I spent about 2.5 hours in Nohoch today. Visibility is less than 30 feet. If you get far enough off the line to see a formation, you can't see the line. It is just a white haze. The first cenote on the main line upstream where you can normally see ambient light for 100' coming up to it. I realized I was there when I saw the poop piles on the floor. There was zero ambient light coming through the haze.
We will head elsewhere tomorrow. I was really disappointed as I love Nohoch. A lazy swim for 150minutes in a set of 80s isn't easy to get anywhere else.
To be fair...
I did tell you it's been raining and visibility would be down.
