I would recommend coming here in May/June vs Feb. Winters here, the prevailing swell is from the NW, and with your very limited experience you would be dealing with somewhat trickier swell situations on shore dives.
Honestly, with only 10 dives under your belts, I would recommend hiring a guide for the shore stuff. You need to be able to read the wave sets and get some perspective on the conditions. You would also see a lot more critters, etc. and learn all about entering and exiting shore dives, which is knowledge you will use the rest of your life.
I also cannot say enough about doing some boat dives as well. Nearly all the operators here put a guide in the water, who will point out some cool stuff you would otherwise most likely miss. And they do a fine job of giving you a very nice day out on the water, especially new divers.
