The Lowdown
Alright, folks, Rusty here. Let’s cut through the noise and look at what Boneyards has on offer for the next couple of weeks. It’s a bit of a mixed bag, a tale of two halves really, so let’s get into it.
We kick things off this Sunday with a pulse of southwest groundswell pushing 12ft. The energy is strong, with a reading of 6357. But don’t get too excited just yet. It’s coming with a strong SSE breeze, slapping the surface into a clean but bumpy cross-off. The water is a bit colder than normal for this time of year at 58°F, so you’ll want the rubber. It’s rideable, but that wind is making it a bit of a battle.
Monday sees the swell ease to 8ft, but the wind swings more easterly and strengthens. It’s cross-off, which is okay for shape, but strong enough to put some real lumps on it. The energy drops to 1591, and the whole thing just loses a bit of its appeal. The scores are low for a reason.
Tuesday settles things down. The swell drops to a cleaner 6ft from the SSW, with a longer 12-second period. We get a proper offshore E wind at 16 mph in the morning, which cleans things up nicely. This is when the surf starts to look better, a genuine bright spot in the forecast.
The standout window, though, is Wednesday and Thursday. This is where the forecast gets really interesting. Wednesday morning, we’ve got 6ft of SW swell with an 18-second period. The combined energy is a solid 2471. That’s proper groundswell. The wind goes light and variable, almost glassy cross-off conditions. This is clean, lined-up, and set for an excellent session for those who know what they’re doing.
Thursday builds on it. The swell bumps to 8ft, still from the SW, with a long 18-second pulse. The energy reading jumps to 3999. With a light NE breeze, this is shaping up to be the pick of the bunch. This is the one to circle. Over 8ft, it’s pushing into expert territory, but for anyone who charges, this is going to be special. It’s a standout, no two ways about it.
Friday is still decent, 6ft with a 15-second period, but the wind starts to mess with things, going a bit cross. We get a good window on Friday arvo with a light offshore that cleans it back up.
The weekend takes a turn for the worse. Saturday and Sunday see the swell drop, but more importantly, the wind goes onshore from the north and northwest. Saturday morning is a write-off, with a moderate cross-onshore making things choppy. Sunday looks similar, with a bit less wind but still onshore. This stretch is looking poor.
Monday the 17th sees a size bump back up to 7ft, and then 10ft in the arvo, but with that cross-onshore wind, it’s going to be a messy, blown-out mess. For a break like this, with a cross-onshore and that much swell, it honestly looks more interesting for the kite crew than for us paddle surfers.
Tuesday the 18th brings a new swell, 12ft again, but this time from the south. The wind swings to a cross-off, cleaning it up a bit. It’s big and raw, but that wind direction will make it more manageable. The energy is up at 4873, so there’s plenty of push.
Then we hit a lull. Wednesday the 19th and Thursday the 20th are small, with the wind being the main feature. Friday the 21st is where it all kicks off again. We see the swell jump back to 12ft, and then 13ft in the afternoon, from the southwest. The wind goes light, and the energy readings are strong again. This looks like another excellent window for experienced surfers. It’s over a week out, so treat it with a bit of caution, but the signs are promising.
The following weekend looks a bit mixed. Saturday the 22nd has a bit of size but a cross-onshore wind. Sunday the 23rd cleans up with a light offshore, bringing some nice, clean 5ft to 6ft surf with a long period.
Finally, Monday the 24th looks like it could be a big finish, with 10ft of swell and a 16-second period. But that north wind is forecast to put a chop on it.
So, to sum it up: the surf to chase is Thursday the 13th, with that perfect combo of size, light wind, and long-period groundswell. The following Friday the 21st is another one to watch closely, but it’s further out. There are a few clean windows in between, but those two are the standouts. The stretch over the weekend of the 15th and 16th is best spent doing something else.
This is Rusty, signing off.

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.
