The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.

Right off the bat, we’ve got a bit of a messy start. Saturday afternoon is a write-off with a near-gale offshore wind making it a nightmare to even get out there, so don’t bother. But hold onto your board shorts, because things turn around fast.

The real standout for the whole period is Sunday, September 6th morning. Boneyards is going to be firing. We’re talking a solid 8 ft swell from the SW, and with that long-period groundswell of 18 seconds, those waves are going to have some serious power and shape. The wind is a moderate offshore from the ESE, keeping the faces clean as a whistle. The combined energy is pumping at a very strong 3681. This is excellent surf for experienced surfers – if you’re a beginner, this is too much juice. Crowds are possible here, so get in early.

Now, if you miss that Sunday morning, the afternoon on the same day is still a solid option with 7 ft waves and that same clean offshore wind, though the energy dips a little. Monday morning (September 7th) sees the wind shift to a light cross-onshore, which introduces some bump, but the 7 ft swell is still hanging around, albeit with a shorter period, so it’s not as good.

We have a few days of mediocre to small surf after that, with waves dropping to around 3 ft and despite clean conditions, the energy is weak (320-350). The water temp is sitting at 58°, which is a bit colder than usual for this time of year.

The next big one to keep an eye on is Thursday, September 10th morning. The swell bumps back up to a solid 10 ft from the SW with a 15-second period, pushing very strong energy at 3816. The wind is a moderate offshore, keeping it clean. This is strictly for the experts at 10 ft, and the crowds will likely be out. The afternoon is similar but with a stronger breeze.

After that, things get a bit wild and messy. We get another big pulse on September 12th with 10 ft SW swell and very strong energy (4493), but the offshore wind is a strong breeze, making it hard work to paddle. Cloudy skies and lumpy conditions return on September 15th with 10 ft waves but a fresh cross-onshore ruining the quality.

The final major standout is a serious one. Wednesday, September 16th brings a massive 15 ft swell from the SW. The morning has a 15-second period registering a huge combined energy of 8491, and the afternoon isn't far behind at 7449. The wind is a fresh offshore, so it will be clean, but at 15 ft, this is for elite, experienced chargers only. The afternoon is similar.

After that, we wind down with a nice glassy morning on Saturday, September 19th. The swell drops to 6 ft from the SW, but with zero wind and a glassy surface, it’ll be a beautiful, clean session for experienced surfers, with moderate energy of 1044. The conditions on Sunday, September 20th, are still clean with a 7 ft swell, but the wind is slightly stronger.

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.
