Can somebody explain somethings about Northern Cal?

Hey, new to this forum but have got a lot of good info in the past from here so I knew this was a good place to ask this question. I hope this is the write subforum or whatever, but first of all I'm from socal and I've been surfing for a couple of years at my own pace messing around, not doing crazy top to bottom surfing or any cutbacks but heres where everything ties in. I was gifted a pretty thick shortboard when I was like 20 and thats how I learned, I never seemed to had problems paddling for waves or matching the waves speed and was having a blast everything was beautiful. I moved up about 50 miles north of San Fransisco in the summer for some work and did some exploring and had a really good time, but once things started getting bigger and working a bit better, I went down to a spot thats alot like OB(which I haven't check out yet) that's pretty well known called Salmon Creek. This is the spots all the locals were telling me to go, I've gone a few times, once was like some kind of blessing and had nice powerfull glassy and hollow overhead barrels. I remember one paticularly choppy saturday morning and theres about 40 guys there, cool this is more my speed, I was the only guy with a shortboard everyone else had an egg or a longboard. Everywhere I looked eggs all over the place and in different sizes. The wind was only like 7 mph but magic sea weed was giving it loooow ratings and everywhere else was just saying it was a choppy mess. I have never paddled out into something that weird, thank god I was able to duckdive or I would've just gotten crushed all day. Paddling out took me maybe close to 20 minutes, I felt like I was moving in place and getting back in was way worse. I'm still very new so maybe I can adjust to this but , even the local shops only carry these eggs and they are very traditional everyone has very flat nose rocker. I deffinetly want to try the shape now because I never have and I do think people are using them because of how hard it is to get out, but if I'm wrong I want to know what it is, just seems counter intuitive when you have to get out back without being able to duckdive all the way and then drop in on a super steep wave with a longer flater board. If theres any other things I should know about Norcal, aside from the obvious stuff like how much heavier and more water gets moved in the waves and sharks
