Onemana Surf Forecast and Surf Report

Alright, listen up. Rusty here.

Right off the bat, the next week or so is looking pretty flat and uninspiring for Onemana. There’s really nothing on the table that’s going to get the heart pumping. We’re looking at a real dry spell. The wave energy is just piddly, with combined energy readings often below 100, like 88 on Saturday the 1st, and sometimes way down in the teens and twenties. It’s tiny, weak, and just not worth the paddle.

We’ve got a few glassy mornings here and there, and the water temp is sitting at about 58.5°F, which is pretty much normal for this time of year. But the lack of swell is the main story. We’re seeing those little 0.7ft to 2.6ft waves at best, even if the conditions are clean sometimes, it’s just not surfable. There is a brief bump in the energy on Friday the 7th and Saturday the 8th, with some 3.3ft to 4.6ft waves from the north, and energy climbing to 172, but the quality is still poor. It’s just messy and confused.

Here’s the thing to watch though. Starting on Sunday the 9th, the ocean wakes up. We see that energy jump hard to 411, with 6.6ft of east swell. That morning is glassy, but it gets blown out quickly in the afternoon. Monday the 10th sees it get bigger, up to 9.8ft and the energy is over 1000, but the wind is onshore and it’s all chop. This is where things get serious.

Then we hit the big one. Tuesday the 11th and Wednesday the 12th. The swell just detonates. We’re looking at a solid 16.4ft from the ENE with a 12-second period, and the combined energy is absolutely pumping, over 6000. This is a big, raw, powerful ocean. That’s easy 8ft+ territory which is strictly expert-only. The guidance says the wind and tide are favorable, but the sheer size is just too much for this break. This is not a paddle-surfing setup unless you’re absolutely charging. Stick to watching this one from the cliff.

Once that massive pulse eases off, we finally get our window. Thursday the 13th is the standout. The swell has dropped to a still-chunky 7.9ft in the morning, dropping to 6.9ft in the afternoon, coming from the east with an 11-12 second period. The wind is light and glassy in the morning and clean cross-off in the afternoon. Combined energy is still strong, around 1846 in the morning. The guidance is calling it “excellent surf conditions for experienced surfers,” and I’d have to agree. This is the best of the whole 16-day stretch. It’s big, powerful, and clean on the face. Onemana is a fairly consistent spot and fairly exposed to that east swell, and with that light wind it’s going to be worth the effort.

After that, things back off again. Friday the 14th still has some decent 4.3ft waves from the east with offshores, clean and fun, but it’s a noticeable step down. From Saturday the 15th onward, it fades back into the small stuff, with energy dropping back under 400 and then below 100. It’s done.

So, the play is clear: skip the small stuff, watch the massive pulse from the 11th and 12th, and be ready for the main event on Thursday the 13th. That’s your session.
