I agree with the push difference. Seems like things changes dramatically every few seconds of period. A few things to consider about longer period waves. A larger portion of the energy travels underwater in deep water, and that energy translates to push and lift as the wave moves into shallower water.
On a sand bottom, the change in depth is gradual, so the wave wants to throw very quickly all together unless the swell is either coming in at a very drastic angle, or better yet, there is a little bit of wind swell crossing it up and creating peaks.
On a reef, there is shallow water next to very deep water. And the swell draws up on the reef, there can be a very strong bowling effect, where the peak is steep, round and throwing, while very near by the swell is in deep water and too flat to catch. The trick is to track down that peak as it is starting to be effected by the reef, and the lift/push allows you to paddle in, and the waves almost feels slow, because the transition is smooth and the waves catches you. Obviously positioning and timing is key, but if done right the take off is way simpler than tracking down and paddling into shifty, weak beach break.
Now, actually getting barreled in these conditions is still a challenge, even in very good waves. All that push and lift provides tremendous speed down the line that must be slowed and controlled. And that can be hard. And even once you slow and get inside, you then need to make sure you have the speed to get out.
Sounds like you were on a point break, which is a whole different beast. The wrap tends to make the waves softer, but lined up for longer sections. Points can be powerful and hollow, but those points tend to have more reef pass characteristics (with a quick shift from deep to shallow). I actually find points a bit more challenging because they don't typically have a distinct, concentrated peak, but the take off can shift through a zone. Also, and partly because of this, the take off is flatter, which tend to be easy to make, still require more paddle power to catch, because they don't really catch you. Unless you are using the lip/foam to push you in. Still, at size, they require you to get up and going and making sections as they peel. They can require you to chase down the line.
Of course every single break is different. Some reefs are mushy, some points are short, some breaches break from 2-20 feet or seconds, some never work at all, and there are coves, river mouths, passes, fjords, bores, ledges, cobbles, boulders, continuous, gapped, groins, piers and combinations of all of there. One of the things I like about surfing is getting to know when to go one place, and when to choose another.
Had to make a call last night, and was stoked on my choice. Mid to low tide dropping, 5.5'@11s was perfect. Fun, shoulder high bowls. It is a ledgy reef, and usually longer periods to be working. I surfed it last week when it was 5-6@20. That day was much bigger and juicier and the tide was fuller. Usually I consider 13s to be about the cut off for this spot. I was not so sure about my call, but drive time and sunset help dictate. That lower tide worked perfectly. So much fun. And one guy out. Just enough to make me not focus on the smell of rotting seal carcass.
