The Lowdown
Grab your board, this is shaping up to be a proper run at Boneyards (Boneyards). The water’s sitting at 58°F, which is a bit colder than normal for this time of year—so if you’re heading out, a hood ain’t a bad idea. The ocean’s got some serious grunt to it early on, with combined swell energy hitting 3681, which is strong stuff. It’s a reef break, inconsistent as always, so don’t expect a conveyor belt—but when it pulses, it’s worth the wait.
Sunday morning kicks things off with clean 8ft SW groundswell at 18 seconds—that’s proper long-period energy, sets rolling in with real authority. Offshore ESE breeze at 15 mph keeps it glassy. This is excellent surf for someone who knows what they’re doing; 8ft is pushing it for beginners. Sunday afternoon drops to 7ft at 16 seconds, still clean with a lighter SE offshore—good, but the morning is the pick. Crowds can show up here sometimes, so get in early.
Monday (7th) turns messy. The swell’s still there—7ft SW at 14 seconds—but the wind swings northerly and goes cross-on, then SSW cross-shore. It’s lumpy, questionable. Not your day unless you’re desperate.
Tuesday (8th) sees a big drop to 3ft WSW at 12 seconds, but it’s glassy in the morning with a WNW breeze at 3 mph. Clean little waves, but weak energy—only 585. Fun for a grovel, not a standout. Afternoon fades to 2ft.
Wednesday (9th) stays small, around 3–4ft, cross-off but clean. Honestly, it’s marginal. Then Thursday (10th) gets interesting again—swell jumps to 10ft WSW at 15 seconds, combined energy up at 3953, and it’s clean with a SE cross-off at 19 mph. That’s big, powerful surf, but only for experts. The wind’s not offshore, but it’s not ruining it either. Friday (11th) holds 7ft but the wind cranks to 28–31 mph offshore—so strong it’ll rip your paddle right back. Clean but nearly impossible to get out.
Saturday (12th) is the real standout. Morning has 7ft SW at 14 seconds, moderate SE offshore, clean as a whistle—energy at 2410. Afternoon jumps to 10ft SW at 16 seconds, energy 3832, cross-off breeze. Both sessions are excellent for experienced surfers. If you only get one day in the first week, make it Saturday.
Sunday (13th) fades a touch—7ft SW but cross-shore winds mess it up. Monday (14th) is poor, onshore and messy. Tuesday (15th) brings a big 10ft SW but with strong cross-on winds—lumpy, choppy, not worth the paddle. Wednesday (16th) is big (10ft) and clean-ish with cross-off winds, but there’s rain around and the energy is huge—still experts only.
Now the second week gets spottier. Thursday (17th) drops to 8ft with light cross-on wind—marginal. Friday (18th) drops further to 5ft, clean but weak. Saturday (19th) bottoms out at 3ft—small, clean, not exciting.
Then—hold on. Sunday the 20th looks iffy with cross-on wind, but Monday the 21st is another potential gem. The forecast shows 8ft SW at 13 seconds in the morning with glassy conditions, NE breeze at 3 mph, energy at 1791. Afternoon edges up to 8ft at 13 seconds, still glassy, WNW light air. That’s clean, solid, rideable—excellent for experienced surfers. That’s your long-range hope, and it carries a bit more uncertainty, but it’s got the look.
So overall: first week, bank on Saturday the 12th. Second week, keep an eye on Monday the 21st. In between, there are gaps of a few days where you’ll be better off watching from the rocks. The inconsistent nature of Boneyards means it won’t be firing every session, but when it lines up with that SW groundswell and light wind, it’s as good as it gets.
Rusty out.

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.
