The Lowdown
Right now, the ocean’s got some serious muscle behind it, but it’s gonna take a bit of patience to line up the good windows. The standout window is Sunday the 22nd – that’s the one you want to circle. But let’s break it down day by day, because there’s a fair bit of chop and wind to sift through first.
This Morning (Sunday 13th) – Boneyards is looking pretty special. Solid 6.9ft of southwest groundswell, with a long 14-second period, and the east wind is holding it together as a clean cross-off. Water’s sitting at 58.5°, which is about a degree colder than usual for this time of year – you’ll feel that nip on the paddle out. The energy is strong, coming in at 1665. This is proper experienced-surfer territory; the reef’s handling the swell beautifully. By this afternoon it goes glassy, slight rain, 5.9ft and still that long SW swell – honestly, it’s as good as it gets right now. This is the pick of the opening day.
Monday 14th – The wind swings around to the NNW and it’s onshore, 30-35 km/h. That’s junking it up. Swell drops to 4.3ft, period still decent at 12 seconds, but the surface is lumpy and messy. Not worth paddling out unless you’re desperate for a grovel. Skip it.
Tuesday 15th – Similar story, NNW wind, 35 km/h, cross-on. The morning’s tiny at 2.3ft, but the afternoon bumps up to 5.6ft with a 16-second period. The energy jumps to 1880, but that wind ruins it. It’s all over the place. Leave it.
Wednesday 16th – Now we’re talking about a shift. The wind swings southeast, 40 km/h, but it’s cross-off, so it’s actually cleaning it up. Swell is 6.6ft in the morning from the WSW, 13 seconds. The energy’s strong at 2500. It’s clean, but the forecast calls it marginal – tide’s probably messing with the reef. The afternoon drops to 5.2ft, still clean. This is a “watch it” day – might be workable, but not the standout.
Thursday 17th – Morning is your best bet: southeast offshore wind at 35 km/h, 6.2ft

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.
