The Lowdown
Alright folks, Rusty here. Let's have a look at what Boneyards has in store for us over the next couple of weeks. It's a bit of a slow start, but there are some serious pulses lined up if you're willing to wait.
The water is sitting at 59°, which is about 1° cooler than usual for this time of year. Nothing too wild, just a touch on the chilly side, so you might want that extra layer.
The first few days are pretty average. Thursday the 27th has some waist-high 5ft swell from the south, but that cross-on wind is making it a bit messy. The energy is moderate (863), but it's not calling my name. Friday the 28th afternoon is where things start to look up. We get a clean 4ft swell from the WSW with a 14-second period, and the wind swings cross-off. That's a decent window, and the energy is still moderate (779). Saturday the 29th morning sees a bigger 6ft WSW swell with a long 15-second period, and the energy jumps to strong (1145). The wind is just light cross-on, so it's worth a look, but that afternoon turns into a write-off with a fresh 22 mph cross-breeze and rain.
Sunday the 30th is a solid day. Clean conditions with a 8ft swell from the WSW in the morning and 8ft in the afternoon, both with cross-off winds. The energy is strong (1828 / 1536), but this is getting into the size range where it's better for the more experienced crew. Not a beginner's day.
We hit a bit of a lull Monday the 31st and Tuesday the 1st of September, with the wind turning onshore and the swell dropping. Skip those days.
Now, here's the standout. Wednesday morning the 2nd of September. Glassy conditions, a 13ft swell from the southwest with a 14-second period, and the energy is pumping through the roof at 7276. This is exceptional surf, but it's only for the experts. That's a big, powerful groundswell, and it's going to be a handful. The wind is glassy early, which is a massive bonus.
The rest of the first week of September stays big, with 12ft to 13ft swells, but the wind is strong and cross-off, keeping it clean but challenging. Thursday the 3rd and Friday the 4th are still in the expert-only zone with strong energy (3371 to 2487).
We tail off significantly after that. Saturday the 5th of September morning is a tiny 1.0ft leftover swell with a 23-second period (very long period, but next to no size). The energy is weak (201). The afternoon picks up a bit to 5ft, and Sunday the 6th is clean and glassy with a 4ft, 16-second period swell from the SW. That's a nice, smaller window for the intermediate crew.
From Monday the 7th of September through to Wednesday the 9th, it's flat and poor. Swells are under 3ft, winds are messy, and the energy is weak (down to 129). A real gap in the action.
Then we see a return of the long-range potential. Thursday the 10th of September brings a 5ft to 6ft WSW swell with a 16-second period, but the wind is a strong 25 mph cross-off. The energy is strong (1437 / 1507), but it's going to be a battle.
Finally, Friday the 11th of September is another big one. A 13ft southwest swell with a 13-second period, and the energy is massive (5183). The wind is offshore at 25 mph, which is clean but will make paddling out extremely hard. This is a pure expert session, and it's a long way off, so keep an eye on it.
So, to sum it up: the clear standout is Wednesday morning, the 2nd of September. If you're an expert, that glassy 13ft groundswell is the one to circle. For the rest of us, the best bet is Sunday the 30th of August with the 8ft clean swell, or the smaller, glassy session on Sunday the 6th of September.
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.
