The Lowdown
Alright, Rusty here again, putting it in feet and miles for you.
Let's talk Boneyards. This reef is an inconsistent spot, so it's not always breaking, but when it does, it can be a classic.
We start on Thursday, the 27th of August. Not much happening. There's about 5ft of S swell, but the wind is cross-on, and the conditions are choppy and marginal. Best to stay home. Water temp is about normal for this time of year.
Friday the 28th is the first real highlight. The morning is glassy, dead calm, with a 4ft S swell. The energy is moderate (642). It's clean, small, and just right for a fun, easy session. This is the pick of the first few days.
Saturday the 29th: swell picks up to 5ft to 6ft from the WSW, but the wind is cross or onshore, and it gets lumpy in the afternoon. The energy is strong (1437), but the conditions are messy.
Sunday the 30th is a standout for experienced surfers. You've got 8ft of clean WSW swell, cross-off wind, and excellent conditions. The energy is very strong at 1990. This is a proper reef session, but only for those with the skills.
Monday the 31st drops off, onshore wind, messy, with 6ft to 7ft of swell. Not worth it.
Tuesday the 1st of September: forget it. 10ft of SW swell, fresh cross-onshore, lumpy, and dangerous.
Now, Wednesday the 2nd of September is a long-range promise for the experts. Swell is 13ft to 15ft from the WSW, with insane energy (6939 to 13051). The wind is cross-off and clean. It's a monster session if it comes together, but it's far out, so keep checking.
Then from Thursday the 3rd of September, the bottom falls out. The swell drops, gale-force winds kick in, and the scores are all zeros. This dry spell runs through the 4th, 5th, 6th, 7th, 8th, 9th, and 10th. There's a tiny bump on the 5th and 6th, but with poor conditions, it's a no-go.
The 9th and 10th of September show some 7ft of short-period windswell from the NW, but it's choppy and cross-on. No good.
The outlook ends on the 11th of September with a tiny, clean 3ft swell and almost no energy. A real flop.
So, your best bets are Friday morning the 28th for a glassy small session, and Sunday the 30th for the bigger, clean, expert-level surf. The huge Wednesday the 2nd is a long shot for the brave. The rest is a bust.
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.
