I have dove Redondo many many times.
I have never noticed a current.
It is one of my favorite sites to take a new or out of state dive buddy.
with no currents to worry about ~ almost unheard of in the PNW ~ Its a great site for that checkout dive.
As a photographer it is a great critter spotting site.
I have seen GPO's, Sailfin Sculpins, Red Octo's, Salmon, Skates, Nudibranches, Ling Cod, Stubby Squid and tons of Rockfish (the list is almost endless) to name a few critters that live there.
Enjoy your OW class.
I hope your instructor allows time to take you on a tour. There are always tons of crabs and sea stars in the area.
