1 1 month 1 1 day will it be very cold to travel to Dalian? Can we go to the seaside? Are the trees and grass still green? thank you

The temperature is about 10-20 degrees, which will be a little cold, but you can still go to the seaside. Remember to do a good job of sun protection at the seaside, but you can't wash seaweed. The water temperature is too low, but the leaves are green. Dalian 10 ends and 1 starts, so it's all gone. I remember last year.
