The Lowdown
Alright, Rusty here again, giving it to you in feet and miles an hour.
So Boneyards is a reef that doesn't fire every day, but when it does, it's a proper wave. The water's sitting at about 57°F right now, which is a bit colder than usual for this time of year, so bring the rubber.
The clear winner is Wednesday the 12th. You've got a solid 6ft SW groundswell with a very long 18-second period. The combined wave energy is pumping at 2452 (strong energy). Wind is light and cross-off from the ENE in the morning, then goes offshore from the east in the afternoon. This is going to be clean, heavy, and lined-up. Not for the faint of heart – this is expert-only territory. Crowds can pop up here sometimes, and on a day like this, you can bet a few will be out.
Thursday the 13th keeps the size up at 8ft SW swell, period still a long 17 seconds, and energy spiking to 3564 (very strong energy). Morning is okay with a light cross-shore from the NNE, but the afternoon gets messy as the wind picks up from the NNW.
Friday the 14th through the weekend is mostly blown out or onshore. Skip it.
Saturday the 15th is another good one. Swell drops to 6ft from the WSW, period at 13 seconds, but the wind is light and cross-off from the SSE. Energy is at 1280 (moderate energy). This is much more user-friendly – still punchy, but cleaner and a better paddle for the strong intermediate.
Monday the 17th is for the serious crew only – 8ft WSW swell, 13-second period, energy at 2477 (strong energy), and a moderate cross-off from the SSE keeping it clean.
Looking out to Saturday 22 August, you've got 5ft SW swell with a 14-second period, energy at 1265 (moderate energy), and offshore wind from the SE. Clean and lined up.
And then a real oddball on Tuesday the 25th: tiny 3ft swell but with an insane 19-second period, glassy wind from the SW. Energy is moderate at 888. Not powerful, but those long-period lines could be magic on a longboard if the tide's right.
After that, the second week gets patchy with wind and inconsistent swell. There's a few days with nothing worth paddling out for.
Best bets overall: Wednesday the 12th and Saturday the 15th for the best combo of size, clean wind, and quality. Experienced surfers, look at Monday the 17th too. Saturday the 22nd is a solid backup plan.
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.
