The verdict
Choose Istanbul if the city itself is the trip: notable places packed within walking distance of the centre, far more museums, a much wider range of kitchens and more to occupy children.
Choose Izmir if you mean to swim: 4 beaches nearby against Istanbul's 2, sea above 21°C for more of the year, warmer days and near-dry summers.

Where they differ
Istanbul packs many times as many notable places within walking distance of the centre, about three times as many museums plus a UNESCO-listed place within day-trip reach, three times as many restaurants near the centre with a far wider spread of kitchens, and many times as many attractions for children.
Izmir is the better base for swimming, with 4 beaches nearby against Istanbul's 2 and sea warm enough for longer. It also runs warmer through the year, highs of 13-34°C against 9-30°C, and its summers are drier.
Where they are alike
Weather is where they sit closest. Both reach a sea of 24°C in August, both dry out for the summer, and neither has a winter that closes the city, with the rain falling from November to March.
Neither works as a base for wild country: protected land nearby is thin in both cases, and park space near the centre is much the same. Both are coastal cities, the sea at the edge of the centre.
Which traveller are you?
Museum-and-dinner travellers should take Istanbul. It holds about three times the museums, a UNESCO-listed place within day-trip reach, and a far wider range of kitchens, with drinking and club options roughly double Izmir's.
Anyone whose holiday is built around swimming should take Izmir: 4 beaches nearby against Istanbul's 2, sea staying above 21°C well past midsummer, and long dry warm spells.
Families are better served in Istanbul, which has many times as many attractions near the centre and a core you can walk; both cities have 2 theme parks within reach, so that is not the deciding factor.
What the numbers don't tell you
The value figure is a national price level, identical for the two by construction, so it says nothing about which is cheaper on the ground. The €100 a day beside it is one national estimate rather than a measurement of either city.
A warm month and a comfortable one are not the same. Izmir's driest, sunniest weeks come at 34°C, and the monthly picture favours spring and early autumn over midsummer. In Istanbul, the density that puts sights within walking distance belongs to a city of 15.7 million, so proximity and crowds arrive together.
When should you go?
The figures behind each month. Each row is shaded against that destination's own year, so the deepest cell is its best month for that measure and the palest its weakest. Shades are not comparable between the two rows.
Temperature and rainfall are thirty-year climate normals, averaged over the years shown. Izmir: 1991-2020 normals, Izmir (3.4 km from centre). Istanbul: 1991-2020 normals, Istanbul / Goztepe (9.9 km from centre).
Istanbul is at its best from May to September, when highs run 22-30°C and monthly rain stays under 30mm. Winter is cool and wet, above 100mm in the wettest month, and the sea is too cold for swimming.
Izmir stretches further at both ends, from April to October, and its high summer is all but rainless, 1mm in July, with August at 34°C. Spring and early autumn are its comfortable stretch; its winters are the wetter of the two.

The busiest departure cities for these two, with a place kept for each other part of the world. Busiest means arriving passengers where an official count exists, and where none does, the number of non-stop services flown: official route statistics are published by the European reporting countries and by nobody else, so a table ranked on them alone would offer a reader in New York or Tokyo ten European cities. Flying times are estimated from the distance between airports, and every row is a city flown non-stop to both. Where the typical offer connects anyway, the stops are shown. Under each figure is the airport the flight lands at and how far that is from the centre, because the nearest airport is not always the one a route is flown to. Where both columns name the same airport it is one flight, and the difference between the two is the distance printed beside it. Typical return fares for 2026-09 to 2026-10, cached market data up to 7 days old. The figure is the middle half of the offers found, so a single price means they agreed and a range means they did not; for a typical route that middle half spans about a quarter of the median, and for the least settled routes rather more than the median itself.
