What is the weather like in Hamburg, Germany?

The climate of Hamburg belongs to maritime climate. Compared with Germany, the change is mild, but it is difficult to see the sun. It is warmer than Beijing when it is cold in winter, and it is seldom higher than 30 degrees in summer. There must be sea breeze in winter, but it's not biting. Just wear jeans. I don't wear long trousers and woolen trousers (for reference only, I am a beautiful frozen person, and I will never wear long trousers within-10 degrees). Suggestion: a down jacket, personally think that the medium and long ones are more practical. Definitely jeans. Sweater, very practical, be sure to bring it. However, it is convenient and cheap to buy clothes in Germany. It depends on whether you are a boy or a girl. If a boy is tall, it is easy to buy clothes. If he is short, it is difficult to find the right size. For girls, I prefer more feminine clothes or bring them from China. I like Korean clothes, which are not available here. I can't wear ZARA all year round.
