Are there still opportunities to view Orcas during the first part of August?
I believe so. I took a cruise in 7/5 and we saw Orcas and I reviewed my photos from last year and I have photos of Orcas in August. There is a difference in that after 6/10 there is no longer a cruise dedicated to just Orcas. However as noted above it is still possible to see them.
