Grunion Run 2023 schedule

The Grunion Run 2023 schedule for California has been released. California grunions (Leuresthes tenuis) are small bait fish that breed by swimming onto sandy beaches at certain moon and tide cycles up and down Southern California, and going on a grunion run is a great way of seeing this unique species. But first, you need to know when they run and how to find them on a run.
Where have grunion runs been happening so far in California in 2023?
Knowing the best beaches to find grunion runs on in California is obviously key to predicting where the next run will occur.
So far this year, confirmed Grunion runs have occurred in Southern California on the following beaches:
​
-
Seal Beach (LA County)
-
Cherry Beach (Long Beach, LA County)
-
Cabrillo Beach (LA County)
-
San Pedro area (LA County)
-
Coronado Ferry Landing Beach (San Diego)
-
Campo Archelon (Baha, MX)
When do grunion runs happen in California in 2023?
Grunion runs occur between March and August up and down Southern California when a combination of moon, tide and water temperature trigger the California grunion to swim right up to the beach to breed over a series of late-night high tides lasting three to four evenings.
What are the best tips for finding grunions on grunion runs?
-
Find a sandy beach with access to open ocean - avoid harbors and lagoons
