Onjuku Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s look at what we’ve got for the area.

Right now, things are looking pretty flat. We’ve got a few days of small, junky stuff at Onjuku, but honestly, there’s nothing worth paddling out for from Monday the 31st of August through to Saturday the 6th of September. The surf is tiny, wind is cross-off, and the energy is just not there. We’re looking at weak, short-period waves with combined energy values mostly between 100 and 272 – that's just not enough to get excited about. You’ll be waiting around for nothing.

The first real standout comes on Monday the 7th of September. This is the morning to circle on the calendar. Onjuku wakes up to a clean 7 ft swell from the ESE, period around 9 seconds. The wind is light offshore from the NNE in the morning, going glassy in the afternoon. The combined energy jumps to 747, finally some proper push! The water temperature is about average for the time of year, nothing weird there. This is the best on offer. Conditions look very good, with nice, clean lines. Confident call for this one.

Tuesday the 8th keeps the party going with a 6 ft SE swell in the morning and more clean conditions. The energy is strong at 1166, so expect some decent grunt. This is a solid follow-up day for experienced surfers. The wind stays clean, though it picks up to a cross-off by the afternoon.

We then hit a messy patch. Wednesday the 9th still has some size, around 6 ft from the SE with a long 12-second period and strong energy (1136), but the wind gets stiff and cross-off, making it less appealing. From Thursday the 10th through Saturday the 12th, things get stormy and ugly. Strong cross-onshore winds, risk of thunderstorms, and the swell turns to junk. By Saturday morning, the swell is 10 ft from the SSE, but it’s blown out with fresh cross-onshore winds and lumpy conditions. That’s expert-only, if even surfable, and it looks more interesting for kite surfing than paddle surfing.

Sunday the 13th is still poor. Monday the 14th shows a bit of life with a 6 ft SE swell and light cross-onshore breeze, but it’s marginal. The combined energy is moderate, but the wind is not ideal.

Now, for the long-range promise – Tuesday the 15th of September. This is a very promising, but less certain, call. The models are showing a massive 16 ft swell from the SSE with a long 13-second period, and the combined energy is a whopping 8984. However, the note says the swell is predicted to be too big for Onjuku. The wind is cross-off from the NE, so the conditions would be clean, but this is only for the most experienced big-wave chargers. If it comes in, it’ll be a spectacle, but don’t get your hopes up until it’s closer.

Overall, the week starts slow, but the 7th and 8th of September are your true standouts. After that, it’s a mixed bag of big but messy surf, with a wildcard at the very end.

Rusty out.
