The Lowdown
G’day, Rusty here. We’ve got a 16-day look at Boneyards, a reef setup that’s a real gem when the stars align, but it’s inconsistent and only really fires on its best days. The water temp is sitting about average for this time of year, no big anomaly to report, so grab a normal spring suit.
The week starts off grim. Saturday the 5th is a write-off—strong offshore winds are cranking at 28 mph, making it clean as a whistle but near impossible to paddle into. The swell’s got weak energy (236) and it’s just not happening. The afternoon is similar, with a tiny 1 ft, long-period swell that’s too clean for its own good.
Then things switch hard. Sunday the 6th is the standout of the whole outlook. It’s firing. A solid 8 ft swell out of the SW, with moderate offshore winds (12 mph) keeping it clean and lined up. The combined energy is pumping (3681), and this is for experienced surfers only—over 8 ft is big stuff. This is the day to be in the water, no question. The afternoon holds up too with 7 ft and still clean.
Monday the 7th drops off a cliff. Light cross-onshore winds, 7 ft to 7 ft swell, but the quality is marginal with soft energy (1339-1549). Tuesday the 8th is glassy in the morning, but the swell drops to 3 ft, so it’s clean and small—a fun one for a longboard if you’re keen, but not the biggest score.
Wednesday the 9th is poor, with moderate cross-off winds and small swell. Thursday the 10th looks promising on paper with 8 ft SW swell, but fresh cross-off winds and marginal conditions mean it’s not as good as it could be. Same story into Friday the 11th, with the afternoon turning into a total mess—34 mph winds and a short-period 10 ft swell that’s just nasty.
Saturday the 12th brings another highlight. Glassy morning, 5 ft SW swell with long period (14 seconds) and strong energy (1446)—this is clean and punchy, perfect for intermediates. The afternoon gets a bit choppy with cross-onshore winds, but the morning session is a solid pick.
From Sunday the 13th through to the 15th, it’s mostly cross-onshore and poor. The 15th is a stormy mess with 10 ft to 12 ft and 25 mph winds—don’t bother.
Wednesday the 16th and Thursday the 17th see big, clean but windy conditions. Strong offshore winds on the 17th (28-34 mph) make for clean faces but brutal paddling. The energy is huge (4578-4754), so this is for experts only, and even then it’s a battle.
The final stretch looks solid again. Friday the 18th has a sweet 6 ft W swell, light offshore winds, and clean conditions—this is the second standout, a proper gem for experienced surfers. Saturday the 19th morning is glassy with a 7 ft S swell and long period (11 seconds), so it’s got power and shape—another top call for the experienced crew. The afternoon and Sunday the 20th fade out with poor conditions and rain squalls.
Bottom line: Sunday the 6th and Saturday the 12th morning are your best bets. The 6th is the big one for experts, the 12th is glassy and clean for a more relaxed session. Keep an eye on the 18th and 19th mornings too, they’re promising. Boneyards is inconsistent, so you gotta pick your 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.
