The Lowdown
Righto, Rusty here. Let’s have a look at what’s coming down the line for Boneyards.
This is a reef break that’s inconsistent and needs the right swell to fire. The best of the run is coming up mid-week, with a couple of windows where it’ll be worth paddling out. But you’re going to have to be patient early on.
Sunday the 9th kicks off with a big 10ft to 13ft SW groundswell, period 12 seconds, and the wave energy is strong at 3001 to 7110. Problem is, it’s blowing 25 mph from the SSE, cross-off, but that’s a fresh breeze making things challenging. The morning rain doesn’t help either. This is expert territory at that size, and the wind is a struggle.
Monday the 10th drops to 6ft to 6ft, wind still strong at 25 to 28 mph. The afternoon turns offshore, which cleans it up but makes it a grind to paddle into. Not the day for a relaxed session.
Tuesday the 11th is where it starts to get interesting. Morning swell 6ft from the SSW, period 12 seconds, and the wind backs off to 12 mph from the east – offshore and clean. The energy is moderate at 950. This is a solid, manageable size. The afternoon gets even better: 4ft, same direction, wind drops to 9 mph ESE, still offshore, and the surf is glassy. This is a good, clean window for an intermediate surfer.
Now, the standout is Wednesday the 12th. The swell holds at 6ft to 7ft from the SW, but look at that period: 17 to 18 seconds – that’s very long period groundswell, which Boneyards as a reef should handle beautifully. The wind goes light, 3 to 6 mph, cross-off, and it’s clean with excellent conditions for experienced surfers. The combined wave energy is strong at 2468 to 2783. This is the best session of the outlook.
Thursday the 13th is still solid, with 7ft to 5ft swell, very long period 16 to 18 seconds, but the wind is more cross-off breeze at 9 to 12 mph. Still clean, but not quite as perfect as Wednesday.
From Friday the 14th through Sunday the 16th, the swell hangs around 6ft to 6ft, but the wind turns cross or cross-on, and conditions get lumpy. The afternoon of Saturday the 15th is glassy with 0 mph wind and 6ft swell – that’s a good call for a late session if you’re desperate. But quality drops off.
The second week starts to fade. Monday the 17th kicks up to 8ft with onshore wind, not ideal. From Tuesday the 18th onward, the swell gets smaller and the wind turns strong again, mostly cross-off or onshore. The last few days from Friday the 21st to Monday the 24th are poor, with small swell under 5ft and fresh wind creating chop. Not worth the drive.
Bottom line: Wednesday the 12th is the standout – get in the water if you can. Tuesday the 11th afternoon is also a good, clean option. After that, it’s a waiting game with long gaps of rubbish.
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.
