The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.
We’re looking at a solid run of swell, but it’s not all clean sailing. The first few days are tidy, then we get a rough patch of wind, before things clean up again for some real standouts later on. The water temp is sitting at 59°, which is a touch cooler than average for this time of year, so you’ll want a good wetsuit.
Tuesday morning (4th August) kicks things off at Boneyards with a clean 4ft SW swell. The wind is glassy, and the combined energy is moderate (423). It’s a sweet, small start. The afternoon stays clean with a 4ft SW swell and a light offshore breeze.
Wednesday (5th August) is a write-off. The wind howls from the N/ NNW at 22 mph, turning the 8ft to 8ft SW swell into a lumpy mess. There’s heaps of energy (2689-2790), but it’s not for paddling.
Thursday (6th August) sees a big jump in size to 12ft, but the wind is cross-off. The energy is strong (3920-3508), and conditions are described as clean, but the quality is marginal. For experienced surfers, it might be worth a look, but it’s not the best of the run.
Friday (7th August) is a proper standout. The morning delivers a clean 10ft SW groundswell with a 14-second period and offshore wind. The energy is through the roof (4688). This is excellent for experienced surfers only – it’s big, powerful, and clean. The afternoon holds up but gets a bit more cross-off.
Saturday (8th August) drops off a bit. The wind is onshore or cross-on, and the 10ft SW swell is messy. Not one to get excited about.
Sunday (9th August) is strong again with 12ft to 10ft SW swell, but the wind is strong cross-off. The energy is high (3290-1970), but the wind speeds are up around 28 mph, making it a tough paddle.
Monday (10th August) the swell drops right back to 5ft. The wind is fresh offshore, which is clean, but the energy is weak (415). The afternoon is even smaller with strong offshore wind that’ll make it hard to get into waves.
Tuesday (11th August) is tiny – 2ft to 2ft. The morning is a washout, but the afternoon shows a very long-period 24-second SW groundswell with 2ft. That energy (735) is interesting, but it’s a very long period, so it might be a bit straight at a reef. Still, glassy conditions make it a fun option for a small-wave board.
Now, for the real second-week highlight. Wednesday (12th August) is an absolute cracker. Morning has a 7ft SW groundswell with an 18-second period, light cross-off wind, and energy (2799). The afternoon turns glassy with a 8ft SW swell and 17-second period. This is excellent surf for experienced surfers. Clean, powerful, and consistent.
Thursday (13th August) is another great day. The morning is a bit cross-on for the 8ft WSW swell, but the afternoon cleans right up with light cross-off winds and the same size swell. Energy (3037-3928) is strong. Again, this is for experienced surfers.
Friday (14th August) through Sunday (16th August) the size drops and the wind gets messy. There are some clean windows, but the quality is marginal. Best to wait.
Monday (17th August) sees a massive 15ft WSW swell, but it’s with strong onshore wind. The energy is extreme (7462), but it’s a total mess. This is kite-surfing territory, not paddling.
Tuesday (18th August) is a late highlight. The morning has a 10ft WSW groundswell with offshore wind and excellent conditions for experienced surfers. Energy (3160) is strong. The afternoon is a bit smaller but still clean.
Wednesday (19th August) rounds it out with a solid 10ft WSW swell and clean cross-off winds. Energy (2962-3675) is strong. Another good day for the experienced crew.
The absolute standout is Friday morning (7th August) with that big, clean, offshore 10ft SW groundswell, and Wednesday (12th August) with the glassy, long-period groundswell. Boneyards is an inconsistent reef, so these are special windows that you need to jump on. The crowds are sometimes an issue, so get there early.
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.
