The Lowdown

Alright folks, Rusty here. Let’s break down the forecast for Off The Wall. We’ve got a solid run of swell coming, but you’ll need to be picky about the wind.

The main story is a long period SW groundswell that builds in and pulses through the next week and a half. The energy is strong, with readings hitting 3580 at the start. That’s serious power. The water is sitting at 55° which is a full 5° colder than usual for this time of year, so you’ll want a thicker suit and maybe booties.

The standout session is Saturday morning, August 15th. The wind goes glassy from the SSE at just 3 mph, and we’ve got a clean 6 ft swell from the WSW with a period of 13 seconds. It’s a reef break, so that long period will wrap in beautifully. The conditions are excellent for experienced surfers, and with the glassy surface, it’s going to be butter smooth. Crowds are possible here, but on a Saturday morning with that quality, expect a few locals out.

The next real highlight is Monday morning, August 17th. The swell bumps up to 8 ft from the WSW, again with a 13-second period, and the wind is glassy from the SSE. That’s a solid, powerful wave. It’s heading into the bigger range, so this is one for the experienced crew only. The combined energy is 2187, so plenty of grunt.

Looking further out, Saturday, August 22nd is a promising long-range call. The swell jumps to 10 ft from the SW with a 16-second period, and the wind is offshore from the SSE at 16 mph. The combined energy is 3953, which is huge. This is a serious groundswell. It’s a little less certain this far out, but if it lines up, that’s a day for experts only. The 16-second period will make the sets long and powerful, perfect for a reef like this.

Between the good days, there are some average sessions. The winds turn onshore and choppy through the 14th, the 16th, and the 18th. The swell stays around 6 ft to 7 ft, but the texture is messy. Not worth the paddle.

From the 20th onwards, the swell drops right off into the 4 ft range, and the wind is mostly offshore, but the wave size is small. There’s a solid pulse again on the 22nd and 23rd, but after that, the end of the window sees the swell fade to under 3 ft and the wind turns onshore again. The 27th and 28th bring some cross-onshore wind and choppy conditions with 6 ft swell, but it’s not clean.

So, bottom line: Saturday the 15th and Monday the 17th are your best bets for clean, quality waves. The 22nd is a long-range standout if you’re keen on a big swell chase. Otherwise, pick your windows and don’t be afraid to sit out the choppy days.

Rusty.
