The Lowdown
Alright, Rusty here. Let’s have a look at what’s cookin’.
First off, we’re looking at a real mixed bag, and for the first couple of days, honestly, it’s a write-off. Tuesday the 25th is ugly – solid 8ft of messy, wind-affected swell with a stiff cross-off breeze making it lumpy. The water's sitting at 58°, which is a touch colder than usual for this time of year, so you’ll want the thick rubber. The combined energy is huge at 2549 (moderate), but the quality is just not there.
Things finally turn a corner on Wednesday the 26th. The morning shows a cleaner 5ft SW groundswell, period around 13 seconds, with an offshore breeze. By the afternoon the wind drops to a gentle offshore, the swell sits at 4ft, and the combined energy is 1094 (moderate). This is your first real window for a paddle, and it’s gonna be clean, lined-up, and all yours if you can get out early. This is the standout of the first week.
Thursday the 27th goes back to poor with a cross-onshore wind, and Friday the 28th is only average. Saturday the 29th afternoon offers a glimmer: 6ft from the WSW, 14 seconds, combined energy of 1492 (moderate) and a clean, cross-off breeze. That’s a good back-up session for the weekend.
Now, hold onto your board. Into the first week of September, the ocean wakes up proper. Tuesday the 1st of September stays marginal, but then Wednesday the 2nd sees a big ramp-up with 12ft of swell, combined energy hitting 4301 (strong). Thursday the 3rd is the absolute standout of the entire run – 16ft of SSW groundswell, a strong offshore wind, and combined energy screaming at 8744 (very strong). This is not for beginners. This is big, powerful, expert-only territory at Boneyards. The period is 11-12 seconds, which keeps it a bit more manageable on a reef setup, but it’s going to be fierce. Friday the 4th is the hangover, dropping to a much friendlier 5ft with light offshore winds – a good day for the mid-week crew to get clean, smaller waves.
There’s a notable gap in quality from around the 7th of September onward, with small, wind-affected surf and lower energy readings. The final standout is on Sunday the 6th of September: 6ft SW swell with a 15-second period, combined energy at 1313 (moderate), and a gentle offshore wind. That’s a beautiful, long-period groundswell, perfect for the reef at Boneyards, offering well-shaped waves and long lulls between sets.
So, to wrap it up: Wednesday the 26th is your first clean, fun session. Thursday the 3rd of September is the big, powerful highlight for experts only. And Sunday the 6th of September is your sweet spot for a clean, long-period swell on the reef. No crowds mentioned, but with a spot like this, expect a few locals when it’s on.
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.
