Re: How to tell how thick the fog is...
Once your in it look for land or a vessel that is just visible and then use your radar to measure the distance.
In my experience your depth perception goes all to heck in fog. And so can your sense of direction.
Current weather conditions on Wx often describe visibility. That is actually not that current.
