Balaenoptera acutorostrata
At 30 feet, minkes are small enough to mistake for a large dolphin, but the bright white band across each flipper is definitive. Solitary and fast, they surface unpredictably — your best chance is the kelp lines off Dana Point and the outer Channel Islands.
There are only about 915 minke whales in the entire California/Oregon/Washington stock, which is why sightings are uncommon overall. Individuals appear to hold coastal home ranges, so a single operator working the same kelp line can encounter them far more often than that number suggests.
HOW RARITY IS JUDGED →Newport & Long Beach operators share daily trip counts — you can see what was spotted before you book. Other operators don't publish daily reports.
