On the Oregon Coast, several whale species, especially gray whales, may be seen year-round, and the state trains volunteers to assist tourists in the winter months, during whale migration season. In California, good whale-watching can be found year-round on the Southern California coast. During the winter and spring (December–May), gray whales can be seen from shore on their annual migration (the best spot being Point Vicente), while blue whales are often seen between July and October. Fin whales, minke whales, orcas, and various species of dolphins can be seen year-round. In spring, summer, and fall at the Farallon Islands off San Francisco, one may see humpbacks, grays, and blue whales.
