Do not change lenses, batteries, or memory cards under water.
Btw, if you are changing lenses in very humid conditions with a weatherproof body, humidity can build up in the camera and really cannot escape. It is not a bad idea to put the body without the lens in an air tight container with desiccant for a while. Or move to Colorado...
As a rule, I bring one camera body per lens during tough weather conditions. When I return home, all gear goes straight into the dry cabinet. I even consider buying a separate cabinet where I keep a lower humidity for drying up humid equipment.
