The Lowdown
Alright, this is Rusty, and I’m looking straight at the charts for our local patch. We’ve got a solid window of surf coming up, but you’ve gotta pick your moments. The water is sitting at 58°F, which is a bit colder than usual for this time of year, so grab a thicker suit.
The first real action is Thursday morning, September 3rd at Boneyards (reef). We’re looking at a clean 6ft swell from the WSW with a 13-second period, and a moderate offshore breeze. The water is a bit chilly, but the waves are packing some serious punch with a combined energy of 1410, and it’s proper surf for experienced surfers. The wind is going to make it glassy, and that swell direction is straight from the west, which is exactly what this spot likes. It’s a standout session for the week.
The wind gets nasty from Thursday afternoon all the way through Saturday, with near gale to gale force winds. The swell drops, and the conditions are blown out. You’ll be better off staying on the beach.
Sunday, September 6th is the next big call. The morning brings a beautiful 8ft SW groundswell with a very long 18-second period. The energy is massive at 3310, and we’ve got a moderate offshore breeze. This is the kind of long-period swell that will line up perfectly at a reef like Boneyards, offering long, powerful walls. It’s top-tier, top-to-bottom surfing for anyone who knows what they’re doing. The afternoon holds at 7ft with a clean cross-offshore breeze.
Monday and Tuesday look a bit messy with cross-onshore winds and question marks, but on Tuesday morning, September 8th, the conditions turn glassy. The swell is a smaller 5ft from the SW, but with a 12-second period and zero wind, it’ll be a fun, clean session for intermediate surfers. The energy is moderate at 678, but it’s a nice change of pace.
After a lull in the middle of the week, we get a pulse on Sunday, September 13th. The morning brings 7ft of SW groundswell with a 13-second period and a moderate offshore wind. The energy is back up to 1457, and it’s excellent for experienced surfers again. The wind stays strong on the backside of this one.
The final stand-out window is Tuesday, September 15th through Wednesday, September 16th. We’ve got solid SW groundswell in the 7ft to 8ft range with 14-15 second periods. The winds are clean cross-offshore, and the energy is well into the thousands (1336-2490). The waves will be big and powerful, best for the experts.
Then, a monster shows up on the long-range charts. Thursday, September 17th has a massive 12ft to 21ft WSW groundswell with a 17 to 19-second period. The energy is off the charts – 8895 in the morning, and a staggering 26745 in the afternoon. The wind is clean cross-offshore, but the swell is too big for this break. The forecast says it’s predicted to be too big. Friday, September 18th, is even bigger and totally blown out by near gale-force winds. That’s a one-way ticket to a washing machine.
Overall, the best on offer is Sunday morning, September 6th for the perfect combination of size, power, and offshore wind. The Thursday morning, September 3rd session is a close second for the clean, moderate swell. Get on it.
Rusty.

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.
