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.
Today's reading is in advisory territory. That does not close the beach: the sand and the walk are unaffected, but swimming is a bad idea, especially with cuts, scrapes, or a weaker immune system. The posted signs at the beach itself are the official word.
ShoreScore folds this reading into Key West (Smathers)'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.
