The Lowdown
Alright, Rusty again, but in feet and knots. Let’s talk Boneyards.
Right now it’s flat and ugly. The first real chance to surf comes Wednesday the 26th.
That morning shows 4-5ft of SW groundswell with a 13-second period, and a clean offshore wind out of the ESE. Combined swell energy is pumping (1171). It’s not huge but it’s clean. The afternoon glassed off even more with a light offshore breeze and 4ft swell. Good for intermediates who know the reef.
Thursday the 27th goes sideways – cross-on wind and junk. Skip it. Friday the 28th afternoon gets better with a 4ft WSW swell at 14 seconds, clean cross-off breeze, energy hitting 779. Surfable.
Saturday the 29th morning is glassy – no wind, 4ft WSW swell at 13 seconds. The ocean looks like a lake. Energy is moderate (729), but the surface is perfect. Best session of the first week for a clean, relaxed paddle.
Sunday the 30th pushes up to 8ft of SW swell for the morning. That’s expert territory. Energy is strong (2356), and it’s clean, but the size and tide make it a challenge.
Then the wind turns nasty through Monday and Tuesday. Wednesday the 2nd of September is a full-on mess with 11-12ft of WSW swell and strong cross-onshore winds. That’s kite territory, not paddle.
Friday the 4th of September sees a 10ft S swell with a fresh offshore breeze from the SE. Energy is huge (3054), but the swell direction isn’t ideal for Boneyards. Big and clean but only for the experienced.
Now, Sunday the 6th of September is the one. Morning brings 7-8ft of SW groundswell with a very long 17-second period, light offshore ESE wind, and energy at 3540. The afternoon bumps to 8ft with 16 seconds (3718). This is the best swell of the 16-day window. That long period means it’ll barrel on the reef, but it can be a handful. Boneyards does get crowded, so be there early if you want a piece.
The tail end from the 7th to 9th September is mostly blown out or poor.
If you want a clean, easy day, paddle out Saturday the 29th morning in the glass. If you want a proper, powerful swell, circle Sunday the 6th of September – that one has serious potential for the right crew.
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.
