Alright, Rusty here. Let’s break down what’s coming for Boneyards. It’s a reef break, and it’s inconsistent, so patience is the name of the game.
Monday the 13th and Tuesday the 14th are a bust. Tiny 3 ft swell from the south-southwest and some lousy cross-onshore winds. Not even worth thinking about.
The first bit of life shows up Wednesday the 15th. Morning sees a 5 ft south-west groundswell with a long 17 second period, building to a solid 10 ft in the afternoon (4215 combined energy). Wind is light but cross-onshore. It’ll be messy for a reef that size.
Friday the 17th brings the first clean session. A moderate offshore breeze from the southeast, with a 7 ft south-west swell (1048 energy). That’s a proper clean window for experienced surfers.
Now, the one to circle. Tuesday the 21st of July, morning session. We’ve got a 10 ft south-southwest groundswell, a very long 16 second period, combined energy of 4870, and a clean, light cross-off breeze. Heavy, powerful, lined-up reef waves. Experts only at that size.
Then, Thursday the 23rd afternoon. Glassy. Zero wind. Still holding at a massive 13 ft south-west groundswell (5686 energy). This is the exceptional day – dead calm, clean, and heavy. If you can handle that kind of size, that’s your window.
Saturday the 25th also looks good, with a clean offshore breeze and a 8 ft to 10 ft south-west groundswell (up to 3906 energy). Another solid day for the experienced.
The rest of the run is a bit blown out or choppy, with the swell fading through the 27th and 28th.
Bottom line: Boneyards is inconsistent, but when it goes, it goes big. The standouts are the morning of Tuesday the 21st and the glassy afternoon of Thursday the 23rd. Both are for expert surfers only.
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.
