The Lowdown
Alright folks, Rusty here. Let's have a look at what's shaping up for Boneyards (Bunker Bay). We've got a solid run of swell on the cards, but the wind is going to be the real story. This is going to be a waiting game for the right moment.
The water's sitting at 66° and a touch warmer than normal, so you're not going to need the thickest wetsuit.
We're starting off with a bang on Monday the 17th, but it's a write-off. That 16ft W swell has a massive 6730 of energy behind it, but a near gale from the WSW is going to tear it to pieces. Forget about it.
Tuesday the 18th through to Thursday the 21st is a period of dropping but still chunky swell, mostly in the 8ft to 13ft range. The wind is messy – cross, cross-on, and cross-off – meaning the wave quality is going to be marginal at best. You'd be fighting a cross-chop more than surfing. Not worth the paddle out.
Now, Friday the 21st afternoon is where it starts to get interesting. The swell has dropped to 8ft from the WSW, but the key is the wind switching to a gentle cross-off breeze. The "clean" call is a big green light. The energy is still moderate at 2350, but with 14-second period, it'll have some push. This is a solid option for experienced surfers.
Saturday the 22nd afternoon looks like a standout. The swell is a more manageable 6ft from the WSW, the period is a lovely 16 seconds, and the wind goes fully offshore – a gentle breeze from the SSW. That's about as clean as it gets, with a "very good surf conditions" call. This is your best bet of the whole run for a proper glassy session.
The following week, from the 23rd to the 26th of August, sees a rise in swell again, mostly 7ft to 10ft. The mornings on Tuesday the 25th and Wednesday the 26th both have light to gentle offshore breezes and "excellent" conditions for experienced surfers. Those are your next best bets, with solid 13 to 15-second period groundswell. Be aware that at this size, it's for the crew who know what they're doing.
Things get a bit sketchy again from the 27th, with the wind turning cross-on or onshore and finally turning into a full-on blow by the end of the month. The 30th of August has another big 8ft, 19-second period groundswell, but it's going to be a choppy mess, and the 31st and 1st of September are a complete loss with gale-force winds. Avoid those.
So to wrap it up: the standout is Saturday the 22nd afternoon for clean, offshore 6ft waves. The runners-up are the mornings of Tuesday the 25th and Wednesday the 26th for bigger, clean sets for the experienced crowd. The rest of the time, you're either fighting the wind or dealing with marginal conditions.
Stay sharp.
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.
Boneyards is 60 km (37 miles) from the city of Bunbury. If you plan a holiday in Margaret River, look for hotels and other accommodation in Bunbury. Bunbury has rooms for a wide range of budgets as well as car hire and transport links.
