North/south... depends on the wind. Granted with the north jetty you have a little more options because of the boat cut.
I fish the south when I fish the jetties just because I don't care for riding the ferry across. Also, this time of year with the colder water the south is harder to access since there is a break in the jetty about 50 yards down... it is rather dangerous. It can be walked around though on the sandbar that is inside on the channel side. then you just have to find the right place to get back up onto the rocks.
If it was me, and I didn't have waders and I wanted to fish the rocks... I'd hit the north jetty and head to the boat cut area.
On the surf side of the jetty, near the boat cut, se a 1 ounce drop weight and use a 35b fluor leader or steel if you want. Use a 4/0 range circle hook and cut mullet or cut shad. Cast between 20 yards and 40 yards away from the boat cut or fish the rock base near the boat cut but try not to get hung up on the rocks on the surf side.. it's about 6-8 feet deep sandy bottom except for the rocks.
On the channel side.. it's different.. it's 40 feet deep and all rocks sloping away from the top of the jetty falling into the depths of the channel. There can fish along that side but not getting hung up is a ****** . You can catch some fish on that side, but you need more weight and a lot more rigs because you're going to lose a lot. The only way I found to fish the channel side is when the tide is slowing to almost slack and use a bobber stopper to keep it off the rocks. Throw it up current (watch out for others lines) and then allow it to work the rocks as it slowly moves along with the current. try to set your bobber stopper knot at about 8-12 - 15 feet. Look for some you tube clips on how to use a bobber stopper knot on a float. You don't have to make long cast with this method.. you'll have to work between people and make shore 20-30 foot cast along the rocks at varying distances out from the rocks depending on how deep you have the knot so the cork just floats the rig off the rocks and moves it along with the current. Those fish are sitting in the turbulence along the rocks and even behind rocks that stick up or even in gaps in the rocks.. all of which you can't see from the surface. Weight on the end of the bobber stopper rig .. probably a half ounce.. all you want is for it to get done without pulling your cork under. Use a 12 " leader or steel and same circle hook.
You can also freelance live drip or dead shrmp with a small hook and catch smaller fish up shallower by your feet in the rocks on both sides.
Be careful.. it's winter and the water is cooling off fast with the last front.. Wind and a little wetness with no sun can be a bad situation fast.
hope that helps.
