What clothes should I pack for Istanbul in early October, with warm days, cool evenings and possible rain?

Around midday, a T-shirt can be enough on warm days, but conditions may change later in the afternoon, so bring a light sweater or jacket.

Bring a windproof jacket for evening walks, as nights are already cool. A practical combination is a T-shirt with a sweatshirt as an extra layer.

If rain is forecast, add a raincoat or lightweight waterproof jacket. A useful changeable-weather set is a T-shirt, long-sleeve top, denim jacket and a scarf or shawl for your shoulders.

In cool and especially rainy weather, a sweater, cardigan or hoodie over a base layer is usually sufficient. Rain makes it feel colder, so it is worth carrying an extra outer layer.
