The Lowdown
Alright, Rusty here, let's get into it. It's a bit of a slow cooker, this run. We've got some serious size coming, but it’s gonna take a few days to set up.
The next week starts quiet, then a building trend leads to some proper, solid south-west groundswell. The real standout, the one that's got my heart racing, is a big swell on Thursday the 3rd of September. Before we get there, Wednesday the 26th of August looks like the pick of the early week for quality surfing.
Boneyards is the only spot on offer. It's a reef break that needs everything to line up just right, being inconsistent and best for intermediate crew.
West swell is what you want feeding into this reef.
The water temp is sitting at 59°F, which is about 2°F colder than normal for this time of year. It’s not a freak cold snap, but you'll feel it.
Let’s run through the dates.
The first real surf window is Tuesday the 25th of August. We’ve got a solid 8ft to 7ft west-south-west swell with a long 14 second period. That’s proper groundswell energy, with a combined energy of 2549 on Tuesday morning. However, the wind is a punishing 25 mph from the southeast, which is offshore at Boneyards. While that keeps the surface clean, that's a scary paddle-out. The wave state is described as "hard to paddle into." It’s not a beginner day and the conditions are marginal. I’d skip this one.
Wednesday the 26th of August is where we get the best early surf. The swell drops to a very surfable 4ft west-south-west, still with a good 13 to 12 second period. The wind goes light offshore from the east-southeast, only 12 mph. That is a sweet spot. Clean, moderate energy (1149 to 1140), perfect for an intermediate session. This is a green light.
Thursday the 27th turns onshore and messy, so give it a miss.
Friday the 28th of August comes back clean. The wind is light, the swell is a fun 4ft to 4ft from the south and west-south-west. The energy is moderate (642 to 869). It's a good, clean low-key day.
The weekend gets lumpy again. Saturday the 29th has onshore wind and poor conditions.
Now we get into a stretch of solid, powerful swell. From Sunday the 30th of August through Tuesday the 1st of September, we see 7ft to 8ft west-south-west groundswell, with energy values climbing into the thousands (2049, 1857, 1475). The wind is mostly cross-offshore, keeping the faces clean. This is solid intermediate-to-expert territory. It's above 5ft, so beginners will be out of their depth, and the period is long (11 to 13 seconds), giving it punch.
The standout, the one to circle on your calendar, is Thursday the 3rd of September. Brace yourself for a massive 15ft south swell, with a combined energy of 8667. Morning wind is a strong offshore from the southeast, cleaning it right up. By afternoon the wind drops to a light 6 mph cross-offshore breeze. That’s phenomenal. The forecast score confirms it’s an exceptional setup for expert surfers only. This is the hurricane of the run. If you have the skills, this is the session to be had.
After that big pulse, Friday the 4th of September fades to a dribble of 2ft to 3ft. Not worth a paddle.
But then we get a very long period (16 second) groundswell late in the run on Saturday the 5th of September. 5ft to 6ft from the south-southwest, with a 15 to 16 second period. That's a very long period. The wind is light offshore or cross-offshore. The energy is strong (1094 to 1806). This will produce long, clean, powerful lines—classic reef-swell surfing. Good for intermediates and above.
The run dries up on the 7th, 8th and 9th of September, with small, weak pulses and strong winds that won't deliver anything good until a late 4ft west-south-west swell on the 9th, but the wind will be strong.
Overall, the two standouts are Wednesday morning the 26th of August for a clean, fun session, and the absolute heavy-hitter session on Thursday afternoon the 3rd of September for the experts.

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.
