The Lowdown
G’day, it’s Rusty here. Let’s dig into the surf coming up at Boneyards. The first couple of days are flat, but then we get a real solid run of swell starting on Sunday.
The first good call is Sunday, September 6th morning. Boneyards will have a clean 8ft swell from the SW with a very long period of 18 seconds. The wave energy is pumping (combined energy of 3681) and with a moderate offshore breeze from the ESE, the conditions will be clean. That size and power is only for experienced surfers; beginners need to sit this one out. The water temperature is a chilly 58°, which is about 2° colder than usual, so you’ll want a thick wetsuit.
The absolute standout is Saturday, September 16th morning. We’re talking glassy conditions, clear sky, and a solid 10ft swell from the WSW with a 13-second period. The combined energy is a strong 3451. With zero wind – dead flat glass – this will be the cleanest, heaviest surf of the window. It’s big and powerful, so only for experts. This break can be inconsistent, but when it’s on like this, it’s a jewel, though you can expect some company.
Then Monday, September 18th morning delivers again – a consistent 12ft west swell, light offshore winds from the ESE, and wave energy of 4514. The period is 13 seconds, giving it good shape. This is expert territory due to the size.
Respect the ocean and stay safe.
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.
