Beijing is really located in a poor position with mountains block and dry condition especially during the summer, only the east side opens to the Yellow Sea. So if there's no seasonal wind towards to the East, it's almost impossible to clean up the smog natually. Plus, recent dayz reflects a typical weather condition of Beijing's summer these fews years, thanks for the climate change, the record high of rainfall and humidity with the help of heatwave combined causing plenty of dust raising up over the city's skyline. That's what the locals usually called the ''Suana day''. Of course it feels like as it sounds in a Suana. But that also means there would be more upcoming rainfalls in a few days, and until the 7 th August is the start of Autumn, according to the record, Beijing would be ''cooler and fresher''.
28th July Beijing's weather meets some shower and air quality again improved dramatically. Unless the local climate gone wild, Beijing's Autumn might be more comfortable than these few days.
