i am going to nanjing. i want to expose sun every day as i am used to do for this.

The sunny and rainy days are half to half. The rainy days is about 8-12 days a month on average, and in June, July and august, there are a lot of rainfall, but there are still sunny days. I’m wondering you cannot stand the sunny days in these three month, for it is so hot that you may want to stay indoors.

how many sunny hours in a day on average?

Oh, according to the previous weather statistics, throught the whole year, the average duration of sunshine is 5 to 6 hours per day.
