When do the grunion run?

Typically, the grunions make their way back into the ocean between the months of March and August, with peak runs in April through June. Runs are predicted a year in advance because of the regularity of the grunions. Many workshops for Grunion Greeters are scheduled in various cities in southern California a month or two before the predicted run. Click here for workshop information.
