Onjuku Surf Forecast and Surf Report

Alright, let’s talk about what’s coming up for Onjuku.

Honestly, mate, the next week and a half is gonna test your patience. There’s a real long quiet stretch here. We’ve got nothing worth paddling out for from the start all the way through to the morning of Tuesday, 29 July. That’s over two weeks of waiting. The wind is mostly onshore or cross-onshore, and the swell is tiny and weak. The energy is barely registering most days—often under 200 (weak to moderate energy). It’s pretty frustrating.

The one and only standout in this whole 16-day window is the morning of Tuesday, 29 July. That’s your best bet by a long shot. Onjuku picks up a solid groundswell from the SE. Swell height hits 4 feet, with a very long period of 13 seconds. That long period means the waves will have real shape and push, but because it’s a beach break, it might run a bit straight. The energy is strong—560 (very strong wave energy). And the wind goes glassy, light from the NE. That’s gonna make for clean, lined-up sets. For an intermediate surfer, this is the session to aim for. Crowds can be "sometimes" an issue here, so expect company.

The afternoon of the 29th drops off quickly as the wind turns onshore, so get it early.

Water temp is 77°, which is about average for the time of year, so not a worry.

Before that? Honestly, nothing. The swell stays small—under 3 feet—and the wind is almost always messy. Short period swells too, mostly around 8 to 9 seconds, so no grunt. A few mornings like Sunday 20th and Tuesday 21st have glassy or clean conditions, but the waves are barely there and the energy is weak (under 180). Not worth getting excited over.

The second half of the month is a blank run. This isn’t unusual for the area when the wind patterns lock in bad. But once that SE groundswell and glassy morning line up on the 29th, it’s a proper reward for the wait.
