In the waters around southern Vancouver Island, we’re most likely to see killer whales from April to October.  We have had a great resurgence in humpback sightings as well! Our season is from March 1st until December 31st. Unlike people, whales are not on a 24-hour clock, and so the time of day does not influence the likelihood of sightings – We always advise to chose the time that suits your schedule and other plans during your visit to Victoria.
