Tuna	Peaks from August through October. Yellowfin and bigeye tuna are found at Catalina Island, 30 minutes from the beach where schools of 12-to 20-pounders are abundant. There are frequently large concentrations of 40- to 60-pound tuna and there are plenty of 200- to 400-pounders caught every year.
Wahoo	Season begins with the May rains and peaks in July and August. They are caught around rocky points and islands and occasionally offshore.
