Onjuku Surf Forecast and Surf Report

G’day, Rusty here, lookin’ at the Onjuku forecast for the next couple of weeks. The water’s sittin’ at a warm 80°, which is pretty much spot on for this time of year, so no surprises there.

The first few days are pretty quiet. Friday the 31st has a tiny 2ft swell from the SSW, with a short 6-second period and weak energy (84). It’s surfable, but very ordinary. Saturday the 1st drops off even more with a 1ft SE swell, though the morning is glassy – that’s a lovely look, but the size just isn’t there. Then on Sunday the 2nd, we finally get a pulse. A 4ft SE groundswell (16 sec) rolls in, with the combined energy jumping to 622 (moderate), and a clean cross-off wind from the ENE. That’s the standout for the first week. The swell builds through the day to 4ft, still clean, but the wind picks up to 15 mph, making it a bit lumpy. That Sunday morning window is the one to target – it’s not huge, but the conditions are right.

Monday the 3rd pushes into bigger territory with a 7ft SE swell and a long 16-second period, energy ripping at 2404 (strong). The wind is cross-off but at 15 mph, so it’s clean but chunky. By Tuesday the 4th, the swell hits 12ft, and the energy is massive (6680, very strong). That’s too big for this break – it’s only for experts. The whole week from the 4th to the 7th is pumping with 12ft to 15ft swell, but it’s just too much for Onjuku. The wind turns cross-shore and onshore, making it messy. If you’re a kite surfer, the 4th and 5th look interesting, but for paddle surfing, it’s a pass.

After the big stuff, Sunday the 9th rolls in with a 5ft ESE swell and a 13-second period, energy 1095 (moderate). The morning is clean with a cross-off breeze from the ENE at 9 mph. That’s the best call for the second week – solid, clean, and manageable. The following days, Monday the 10th through to the 14th, hold around 5ft to 6ft, but the wind gets strong, especially on the 11th and 12th with 25 mph offshore winds. That’s clean but a real fight to paddle into. Then Saturday the 15th, the energy drops to 501 (weak), with a 4ft E swell and a light cross-off – it’s surfable, but nothing special.

There are a few gaps: from Friday the 31st to Saturday the 1st, there’s really nothing worth paddling out for. And from the 4th to the 8th, it’s either too big or too messy. The standout sessions are Sunday the 2nd morning and Sunday the 9th morning. The 9th is the best of the lot overall – clean, moderate swell, and a long period that’ll give some nice lines at Onjuku, especially since it’s a beach break and that long period can make it a bit straight, but with the cross-off, it should be fine. Crowds are possible here, so get in early.

Rusty.
