The Lowdown
Alright, Rusty here. Let's cut through the numbers.
We’ve got a solid run of swell coming for Off The Wall, but the first few days are a bit of a lottery. Tuesday and Wednesday the 21st and 22nd have the swell, but the wind is a problem. Tuesday morning is glassy with a 2.4m SW swell, but that’s a big one for the reef, so it’s strictly for the advanced crew. The energy is there with a combined energy of 2375. By Wednesday, onshore breezes are going to mess it up.
Thursday the 23rd is a total washout. Strong, bumpy wind and a building swell. No good. Friday the 24th is the one to circle. That morning is exceptional. We’re looking at a 3.5m SW groundswell with a 15-second period, clean offshore wind from the SSE, and a massive combined energy of 5020. That’s not for beginners – this is expert-only territory. The water temp is about normal for this time of year.
Saturday the 25th through Sunday the 26th keep the fun rolling. The swell drops to a more friendly 2.0m to 2.2m, with clean cross-off winds and energy still in the thousand-plus range. Solid for experienced surfers.
The next week is a mixed bag. Monday the 27th is small but clean, with a 1.2m swell and a 16-second period. Tuesday the 28th brings strong offshore wind – clean, but those 40 km/h gusts will make paddling a real workout. Wednesday the 29th through Friday the 31st is a beautiful run of glassy mornings and clean afternoons, with swell around 2.1m to 2.3m from the SW. The energy stays strong, and the conditions are just right.
The real gem is Saturday the 1st of August. The morning is dead calm, glassy, with a 2.4m WSW groundswell at 16 seconds and a combined energy of 2794. That’s a long-distance, powerful swell hitting a reef. That’s a classic. After that, the swell starts to fade a bit, but there are still clean windows.
The best of the best is Friday the 24th morning for the experts, and Saturday the 1st of August glass-off for anyone who can handle a reef. Expect crowds at Off The Wall – it’s a popular spot for good reason.
Rusty.

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.
