The Lowdown

Alright, Rusty here again, this time in feet and miles.

We’re looking at Boneyards – an exposed reef break that wants a good W swell to shine. Water’s a bit cooler than normal for the season at 59°F.

Forget Saturday 12th September. It’s a total washout. You’ve got 8ft of SW swell but a screaming 31 mph ESE wind. The combined energy is massive at 3715, but it’s for adrenaline junkies only.

First real window is Sunday morning, 13th September. Solid 7ft SW swell with a 14-second period – proper groundswell – and a light 9 mph offshore easterly breeze. Clean, powerful, energy at 1665. This is for the experienced crew. Sunday afternoon drops to around 6ft but stays clean.

Monday and Tuesday, 14th and 15th, are dead. NNW winds ruin it, and Tuesday has a messy 7ft NW windswell with a poor 6-second period.

Wednesday and Thursday, 16th and 17th, are clean-looking with 6-7ft SW swells, but wind cranks up to 22-31 mph from the SE. Hard to paddle, not worth the struggle.

Now, Saturday morning, 19th September – that’s a stunner. We’ve got 8ft SW swell, a long 14-second period, combined energy of 2156, and a light 6 mph offshore ESE breeze. Clean, powerful, and inviting for those who can handle it.

Sunday the 20th is smaller – 4ft – but the wind is glassy, dead calm. Perfect for a longboard session with no chop.

Monday 21st brings a tiny 3ft WSW swell with a very long 17-second period. Clean cross-off wind keeps it rideable, but it might be a bit straight.

From Tuesday 22nd, wind picks up again. Wednesday 23rd afternoon sees 10ft of swell with 37 mph offshore winds – for the fearless only.

The tail end on 27th September shows 5ft of SW swell with an 18-second period, but light cross-onshore wind – lined up but bumpy.

Best bets: Sunday 13th morning and Saturday 19th morning. Don’t sleep on those.

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.
