Onjuku Surf Forecast and Surf Report

Alright, Rusty here. Let’s have a look at what’s cookin’ for Onjuku.

First thing I gotta say is, the water’s sittin’ at 78°, which is pretty much where it should be for this time of year – no real surprises there, just a nice warm bath to paddle around in.

The outlook starts off with a bit of a slow burner, but there’s a real standout day that’s got my blood pumping. We’ve got a solid building trend through the first week, with the best of it looking like Tuesday the 11th of August. That morning, the swell is a proper 10 ft from the ENE, with a period of 11 seconds – that’s a good, punchy groundswell with some decent energy behind it (2529). And the wind? Glassy, offshore, light breeze. That’s the kind of combo that’ll have you shaking on the beach. That afternoon keeps the 10 ft ENE swell going, with a 10-second period (2128) and clean, light offshore wind. This is big, powerful surf – over 8 ft, so this is strictly for experienced surfers. Beginners, stay on the sand and watch.

Before that, we’ve got some fun building swell on Thursday the 6th. Morning session has a 7 ft SSE swell at 13 seconds – that’s a long-period groundswell with a lot of push (1955) and clean cross-offshore wind from the ENE. It’s got that excellent surf feel for those who can handle a bit of size. The afternoon gets a bit more cross-on, so the window’s tighter.

Thursday morning is solid, but that Tuesday is the real gem. The following Sunday the 9th also looks promising with a clean 6 ft from the ESE and cross-off wind, a good option if you miss the peak.

After that Tuesday standout, the swell drops but stays rideable through to about the 17th, with clean conditions and cross-off winds holding in. The energy dips into the moderate range (under 1000) by then, but there’s still something to get wet for. From around the 19th, things get pretty weak and the wind picks up – a lot of fresh breeze and poor surf. That’s when you might wanna hang the wetsuit up for a few days. There’s a little bump of 4 ft from the S on the 21st, but it’s nothing to write home about.

Overall, the first week has the best windows, with Tuesday the 11th being the absolute standout. Get it while it’s good.

Rusty.
