when would whales migrate past oregon
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.
Approximately 20,000 whales migrate southward past the center from mid-December to end of January each year. The same number migrate northward, but are distributed throughout mid-March through the first week of June. Gray whales are the most commonly sighted whales year round along the Oregon Coast.
