Every year, nonprofit environmental organization Heal the Bay assigns A-to-F letter grades to beaches along the California coast.
The grades are based on bacteria pollution found in the waters.
In 2019, 92 percent of 500 California beaches earned an A or B grade during the summer season.
According to the scientists that analyze the water samples, last year had lower than average rainfall, which led to an improvement in wet weather water quality grades.
As a result, less rain means fewer pollutants and higher grades.
The winter season also revealed better results compared to 2018 due to the fact that reduced rainfall resulted in fewer negative effects caused by runoff.
The Honor Roll
The 2019/2020 Beach Report Card's Honor Roll features 20 beaches in Orange County, 11 in San Diego, three in Monterey and Los Angeles, two in San Luis Obispo, and single representatives from Del Norte, San Mateo, Santa Barbara, and Ventura.
Eighteen of the 42 Honor Roll members are open beaches, i.e., sand zones with no obstructions between the beach itself and open water.
Because they experience more wave action and greater water circulation compared to enclosed beaches, they do not have storm drains, streams, or rivers flowing into them.
As a result, open beaches tend to have better water quality.

And there's good news for Cowell Beach.
For the first time in ten years, the iconic Santa Cruz beach is not included on Heal the Bay's Beach Bummer list.
This water quality improvement comes from combined efforts by the City of Santa Cruz staff, Save The Waves and the Cowell's Working Group.
The work revealed and addressed the issue of birds roosting on or near the Wharf as a major source of past water quality issues.
The Beach Bummers' List
The list of no-go beaches with the poorest summer dry grade - F - features ten stretches of sand.
1. Fitzgerald Marine Reserve, San Vicente Creek | San Mateo County
2. Poche Beach, Creek Outlet | Orange County

Five of this year's Beach Bummers were enclosed beaches, and another five were impacted by runoff through a storm drain, river, or stream.
Heal the Bay started publishing the Beach Report Card in 1991, which featured 50 monitored locations in Los Angeles County.
Today, the organization's grading format is based on fecal bacteria pollution concentrations found in the wave-wash.
