The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’ve got a solid little run of clean, chunky swell on the way for the start of spring, but the first week is a bit of a mixed bag and the second week is a waiting game. The standout is going to be Tuesday morning, September 1st – that’s the one you don’t want to miss.
Things start off quiet on Monday, August 31st. Boneyards is showing a modest 7 ft from the WSW with a clean cross-off breeze in the morning. The water is a bit colder than normal at 58°, and the combined energy is moderate (1045). It’s surfable, but nothing to write home about.
Now, Tuesday morning, September 1st is the real deal. Boneyards is glassy with clear skies, a 10 ft SW swell and a thumping 13-second period. The combined energy is strong (2961). This is excellent, experienced surfer territory. It’s a reef break, and with that long period, it’s going to draw lines beautifully. The water is sitting at 58°, which is about two and a half degrees colder than usual for this time of year – a bit nippy, but worth it.
Wednesday, September 2nd, keeps the quality going. Both morning and afternoon sessions are clean with a light to gentle cross-off breeze and a solid 10 ft SW swell (13-second period). The energy is still strong (3471 and 3000). This is a multi-day run of quality.
We hit a wall from Thursday, September 3rd, right through to Sunday, September 6th. Strong winds – near gale force – and rain showers ruin the surface. The swell drops and the whole setup is a no-go for paddle surfing. The cross-off or offshore winds are just too strong, making it nearly impossible to paddle into. Kite surfers might have a look, but for us, it’s a hard pass.
Monday, September 7th, brings a bit of relief. The morning is clean with a light breeze, a 5 ft SSW swell with a 12-second period. The energy is moderate (668), and it’s a good, solid session. Still not top-tier, but a welcome return to form.
The rest of that week (September 8th through 10th) is small and background. A few clean windows with small glassy waves, but nothing that’s going to get the heart racing. The energy is weak (between 122 and 285).
Then, from Friday, September 11th, into the weekend, we get another pulse. The morning of the 11th has a 5 ft WSW swell with a clean offshore breeze, and the combined energy is moderate (547). The 12th is even better with an offshore breeze and a 6 ft WSW swell in the morning (851). Good, clean, fun waves.
The second week gets a bit messy. The 13th and 14th of September see a strong NNW wind and big, lumpy, poor-quality 10 ft and 8 ft swells. Not the time to paddle out. Tuesday, September 15th, looks cleaner again with a 6 ft SSW swell and a light offshore, but it’s a long way off and the energy is only moderate (727). Worth keeping an eye on, but nothing special.
So, the clear winner is Tuesday morning, September 1st. Glassy, strong, solid groundswell, and that reef will handle the period well. The crowd is listed as "sometimes," so get there early. Wednesday the 2nd is a very close second. The rest of the window is a story of clean windows punctuated by strong wind and poor conditions.
Rusty, signing off.

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.
