The Lowdown
Alright folks, Rusty here. Let’s break down what’s coming for Off The Wall.
We’ve got a solid run of swell, but the first few days are a bit mixed with cross-onshore winds making things choppy. The water is running at 56° and that’s about 4° colder than usual for this time of year, so you’ll want a thicker wetsuit if you’re spending a lot of time in the water.
The real standout is Saturday, August 30th. That morning is looking absolutely world-class. You’ve got a 13ft swell from the southwest, rolling in with a 16-second period and glassy conditions. The combined energy is a massive 8326, so that’s deep, powerful groundswell. This is serious, expert-level stuff. The reef will handle it beautifully, but it’s not for beginners.
Leading up to that, there are some good windows. Wednesday, August 21st, is a great call. The morning has glassy conditions with a clean 7ft southwest swell and 11-second period. The energy is 1147, so it’s got some push but it’s manageable. The crowds are sometimes a factor here, but for a morning like that, it’ll be worth it.
The other big one is Monday, August 26th. That morning is glassy again, with an 8ft southwest swell running at 16 seconds. The energy is 3435, and it’s clean. Another top-shelf day for experienced surfers.
The first week has some solid 8ft days, but the wind is often cross-off or onshore, so the quality isn’t as pristine. Tuesday, August 20th, sees a 10ft southwest swell in the afternoon, but it’s a bit choppy with a moderate breeze. Still, it’s surfable for the crew with some skill.
Avoid the mornings of August 22nd and 28th – the wind is straight onshore, and the conditions are poor. The combined energy is low, around 850 to 1047, and it’s just not worth the paddle out.
From August 24th through the 26th, we’ve got a consistent run of clean, solid swell. The morning of the 24th has an 12ft SSW swell at 15 seconds and 4852 energy – that’s a proper groundswell. It’s clean, but it’s big, so only for the experienced.
The last day of the month, August 31st, still has a good 10ft southwest swell with offshore winds and a light breeze. Classic post-storm cleanup.
All in all, the best on offer is the morning of August 30th – that’s the one to set your alarm for. The 26th is a close second. The rest of the period has plenty of action, but you’ll have to pick your windows with the wind.
Rusty.

Information about the Off The Wall Surf forecast
The above surf forecast table for Off The Wall provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Off The Wall can be found by selecting the local surf guide option on the grey menu.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Off The Wall may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
