If you book a "gray whale" cruise out of Channel Islands Harbor in January, which whale are you most likely to see? Last winter, the honest answer was a humpback.
That shows up in a sighting table Island Packers keeps for every vessel in its fleet. Island Packers' 2026 marine mammal summary logged 84 humpback sightings and 59 gray whale sightings in January. In February it logged 200 humpbacks and 87 grays. The gray whales did show up in force eventually, but only in March. For anyone in Hollywood Beach, Silver Strand or Mandalay Bay planning a winter trip, or a holiday visit from whale-curious relatives, the season label and the most likely sighting don't line up the way they used to.
What the boats logged, January through April
These are Island Packers' 2026 totals for all of its vessels, which sail from both Oxnard and Ventura. They count sightings, not individual animals, so a whale seen on two trips counts twice. The table works for timing and doesn't work as a census.
| Month, 2026 | Humpback sightings | Gray whale sightings | Orca sightings |
|---|---|---|---|
| January | 84 | 59 | 0 |
| February | 200 | 87 | 6 |
| March | 42 | 199 | 0 |
| April | 108 | 11 | 6 |
Over those four months, humpback sightings came to 434 and gray whale sightings to 356. Grays led in only one month, March, and they led by a lot. That month's 199 gray whale sightings were more than January and February combined. By April the gray count had dropped to 11 while humpbacks were back above 100.
Dolphins appeared on almost every trip. Common dolphin sightings reached 90,150 in February, and bottlenose dolphin sightings ran from 759 to 2,202 a month over the same stretch. Even on a slow whale day, a trip out of the harbor isn't an empty ride.
Humpbacks no longer leave for the winter
The humpback numbers are part of a larger change that local crews have been describing. The Ventura County Star reported in December 2025 that whale-watch boats were seeing humpbacks nearly year-round off Ventura. For years before that, humpbacks mostly stayed in the Santa Barbara Channel during the summer.
Island Packers' own 2026 table follows the same pattern. Humpback sightings stayed between 81 and 200 a month from May through July, after the grays had moved on. Winter trips now overlap with whales that used to be a summer attraction, which is why a December or January cruise can turn up more humpbacks than the species it's named for.
Gray whale numbers point in two directions
Whether March will be as strong this coming season depends partly on how many gray whales are out there, and the two main counts disagree.
In July 2026, NOAA Fisheries released a new estimate for the Eastern North Pacific population, the gray whales that migrate along this coast. It puts the population at about 17,750, in a range of 15,930 to 20,530. The previous year's estimate was about 12,890, one of the lowest since counting began in the late 1960s. That's a jump of roughly 38 percent, and NOAA's researchers say it likely exceeds what the population could produce through births. The agency's last calf estimate, for 2025, was 85, the lowest on record. NOAA says the increase may reflect changes in how the whales migrate or in the assumptions behind the survey. NOAA also reports that strandings over the past two years have climbed back into the range seen during the 2019 to 2023 unusual mortality event. Many of the stranded whales were thin or emaciated. For perspective, the population peaked at about 27,000 around 2015 and 2016.
The volunteer shore count farther down the coast is lower. The American Cetacean Society's Los Angeles chapter runs a gray whale census from the Point Vicente Interpretive Center. Its 42nd season ended May 25, 2026, with 214 southbound gray whales, its second-lowest southbound count after the previous season's 130. The northbound count was 445, a new record low. Calves were the good news. Volunteers counted 17 southbound calves, up from zero the season before, and 16 northbound, up from 8. The census director called the result "cautious optimism."
Taken together, there may be more gray whales than recent years suggested, but fewer are passing close to shore, and calf numbers are only starting to recover from very low levels.
Matching the boat to the month
Two operators run winter whale watches from the harbor's east side, and their seasons start at different points.
- Island Packers runs its winter whale watch from December to mid-April, with departures from Oxnard and Ventura. The Oxnard cruise is listed at 3.5 hours, with fares of $45 for adults, $41 for seniors and active military, $32 for children, and free for infants.
- Channel Islands Whale Watching gives its season as December 26 through April 30. Its tours typically run three to four hours. Its partner, Channel Islands Sportfishing, lists $70 for adults, children, seniors and active military. Channel Islands Harbor's directory lists the operator at 4151 S. Victoria Avenue.
Last winter's table gives each part of the season a different purpose. A December or January trip is a good bet for humpbacks and large dolphin pods, which suits holiday guests who want a lively first time on the water. February was the strongest overall month, with 200 humpback sightings, 87 gray whale sightings and the year's first orcas. March was the gray whale month, so if grays are the goal, book then. April brought humpbacks back and a second set of orca sightings, but very few grays. With the gray whale counts this unsettled, it's also worth checking the sighting table again as the season goes on.
From shore, and on the shipping lanes
For a free look, the Ventura County Coast visitor guide points to Mugu Rock and names February and March as good months to watch from there. That window matches the gray whale build-up in the boat data. The Ventura County Star has also named Sycamore Canyon in Point Mugu State Park as a good land-based spot. Both are a short drive south along the coast from Silver Strand.
Farther offshore, big ships in the channel are being asked to slow down. The Protecting Blue Whales and Blue Skies program asks vessels over 300 gross tons to travel at 10 knots or less from April 22 through December 31, 2026. NOAA notes that the voluntary speed-reduction zone expanded statewide this year. That season ends just as the harbor's own whale season picks up.

The harbor's busiest whale months fall in late winter, which is also when many homeowners start thinking about spring.
