The Lowdown
Alright, Rusty here. Let's break down what's coming up for Off The Wall.
The water is sitting at a very unusual 54°F (much colder than normal for this time of year), so you’ll want a thick wetsuit. The first real standout is Monday morning, the 7th of September. We’ve got a solid 7ft SW groundswell, clean as a whistle with glassy conditions and a light NW breeze. The combined energy of all swells directed here is a strong 1553, so there’s plenty of grunt in the water. This is a reef break suited for advanced surfers, and with the offshore wind direction (SE) being the optimum, the waves will be well-shaped and powerful. The afternoon holds up too, dropping to 6ft but staying clean with a cross-off breeze.
Tuesday the 8th is a step down in size but still fun. The morning glass-off with a 3ft WSW swell and 12-second period will be clean and user-friendly. The energy drops to 523, but it’s a good session for a smaller board.
Now, hold onto your board for Thursday morning, the 10th of September. This is the standout of the whole run. A 10ft SW groundswell (16-second period – very long period groundswell) is rolling in with a gentle offshore breeze. The combined energy is a massive 3736. This is a powerful, deep-water swell that will set up perfectly at this reef. For experienced surfers only. The following Friday the 11th also has solid 6ft-8ft swell, but the wind is a strong 35 km/h offshore – it’s clean but paddling will be a fight.
The second week gets a bit messy. Saturday the 13th has a 7ft SW swell but the wind turns cross-onshore, making conditions lumpy and poor. From Sunday the 14th onwards, the wind picks up again, with strong cross-onshore and onshore winds spoiling the shape. Tuesday the 15th sees a huge 13ft WSW swell, but with 45 km/h onshore winds, it’s a complete write-off for surfing – that setup would be more interesting for kite surfing than paddle surfing.
The end of the run shows some cleaner days, but with strong offshore winds (45-50 km/h) it’s hard to paddle into, even if the waves are clean. The period around the 19th of September shows a brief window of moderate offshore winds and a 6ft SE swell, which could be a sneaky good session, but it’s a long way out and less certain.
The best bets are clear: Monday the 7th for a quality, clean session, and Thursday the 10th for the big, powerful groundswell if you’re up for the challenge.
Rusty.
