The Lowdown

G'day, Rusty here with a look at what the ocean's got cookin' for the next couple of weeks. Let's get into it.

The forecast opens up on Wednesday the 2nd of September with some solid, grunty swell running into Boneyards. We're looking at a swell height of 10ft from the southwest, with a long period of 13 seconds, pumping a massive amount of energy into the water (combined swell energy of 3471). The water temp is sitting at 58°, which is a touch colder than you'd normally expect for this time of year – about 3 degrees chillier, so don't forget the booties. The morning is looking clean with a light cross-offshore breeze, making for some excellent conditions, but this is strictly one for the experienced crew only. That size is over the 8ft mark, so if you're not feeling confident on a bigger day, sit this one out. The afternoon stays clean but gets a bit more wind.

Thursday the 3rd of September morning still has clean 6ft swell from the WSW at 13 seconds, and the wave energy (1218) is still solid. But by the afternoon, that wind cranks up to a near gale from the SE, smashing things up and making it a write-off. Friday the 4th and Saturday the 5th are completely blown out with gale-force and strong offshore winds respectively – the waves are small and messy. You could kite surf in that wind, but it's a no-go for paddling.

After a few days of junk, Sunday the 6th of September brings a stunner. The morning kicks off clean and glassy with a light offshore breeze and a big 7ft groundswell from the southwest. The period is a whopping 18 seconds, giving you a combined swell energy of 2528. That's a true groundswell with some serious push between sets. For an exposed reef like Boneyards, this long period means the waves will have lines and shape, though the long wait for sets will give you a chance to catch your breath. This is the standout of the week for the more experienced surfer.

Monday the 7th of September sees the winds turn onshore and choppy, so we can forget about it. Tuesday the 8th is a messy cross-onshore affair.

Wednesday the 9th of September, however, is a gem. The morning is absolutely glassy – no wind at all – with a clean 3ft swell from the SW at 13 seconds. That's a small but perfectly clean little wave, perfect for a cruisey session on a reef that can hold a bit of shape. Conditions are about as good as it gets, just small.

Thursday the 10th and Friday the 11th have moderate winds that create a bit of a cross-chop, so it's nothing to write home about. Saturday the 12th and Sunday the 13th are back to near-gale and fresh offshore winds that are too strong to paddle into.

A little whisper in the long-range forecast: Tuesday the 15th of September has a promising window with light offshore winds and 5-6ft swell from the WSW, with good energy (752-937). It looks very clean and fun for an intermediate.

Then, on Wednesday the 16th of September, the ocean is set to roar. The afternoon brings a massive 16ft groundswell from the SW with a period of 16 seconds and an enormous combined swell energy of 12557. Yes, you read that right. This is a big, powerful, and dangerous swell. The notes say it's marginal, probably due to tide, but the energy is off the charts. Thursday the 17th still has 12-10ft of leftover swell but the wind picks up strong, making it a bit of a blustery affair.

All in all, this window has two real highlights: the clean, powerful 7ft groundswell on Sunday the 6th of September and the absolute bomb of a swell on Wednesday the 16th of September for hardcore, experienced surfers only. Keep the glassy Wednesday the 9th of September in mind for a fun, uncrowded session on a smaller board.

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.
