Pacific Ocean: toxic algae advisories
Pacific Ocean, San Diego County. See all San Diego County waters.
What the state's records say
The state recorded an end date of Dec 30, 2022.
Last advisory on file: Dec 2, 2022.
That reflects what the state knew on that date. It is not a finding that the water is safe now: blooms can return within days, and many are never reported.
Before you go, check the state's official algae page and any signs posted at the water.
Dogs at Pacific Ocean
The state recorded an end date of Dec 30, 2022. For Pacific Ocean, that is not the same as an all-clear for today. Look at the water before your dog goes in: keep it out of green, blue-green or scummy water and away from mats on the shore.
