Every day while I was in Mexico my lenses would fog up (as would my glasses of course) when exiting a building to the outside. The humidity was intense and even with a lens cloth, the fog would return instantly.
So what do you do when your lenses keep fogging up?
Keep the lens cloth handy and keep wiping as needed. It takes 5 minutes or so before the lenses will stop fogging. After that, you should be good to go.
What I wouldn’t recommend
Do not remove the lens from the camera. If you do, and there is debris in the air, it will wind up sticking to your mirror and sensor due to the fog which is acting as glue.
