The Lowdown
Alright, let’s talk about what’s brewing. The main spot is Boneyards, a reef break that’s not for the faint of heart. It’s an inconsistent wave, so when it’s on, it’s a treat. The water is sitting at 57°, which is a bit chillier than usual for this time of year, so you’ll want a thicker suit.
The action starts on Saturday, August 8th. The morning has a 10ft swell out of the SW with a 13-second period, but that north wind at 12 mph is making it a messy, choppy affair. The afternoon is a different story – the swell jumps to 13ft from the SW, and the wind cleans up to a cross-off. The ocean is absolutely loaded with energy (6120), but anything over 8ft is for the experts only.
Sunday the 9th stays big, with 10ft to 12ft of SW/SSW swell, but the wind is screaming from the SSE at 25 mph. It’s clean, but it’s a battle out there. The energy is still massive (3501). Monday the 10th drops to a more manageable 6ft, but the wind is still howling at 25 mph. The afternoon is interesting – 6ft with a strong offshore wind, making it clean but a real chore to paddle into. The energy is moderate (1679).
The real standout is Wednesday, August 12th. The morning has 6ft of SW swell, but the period is a very long 18 seconds, and the wind is a gentle offshore breeze. The energy is strong (2359). That’s the kind of glassy, long-period groundswell that turns Boneyards into a dream. The afternoon is even better with 7ft, light winds, and the same long period. This is the pick of the whole run – clean, powerful, and set for the experienced surfer.
Thursday the 13th is also a cracker. The swell is 8ft from the SW in the morning, again with that 18-second period, but the wind is a cross-off. The energy is massive (4257). It’s near the top of the range, but it’s going to be a barrel for those who can handle it. Friday the 14th sees the wind turn onshore, and the quality drops off a cliff. The swell is still there, but it’s a choppy mess through the weekend.
We get a bit of a lull, but there’s a promising window later. Monday, August 17th looks good again, with a 7ft WSW swell, a light offshore wind, and clean conditions. The energy is moderate (1345). Then, the real long-range punt comes on Sunday, August 23rd. The morning has 12ft of WSW swell, a 12-second period, and it’s absolutely glassy. The energy is huge (3883). That’s a very promising, clean, big day for the experts. The afternoon has 13ft, but the wind swings cross-shore, so the morning is the one to aim for.
Overall, the surf is on and off, but the standout is definitely Wednesday, August 12th – that’s the session you don’t want to miss. The long-range Sunday the 23rd is a big promise, but it’s a long way off, so keep an eye on the charts.

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.
