The Lowdown
Alright folks, Rusty here. Let’s talk about what’s cooking at Off The Wall. This is a reef break that needs a bit of respect – it’s an advanced wave, and it’s fairly consistent, so it doesn’t stay flat for long. The water is sitting at 55.6°, which is a solid 4° colder than usual for this time of year, so you’ll want a thicker wetsuit. The swell energy is moderate to strong, with readings climbing into the thousands (1184) for the first session, which is a good sign.
The best of the bunch kicks off on Tuesday, August 11th afternoon. We’ve got a clean 4.6 ft SSW swell with a 12-second period, light offshore SE wind at 10 km/h, and it’s an exposed reef that loves a SW swell direction. The water may be cold, but the surf is excellent for experienced surfers – the energy is there (1184), and the conditions are crisp. If you can only pick one session early on, this is it.
Wednesday, August 12th is a standout. The morning sees a 6.2 ft SW groundswell (18-second period!) with a cross-off E breeze at 10 km/h. That’s a long-period, powerful swell – the kind that wraps into reefs beautifully but can be a handful. The energy is massive (2379). The afternoon is even cleaner: glassy conditions with an ESE offshore breeze at 5 km/h, same solid 6.2 ft SW swell (17-second period). This is the best day of the run, no question. Get on it.
Thursday, August 13th morning is a bit messier. The swell is up to 7.9 ft from the SW, but a cross-shore NE wind at 15 km/h puts a little chop on it. The energy is pumping (3487), but it’s solid for experts only. The afternoon though? Glassy. WNW wind at 5 km/h, 7.2 ft SW swell, 16-second period – clean and powerful. That’s a great session if you’re comfortable with size.
Friday, August 14th is a write-off. The wind shifts onshore from the N and NNW at 15 km/h, making it choppy with 5.9-5.6 ft WSW swell. Energy drops (1409-1281). Not worth paddling out.
Saturday, August 15th is a redemption. The morning is glassy (NNE 5 km/h), 5.9 ft WSW swell, 14-second period – clean and fun. The afternoon lights up with a cross-off SSW breeze at 10 km/h, same 5.9 ft swell, just a slightly shorter period (13 seconds). Energy is still decent (1166-1201). This is a solid weekend session.
Sunday, August 16th morning is onshore and choppy again (NNW 15 km/h), 5.6 ft WSW swell – skip it. But the afternoon is a glassy dream: NW wind at 5 km/h, 6.9 ft WSW swell, 14-second period, energy shooting up to 1728. That’s a beauty for the late session.
Monday, August 17th is a mixed bag. The morning has a light cross-onshore N wind at 10 km/h, 7.9 ft WSW swell – it’s big and a bit bumpy. The afternoon goes onshore NNW at 15 km/h, 7.2 ft. Not great for quality surfing.
Tuesday, August 18th brings a bit of light rain in the morning, but a cross-off SSW wind at 15 km/h keeps it clean. Swell is 5.6 ft WSW, 12-second period, energy dropping to 849. It’s good

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. Our Off The Wall surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period.

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.
