What's the weather like in Shanghai during the National Day? Do I need to wear long sleeves?

This season, Shanghai is an era of "dressing casually", and long short sleeves, long shorts and short skirts are all suitable.

During the National Day, the highest temperature in Shanghai was between 25 and 28 degrees. If you walk outside during the day, it will be a little hot, and it will be a little cooler in the morning and evening. Young people can wear short sleeves and old people can wear long sleeves.
