The Lowdown
Alright folks, Rusty here. Let’s have a good look at what’s coming our way for the next couple of weeks.
The forecast is a bit of a slow burner, but it builds to a serious climax later on. The first few days have some surf, but the real standout is a long way off, so keep that in mind.
For the first proper run of waves, we’re looking at Tuesday the 21st of July at Boneyards. This is a reef break, and it’s inconsistent, so don’t expect non-stop action, but when it comes, it’ll be worth it. We’ve got a solid 8 ft swell from the SSW, with a very long period of 14 seconds. That’s proper groundswell energy. The wind is glassy in the morning, which is a massive positive for clean conditions. The combined energy is pumping at 2615 (moderate wave energy). This is going to be a big, powerful wave, and at over 8 ft, it’s only for experienced surfers. The water temp is about average for the time of year, nothing unusual there.
The glassy conditions hold into the afternoon, but the wind picks up to a cross-offshore breeze, keeping things clean. The swell jumps to 10 ft from the SW with a 13-second period, and the energy is even higher at 2816 (moderate wave energy). Still excellent for the experienced crew.
Moving into Wednesday the 22nd, the swell drops a bit. Morning sees a 7 ft SW swell with a 12-second period, but the wind is onshore and light, making the surf quality a bit unknown. It’s a marginal call. The afternoon gets worse with a stronger cross-onshore wind and choppy conditions, so I’d sit that out.
Thursday the 23rd is a write-off. Strong onshore winds and rain make for poor surf. Friday the 24th, however, is a cracker. We’ve got a 12 ft SW swell with a 14-second period and a clean offshore wind in the morning. The combined energy is massive at 4832 (strong wave energy). This is excellent for experts, but hold on, because the wind is light and offshore, so it’ll be clean. The afternoon stays clean with a cross-offshore breeze, but the swell dips to 10 ft.
Saturday the 25th keeps the swell going with a 7 ft SW groundswell and a moderate offshore wind in the morning, keeping it clean. The energy is 2092 (moderate wave energy). Still good for the experienced.
Sunday the 26th offers a glassy morning with a 6 ft SW swell, but it’s inconsistent. The afternoon turns onshore, so get it early.
Monday the 27th has a glassy morning again with a 7 ft SW swell. The afternoon, however, is a no-go with a strong breeze and messy conditions.
The rest of the first week and into the second week is a mixed bag. Tuesday the 28th has a moderate offshore wind, but the swell is dropping. Wednesday the 29th is worth a look with a 8 ft SW swell and a clean offshore wind, but it’s not a standout.
Now, there is a long gap of poor conditions from the 30th of July all the way through to the 2nd of August. Strong winds, rain, and dropping swell mean you should probably find something else to do.
But then, hold onto your board. Monday the 3rd of August is the true standout of the entire forecast. Boneyards wakes up with a monster. The morning is absolutely glassy – calm wind, dead flat water – and a 12 ft WSW swell with a very long 16-second period. The combined energy is a massive 6733 (strong wave energy). That’s exceptional for expert surfers. The afternoon is even bigger: a 15 ft WSW swell, 15-second period, and a clean cross-offshore breeze. The energy hits 8439 (strong wave energy). This is a serious, big-wave day. That long period at a reef break like this is a recipe for perfection, but it’s only for the most experienced. The water temp is still about average.
Tuesday the 4th of August sees the swell peak at 16 ft, but the wind turns cross-onshore and choppy, ruining what could have been a legendary day. So the window is narrow.
So, to sum it up: the best bet is the massive swell on Monday the 3rd of August if you’re an expert. For the rest of us, the clean, glassy days on the 21st and 24th of July are your best shots. Don’t sleep on Monday the 3rd, but be ready for a serious session.
Stay salty,
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.
