im going to qingdao in november. what's the weather like. and also are there any night markets

It would be a little cold in Nov. when the lowest temperature shall be 2-5℃ and the highest is around 16℃. For the whole month, sunny days would be the majority, but several rainy may also happen. Prepare sweater, Long John, jackets and jeans, perhaps also rain coat. Just check ahead the weather forecast.

Yes, there are night markets in the city. I know the Taidong Yan'an 2nd Road Night Market and Sifang Liqun Night Market. I also remember there was a night mrket on Nanjing Road, but not sure if it still exists.
