Onjuku Surf Forecast and Surf Report

Alright, Rusty here. Let's get into it.

Right off the bat, we're looking at a pretty quiet and sloppy run for Onjuku for the next week or so. The first real standout is a long way off, so we've got a bit of a wait on our hands.

The water is sitting at 81°, which is pretty much what you'd expect for this time of year, so no drama there.

The first few days are a real write-off. Monday the 17th through to the weekend has tiny, weak swell (around 1ft to 3ft) with a mix of cross and onshore winds. The wave energy is low, between 88 and 315 points, so it's a flat, choppy mess. Not worth paddling out for.

Things turn a bit more interesting, but still not good, starting Monday the 24th. A big pulse of short-period swell arrives, but it's all windswell with onshore gales. The energy jumps up to 662 (moderate to strong), but the wind is howling onshore at 25 mph, so it's a washing machine scenario. It's going to be way too messy for a surfboard, but honestly, this setup would be more interesting for kite surfing than paddle surfing.

The real standout comes through on Wednesday the 26th of August. We've got a solid 8ft to 8ft SSE groundswell with a very long 16-second period. The wave energy is absolutely pumping, hitting 3229 to 3867 points. The wind is light and offshore from the east, so the morning in particular is going to be glassy and clean. This is proper groundswell, so while it'll have plenty of power, that long period can make it break a bit straight at the beach. Keep that in mind. The size is getting up there, so it's more for experienced surfers.

Thursday the 27th is even bigger, with 10ft to 12ft of SSE swell, but the wind picks up to a fresh breeze. The energy is massive (over 4800), but it's getting into the "too big" zone for this spot. It's a clean, offshore wind, but the swell size is only for the experts.

The tail end of the period, around the 31st of August and 1st of September, sees the swell start to drop back. The wind finally turns clean and offshore, so you'll get some clean, fun-sized waves in the 6ft to 8ft range. It's not the big, powerful groundswell of the 26th, but it'll be a much more user-friendly option.

So, if you're looking for the best of the bunch, mark your calendar for Wednesday the 26th of August. That morning at Onjuku is the one to target: clean, offshore, and a solid, long-period swell. The rest of the period is either flat, blown out, or too big.
