The Lowdown
G’day, Rusty here. Let’s chew the fat on what’s coming up for Boneyards.
Alright, the first week or so is a bit of a mixed bag. We’ve got some solid groundswell on the way, but the wind is going to be a proper headache for a lot of it. The good news is, the second half of the outlook looks absolutely nuking, especially for the experienced crew.
We kick things off on Friday, July 31st. It’s not the best of starts, with a modest 4ft swell from the SW and a light SE wind keeping it clean. The water’s sitting at 59°F, which is just a touch under the average for this time of year, nothing to worry about. The energy is moderate (484). It’s a surf, but it’s not going to get the heart pumping.
Saturday, August 1st is where it starts to get interesting. The morning session is looking prime with a 4ft WSW swell and a glassy ENE breeze. That’s the kind of clean you dream about. The energy is up a notch (663) and the period is a solid 14 seconds, so it’s a proper groundswell. This is a standout for the early part of the run. The afternoon stays clean but the wind goes cross-off, so the morning is the pick.
Sunday the 2nd and Monday the 3rd are a bit of a write-off. The wind swings onshore, and while the swell is still there, the quality drops. By Monday, the swell hits 5ft but the energy is starting to build to 1137, but the cross-on wind just ruins it. Tuesday the 4th is even worse, with the afternoon session turning into a complete mess with onshore wind and a drop in size.
Now, hold on to your board, because Wednesday, August 5th is a big one. We’ve got a 10ft SW swell on the way, but it’s being hammered by a fresh 30 km/h cross-on breeze. The energy is massive (3412) but it’s lumpy and ugly. This is more of a kite-surfing show than a paddle-surfing session. Not for us.
Thursday, August 6th is a redemption day. The swell jumps to 13ft from the SW, and the wind goes clean and offshore from the SSE. That’s a big, powerful groundswell (energy of 8001) with a 14-second period, and it’s going to be a serious challenge. The afternoon is even better, with a 15ft swell and a clean offshore wind from the ESE. This is for experts only – the size is well over 8ft. It’s a standout, but you need to know what you’re doing.
The weekend of the 7th and 8th of August is a bit of a rollercoaster. Friday the 7th is messy with onshore wind, but Saturday the 8th brings it back. The morning has a 10ft swell with a clean offshore wind from the SE, and the afternoon is even better: 12ft, clean offshore, and a solid 13-second period. This is another excellent window for the experienced surfers.
Things go downhill again on Sunday the 9th and Monday the 10th with onshore winds and choppy conditions. The surf is there, but it’s not worth the paddle.
But then we get to Tuesday, August 11th. The afternoon session is a serious standout. An 12ft WSW swell with a very long 15-second period, and a clean cross-off wind from the south. The energy is massive (5985). This is a rare, powerful groundswell that will be a thing of beauty for the experts.
Wednesday, August 12th is another cracker. The morning is glassy with a 13ft swell from the WSW. Absolutely perfect conditions for the big wave riders. The afternoon stays clean but the period drops a touch.
The last major standout is Saturday, August 15th. The morning session is world-class: 13ft of WSW swell with a 15-second period and glassy conditions. The energy is insane (7899). This is a real highlight. The afternoon actually gets bigger, hitting 16ft with the same long period, but it goes a bit cross-shore. Still, the morning is the one to circle on the calendar.
Crowds at Boneyards can be a factor sometimes, so keep that in mind for the good days. Overall, the second week is where the magic happens, but those first few days of August have some clean windows too.
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.
