Onjuku Surf Forecast and Surf Report

G'day, Rusty here. Look, I gotta be straight with you—the next 16 days at Onjuku are a mixed bag, and we're starting off with a bit of a dud before things get interesting. The first few days are a write-off, but there's a glimmer of light later on.

We kick off on Wednesday, August 26th, and it's a shocker. The swell is a tiny 3 ft from the SSE with a short period of 10 seconds, but it's blown out by a cross-onshore wind. The energy is moderate (353), but the surf is just poor. Thursday the 27th is a little better. The swell drops to 3 ft from the SSE, but the wind swings to a light cross-offshore in the morning, making things clean. The combined energy is moderate (330). The afternoon cleans up even more with a gentle offshore breeze from the NNE and a nice 2 ft swell from the east with a 13-second period—that's a proper groundswell. The energy is solid (290). This is about as good as it gets for the first week, but it's still small, ankle-to-knee high stuff.

The 28th and 29th are a write-off with poor surf and messy winds. Then Sunday, August 30th, has a glassy morning with a tiny 2 ft easterly swell (11 sec period) and weak energy (93). It's surfable but very ordinary. The rest of the week is much of the same, with small, clean conditions but no real power.

Now, hold onto your board. The standout is on Tuesday, September 8th. The swell is huge, with a 13 ft to 15 ft SSE swell rolling in. The combined energy is massive (4536-5031), and it's a long-period groundswell at 12 seconds. The wind is moderate cross-shore to cross-offshore, keeping things somewhat clean. Here's the catch: this is way too big for beginners and only for experts. It's a long-period swell, so it'll be walling up a bit at the beach break, but for the experienced crew, it's going to be a proper session. The water temperature is about average for the time of year, but with that much energy, you won't be thinking about that.

The 9th and 10th of September see the swell drop back down, but it's still sizeable at 7 ft, though the wind is strong and cross-offshore, making it a bit of a battle. The whole period is a slow burn, but that one day on the 8th is the only real standout. If you're not an expert, the best bet is the small, clean conditions on Thursday the 27th.

So, for the first week, it's a lot of waiting. The second week brings the monster, but it's for the brave only. Stay tuned, forecasts can change.

Rusty.
