The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Boneyards over the next couple of weeks. This is a reef setup that’s inconsistent and really only comes alive when the conditions line up just right. It’s an exposed spot, best with a W swell direction, but we’re seeing a lot of SW and WSW energy in the mix.
The water’s sitting at 58°, which is a bit colder than normal for this time of year – you’ll feel that bite for sure.
The first real shot of decent surf is Sunday morning, the 13th. We’ve got a solid 7ft SW groundswell with a 14-second period pushing in. The combined wave energy is strong, at 1665, and with a light ESE offshore breeze, those waves are going to be clean. This is excellent for experienced surfers only – it’s too big for beginners and the reef bottom demands respect. Crowds can pop up here sometimes, so you might have some company.
Sunday afternoon sees the swell drop a touch to 6ft, but the wind swings to a light cross-on from the NNW. It’s still okay, but not as pristine as the morning. Conditions get pretty average from Monday the 14th through to Thursday the 17th. We’ve got fresh to strong cross-onshore winds and lumpy, messy surf. The period drops right off on Monday afternoon to a short 6 seconds – that’s just wind chop. Nothing worth paddling out for.
Friday the 18th shows some improvement with a fresh offshore from the SE and a clean 6ft SW swell at 13 seconds. It’s marginal, but there’s potential for a few good ones if you pick your bank.
Now, here’s where it gets interesting. Saturday the 19th is looking sweet. The morning has a slight air and a clean 6ft SW groundswell at 14 seconds. The energy is strong at 1459, and it’s glassy. That’s a standout window for the first week – clean, solid, and lined up. The afternoon holds with a gentle breeze and similar 6ft swell.
We roll into the following week with a bit of a gap in quality. Sunday the 20th and Monday the 21st have clean surf but the winds are cross-off or side-shore, and the energy is moderate to strong. Not terrible, but not firing. Tuesday the 22nd morning is a gem though – a moderate offshore from the ESE, 6ft WSW swell at 13 seconds, and excellent conditions for experienced surfers. That’s another one to circle.
Things fall apart again from Wednesday the 23rd through Thursday the 24th with poor surf and messy winds. Then Friday the 25th hits like a bomb. We’ve got an 12ft WNW swell on Friday morning with a light offshore and clean conditions. The energy is very strong at 2484. That’s big and powerful – experts only. By the afternoon, it jumps to 15ft with a moderate breeze. The combined energy is huge at 4298. This is a serious, serious swell.
Saturday the 26th holds big, with 12ft W swells and a fresh cross-off breeze. Still clean, still heavy. This whole stretch from the 25th to the 28th is pumping with consistent, strong groundswell. The biggest day looks like Monday the 28th, with a 16ft SSW swell and a 12-second period. The combined energy is massive at 7388. The winds are strong but cross-off, keeping the surface clean. That is a massive day for the experts. The swell is way too big for anyone else.
So, the standout best is Monday the 28th of September for sheer power, but the cleanest, most user-friendly of the big swells is probably Friday the 25th morning. After that, the surf drops back down but stays clean and big through the end of the period. Boneyards is a fickle spot, but when it turns on, it turns on hard.
Rusty.

Information about the Boneyards Surf forecast
The above surf forecast table for Boneyards provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Boneyards can be found by selecting the local surf guide option on the grey menu. Our Boneyards 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 (Boneyards) 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 Boneyards 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.
