Diver's Notes

Beautiful clear sunny skies and hot weather. Sea conditions were good with infrequent small waves. But once in the water there was a strong North-South surge which made swimming through the channel difficult at times. The arch was a litte murky but on the other side it cleared. Schools of silver sweep and one-spot puller but most of the fish weren't the type to stick around for photos. We followed the channel to the arch then out over the boulders before turning at 120bar to return north to the shore back through the arch and up over the kelp beds.
