The Lowdown

Alright, folks, Rusty here. Let's break down what's coming for our local stretch.

The forecast is a bit of a slow starter, but there's a golden window that's worth marking on the calendar. The early days are a bit of a mixed bag with some strong winds, but we've got a serious pulse of swell arriving mid-week that's got my interest.

First thing, the water is sitting around 58°, which is a bit cooler than usual for this time of year, so don't forget the booties.

We kick things off on Sunday, the 9th of August, with a solid 13ft SSW swell hitting Boneyards. The energy is huge, but the wind is howling out of the SSE at 25 mph, making it a cross-off mess. It's surfable, but it's a grunty, challenging paddle. Not for the faint-hearted.

Monday the 10th is another day of big, strong wind, with the swell dropping to 10ft but still holding strong energy. The wind stays strong, making it a real battle.

Tuesday 11th August is where things start to turn. The swell eases a touch to 6ft from the SSW, but the wind switches offshore from the East at 12 mph. The morning looks clean and lined up, with that swell period pushing 12 seconds. It's a proper session for the experienced crew.

The real standout, though, is Wednesday 12th August. A chunky 6ft to 7ft SW groundswell, with a period of 17-18 seconds, pours in. The energy is strong, and the wind is light, offering a clean glassy surface in the afternoon. This is prime, powerful reef surf. The long period means it'll be a freight train, so it's best left for the experts, but the quality is undeniable.

After Wednesday, things get a bit messy. The swell stays in the 7ft range, but the wind cycles through cross-on and onshore directions. Thursday 13th sees an 8ft SW swell with a very long 18-second period, but it's a cross-off wind that might make it tricky.

The middle of the month is a bit of a write-off for clean conditions. There's a gap of several days with no real recommendations, as the wind is unfavourable and the swell is lumpy.

But then, Monday 17th August delivers again. The swell jumps back up to 10ft from the WSW, with a healthy 15-second period. The energy is massive. But the best part? The wind is glassy. Absolutely glassy. Morning and afternoon. This is a day for the experienced surfer who wants a serious, powerful, clean wave. It's a big, heavy day, but the conditions will be about as good as they get for that size.

After that, the surf drops off considerably. The second week sees smaller, weaker swells, with the wind staying mostly onshore or cross-off. The final weekend, the 23rd and 24th of August, shows a return of a solid 8ft to 10ft SW swell, but the wind is a moderate cross-off, which might keep it lumpy. It's promising, but a long way out, so keep an eye on it.

Overall, the standouts are clear: Wednesday 12th August for that perfect, clean, long-period groundswell, and Monday 17th August for the sheer power and glassy conditions. Both are for the experienced crew, but they are the sessions to shoot for.

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.
