Visibility you stop trying to measure. Bumphead parrotfish, manta corridors, a soft-coral wall called the Wall of Wonder.
Swaraj Dweep has the clearest water and the most developed dive infrastructure in the Andamans — reefs that start shallow enough for a first open-water dive, and walls that keep going for people with a logbook.
Visibility is at its best between December and April. These reefs have taken bleaching events over the past decade, and the operators worth diving with will tell you about it before you ask.

The conventional advice is one night. The right answer is three — long enough that you stop checking your phone, short enough that you're still in love with the boat.
