This Weekend's Beach Grades for Los Angeles County

A look at beach water quality grades in Los Angeles County for the weekend of July 6-7.

The interactive map is a water quality report for beaches in dry weather from the past 30 days compiled from data courtesy of Heal the Bay, a nonprofit environmental group.

Beach grades are based on an A+ to F scale. Grades indicate the likelihood of swimmers becoming ill. Water samples are analyzed for bacteria – enterococcus, total and fecal coliforms. The report does not measure the amount of trash or toxins found at local beaches. 

The ratings on this interactive map are marked as follows:

  • Dark Blue Marker = A+ 
  • Light Blue Marker = A 
  • Green Marker = B 
  • Yellow Marker = C 
  • Pink = D 
  • Red Marker = F 
  • Purple Marker = No sample taken
