Onjuku Surf Forecast and Surf Report

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

Right off the bat, the first few days are a bit flat. We’ve got a tiny 2ft SSE swell on Friday afternoon, but it’s onshore and weak, with combined energy of just 63 – not worth paddling out for. Saturday morning shapes up a little better with a glassy 1ft SE swell, but it’s gutless. The water temp is a pretty standard 80°F for this time of year.

Things start to get interesting as we head into the following week. Sunday the 2nd and Monday the 3rd see a long-period groundswell from the SE pushing in. The swell jumps to 4ft on Sunday morning with a 16-second period, and combined energy hits 618. That’s a serious pulse of energy, but the wind is a cross-off shore from the NE, which will keep things clean. The swell direction (SE) is a good match for Onjuku’s optimum SSE. By Monday morning, we’re looking at 7ft at 17 seconds, with energy surging to 2563 – this is moderate to strong. This is a proper groundswell. However, with that long period, it might be a bit too straight for the beach break, but the point could handle it. This is the first real standout window. The best of the bunch is likely Monday morning, the 3rd of August, with 7ft SE swell, 17-second period, and clean cross-off winds.

Now, be warned: from Tuesday the 4th through to Thursday the 6th, the swell goes absolutely nuts. We’re talking 12ft to 15ft SE swell with energy readings in the 6000 to 9000 range. The wind is cross-off, which is clean, but the size is excessive. This is a heavy, expert-only zone. If you’re not a seasoned charger, stay on the beach. That kind of power and size with a 16-second period is going to be a washing machine.

After the big stuff drops, it settles into a more manageable range. Friday the 7th and Saturday the 8th offer 5ft to 8ft S and SSW swell, but the wind goes cross-onshore, chopping things up. Not great.

The real second standout arrives on Sunday morning, the 9th of August. We’ve got a clean 5ft ESE swell, with a 13-second period, and light cross-off winds from the ENE. The combined energy is a solid 1090. This is a much more user-friendly size, and the conditions are clean for experienced surfers. The swell direction (ESE) is a bit off the optimum SSE, but it’s still workable.

The following week sees a lot of onshore or strong winds, which limits the quality. Monday the 10th is blown out by strong NE winds. Tuesday the 11th has a 7ft E swell with offshore winds, but the wind is strong at 22 mph, making it a tough paddle. Thursday the 13th morning is a standout with a clean 6ft ESE swell and gentle offshore winds from the N. That’s a nice window for a more experienced surfer.

Overall, the best two sessions are looking like Monday morning, August 3rd, for the first bigger pulse of clean groundswell around 7ft, and then Sunday morning, August 9th, for the cleaner, more manageable 5ft swell. The mid-week monster swell is for the hardcore crew only.
