The Lowdown
Alright, this is Rusty checking in. Let’s have a proper look at what’s cooking for the next couple of weeks.
First thing you gotta know, the water’s running at 55° right now, which is a solid 5° colder than usual for this time of year. That’s a notable chill, so don’t even think about ditching the wetsuit.
We’ve got a bit of a slow start here. The first real action worth paddling out for is Off The Wall on Saturday, the 5th of September. Saturday morning, we’re looking at a clean 7 ft swell out of the SSE, with a moderate offshore wind from the SE at 12 mph. It’s clean, it’s surfable. But the afternoon is where it steps up – 8 ft from the same direction, still offshore, and the wave energy jumps into the moderate range (1048). This is good stuff for experienced surfers.
Then, Sunday the 6th of September is a proper standout. The morning session is the best on offer in this whole run. We’ve got a 8 ft swell shifting around from the SW, light offshore wind from the SE at only 6 mph, and the period hits a very long 18 seconds. That’s a classic groundswell. The combined energy is a thumping 3892 – strong. This is prime for a reef like Off The Wall. The long period will push through clean, with good shape and long gaps between sets. It’s an expert’s wave, no doubt.
After that, things get a bit messy and inconsistent through the middle of the week. Monday the 7th sees onshore winds that kill the quality. Tuesday the 8th has a glassy morning with only 4 ft on offer – small but clean for a sneaky session.
We get another pulse on Thursday the 10th of September. Morning shows 8 ft from the SW with a 14-second period and light winds. The energy is high (2276). It’s solid, but the afternoon picks up a cross-offshore breeze that keeps it clean enough for the experienced crew.
From there, it’s a mixed bag. The 12th of September throws up a 10 ft SW swell with strong offshore winds at 25-31 mph, but that’s near-gale territory – incredibly hard to paddle into, even for experts. The energy is massive (4191), but the wind is a battle.
The real eye-opener is a long way out. On Friday the 18th of September, we’ve got a massive 15 ft SW groundswell rolling in with a 14-second period. The wind is a light cross-shore at only 3 mph, and the wave energy hits a huge 6765. That is a serious, serious swell. It looks more like a day for tow-in or a heavily experienced crew only. The conditions are clean overall, but that size is not for the faint of heart.
To sum it up: Sunday morning, the 6th of September is your standout. Long-period SW groundswell, clean offshore breeze, strong energy – that’s the one to circle. The Saturday the 18th of September is the wildcard for experts, but it’s far out and things can change.
Stay sharp, keep an eye on the forecasts, and don’t be a hero in the big stuff if you’re not ready.
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. 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.
