The Lowdown
Alright, Rusty here, let's chew the fat on what Boneyards is serving up over the next 16 days.
Listen up, we’re looking at a solid run of consistent southwest groundswell at Boneyards, but the wind is going to be the deciding factor. This isn't a session for learners – the swell sits above 5ft for most of this run, and for a good stretch, it’s well over 8ft, so leave it for the experienced crew. The swell direction is exactly what this sandbar is looking for: west-south-west.
The week kicks off with a good pulse hitting on Tuesday, September 1st. Morning shows a 7ft west-south-west swell with a very long 15-second period and a light cross-offshore breeze. Wave energy is pumping strong. It's a solid start. The afternoon stays clean, just a bit more breeze, keeping it rideable.
Wednesday the 2nd sees the swell bumping to 8ft with a 13-second period, but the wind cranks to 30 km/h. It stays cross-off, so it’s clean, but that’s serious juice and a lot of push. This is expert territory, no doubt. Thursday the 3rd is a total loss – howling cross winds and lumpy mess.
Now, the real standout. Friday the 4th of September. The swell jumps to a massive 13ft, west-south-west, with a 16-second period in the afternoon. That's a very long period groundswell, and with the moderate cross-offshore breeze, it's going to be clean. Energy readings are through the roof. This is heavy, powerful surf for experts only at a sandbar, but the quality is undeniable. Saturday the 5th is a total washout with near gale-force winds.
The second week starts to mellow. Monday the 7th of September is the pick of the second week. Morning conditions are *glassy*, with a glassy 5 km/h westerly wind and a 10ft, 16-second swell. That’s a dream combo for an experienced surfer. Energy is very strong. The afternoon stays clean and light. The rest of the week holds fun, clean 8ft to 11ft swell, but the wind is a bit stronger in the cross-off position, so it’s not as perfect as that Monday morning.
Toward the end of the run, around September 15th, the swell backs right off to about 6ft, but the period stays long at 14 seconds. Energy drops to moderate levels. It’s clean with light east-southeast winds, so it’ll be a more manageable, fun-sized wave for a session, but nothing compared to the big stuff earlier.
Crowds can be a thing here sometimes, especially when it’s this consistent, but on a big day like Friday the 4th, that’ll thin the pack right out to just the crew who can handle it. The water temp is about average for this time of year, nothing unusual there.
So, for the best on offer: without a question, Friday the 4th of September for the sheer size and power, but Monday the 7th of September for the glassy perfection.
Rusty out.

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.
