Weather in Shanghai in December

December in Shanghai is cool outdoor weather: usable if you dress for it, not a beach brief.

In China, this is how Shanghai actually wears December, not how a country centroid would. Compared with August and January, December sits in the middle of Shanghai's year.

Pack for Shanghai in December, not for a brochure that was photographed in another season.

What to expect

Daytime

Cool days in Shanghai: a jumper you can take off, a shell in the bag. Walking is fine. Lingering outside without a layer is optimism.

Mornings and evenings are colder than the postcard. Pack for both, especially if you leave the built-up centre.

Rain

December is on the drier side of the year in Shanghai. Showers are possible. They do not define the month.

A shell that lives in the bag is enough. This is not June, and it should not be packed as if it were.

Evening

Evenings are cooler. A layer helps after sunset.

What to pack

  • A layer for cooler evenings
