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.
