NOAA's Gulf of the Farallones National
Marine Sanctuary Asks Bay Area
Boaters to Watch Out for Whales

NOAA's Gulf of the Farallones National Marine Sanctuary advises San Francisco Bay Area boaters to watch out for and steer clear of whales, which migrate into the San Francisco Bay Area in large numbers during the spring and summer. Gray whales are at a particularly high risk of collisions with vessels, as they often travel near shore and may even wander into the bay. San Francisco Bay and Tomales Bay always have a few springtime gray whale visitors.

Boaters should use caution year-round, but springtime presents a greater chance of coming into close contact with whales. From March through May, thousands of migrating gray whales make their way north from breeding grounds off Mexico to feed in Arctic waters near Alaska. Many of these whales travel through busy shipping lanes off San Francisco in the Gulf of the Farallones sanctuary just outside the Golden Gate.

While they also migrate south through the sanctuary in the winter, gray whales - including mothers with newborn calves - swim closest to shore in the spring. Cow-calf pairs can sometimes be seen from shore, and may even pause in the surf zone for the calf to nurse or rest, and to avoid killer whales.

Boaters should watch for the gray whale's blow, which looks like a puff of smoke about 10 to 15 feet high, since very little of the whale is visible at the surface. A whale may surface and blow several times before a prolonged dive, typically lasting three to six minutes.

Boaters should not:

  • Approach within 300 feet (the length of a football field) of any whale
  • Cut across a whale's path
  • Make sudden speed or directional changes
  • Get between a whale cow and her calf - if separated from its mother, a calf may be doomed to starvation.
Each year, thousands of ships and smaller vessels pass through the Golden Gate. Even small-craft collisions with a whale can have disastrous results for both whale and vessel. All whales are protected by the Marine Mammal Protection Act. Some local species, such as humpback and blue whales, are also protected by the Endangered Species Act.

NOAA's mission is to understand and predict changes in the Earth's environment, from the depths of the ocean to the surface of the sun, and to conserve and manage our coastal and marine resources. Visit us at www.noaa.gov or on Facebook at www.facebook.com/usnoaagov.
