Which beaches are the cleanest in Collier County?
This view ranks beaches in Collier County by their long-term water-quality record first, which makes it useful when you want the cleanest-looking historical profile before narrowing into a same-day choice.
How this page sorts
Sorted by lowest 12-month poor-sample rate first, then by current status, sample freshness, and current bacteria reading.
When to use it
Use this page when you care most about historical water-quality consistency, not just what looked best in one recent sample.
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 care most about historical water-quality consistency, not just what looked best in one recent sample.
The current sample still matters more than the label alone. When conditions are marginal or weather is changing quickly, open the individual beach page to compare sample date, current reading, and nearby alternatives before you go.
If it has rained recently, use the rain guide before trusting any beach list too much.
