Most people pack for Istanbul like it's a Mediterranean beach city. It isn't. Winters are wet and chilly, summers hit 31°C (88°F), and in any season you'll climb steep hills and take your shoes off at mosques, so footwear and one cover-up layer matter more than outfits.

Season by season
Winter
December–FebruaryHighs sit at 10°C (50°F) to 12°C (54°F) with lows of 4°C (39°F) to 7°C (45°F), and December is the wettest month with 14 rain days. The wind off the Bosphorus makes it feel colder than the number, especially on the ferry to Kadıköy. Bring a warm coat, a waterproof layer and shoes that grip wet stone. The upside is thinner crowds at Hagia Sophia and Topkapı.
Spring
March–MayMarch is still raw at 15°C (59°F) with 13 rain days, but by May highs reach 21°C (70°F). Layers work best here, a light sweater plus a rain shell you can stuff in a bag. April tulips in Emirgan Park and Gülhane are the reason to come now. Evenings on the water get cool, so keep a jacket with you.
Summer
June–AugustJuly peaks at 31°C (88°F) and July and August nights stay at 21°C (70°F) to 22°C (72°F), with only 3 or 4 rain days a month. Pack breathable clothes, but keep one outfit that covers shoulders and knees for the Blue Mosque and Süleymaniye. The walk up from Eminönü to the Grand Bazaar is steep in this heat, so carry water. Ferries are the coolest seats in the city.
Autumn
September–NovemberSeptember is still warm at 26°C (79°F), October drops to 21°C (70°F) and November to 17°C (63°F), with rain climbing back to 10 days by November. This is the best window for walking the city. Pack layers and a light waterproof for later in the season, because evenings in Karaköy and along the Bosphorus cool off fast.

What shoes should you pack for Istanbul?
Comfortable sneakers with real grip. The old city is all hills and worn cobbles, and getting from Karaköy up to Galata and İstiklal is a climb whichever street you take. Pick shoes you can get off and on fast, since you'll remove them at every mosque. Heels don't survive Sultanahmet.
What do people wear in Istanbul?
Istanbul dresses more like a European city than people expect. Jeans, sneakers and smart casual are normal in Beyoğlu and Nişantaşı. At mosques, women cover their hair and everyone covers shoulders and knees, and a scarf in your bag handles both.
What plugs does Istanbul use?
Turkey uses type C and F plugs at 230V, the same round two-pin plugs as most of Europe. Coming from the US or UK, you'll need an adapter. Most phone and laptop chargers handle 230V, but check anything that heats up, like a hair straightener.

What should you leave at home for Istanbul?
Leave the heels at home, along with any plan to live in shorts, because mosques need knees covered. A big suitcase is a pain on the tram and on the slopes of Cihangir and Galata, so go smaller if you can. Beach gear only earns its space if you're heading out to the Princes' Islands.
