The Lowdown
Hey folks, Rusty here. Let’s talk about what’s cookin’ at Off The Wall. This is a proper reef break for advanced crew only, and it’s exposed to the SW swell window, which is exactly what’s gonna light it up over the next couple of weeks.
Right now, the water is a pretty chilly 53°, which is a solid 7° colder than usual for this time of year – that’s a big anomaly, so don’t be shy with the thick wetsuit. The first few days are a bit of a slow burn. Tuesday morning, September 8th, we’ve got a weak 3ft WSW swell at 12 seconds, but the wind is a light cross-onshore, so it’s a bit messy with only 523 units of wave energy. Tuesday afternoon drops to 2ft, and Wednesday is similar with small 3ft to 3ft WSW swell. It’s clean in the afternoons with a light cross-offshore breeze, but honestly, it’s not really doing much. We’re waiting.
Then Thursday, September 10th, the place wakes up. The morning brings a solid 8ft WSW groundswell at 14 seconds, with a gentle cross-offshore breeze and a massive 2346 units of energy. This is excellent for experienced surfers – long period, clean lines, proper reef setups. That’s a standout right there. The afternoon stays solid at 7ft, though the wind picks up a bit. Friday morning, September 11th, keeps the love going with a 6ft WSW swell at 12 seconds, true offshore wind from the SE, and 1166 units of energy. It’s clean and lined up. The afternoon gets a bit messy with a short-period 8ft SSE windswell at only 7 seconds – that’s one for the experts only.
Saturday, September 12th, is another big one. Morning has 6ft SW swell at 14 seconds with offshore wind and 2240 units of energy. The afternoon pumps up to 6ft SW with a 16-second period, a fresh offshore breeze, and a ripping 3531 units of energy. That’s the kind of energy that makes this reef sing. Sunday, September 13th, holds onto 6ft to 6ft SW swell, with a glassy afternoon on the 13th. The Monday and Tuesday after that get blown out by strong onshore winds, so we’re looking at a write-off.
Now, the real fireworks start on Wednesday, September 16th. The morning delivers a 12ft WSW groundswell at 15 seconds, with offshore wind and a huge 5713 units of energy. That’s exceptional, expert-only territory. The afternoon stays big at 12ft. Thursday, September 17th, drops to 6ft but the wind is a screaming 28 mph offshore – strong and clean, but it’ll be a battle to paddle into. Friday, September 18th, is a beauty: 8ft SW swell at 14 seconds, light offshore breeze, and 2557 units of energy. Cruisy and powerful.
Saturday, September 19th, is glassy in the morning with 6ft SW swell – that’s a dream session if you can get it. Sunday, September 20th, gets a massive 13ft WSW swell, but it’s a bit cross-onshore, so it’ll be lumpy. That’s for the hardened locals only. The following week, starting Monday, September 21st, settles into a solid run of 6ft to 8ft SW swell with clean cross-offshore winds. Wednesday, September 23rd, finishes the run with a 15ft SSW groundswell at 17 seconds and a staggering 10801 units of energy. That’s a monster, but it’s marginal due to the size – only the top dogs will be out.
Overall, the standout windows are Thursday morning, September 10th, for the first big push, and Wednesday morning, September 16th, for the pure power. Keep an eye on Saturday, September 19th, for that glassy session. Crowds are possible at Off The Wall – it’s a known spot, so expect some company on the peak days.
This is Rusty, signing off.

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.
