The short answer: late April to early June, and mid-September to the end of October. Those are the weeks when the valley is comfortable to walk, the light is kind to photographs, and the ruins are busy but not overrun. Everything else is a trade-off between heat, rain and crowds — and all of it is manageable if you pick your hour.
Spring: April to early June
The best season by a clear margin. Temperatures sit in the pleasant high teens and twenties Celsius, the hills around Selcuk are green, poppies come up between the stones, and the storks return to nest on the aqueduct in town and on the lone column of the Temple of Artemis. Easter and the early cruise season bring crowds, but the walking is a pleasure rather than an endurance test. Bring a light layer for the mornings.
Summer: late June to early September
Hot, dry and bright — regularly 33 to 38°C in July and August, with the marble reflecting the heat back at you and almost nowhere to hide from the sun between the upper gate and the library. It is entirely doable, and thousands do it every day, but only with an early start: be at the gate when it opens, be finished by noon, and treat the middle of the day as somebody else's problem. Hat, sunscreen and more water than you think you need are not optional.

Autumn: mid-September to October
Spring's equal, and often better for light. The fierce heat breaks, the sea stays warm for anyone combining ruins with a beach, the harvest is in around Sirince, and the photography in the low golden afternoons is the best of the year. Late October begins to see the first rain and the cruise ships thin out — for many of our guests this is the sweet spot of the whole calendar.
Winter: November to March
Underrated, if you accept the risk of rain. Days are mild rather than cold — often 10 to 15°C — and Ephesus in winter can be close to empty, which is an extraordinary way to see it: the Library of Celsus with nobody in front of it is a memory that lasts. The trade-offs are shorter opening hours, wet marble that turns slippery, some closed restaurants in the villages, and the chance of a washed-out day. Pack a waterproof and shoes with grip.
The hour matters more than the month
Crowds at Ephesus are not spread evenly through the day; they arrive in a wave. The cruise ships dock in the morning and their coaches reach the gates between roughly 10:00 and 13:00, along with the Izmir day trips. Arrive at opening and you get an hour or two of near-solitude on the same marble; come after about 15:00 and the site empties out again while the light improves. The middle of the day is both the hottest and the most crowded — the one window worth avoiding whatever the season.
Special dates worth knowing
Every year on 15 August the Feast of the Assumption is celebrated at the House of Virgin Mary, with services and pilgrims from around the world — extraordinary to witness, very busy, and worth planning around either way. Turkish public holidays and the two religious holidays (Ramazan Bayramı and Kurban Bayramı, which move each year) fill the sites with domestic visitors. Tell us your dates when you enquire and we will tell you honestly what to expect.
