The Lowdown
Alright, mate, Rusty here. Let’s have a look at what’s on offer for the next couple of weeks.
First up, we’ve got Boneyards, a reef setup that’s inconsistent and only really works when everything lines up. The water temp is about average for this time of year, nothing weird going on there.
The action kicks off on Saturday the 15th of August with a solid 6ft WSW groundswell, period a nice long 14 seconds, and glassy conditions in the morning. The combined energy is sitting at 1261, which is strong. This is proper, clean surf for experienced surfers. The afternoon stays clean with a cross-off breeze and the swell bumps up to 7ft. Saturday is the standout of the early window.
Sunday the 16th takes a turn. The wind swings north and gets onshore, making a mess of things. The swell is still there, around 7ft to 8ft, but the quality is poor. That trend sticks through Monday and Tuesday as the wind stays cross or cross-off and the swell stays big, but the conditions are marginal at best. The energy is moderate to strong, but the wind is ruining it.
There is a bit of a dull patch mid-week, but things really clean up again on Friday the 21st of August. The morning is glassy, dead calm, with a 7ft SW swell at 11 seconds. The energy is strong at 1418 and the conditions are excellent for experienced surfers. That’s another good window.
Then on Saturday the 22nd, we get a massive but messy pulse. Swell hits 12ft to 13ft from the SW, with near gale-force winds. The energy is very strong at 4623 and 5492, but it’s blown out and dangerous. This is more for the kite crew than paddle surfers.
Sunday the 23rd cleans up again with a nice offshore breeze and a solid 10ft SW groundswell. The energy is still strong at 2978, and the conditions are excellent for experienced surfers. That’s a real gem.
The following week, from Monday the 24th, the swell drops off a bit. The 24th and 25th have cleaner conditions with smaller swell, but on Tuesday the 25th, we get a standout. The morning has an 8ft SW swell with a super long 17-second period, and the energy is very strong at 3455. The wind is light and cross-off, so it’s clean. The afternoon goes offshore and glassy with the same size swell and a 16-second period. This is another top-tier session, but remember, that long period groundswell can make beach breaks a bit too straight – at a reef like Boneyards, it’s going to be very good.
The rest of the week into the 30th is a mixed bag. The swell stays around 7ft to 10ft, but the wind is often onshore or strong, making conditions marginal. The energy is still moderate to strong, but you’ll need to pick your sessions carefully.
Overall, the best windows are Saturday the 15th, Friday the 21st, Sunday the 23rd, and Tuesday the 25th. That last one is the pick of the whole forecast, but it’s over a week out, so keep an eye on it.
Rusty.

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.
