PORTLAND, Ore., July 9 (Reuters) – Researchers have declared a “catastrophic mortality event” for gray whales on the West Coast. 145 carcasses have been found so far in 2026. This is on track to be the deadliest year on record.
According to the Center for Biological Diversity, 60 total whale deaths—across all species—were recorded by July. The majority are gray whales. Fatalities cluster in Washington state, the San Francisco Bay area, and Southern California.
This surpasses the 2019-2020 die-off, which saw roughly 70 gray whales strand. That event was also labeled unusual. 2026’s pace is unprecedented.
The primary driver appears to be malnutrition linked to Arctic feeding ground collapse. Reduced sea ice cover has diminished populations of amphipods and krill. Gray whales arrive on migration emaciated. Ship strikes and fishing gear entanglement compound the crisis.
Hotspots align with major shipping lanes. In February, a 30-foot humpback washed ashore near Los Angeles. The pattern is consistent: starving whales veer into traffic.
The economic ripple is immediate. Whale-watching operators in Monterey Bay report a 40% drop in bookings. Local fisheries face scrutiny as gear is blamed for entanglements.
NOAA has not declared a formal emergency. The Center for Biological Diversity has petitioned for mandatory speed limits in migration corridors. Ropeless fishing gear trials are underway, but adoption remains voluntary.
If mortality continues at this rate, the Eastern North Pacific gray whale population—currently estimated at 14,500—could face a structural decline. 2026 is not an anomaly. It is a signal.
| Metric | 2026 (Jan-Jul) | 2019-2020 Die-off |

💡 Frequently Asked Questions (FAQ)
- Q: Why is 2026 considered the deadliest year for gray whales on the West Coast?
- A: As of July 2026, 145 gray whale carcasses have been found, surpassing the 2019-2020 die-off. The mortality rate is unprecedented due to malnutrition, ship strikes, and fishing gear entanglement.
- Q: What is causing the gray whale die-off in 2026?
- A: The primary cause is malnutrition linked to Arctic feeding ground collapse, reduced sea ice, and diminished amphipod and krill populations. Ship strikes and fishing gear entanglement worsen the crisis.
- Q: How does the gray whale die-off impact local economies?
- A: Whale-watching operators in Monterey Bay report a 40% drop in bookings, and fisheries face scrutiny over gear-related entanglements, leading to economic ripple effects.
- Q: What actions are being taken to address the gray whale mortality?
- A: NOAA has not declared an emergency, but the Center for Biological Diversity has petitioned for mandatory speed limits in migration corridors. Ropeless fishing gear trials are underway but voluntary.
