What was the temperature and weather like in February last year in Beijing?

It's warmer overall this year, and so is Beijing. Beijing is very cold every year now, but it is warmer than the previous two years. You don't have to wear too many clothes when you come to Beijing. It's 8- 10 degrees during the day these days.

So you can wear a sweater. You can wear a thin cotton-padded jacket outside. If you wear thermal underwear and pants inside, you can wear a down jacket outside. You don't have to wear too much.
