How is the weather in Beijing recently? How to dress for a trip?

Children want some autumn clothes and trousers, plus a coat, and so do adults. The changes in these days can be imagined. Every Saturday and Sunday, I am tired of eating sandstorms when it is windy and rainy. You can't go out to play during the break. I'm still depressed. I'd better bring the children back later this month! That will make the weather better!
