What this means for swimming
Enterococci is the indicator bacteria official beach programs test for, typically every week or two. Under 35 per 100 mL is the all-clear band; 71 and above usually triggers a swim advisory. Counts move week to week, and heavy rain can spike them for a day or two as runoff drains.
ShoreScore folds this reading into St. Augustine Beach's overall 0-100 score alongside live weather, surf, UV, seaweed reports, and storm radar, so one number tells you whether it's worth the trip.
