The primary reason is that worms simply need to breathe. They don’t have lungs, but instead absorb oxygen through their skin. When the soil becomes saturated, the rain helps regulate its temperature, making it easier for worms to emerge.

Once on the surface, the wet conditions allow them to move around freely, aiding in their search for food and mates.
