Yes! Exactly!
More seriously it's physics. The materials that you are wearing (actually synthetics are usually worse) build up a static charge on them due to friction, particularly when you drag them over your body taking them off. This discharges through your body or whatever bit of metal is nearby.
The static buildup is worse in the dry because dry air (and bodies) conduct less well than damp or wet air/bodies.
You could go camping in the rain...
