Typical water visibility
Summer visibility around Hatteras is commonly reported in the 15–50 ft range — a community-guidance estimate, not a measurement. Rain, river discharge, swell mixing, and seasonality can shift real conditions dramatically day to day.
That's exactly why Submarius exists. The in-app clarity forecast blends satellite turbidity (NOAA CoastWatch Kd490), river-plume detection (USGS), wave-mixing physics, and community post-dive reports to estimate how far you'll actually see tomorrow — with explicit uncertainty bounds, not a seasonal average.
