July on the month list
AllWater lists July for Avalon Harbor, so that is the month to put on the calendar first.
Later in the summer
FishingBooker says yellowfin arrive later in the summer. Treat this as a separate window from the AllWater listing.
Where boats run from Avalon
Per the Bdoutdoors guide to Catalina Island, boats run for yellowfin just offshore of the island, in open water. The run starts from the same harbor you fish the island from.
Open water just offshore
Bdoutdoors places the yellowfin fishing in open water rather than on a rock or bank. The named rocks and banks are covered below as local grounds. Plan the day around the open water first and the structure second.
Beyond the island
For the wider offshore picture beyond Catalina Island, see the Southern California regional guide (see also the wider Pacific Southwest guide).
