The Lowdown
Alright folks, Rusty here. Let’s get into what’s shaping up for Off The Wall. This is a reef setup, exposed to the swell, and it packs a punch for advanced surfers only.
Right off the bat, Saturday morning the 15th is looking like a solid call. We’ve got a clean 5.6ft swell pushing in from the WSW, period around 14 seconds – that’s a nice groundswell with good energy (1120). The wind is dead calm, glassy. Water temp is sitting at 55.2°, which is a whopping 4.9° colder than normal for this time of year. That’s a major chill, so make sure you’ve got the thick rubber. Crowds are sometimes an issue here, but early, with those conditions, it’s worth fighting for a wave.
Saturday afternoon picks up a touch, 6.6ft, still clean with a slight cross-off breeze. Still very good.
Sunday the 16th, the wind swings northerly and gets on it. The swell stays solid but the surface gets chopped up. It’s a write-off for quality.
Monday the 17th morning is messy, but Monday afternoon it cleans right up again. 7.9ft, cross-off breeze, and plenty of power (2299). A good afternoon session for the crew who can handle it.
Tuesday the 18th is a standout. Morning has a clean 5.9ft with a solid offshore wind from the SSE (12 mph). It’s clean, groomed, and the swell is packing good energy (1715). Afternoon bumps up to 8.2ft, still clean with a cross-off. This is a full day of quality.
Wednesday the 19th through Thursday the 20th keep that clean theme going with moderate offshore winds, swell hanging around the 6.9ft to 7.5ft mark. Solid, consistent conditions.
Friday the 21st morning is another beauty to highlight. Glassy conditions, 5.9ft of SW swell, period dropping to 11 seconds. Energy is down a bit (794), but for a clean, user-friendly session, it’s a gem. Afternoon gets a bit wind-affected.
Saturday the 22nd is a write-off. Big, messy, and blown out with a 13.1ft to 14.8ft swell and strong cross-onshore winds. Kite surfers might be eyeing this up, but for paddle surfing, forget it.
Sunday the 23rd gets interesting. Huge swell, 13.1ft, but with a fresh offshore wind from the SSE. It’s big, powerful, and for experts only – the period is 13 seconds, and the energy is massive (8162). This is a big-wave day. Afternoon sees a slight drop but still heavy.
Monday the 24th is the true standout of the whole window. Morning has 9.8ft of clean groundswell from the S, 14-second period, light offshore wind. Energy is pumping (5670). Afternoon is even better, 9.8ft, 13 seconds, clean and powerful (6137). For the experienced crew, this is as good as it gets in the forecast.
Tuesday the 25th eases off nicely. Clean, fun-sized swell, 6.2ft in the morning, 5.2ft in the afternoon, with light winds. A great follow-up day.
Wednesday the 26th sees the swell bump back up to 7.9ft-8.2ft, but the wind turns onshore and messy. Not the best.
Thursday the 27th is back to form. Clean offshore wind, 7.5ft, good energy, and clean conditions all day. Another solid call for the advanced surfer.
Friday the 28th morning is a sleeper hit. Glassy, 8.2ft of SW swell (3395 energy), and light winds. Excellent quality for those who can paddle out.
Saturday the 29th through Sunday the 30th fades out. Swell drops to 4.9ft-5.9ft, but the wind is ugly, onshore and choppy. Not worth the paddle.
So, to wrap it up: the two true standouts are Tuesday the 18th for a full day of offshore bliss, and Monday the 24th for the big, clean, powerful groundswell. Get out there if you can handle it.

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.

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.
