The Lowdown
G'day, I'm Rusty. Let's talk about Boneyards.
Alright, we've got a bit of a slow start here, but there's some serious firepower on the way. The first real action is on Tuesday, the 21st. That morning, the wind goes glassy, and we're looking at a 8ft SSW groundswell with a very long period of 14 seconds. The combined energy is monstrous (2351). This is proper, powerful stuff. Because of that long period, those waves will be holding up really well, but it's a reef break, so it'll handle it. With that size and period, this is definitely one for the experienced crew only. The afternoon cleans up with a sweet cross-offshore wind and a 10ft SW swell (2736 energy). It's slightly bigger, but the wind is cooperating, so the shape will be there.
Then we get a bit of a lull with messy, onshore winds Wednesday and Thursday, but the real standout is Friday, the 24th. The morning is a beauty. We've got a massive 12ft SW groundswell, a very long 15-second period, and a clean cross-offshore wind from the SSE. The combined energy is a massive 4823. It's a true heavyweight session for the experienced. The afternoon drops a bit to 10ft, still clean, but with a moderate breeze.
The weekend of the 26th and 27th is looking excellent as well. The 26th starts with a long-period 4ft SSW groundswell (17 seconds) and a light offshore wind, glassing up by the afternoon to 7ft. Perfect for a more relaxed session if the 12ft days are too heavy. The 27th Monday morning pumps again with an 12ft SSW swell and a 17-second period, but the wind is stronger, still cross-off but a fresh breeze.
After that, the swell drops off and the wind turns nasty. From the 28th through to the 3rd of August, it's a write-off with strong, onshore winds and messy, poor conditions. There's a brief window on the 29th with a clean offshore breeze and a smaller 4ft SW swell, but it's not a standout.
So, the pick of the bunch is Tuesday the 21st for the glassy morning, and then Friday the 24th for the absolute peak size and power. The weekend of the 26th/27th also offers a great, slightly less intense alternative. Get out there for those windows.
Rusty out.

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.
