Onjuku Surf Forecast and Surf Report

Alright, Rusty here, let’s talk about what’s on the cards for Onjuku.

Right now, we’re looking at a stretch that has some promise but also a lot of size that will shut things down. The first decent session kicks off on Sunday morning, August 2nd. It’s not going to be a classic, but it’s the best we’ve got to start with. The water temp is sitting at 80°F, which is about average for this time of year, so no need for a thick suit.

We’ve got some groundswell from the SSE rolling in, about 4ft with a long 16-second period. The combined energy is moderate (703). The wind is a light cross-off from the NE at 9 mph, so it’ll be clean. It’s inconsistent here, and the crowds can be an issue sometimes if people sniff it out. Still, for a Sunday morning, that’s the one to paddle out for.

Monday looks bigger but rougher. By Monday afternoon the swell is up to 8ft from the SE with a 17-second pulse, and the energy jumps to 3386, but the wind is up to 22 mph cross-off. It’s not going to be clean enough to make it fun. Tuesday and Wednesday see the swell really jack up, hitting 10ft to 13ft. The wind stays cross-off but at 22 mph, and the energy readings are massive—over 4600 and up to 9706. That’s serious grunt, but honestly, it’s too big for this break. That kind of size is for experts only, and even then, it’s gonna be a handful. The setup here might start looking more interesting for kite surfing than paddle surfing on those days.

Thursday the 6th keeps the swell huge at 12ft to 13ft, but the wind swings more onshore or cross, and we’re looking at storm risks and choppy conditions. Not good.

We then get a bit of a drop-off. Friday the 7th has a 8ft swell from the S with a 15-second period, and moderate cross-off wind, so it’s clean but not great. Saturday the 8th is a write-off with cross-onshore wind and storm risks. The best of the second batch comes Sunday the 9th and Monday the 10th. Sunday morning has clean 5ft swell from the SSW (2012 energy), and light cross-off wind. Monday morning is similar, with 6ft from the ESE (1470 energy) but the wind is picking up to 22 mph again.

After that, from Tuesday the 11th onward, we’re into a long run of marginal to poor conditions. The swell stays consistent but the wind is howling—25 mph offshore or cross-off, and the energy readings dip and spike. It’s just not going to come together for a quality paddle. The 14th and 15th of August are particularly rough with strong cross-winds and poor conditions.

So to sum it up: Sunday the 2nd is the standout—clean, moderate energy, and the best wind of the whole outlook. After that, it’s a waiting game with a lot of blown-out or oversized days. Stick to that Sunday morning session.

Rusty.
