How to dress for a trip to Seattle in April?

If it is sunny, only wear long-sleeved shirts at noon (thick cotton long-sleeved shirts ... the quantity is difficult to describe) and add a suit jacket/hoodie/jacket outside. Don't wear that thin windbreaker Seattle is not like Chicago, and I don't think the wind is very strong. It is highly recommended to bring some wet fabrics and hats, because it rains in Seattle, but I only take an umbrella once a year, and it always rains in Mao Mao. It's too wet to wear a hat. It's too much to make a mountain out of a molehill. Basically, there are not many umbrellas all over the street. Seattle is near the sea. Take Beijing as an example. If the weather forecast says that both Beijing and Seattle are 8 degrees, I feel that the temperature in Seattle is a little higher than that in Beijing.

I hope I can help you. Thank you.
