Is it appropriate to travel to Dalian on April 22nd?

In April, the temperature is about 10 degrees. It may reach 16 degrees if the weather is better. Just wear a jacket and a T-shirt.

It's spring.

There are many interesting places, but it's still a little cold to take off your shoes at the seaside. In addition, the sand in Dalian is hard and not suitable for walking barefoot.
