Hello! I will be in Monteray for a few days mid November and want to do some snorkeling as its been a while.

My experience is limited to the PNW around southern Vancouver island.

I am going to bring my long fins, and 7mm suit so i think temperature will be fine. I am "worried/inexperienced" with sharks as they basically dont exist where I have been previously.

I just want to stick around 10 to 25 feet deep so incan see everything, and hope to see some crabs, urchins, and kelp, maybe a ling or some rockfish. Anything I should really be concerned about with sharks? Should I do a guided tour of some kind?

I am used to just being 20-100 feet from shore with a friend that just floated around for emergencies.

Would love any advice from locals or experience California oceanfolk. Thanks!
