The Lowdown
Alright, let’s get into it. The next couple of weeks are a mixed bag, but there are a few windows where it’s going to be worth paddling out at Boneyards. This is a reef setup, and it’s a fickle one, often inconsistent, but when it lines up, it’s a proper wave. The water’s sitting at 59°F, which is a bit colder than usual for this time of year, so don’t forget the hood.
The first real chance to get wet is Wednesday afternoon, but honestly, it’s pretty marginal. We’ve got a clean 4ft southwest swell, but it’s coming in with a cross-off breeze, so the surface will be okay. The energy is weak, so you’ll be scratching around for the odd one. It’s not really worth paddling out for unless you’re desperate.
Thursday morning is a different story. The swell jumps up to 8ft, and the southwest direction is right in the pocket for this spot. It’s still cross-off, but cleaner. This is the first real highlight. The afternoon backs off a touch to 8ft but is still workable. If you can, get out there in the morning.
Friday is a downgrade. The swell drops a bit, and the wind picks up, especially in the afternoon when it gets to a near gale. It’s going to be messy and blown out. Maybe a quick look in the morning, but I’d give it a miss.
Saturday is interesting. The swell is back up around 7ft to 8ft with a good long period. The wind is offshore, but it’s strong, which makes it a battle to get out the back. It’s clean, but those strong offshores will be holding you up. This one’s for the experienced crew.
Now, Sunday morning is where it’s at. This is the standout of the first week. The wind drops to glassy, and we’ve got a clean 7ft southwest swell with a long period. The conditions are going to be perfect for Boneyards. The surface will be like a lake. It’s going to be a proper session for the better surfers. The afternoon stays clean with a light breeze, and the swell drops slightly to 6ft.
Monday kills it. The wind swings onshore and gets strong, and the swell turns into a mess. There’s a 8ft NNW windswell with a short period, which is just lumpy junk. Stay on land. Tuesday is more of the same, with strong onshore winds and messy conditions.
The next real window opens up on the 16th, which is a Wednesday. This looks like the biggest swell of the whole period. We’re talking 12ft of southwest swell, and the energy is massive. The wind is cross-off and fresh, so it’ll be clean, but this is big. This is for experts only. Anyone else should be nowhere near it. The afternoon backs down to 10ft, still huge.
The days after that ease off, and the 18th is another nice looking day. A clean 8ft to 8ft southwest swell, with a light offshore breeze in the morning. The energy is good, and it looks like the best of the second week. This one’s a go.
The 19th is still fun, but the wind is a bit stronger. The 20th morning is back to glassy, with a 7ft swell, but the afternoon turns a bit onshore and choppy.
After that, it fades out. The 21st through the 24th are poor, with small, onshore slop. There’s a day on the 23rd with a strong offshore, but the swell is too small to make it worth the paddle.
So, to wrap it up: your best bets are Sunday the 13th for the cleanest conditions, and Wednesday the 16th for the biggest, most powerful waves, if you’re a charger. The 18th is also a solid pick for a smaller, more manageable session. The rest is mostly waiting for the next pulse.

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.
