In a dramatic change, whales are now hanging around in San Francisco Bay
Published in the San Francisco Chronicle: May 14, 2022
In decades past, humpback whales almost exclusively swam past the bay and stayed offshore during their annual migration from April to October. Now, a rising number are coming closer to the coast. Some venture into San Francisco Bay during peak season, and a few even stay in nearby waters year-round.
The new behavior is attributed mostly to a boost in their population and warming ocean temperatures, and the changes have major implications for everyone from tourists to the shipping and crab industries.
