A fin whale needs deep, open water, so no inland refuge or park is real habitat for the species. Every credible California record comes from boats offshore or along the coast, mostly whale-watching trips and research surveys around places like Monterey Canyon and the Channel Islands.
Reports actually peak earliest in spring, climbing to 51 in April before easing off, rather than the summer high some seasonality summaries suggest. That April bump likely tracks when whale-watching boats and researchers are most active off central California, not a true migratory schedule.
Slightly more than half of the state’s 260 records come from iNaturalist photos (229) versus museum and survey data (196), a fairly even split that’s unusual for a large whale and points to how often fin whales are photographed from tour boats and shore. Globally the species is listed Vulnerable, and in California’s own record comparison it lands in the middle tier, neither rare nor routinely documented.
