The Lowdown
Alright, let’s get into it.
We’ve got one spot on the radar: Boneyards. It’s a reef break, intermediate territory, and it’s inconsistent – so don’t expect it to fire every day. It needs a specific window. The water's sitting at 57° – about 3° colder than normal for this time of year, so you’ll want a good 4/3, maybe booties if you feel the chill.
Right now, the surf is cranking. Sunday morning (September 6th) is a proper standout. You’ve got a solid 8ft SW groundswell with a very long 18-second period pushing in – that’s proper energy. The combined energy is pumping at 3471 (strong). With an ESE wind holding offshore, it’s gonna be clean and lined up. This is big though – over 8ft, so this is strictly for experienced surfers only. If you’re not confident, sit this one out. Crowds are possible here sometimes, so get in early. This is the pick of the whole forecast.
Sunday afternoon stays good – 7ft SW, 16-second period – still excellent for the experienced crew. Winds shift SE, still offshore. Energy is still strong at 2272.
Monday morning (7th) drops a notch. Still 7ft SW but the period drops to 14 seconds, and the wind goes cross-on from the NNW at just 3 mph – small wind ripples will creep in. It’s okay, but not a standout.
Monday afternoon cleans up again: 7ft SW, cross-off wind from the south, and the energy is 1339 (moderate). Not as powerful but still rideable.
Tuesday morning (8th) is small and glassy – 3ft WSW, 12-second period, and glass conditions. Energy is down to 585 (weak). Could be fun on a log, but it’s not going to bowl.
From Tuesday afternoon through to Wednesday the 9th, the swell fades significantly and the wind gets messy or cross-shore – we’re looking at small, weak waves. Not worth paddling out for.
Now, hold onto your board. Thursday the 10th sees a big pulse – 10ft SW groundswell with a 16-second period, but the wind is a strong cross-off from the SE at 22 mph. Energy is massive at 5089 (very strong). The comment flags it as marginal – likely blown out or hard to manage. This size is experts only, and with that much wind it might be more of a tow-in or even a kite situation than a standard paddle session.
Friday the 11th is still big – 7ft WSW – but the wind cranks offshore from the SE at 28 mph. It’s going to be almost impossible to get out; the paddle will be brutal. This is more about survival than fun.
Saturday the 12th offers a slight reprieve. Morning has 8ft SW at 16 seconds with a fresh offshore ESE breeze – cleaner and more manageable than Friday. Energy is 2825 (strong). Afternoon stays solid at 8ft SW with clean offshore winds. Still big, but cleaner. Possibly the second best window of the whole run for experienced surfers.
From Sunday the 13th through Tuesday the 15th, it’s poor. Cross-onshore winds, lumpy, choppy – not worth your time. Swell stays between 4ft and 10ft but the wind wrecks it.
Wednesday the 16th sees a shift. Light rain, 8ft to 10ft WSW swell, but cross-off winds from the SE at 19–22 mph. It’s clean but still big. Energy around 3274 (strong). This is for the experts again.
Thursday the 17th pushes even bigger – 12ft WSW, 13 seconds, with strong cross-off winds. Energy is 4167 (very strong). This is heavy, powerful, and for very experienced surfers only.
By Friday the 18th, the swell backs off to 5ft and smaller, but the wind is still howling – near gale offshore. It’s going to be tough.
The last few days, 19th to 21st September, fade into smaller, weaker swell with inconsistent winds. Nothing exciting.
Overall, the standout is Sunday the 6th – early morning. If you’re experienced and you want the best waves of this whole 16-day run, that’s your window. Saturday the 12th is your backup. Everything else is either too big with bad wind, too small, or just plain messy.
Stay safe out there.

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.
