Previous studies indicate that the southward migration through Oregon lasts about two months (Herzing and Mate 1984). However, 90% of the whales migrated past Yaquina Head between December 19 and January 23. The northward migration through Oregon is divided in two phases. Phase A, which comprises adults without calves, begins during the last week of February with a peak in mid-March.
Time your adventure carefully during the whale-watching season to maximize your chances of seeing plenty of orcas. Generally, the best time to see these whales in the Washington area is in the spring, summer and early fall, from April to early October. During this part of the year, orcas are plentiful, as it's the best time for whales to find runs of salmon in the water.
