The Lowdown
Howdy, Rusty here. Bit of a lull before the big stuff hits. First decent surf shows up Friday afternoon, August 28, at Boneyards – a reef break that doesn’t fire often, so keep that in mind. Water temp is 59°F, a touch cooler than average for now.
Friday, August 28 morning is junk – cross-on breeze, 4ft south swell, not worth it. Afternoon cleans up: light cross-off wind, 4ft WSW swell with a long 14-second period, combined energy sitting at 783 (moderate). The reef will hold it, but the spot’s inconsistent so patience is key.
Saturday, August 29 morning is the pick. 6ft of WSW swell at 15 seconds, offshore east wind, light breeze – combined energy hits 1145 (strong-moderate). This is for experienced surfers only – over 5ft, groundswell, the reef will line it up. Crowds can show sometimes, but you’ll get waves if you’re keen. Afternoon sours: 7ft, fresh 19 mph southerly cross-off, light rain – marginal at best.
Sunday, August 30 – 8ft from the SW, but a strong 19 mph cross-off all day makes it choppy. Energy is still high (2272 and 1765), but it’s rough. Not your friend.
Monday, August 31 drops to 7ft and 6ft, light to gentle cross-shore winds. Period drops to 11 seconds. Rideable but average.
Tuesday, September 1 – 8ft again from the SW, long-period (13-14 seconds), light onshore, unknown quality. High energy (2180-2484) but a gamble.
Wednesday, September 2 is huge: 16ft of SW swell at 16 seconds, combined energy 11317 – very strong. But a 25 mph cross-off from the SE keeps it clean yet massive – experts only. Afternoon holds 13ft. This is survival, not fun.
Thursday, September 3 and Friday, September 4 are trashed by near gale to gale force offshore winds (34-40 mph from the SE). Swell still 8ft and 6ft, but you can’t paddle in – kite-surfing territory.
From Saturday, September 5 to Tuesday, September 8, swell drops to 1-3ft. Combined energy under 100-500. A clean window Tuesday morning (light cross-off, 3ft) but it’s weak.
Wednesday, September 9 morning gives you 3ft at 12 seconds with gentle offshore – clean, small, longboard stuff.
Thursday, September 10 and Friday, September 11 are mostly poor, though Friday afternoon has 3ft from the WSW, clean cross-off – marginal but possible.
Saturday, September 12 – 7-7ft from the SW at 14 seconds, but a fresh 19 mph cross-on makes it lumpy. High energy (1846-1920) but messy.
Best of the lot: Saturday, August 29 morning at Boneyards – clean offshore, 6ft, long-period groundswell, reef handles it. Second: Friday, August 28 afternoon for a cleaner but smaller session. The big mid-week stuff is for experts only and wind’s a factor.

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.
