The weather is so good that I want to go out to play.

It has been raining for many days, and now the sun is out.

The long-lost sun has finally come out, which means that it has been raining for many days, or it is cloudy or snowy, and there is no sun. Occasionally, when the sun comes out, people will be in a good mood, and almost everyone doesn't like it. They will be very energetic when they go out to play on rainy days and sunny days, even if they work in the unit.
