Typical water visibility

Summer visibility in Montauk typically ranges from 5–25 feet, depending on recent rain, river discharge, and swell mixing. Winter and post-storm windows can drop this significantly. Submarius's water-clarity forecast blends satellite turbidity (NOAA CoastWatch Kd490), river-plume detection, wave-mixing models, and community post-dive reports to predict how far you'll actually see on a given day — not just the summer average.
