US EditionGray Whale Death Toll in San Francisco Bay Climbs to 14
- Researchers found five dead gray whales around the San Francisco Bay Area between May 21 and May 26, 2025.
- This event follows an unusual rise in gray whale sightings and mortality in 2025, with 33 whales spotted and 14 deaths recorded, while the cause remains unclear.
- The dead whales were located at Bolinas, Berkeley Marina, Southeast Farallon Island, Point Bonita, and Alcatraz Island, and necropsies are not possible due to decomposition and difficult access.
- The California Academy of Sciences noted that although the cause of death for the five whales this week remains uncertain, collisions with boats—including everything from big commercial vessels to smaller sailboats—represent a significant threat to whales.
- Officials expect gray whales to resume their northward migration soon and advise boaters to be “whale aware” and slow down to reduce strike risks in the Bay.
