative written into your run sheet with a decision time attached. The full wet-weather answer.
The recommendation
Late September for a coastal wedding with a guest list. Warm sea, soft light, thinner crowds, cheaper flights.
Early October for Cappadocia.
June if photography is the priority and budget is not the constraint.
January for İstanbul, if you want something almost nobody else has.
Weather, risk and region
What happens if it rains and choosing the region. The two decisions interact more than you would expect.
