1What's the weather like in Shanghai since October 7th? Help me.

There was a precipitation process in the middle of ten days (around the 5th) due to the eastward movement of the upper trough. In addition, another high-altitude trough moved eastward in the late period, affecting our city and increasing the cloud system. It is estimated that the ten-day rainy weather will last for 2-3 days, with rainfall of about 20mm, average temperature of 24-25℃ and extreme minimum temperature of 19℃.

I suggest you take rain gear and long sleeves. You can buy it in Shanghai.
