The Lowdown
Alright folks, Rusty here. Let's get into it.
We've got a classic setup on the cards at Boneyards, a reef break that can be a bit inconsistent but when it turns on, it's a real treat. The water temp is about average for this time of year, so a standard spring suit will do you fine.
The first real action kicks off on Tuesday morning, the 1st of September. We’re looking at a solid 10-foot SW groundswell with a long 13-second period, pumping a massive 3112 units of energy. The wind is light and cross from the SSW, so the lineup will have a bit of texture but it's rideable. This is big, powerful surf for experienced surfers only. The afternoon sees the swell bump up to 11.5 feet, but the wind swings more cross-on and it gets a bit choppy, so the morning is the call.
Wednesday the 2nd is the standout. The morning session is where it's at. The swell holds at 10 feet from the SW, still with a 13-second period, and the wind swings to a light S cross-off, making for clean, well-shaped waves. The energy is still massive at 3471. This is excellent surf for those who know what they're doing. The afternoon stays clean but the wind picks up a bit.
Thursday the 3rd is a solid pick for the experienced crew. The swell drops to a more manageable 6 feet from the WSW, still with a 13-second period. The wind is light and cross-off from the south, keeping things clean. The energy is still a strong 1622. We might see a few rain showers, but that won't ruin the surf. The afternoon is a write-off with a 55 km/h near-gale from the SE, don't even bother.
Friday the 4th through to Sunday the 13th of September is a long stretch of poor conditions. The wind is howling from the SE or ESE, often gale-force, making it near impossible to paddle out. The swell is small and weak. This is a total blank run. There's a little bump on Sunday the 6th with a 5-foot SW swell and a very long 15-second period, but the offshore wind is so strong it's a workout just to get out. The energy is 1390, but it's not worth the fight.
Monday the 7th offers a small window. The wind goes glassy in the morning with a light NE breeze, and there's a small 3-foot SSW groundswell. It's small, but clean. The afternoon is a bit better with a light cross-off, but still small.
Things get interesting again on the 16th of September. Wednesday morning the 16th shows a big pulse of 10-foot SW swell with a 13-second period and 3292 energy. The wind is a gentle cross-on from the NW, so it'll be a bit bumpy, but the size and power are there for a solid session. Mark it as promising but a long way off.
Best Bet: Wednesday morning, the 2nd of September at Boneyards. Big, clean, powerful SW groundswell with light offshore winds. It's for the experienced crew, but it's the standout of the window.

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.
