Onjuku Surf Forecast and Surf Report

Alright, let me break this down for you, Onjuku style. The first week is a bit of a dud, so don’t rush down there right away.

From Wednesday the 29th through the weekend, we’re looking at weak, gutless swell. Wednesday morning has a 5ft SW swell, but it’s only 7 seconds apart and the wind is cross-onshore, so it’s messy. The energy is weak (343). Thursday morning the 30th cleans up with a light offshore from the NNE, but the swell drops to 2ft, so it’s tiny and forgettable. Friday and Saturday are the same story – small, short-period waves and nothing with any push.

Sunday morning, the 2nd of August, is where it gets interesting. The swell jumps to 4ft from the SE, and the period goes to 15 seconds – that’s real groundswell. The energy is strong at 607, and the wind is light and variable, so it could be glassy. The tide might be a factor, but it’s the best looking surf all week. Water temp is 81°, right on average for the season.

Now, the main event: Monday the 3rd of August. The swell hits 8ft from the SE with an 18-second period, and the energy is massive at 3802. The wind is a clean cross-off from the NNE. That’s big, clean, and powerful. But by Tuesday the 4th, it really blows up: 13ft to 15ft from the SE, with energy over 8000 to 10000. The wind stays clean, but this is way too big for most guys. Only the experts should even be thinking about it. The wave comment says it’s too big for this break, and I’m telling you, it’s into serious big-wave territory.

Wednesday the 5th peaks with 18ft swell and energy over 17000. Absolutely massive, but it’s beyond what Onjuku can handle for a normal session. Crowds are sometimes a thing here, but on these days, you’ll only see a handful of chargers.

Into the second week, the swell drops but stays solid. Thursday the 6th still has 8ft from the SSE, but the wind turns onshore and choppy, so the quality takes a hit. From the 7th onward, it’s smaller, weaker swells with onshore winds, and the energy drops under 1000. The cleanest window comes around the 13th of August, with a 4ft E swell and a gentle offshore from the N, giving you clean, fun waves – nothing big, but a good session.

The standout is Sunday the 2nd of August: that 4ft SE groundswell with light wind and a long period. It’s the most user-friendly, cleanest surf in the whole run. For the real heavy hitters, Monday the 3rd through Wednesday the 5th is the big-wave window, but only if you’re ready for it.
