Alright, listen up. It’s been a bit of a wait, but we’ve finally got some proper swell on the way. The first real chance to paddle out kicks off on Wednesday the 2nd of September at Boneyards. This spot is a reef break, so it’s for the experienced crew.
Wednesday afternoon is looking pretty special. We’ve got a solid 10ft swell rolling in from the SW, with a period of 13 seconds. The wind is a clean cross-off from the S at 9 mph, which is going to keep the lines tidy. The combined energy of all swells is a hefty 2723, so there’s a lot of power in the water. The water temp is sitting at 58°, which is a bit colder than normal for this time of year, so don’t forget a decent hood. This is definitely a standout for the bigger wave hunters.
We’ll see another good window on Thursday morning the 3rd. The swell has dropped to 6ft from the WSW, still with a nice 13-second period and clean offshore winds from the SE at 16 mph. It’s a bit more manageable than Wednesday, but still a serious wave. The energy is still strong at 853. The wind picks up hard in the afternoon, though, going to 34 mph, so that morning session is your only shot.
After a run of nasty, windy days, the next real highlight is Sunday morning the 6th of September. The swell is back up to 7ft from the SW, but this time the period is a very long 18 seconds. This is a proper groundswell. The wind is a gentle offshore from the E at 9 mph, and the combined energy is a massive 2745. The conditions will be clean and powerful, but with that long period, it might be a bit too straight for a beach break set-up. It should be a dream on the reef though. Sunday afternoon stays good, with 6ft SW swell and 16-second period, and a clean cross-off breeze.
We’ve got another promising morning on Thursday the 10th of September. The swell is 5ft from the WSW with an 11-second period and fresh offshore winds from the ESE. The energy is moderate at 874. Friday the 11th of September is looking like a solid morning too, with 5ft WSW swell and a gentle offshore breeze. The energy is 658, and the conditions are set to be clean.
Then we hit a bit of a lull. There’s a decent chance for a wave on Sunday the 13th of September, with a 4ft SSW swell and a longer 14-second period, but the wind is a light cross-on, so it might be a bit bumpy.
The final session to look at is Thursday the 17th of September. The morning offers 5ft SW swell with a 12-second period and clean cross-off winds. The energy is 730. The afternoon is also looking good with 5ft swell and very clean conditions. This is a good, consistent end to the forecast.
Overall, Wednesday the 2nd and Sunday the 6th are the two biggest standouts. The mid-week swell is massive and powerful, and the Sunday swell is a long-period groundswell with perfect wind. Get your board ready.

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.
