This is closely related to climate control.

In higher climates, moisture in the air can cause high-quality materials (such as wood) to swell, causing cracking and splitting. As a result, the moisture accumulated on the surface of the housing leaves oxidation spots.
In low-humidity climates, certain materials may lose moisture and shrink, causing cracks and splits.
According to information from the Institute of Construction and Woodworking, this is the best humidity range in North America:
