Skydiving in the rain

I’m on my way to a karaoke bar. As I stopped at the end of my road, I noticed there was a person skydiving in the field across from me. There was no one behind me so I sat and watched them float to the ground. Maybe the rainy weather up a notch in challenge. It’s not particularly windy so it doesn’t seem unsafe. Just wet. Where did he come from. What plane did he jump out of just random in a field. I wonder if it was planned.
