Which beaches have the lowest bacteria readings in Florida Keys?
This page surfaces the lowest posted bacteria readings in Florida Keys so you can compare same-sample numbers directly instead of relying on badges alone.
How this page sorts
Sorted by the lowest current CFU/100mL reading first, then by current status, recent poor-sample rate, and sample freshness. Only direct name-and-location samples can appear in the ranked picks; nearby-station records are listed separately.
When to use it
Use this page when you want to compare the actual current reading values side by side and not just a status label.
What still overrides it
Heavy rain, runoff, brown water, or a stale sample can make any ranked list less trustworthy for a same-day swim call.

How To Use This View
Use this page when you want to compare the actual current reading values side by side and not just a status label.
Top picks and the ranked list use only the 3 direct name-and-location beach samples. The 1 nearby-station context record stays separate and cannot identify the strongest exact beach.
If it has rained recently, use the rain guide before trusting any beach list too much.
