If you bring a buddy, warm clothes, and beer (if you're so inclined), you'll have a blast. I've always done best around high tide, but you can get into stuff at any time, just better bite towards the tide swings. Low slack can be good too. Any hour of the day (again, better at night). Every now and then, you might even hook into a ling this time of year, but don't bet the rent on it, and they're hard to land on the jetty. And if you cast to far past the rocks and get into the sandy bottom, I've seen (once) and heard stories of hooking into skates... which you'll never see, and might cost you a spool of line. Might as well be hooking a submarine.
Way back when, a friend and I used to go at night in winter to our "private, secret rockfish hole," which is quite public, and never gets fished -- the rock piles around the ramp at Netarts. We'd toss a crab trap off the dock (no one is usuing the boat ramp at night), walk out on the rocks and chuck light jigs on light rods. Rarely catch anything of any size, but usually got plenty of action, and would get a few crabs, mostly redrock. We could park right next to where we were fishing, had restrooms with running water, heat in the truck if it got cold... and a bar across teh parking lot. We'd get pretty tossed, catch fish, sleep it off in the truck, and if there was a somewhat low tide in the morning, go down to the crazy clam beds (tough digging in the rocks, but lots of big gapers/blues there, although I'm not much of a clammer). Haven't been there in many years (else I wouldn't be sharing my "secret hole"), but that was always a good time. Barview definitely has better fishing, though.
Have fun, young man
