The Lowdown
Alright, rust and dust, let's talk about what's cookin' at Boneyards. This is a reef break, and it's an inconsistent one, so when it talks, you listen. It's an exposed spot that loves a good W swell.
Right off the bat, the water is a bit nippy for the time of year, sittin' at 58° with a water temp anomaly that's over two degrees colder than normal. It's a bit more of a wetsuit situation than a boardies affair.
The first real chance to get wet kicks off on Monday the 10th, but it's a tough one. We've got a solid 7ft swell from the south, but that wind is a strong SE breeze, and it's a cross-off. It's gonna be a battle to get out, and the conditions are questionable. The wave energy is massive, though, registering strong at 1626. The afternoon cleans up with a strong offshore, but the swell drops to 4ft and it's hard to paddle into. Not the best start.
Tuesday the 11th is a bit of a tease. The morning has a fresh offshore wind with a 6ft SSW swell, but it's still a mixed bag. The afternoon drops to a tiny 2ft, but the period is a massive 24 seconds. That's a super long period groundswell, which can be too straight for a reef, but the energy is still there. It's a waiting game.
Now, Wednesday the 12th is the first real standout. This is the session to circle. The morning is clean with a light ENE breeze, and we're looking at a solid 6ft SW swell with a 18-second period. The energy is huge, spiking to 2452. The afternoon is even better: a gentle offshore breeze from the SE, with a 7ft SW swell. This is clean, powerful, and built for experienced surfers. The crowd profile says "sometimes," so you might have a few mates out, but it's worth it.
Thursday the 13th gets a bit messy. The swell is up to 8ft, but the wind swings cross-shore, making it choppy. The energy is off the charts at 3797, but the quality drops. Friday the 14th is a mixed bag, but the afternoon is a hidden gem. The wind goes glassy with an easterly light air, and the 7ft WSW swell is clean. That's a good one.
Saturday the 15th and Sunday the 16th are a write-off with cross-onshore winds and lumpy conditions. The swell is there, but it's not worth the paddle.
Then we hit Monday the 17th. This is the big one. The morning has a 10ft WSW swell with a gentle offshore from the ESE. The energy is a massive 4462. The afternoon is even better: glassy conditions with a 10ft swell. This is a dream for experts, but if you're a beginner, 10ft is too big. This is the best session on offer.
After that, Tuesday the 18th and Wednesday the 19th are blown out. The wind is a near gale on Wednesday, making it impossible. Thursday the 20th is a return to form with a clean 7ft SW swell and a gentle offshore.
The last week gets a bit murky. There's a pulse on Saturday the 22nd with an 8ft WSW swell and a long period, but it's cross-shore, so not perfect. Sunday the 23rd has a 10ft swell in the afternoon with a clean cross-off wind, but it's a late call. The final days of the 24th and 25th are mostly chopped out or blown out.
So, the standout is without a doubt Monday the 17th with that glassy 10ft swell. For a close second, Wednesday the 12th is your best bet for that long, clean groundswell. This spot is inconsistent, so when it's on, you gotta be on it.

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.
