The Lowdown

Alright, let’s get into it. It’s a tricky stretch ahead for our region, with Boneyards the only real game in town on the lineup. We’ve got a solid run of southwest groundswell pushing through, but the wind is going to be the main character in this story, and it’s not always going to play nice. Water temps are sitting around 59°, which is pretty much where we expect it to be for this time of year, nothing wild there.

The opening days are a bit of a wash. Thursday the 10th brings in some solid 8ft SW swell, but it’s messy and the tide looks iffy, so it’s not worth paddling out for much. The energy is pumping though, with combined energy at 2590. Friday the 11th, the wind swings offshore but it’s blowing a solid 25-28 mph, making it a real battle just to get out back. It’s clean, but it’s hard work, and the swell drops a touch.

The weekend starts to show some promise. Saturday the 12th has that strong offshore wind again, but the swell builds back to 8ft with a 16-second period from the SW. The energy is up there, 3525 on Saturday arvo, but that wind is still strong. Sunday the 13th is where it starts to get interesting. Lighter offshore winds, E/ESE around 12-15 mph, and the swell is a solid 7ft with 14-second period. This is the first real window of quality we get. It’s a reef break, exposed to that west swell, and it handles this kind of power well. The consistency is a bit inconsistent, so you might have to wait for the sets, but the ones that come through are worth it. This is the pick of the first week.

Then the wind turns ugly. Monday the 14th through Tuesday the 15th, we get strong cross-onshore winds from the north which will chop it all up. Even though there’s some serious size on Tuesday arvo with 6ft and 17-second period, it’s messy and not worth the hassle.

Things clean up big time for Wednesday the 16th. We’ve got a solid pulse of SW swell, hitting 12ft in the morning with clean cross-off winds. The energy is huge, 4864, a real sign of power. This is big, powerful surf, definitely for experienced crew only. It’s not a day for the faint-hearted.

Thursday the 17th offers a bit more manageable size, 7ft with fresh offshore winds, still clean. Then we get a standout morning on Friday the 18th, with only 5ft of SW swell but glassy conditions and light winds. For a reef break like this, that’s a magic window – clean, lined-up walls with very little wind. It’s a bit smaller, but the quality would be up there.

The second week gets a bit messy again. The following weekend swings back to bigger, cleaner but wind-affected surf, with SSE cross-off winds and solid 7-8ft SW swells. Then Monday the 21st brings another pulse of 12ft, with combined energy hitting 5369. That’s another big, powerful day. But the wind turns against us on Tuesday the 22nd, with a near gale from the SSE making it unpleasant.

After that, the run fades out. The last days of the period see the swell drop off, with a few smaller, cleaner days but nothing that really lights up the reef. There’s a brief window on the 25th with 7ft SW swell and moderate winds, but it looks like a bit of a letdown after the bigger weekend. Overall, the early call is that Sunday the 13th and Friday the 18th are your best bets for quality. The big days are for experts only.

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.
