This page is built for the day when a beach looks tempting but recent rain makes the normal badge harder to trust. The displayed readings belong to MAIN BEACH, about 0.8 miles away, and were not collected at Fernandina Beach.
Use this view as a decision aid, not a guarantee. The latest sample, visible runoff, and recent weather still matter more than any single list or chart.
If you want the main same-day answer instead, go back to the Fernandina Beach beach page.
