The Lowdown
Alright folks, Rusty here. Let’s talk about what’s cooking at Boneyards. This reef setup is our only game in town for the next couple of weeks, and it’s going to be a real mixed bag.
Right now, the swell is running, but the conditions are a bit of a battle. Thursday morning kicks things off with a clean 6ft WSW swell, period at 13 seconds. The wind is a light cross-off, so the paddle out won’t be a fight, but the wave comment says the tide might be tricky. The energy is pumping at 1674, so there’s definitely power in the water. That afternoon, the wind cranks up to 31 mph, and it’s game over for the session.
We’ve got a long, ugly stretch from Friday into the middle of next week. Friday morning, the wind is a screaming 34 mph offshore, making it nearly impossible to paddle into anything. That theme of strong, clean but brutal offshore winds hangs around through Saturday, leaving the surf quality poor. The swell drops right down, too.
The Standout – Sunday, 6th September
Sunday morning is the real deal. We’ve got a 8ft SW groundswell with a very long period of 18 seconds pushing in. The combined energy is a massive 4201, meaning this is a powerful, deep-water swell. The wind is a gentle offshore breeze from the ESE, so the faces will be clean and lined up. This is big, solid surf, though—over 8ft of proper groundswell—so it’s strictly for experts. The period is so long that it might reel off a bit too straight at a beach break, but Boneyards is a reef, so it should handle that beautifully. The afternoon stays clean with a 7ft swell and a light breeze, but the energy drops to 1995. This is the best session on offer.
Monday the 7th sees a shift in wind, coming from the NNW as a cross-onshore, ruining the shapes. The waves are still overhead at 6ft to 7ft, but it’s choppy and messy. The rest of the first week is a write-off, with marginal conditions and wind that keeps switching.
Another Look – Sunday, 13th September
After a gap of poor conditions, next Sunday, the 13th, looks promising again. The morning is a clean 4ft SW swell with a light cross-off breeze and manageable energy of 605. The afternoon is the real standout for that week: a 8ft SSW swell, period of 13 seconds, and a light southerly cross-off wind. The energy is a solid 2150, and the surf is rated excellent for experienced surfers. The water temperature is about average for the time of year, so no wetsuit surprises.
The following week gets messy again. Monday the 14th is a chop-fest, and by Tuesday the 15th, the swell drops to under 3ft. That Tuesday afternoon is a rare treat, though: the wind goes glassy, and the 3ft SW swell will be clean and fun for a log, but it’s a small window.
The very end of the outlook, around the 16th and 17th, shows a big spike in energy with 13ft and 12ft swells, but the wind is howling again. Friday the 18th morning wraps it up with a clean 8ft SSW swell, moderate offshore wind, and a score of 4 out of 10 for experts. The energy is 1307, so it’s got some punch, but don’t sleep on the wind.
In short, the first week is all about that Sunday morning blowout. The second week has a couple of windows, but the standout is the afternoon of the 13th. Boneyards is inconsistent, so when it’s on, you gotta go. Just remember, this is a reef, so don’t be a liability.
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.
