It’s the dirt, you need to backwash it after a storm. The leaves that get in also leach into the pool making the ph all off. So you need to backwash, shock and make sure the ph is good with either adding acid or baking soda.

I think it’s because the rain and environment is dirty, Same thing happens to my outdoor fish ponds.

The rain adds nutrients to the water and the lightning frees up nitrogen which feeds the algae.
