Why doesn't it rain in the peaceful elite rainforest?

Rainy days appear randomly, and cloudy days will appear randomly in the classic model-rainforest map -Sano with a small probability. In this weather, cloudy days, foggy days and rainy days will appear alternately at random.

So the new rainforest map has three kinds of weather: sunny, foggy and cloudy. Chicken friends can judge what kind of weather this game is by the current weather conditions on the island of birth when they enter the game.
