Onjuku Surf Forecast and Surf Report

Alright folks, Rusty here. Let's have a look at what's on the table for the next couple of weeks at Onjuku.

Honestly, the next week or so is a grind. We’ve got some small, weak energy bumping around, but the wind is mostly cross or onshore, so the quality is just not there. The water temp is about 80°, which is bang on average for this time of year, so at least you won’t be freezing while you’re sitting there waiting.

It’s not until the end of next week that things start to get interesting. There’s a solid run of south-southeast groundswell building from Monday the 24th of August, with the combined energy jumping way up into the thousands (1313 on Monday morning, then ramping to 4472 by the afternoon). That’s a serious amount of energy in the water. But here’s the catch – it’s all onshore wind. The period is long, hitting 17 to 18 seconds, which is proper groundswell, and a swell over 8 feet like the Monday afternoon reading of 8 ft is expert territory only, especially with the onshore chop. The break is exposed to the SSE, but with strong south winds, the surface will be messy.

Now, the real standout is Wednesday the 26th of August. The morning session there is the pick of the whole outlook. We’re looking at a solid 12 ft swell from the SE, with a period of 13 seconds. That’s big, powerful groundswell. The wind is cross-offshore from the east at 9 mph. The combined energy is a massive 4382. That’s a lot of grunt. The catch here is that the file calls it “too big for this break” – 12 ft is going to be a washing machine, proper heavy and likely closing out for most. This is strictly for expert-level surfers only. If you’re not on your game, sit this one out. But for the crew that can handle it, with that offshore wind, it might be a wild, memorable session. On Wednesday afternoon, it drops back to 8 ft from the ESE, still clean with cross-offshore wind, making for a much more manageable, still powerful option for strong intermediates and above.

After that, the swell fades fast through the end of the month, with the wind going back onshore or becoming too strong, so don’t sleep on that Wednesday morning window. It’s a long way out, so keep an eye on the forecasts, but that’s the one to circle on the calendar.

Rusty.
