This page helps you make a better beach decision, not just read a badge. If it has rained heavily since Tuesday, September 8, 2026, lean conservative because rain and runoff can add risk beyond the caution already shown by this sample.

Start with the sample date

The number on this page is only as fresh as the last sample. If the date feels old for your trip, be more skeptical.

Use history as a tie-breaker

Two beaches can both look good today, but the one with fewer past spikes is usually the safer bet on an uncertain weather day.

Rain beats the badge

Stormwater runoff can change conditions faster than Florida's routine testing schedule, especially near inlets, canals, and urban drains.

If it rained recently, treat this page as stale faster

Florida DOH testing is routine, not continuous. Heavy rain can push bacteria higher through runoff before the next posted sample catches it. For Anne's Beach, wait at least 72 hours after heavy rain and be extra careful around inlets, canals, storm drains, or brown water. Read the rain guide.
