This page is for swimmers who want the deeper historical story at Captiva Island Beach: recent readings, spike frequency, and how often the beach has slipped into poor territory.

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.
