I've always enjoyed Monastery as a shore dive myself, though we haven't done it since we got our boat. Now we can dive pretty much anywhere in Carmel for similar conditions. The cool things about Monastery are a)very few shore dives allow you to go to true depth on a single tank-Monastery, you can go as deep as you want and generally get back to shore because of the steepness of the hill. b)Ocean exposure gives generally clear vis as long as the swell is coming from the normal direction. c)One of the easiest natural navigation dives you'll ever do, just follow the kelp bed out to the wash rock, hang a right and boulder hop downward.
On the other hand, don't get fooled by Ma Nature. If the waves are breaking over the wash rock, don't get in no matter what the beach looks like. You'll get pummeled and spun like a washing machine. The beach is so steep that you're under water two steps from shore and the wave action pretty much pounds straight in and blasts you into the sand. Other downside is that stupid pea gravel (Monsterberries) gets in your reg, your suit, your boots and everything else. Always rinse your gear good and check your reg after you get out.
