What's the weather like in Copenhagen in September?

The daytime temperature is about 20-25 degrees, and at night it is about 15 degrees. It's cool in the morning and hot at noon. Now I always wear short sleeves, a coat and trousers in the morning. You don't have to wear a coat after work in the afternoon, and you don't have to go to work during the day.

I think if you are on a business trip, you can wear a shirt (short sleeves, seven minutes is fine), a suit jacket, trousers and ordinary leather shoes. If you are visiting, you can wear a small coat, T, jeans and sports shoes ~ I don't think skirts and shorts are needed, just bring one or two ~

To put it simply, you must prepare a coat when you go out. In addition, it is recommended that the coat be waterproof and there is no need to use an umbrella in light rain. Danes are like this ~ September is a rainy time ~

The above is my suggestion, but the weather is unpredictable and often changes ~ this summer is extremely hot ~
