The Lowdown
G’day, Rusty here. Let’s have a look at what’s on offer at Off The Wall. This spot’s a proper reef, exposed to the open ocean, so it needs a decent swell to get moving. The water’s sitting at about 56°, which is a solid 5° colder than it should be this time of year – that’s properly cold, so you’ll want the thickest wetsuit you’ve got.
We’ve got a run of surf coming in over the next couple of days, but it’s not all clean. Kicking off on Tuesday morning, there’s a solid 10ft SW swell with a 13-second period, and the energy reading is strong at 2639. Conditions are clean with a light cross-off breeze. This is great, powerful surf, but at this size (10ft), it’s strictly for the advanced crew. The afternoon stays similar, energy jumps up to 3415, but the tide gets a bit questionable.
Wednesday looks like a repeat – another 10ft SW swell and clean conditions in the morning, energy at 3299. This is the standout morning of the first few days. The swell’s the same, but the conditions are a touch better rated. Expert-only again. The afternoon goes a bit marginal.
Thursday morning, the swell drops to 6ft from the WSW, with a 13-second period. It’s glassy – absolutely clean – and this will be the best wave-to-crowd ratio of the early window. Still a solid size, and the light airs will have it looking perfect. But then the wind swings SE and goes nuts, hitting 31 mph by the afternoon. The swell bumps back to 10ft but the period drops to 9 seconds, and it’s blowing a near gale offshore. That’s a battle, not a surf.
The next couple of days are a write-off. Friday’s got 28 mph SE winds and dropping swell. Saturday is cleaner but smaller. By Sunday, we’re down to 5ft but the period jumps back to 16 seconds – that’s a proper long-period groundswell, though it might be a bit straight for a beach break. For an exposed reef like this, it should be firing. Light winds, so a fun, mellow day.
Monday the 7th is small, around 4ft, but clean and glassy. Nothing special. Then we hit a lull. Tuesday the 8th and Wednesday the 9th see the swell die right down to under 3ft. A few days with nothing doing – you’ll be watching the horizon. Don’t bother.
Things pick up again on Thursday the 10th, with 5ft of WSW swell and clean conditions in the morning, but the wind gets up in the arvo. The real gem of the second week looks like Friday the 11th. We get a 6ft WSW swell with a 15-second period, and a moderate offshore breeze holding it clean all day. Energy’s strong at 1684. This is the standout of the whole period – good size, clean, and proper power.
The following days are more of the same, with offshore winds and moderate swells, but nothing that will have you cancelling plans.
Now, go a bit further out. On Wednesday the 16th, there’s an interesting shift. The morning is small and messy, but the afternoon is something else. The swell bumps up to 8ft from the SW with a massive 16-second period. The energy reading is huge at 4106, and it’s glassy. This looks like it could be the biggest, cleanest swell of the entire outlook, but it’s also 10 days away, so take it with a grain of salt. At that size, it’s expert-only, and if it lines up, it’ll be a day to remember.
For your best bets, Thursday morning looks great for a slightly less hectic session. But for the biggest, cleanest, most powerful waves, Friday the 11th is the pick of the near-term. And watch that Wednesday the 16th forecast – it could be a monster.
Rusty out.

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. If you surf the same spot (Off The Wall) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
