How To Use This Page

This page is built for the day when a beach looks tempting but recent rain makes the normal badge harder to trust. The displayed readings belong to PEPPER PARK, about 1.5 miles away, and were not collected at Avalon State Park Beach.

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.
