The Lowdown
Alright, this is Rusty. Let’s get into it.
We’ve got a bit of a wait ahead for truly clean conditions at Boneyards, but there’s some serious size lurking in the back half of the forecast. The pattern starts slow with a solid pulse of WSW groundswell arriving early in the period, but the wind is the problem at first. That changes as we go.
Tuesday morning (15th) is a write-off. That 8ft WSW swell has got some punch – combined energy of 2162 (moderate to strong) – but the 25 km/h easterly cross breeze is making a mess of it. The afternoon is where it gets interesting. The wind swings southerly and goes offshore, light at 15 km/h, and the 7ft WSW groundswell cleans right up. This is the first proper window. It’s not huge, but it’s got that long 14-second period, so the waves will have shape and push. For an intermediate, this is a good one. Boneyards can get a few bodies on it sometimes, so expect some company.
Wednesday morning (16th) drops right off, and the onshore wind kills it. But that afternoon – 3ft, glassy, clean. It’s small but if you’ve got a log, that’s your window.
Thursday (17th) and Friday (18th) are a write-off. Strong onshore winds, messy. Friday afternoon (18th) does show a brief window with a 5ft swell and an offshore breeze, but the combined energy jumps to 2076 and the period stretches to 17 seconds – that’s a very long-period groundswell. At a sandbar setup like Boneyards, that kind of period can make things a bit straight and tricky. It’s a maybe.
Now, Saturday the 19th. This is the first standout. The swell builds to 10ft with a combined energy of 4107 (strong), coming from the WSW with a 14-second period. The morning has a cross-off wind, 30 km/h from the WSW. That’s going to be big, powerful, and raw. This is not for beginners – at 10ft, it’s strictly for experienced surfers. The wind is on the limit, but the size is there. This is a real heavyweight day.
Sunday (20th) is smaller but still bumpy. Monday (21st) is a complete mess with strong onshore winds.
The next real standout is Tuesday the 22nd. The swell is 8ft to 10ft, WSW groundswell with a 14-15 second period. The combined energy is 3347 to 4020 (strong). The wind is cross-off, 20-25 km/h from the WSW. This is clean and solid. It’s a powerful, consistent swell. Another day for the experienced crew.
Thursday the 24th morning looks promising: 10ft, 15-second period, 3699 combined energy, and a southerly offshore wind at 30 km/h. That’s a strong offshore, but it’s clean. Again, big and only for experts.
Now, Friday the 25th. This is the biggest day of the whole run. 13ft swell, 18-second period – that is a monster groundswell. Combined energy hits 10905 (very strong). The wind is a fresh southerly offshore at 35 km/h. That is a full-on, heavy, powerful day. This is for elite surfers only. The offshore wind will hold it up, but at that size and period, it’s going to be a serious paddle and a serious drop. One for the chargers.
Saturday the 26th is still big but dropping: 8ft, 17-second period, combined energy 3936, with a moderate offshore breeze. This is still excellent for experienced surfers, but more manageable than the day before.
The last week tapers off. Sunday (27th) is small and clean-ish, Monday (28th) is onshore and messy. Tuesday the 29th morning has a 8ft SW groundswell, 15-second period, and a gentle offshore. That’s a very good window for experienced intermediates and above. Clean, powerful, but not insane.
Wednesday the 30th is the final session: 6ft WSW, 14-second period, moderate offshore. A solid way to close out the period.
So, the standouts? Friday the 25th is the big one – 13ft, 18-second groundswell, offshore wind. That’s a proper date with destiny. Saturday the 26th and Tuesday the 29th morning are also excellent. The early part of the period has a few small windows, but the real magic is in the last ten days.
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.

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.
