1. Due to osmosis, or the diffusion of water particles, the water in the bodies cells are more likely to be released through your skin cells' permeable membrane. Hence perspiration is more likely to overcome the body.
2. During humid weather conditions, the body is, on low accounts, overheating from the inside. Hence perspiration is more likely to overcome the body.

I think that its more of what the temperature does to YOU. The temperature won't really change the soccer ball's performance if your comparing humid to dry. Its slightly possible that if the airs humid, it might be heavy which could lessen the curve, but i doubt that. Its more of what the temperature does to you. If its dry, you'll need some water (duh! lol) which will help you in performance. If its humid, you will need water again, but you might feel sluggish or a bit of difficulty moving or kicking. All in all, its better in dry conditions, but not by much. Hope that helps
