Onjuku Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get into it for Onjuku.

We’ve got a run of surf on the way, but you’re gonna have to be patient. The next few days are a bit of a write-off, but there’s a proper window of clean, solid waves coming up for the experienced crew.

The first real chance to get wet is Sunday morning, the 9th of August. It’s waking up with a clean 1ft swell from the ESE, and the wind is light and cross-offshore. That’s a lovely combo. The water’s sitting about average for the time of year, so no surprises there. The combined energy is pumping at a solid 1131, so there’s plenty of push. This is the standout of the whole forecast. Sunday afternoon holds the same size and quality, just a touch more breeze. The swell period is a solid 13 seconds, so it’s proper groundswell – that’s going to line up nicely.

Monday the 10th sees the swell kick up a notch with 1ft to 1ft from the East, period dropping to 12 seconds. The wind stays cross-off, but it’s a fresh 30 km/h, so the surface will be clean but blown out. The energy is between 1399 and 1545 – strong. This is getting into the ‘experts only’ zone size-wise. It’s not a standout because the wind is strong, but it’s there for the brave.

We hit a major lull from Tuesday the 11th through to Thursday the 13th. The wind turns onshore and choppy, and the swell drops right off. On Thursday morning the 13th, the swell comes back up to 1ft from the East with a moderate cross-off breeze, but it’s only a 2/10 situation. The energy is low at 726. You’d be scratching for a decent one.

Friday the 14th and Saturday the 15th we see size again, with 1ft to 2ft East swell, but the wind is howling at 30-35 km/h. The energy is right up there, especially on Saturday morning hitting 3072, but the onshore texture makes it messy. Sunday the 16th is also tough with onshore wind.

Now, here’s the second promising window. Monday the 17th of August morning. Don’t sleep on this. It’s glassy. Surf is 1.0ft from the East, period of 10 seconds, and the wind is literally a dead flat calm with a “slight air”. That’s as clean as it gets. The energy is moderate at 524, but the glassy conditions will make it look a million bucks. It’s a good option for the intermediate crowd. The afternoon turns choppy, so get out early.

The rest of the week into the 23rd is marginal. Swell hangs around 0.9ft to 1.0ft, winds are mostly cross-off, but the energy is low and the consistency is patchy. The 23rd of August sees a very long period groundswell of 16 seconds, but it’s a tiny 0.5ft with messy cross-shore wind. That’s a no-go for a beach break.

So, to wrap it up: your best bet is Sunday the 9th of August for the combo of size, clean conditions, and proper groundswell. The second shout is the early glass-off on Monday the 17th of August. The rest of the run is a mix of too much wind, too much size for the average punter, or just plain flat. The crowd at Onjuku can be a factor sometimes, so keep that in mind on the good days.

Rusty.
