Onjuku Surf Forecast and Surf Report

Alright folks, grab a coffee. For the next couple of weeks, Onjuku is playing a bit of a waiting game. The good news is, there’s some proper swell moving in later on, but the wind’s gonna be the main character for a while—and not in a good way. Water temp is sitting around 82°, which is a touch warmer than normal for this time of year.

Wednesday 26th – Forget about it today. We’ve got a swell at 3 ft from the SSE, but that cross-onshore SW wind at 18 mph has got it all lumpy and messy. Combined energy is moderate (410), but the quality is just poor.

Thursday 27th – A mixed bag. Morning is a write-off with stormy vibes and a choppy 4 ft SW swell. But look... Thursday afternoon has a glimmer. That tiny 2 ft E swell has a proper long period (13 seconds) and the wind swings light WNW, going cross-off. It’s going to be clean. Shame about the size, but for a sneaky session, that’s your best bet on this day.

Friday 28th – Rough morning with light onshore wind and a questionable tide. Afternoon builds to 4 ft from the SW, but with a junky 6-second period and cross-on wind, it’s a no-go. Leave it.

Saturday 29th through Monday 31st – A long, quiet stretch. We’re looking at tiny waves, mostly under 2 ft, and weak energy readings in the double digits (87 to 171). The wind is mostly cross-off, keeping it clean, but there’s simply no power. Perfect for a float, not for a surf.

Tuesday 1st September – Now we’re cooking. This is the first standout of the whole forecast. The morning brings a 3 ft S swell with a solid 12-second period, and the energy jumps to a strong 514. Wind is NE at 12 mph, cross-off, so it’s gonna be clean. The waves will have some proper shape. This is a real chance for some fun, lined-up waves.

Wednesday 2nd September – Building to 4 ft from the S, but the wind turns cross-onshore from the SSE at 15 mph, and the rain showers ruin the party. The energy is there (658), but the wind chops it up.

Thursday 3rd September – Swell hits 6 ft from the S, combined energy at 962. This is a proper pulse. But the wind is howling onshore at 18 mph, making it bumpy and messy. Too big and too windy for a pleasant paddle. If you’re a kite surfer, this might look interesting.

Friday 4th through Sunday 7th – A big drop-off. Swell stays around 3 ft to 4 ft, but the wind is consistently onshore or cross-onshore, and the energy drops back to the low hundreds to mid-400s. The quality is poor across the board. A total write-off.

Monday 8th September – This is the best session of the whole 16-day window. Mark it in your calendars. We’ve got a 5 ft SSE groundswell, and the period is a lovely 12 seconds. That’s proper. The wind in the morning is a light NE cross-off, and in the afternoon it goes glassy at 3 mph from the ESE. Combined energy is 631 and 594. The waves will be clean, groomed, and have some push. Onjuku is exposed to this SSE swell, so it’ll pick it up nicely. Expect some good lines, but be aware it might get a little busy—crowds are sometimes a thing here.

Tuesday 9th September – Still very decent. A 4 ft S swell with 12-second period, and you’ve got another glassy afternoon with 3 mph wind from the east. Combined energy is strong (541 to 633). The morning has a light cross-on breeze, but it’s manageable. A solid follow-up day.

Wednesday 10th September – And then we’re done. Swell direction swings SSW, period goes to 13 seconds, but the wind cranks up to 18 mph from the SW, cross-on. The energy is high (668-749), but the surf will be lumpy and tough to enjoy.

So to wrap it up: Monday 8th September is your absolute standout, with Tuesday 1st September being a close second for cleaner, smaller waves. The rest is wind-affected or flat. Get out there on those days.

Rusty.
