Typical water visibility
Summer visibility around La Jolla Shores is commonly reported in the 10–30 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 starts from this coast's typical clarity for the time of year, built from in water measurements and satellite ocean color, then subtracts wave stirring, river and runoff plumes, and tide movement to estimate how far you'll actually see, shown as a low to high range, not a seasonal average.
