The Lowdown
Alright folks, Rusty here. We’ve got one spot lighting up the charts for this forecast period, so let’s get straight into it.
The opening days are a bit of a slow burn. Wednesday (September 9th) has some small swell around, but it’s nothing to write home about. The real action starts kicking in from Thursday morning. We’re looking at a solid pulse of groundswell rolling in, and it’s going to build into some proper size.
The standout window is shaping up for Thursday morning, September 10th. Boneyards is the place to be. We’re seeing a thumping 8ft swell from the southwest, with a solid 14-second period. That’s proper groundswell energy, and with the combined swell energy hitting 2590 (moderate to strong), you’ll feel the power. The wind is a light cross-offshore from the SSE, keeping things clean. This is excellent surf, but at that size, it’s really for the experienced crew. Beginners will want to sit this one out.
Sunday the 13th is another good shout. The swell drops back a touch to 7ft, but it’s still a nice southwest groundswell (14 seconds). The wind swings light offshore from the east, making for some clean, lined-up waves. Combined energy is still pumping at 1422 (moderate). This is a solid day for intermediates who missed the Thursday session.
Into the second week, there’s some real potential, but it’s further out. Friday the 18th is looking juicy, with glassy conditions in the morning and a 10ft southwest swell at a very long 17-second period. The combined energy is massive at 4515 (strong), but that long period means the sets will be spread out and the waves will be powerful and steep. That’s a reef-break day for the experts. And looking way out to Sunday the 20th, we’ve got a huge 18ft southwest swell forecast for the afternoon. That’s colossal energy (14819), but the wind will be up, making it a messy, challenging day even for the brave. That one’s a maybe for now.
It’s not all perfect. From Monday the 14th through Tuesday the 15th, a strong north-northwest wind messes things up completely. That’s a gap to avoid. Also, heads up: Boneyards is an inconsistent reef break, so don’t expect it to fire every day. Crowds can show up here sometimes, especially when the forecast looks this good.
So to wrap it up: Thursday the 10th is your best bet for quality, powerful waves. Sunday the 13th is the solid, fun option for the slightly smaller stuff. Everything after that is promising but less certain.
Stay stoked.

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.

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.
