The Lowdown
Alright, Rusty here, let’s get into it.
We’ve got a bit of a slow start, but Boneyards has some serious juice coming through later in the period. The first few days are pretty average, with a marginal Thursday morning on offer. Thursday morning the 27th sees knee-to-waist high, 5ft swell from the south, period around 12 seconds, so it’s got some weight, but that cross-onshore NNW breeze at 6 mph puts a bit of a ruffle on it. Wave energy is moderate (863). Not great, not terrible. Thursday afternoon stays similar but a bit more chopped up.
Friday the 28th is where things start looking up. A glassy, clean 4ft south swell on Friday morning with light wind – that’s the kind of session you paddle out early for. Wave energy dips a bit (645), but the quality makes up for it. Friday afternoon holds clean with a longer 14-second period from the WSW, and that cross-off breeze will keep the face nice.
Saturday the 29th morning is the first true standout of this outlook. We’ve got 6ft of WSW groundswell pushing through, a long 15-second period, and clean, light offshore wind from the ESE. This is excellent surf for experienced surfers. Wave energy is strong at 1145. The direction’s a match for the optimum, and that 15-second period will reel in nicely at this reef break. You’ll want a bit of experience under your belt for this one – not a beginner’s wave. Boneyards will have proper shape and power. Could be a few others out – crowds happen sometimes.
Saturday afternoon gets blown out by a 16 mph SSW cross-breeze, so you’ll want to be off the water by then. Sunday the 30th offers bigger, clean 8ft swell with cross-off wind, but it’s marginal – that’s a lot of water moving, and the period drops to 13 seconds. Wave energy is very strong (2151). This is expert territory. Not the pick of the window.
The start of next week sees onshore winds and dropping quality, but then we get a massive pulse on Wednesday the 2nd of September. Wednesday morning brings a serious 16ft swell from the SW with a 16-second period – that’s a very long period groundswell. Wave energy is huge at 12695. This is heavy, powerful, and only for experts. It might be too big for the reef to handle cleanly and could close out, but if you’ve got the skills and know the lineup, this is your beast. Boneyards will be working, but it’s not for the faint of heart. That south wind is clean but strong. Wednesday afternoon stays big at 15ft.
Thursday the 3rd and Friday the 4th get shredded by gale-force offshore winds – hard to even paddle into. Not worth it.
Things settle down by the 5th and 6th of September with smaller, clean conditions. Sunday the 7th and Monday the 8th see glassy mornings with waist-high groundswell, good for a longboard or a funboard. Nothing huge, but clean.
Then from the 8th of September onwards, it’s mostly onshore or cross-onshore junk until the final couple of days. The 11th of September offers a late push of 7ft SSW swell with a bit of a cross-shore chop – could be a last gamble if you’re desperate.
Overall, the real standout is Saturday the 29th of August morning for the quality and power, and the huge Wednesday the 2nd of September swell for those who can handle it. The water temperature is about 59°F, which is a bit colder than normal for this time of year – keep the steamer on.
Alright, get after it.

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.
