The Best Months for Whale Watching from Anacortes
May to October, peaking in high summer, with humpbacks strongest in autumn.
The San Juan season runs May through October.
June to August — peak
Highest orca activity, calmest seas, longest days. This is when sighting odds are best across species and when the boats are busiest. Book ahead.
September and October — the humpback window
Outstanding for humpbacks, which have returned to these waters in numbers over the past decade, and with noticeably fewer people. Bigg’s orca activity holds steady into early October. If you want the best trade between odds and crowds, come now.
March to May — grey whale migration
Grey whales pass through the Strait of Juan de Fuca heading for Arctic feeding grounds, and can turn up on trips out of Anacortes. A different animal and a different, shorter window.
Outside the season
Boats largely stop. The animals do not entirely leave, but the operations that take you to them do.
What does not change
The distance rules, and the fact that these are wild animals in open water. No month guarantees anything; some months load the odds better than others.

Book the Sailing, Not the Weather
Trips run on a schedule and the sea does not. Booking ahead holds your place on the boat and keeps free cancellation up to 24 hours, which matters more here than the price does.
