The Lowdown
Alright, let's break down the next 16 days.
The action starts on Friday the 28th of August at Boneyards. The real standout, though, you want to circle for the morning of the 12th of September.
Friday 28 August afternoon: Boneyards comes in with a clean 4-foot swell from the WSW, 14-second period, combined swell energy at 783. Winds are a gentle cross-off from the SSE. The water temp is 57.9°, which is about 2.3° colder than average for this time of year. That’s a bit noticeable, so don't skimp on the rubber.
Saturday 29 August morning: Swell bumps up to 5.6 feet from the WSW, period stretches to 15 seconds, energy jumps to 1145. Still clean off the ENE cross-off. This is excellent for experienced surfers. Too much for a learner.
Saturday 29 August afternoon: Swell holds around 6.9 feet, but period drops to 10 seconds, and the wind picks up from the south at 15 mph. Conditions get a bit iffy. Not the best pick.
Sunday 30 August: Solid 8.2 feet of SW swell, period at 12 seconds. Wind is cranking from the SSE at 18 mph. Clean in the sense of cross-off, but it’s a stiff breeze. This is expert territory only.
Monday 31 August: Drops to 6.6 feet in the morning from the WSW, 11-second period, light SSE wind. Energy is 1045. This is excellent for experienced surfers again. Afternoon drops to 6.2 feet but stays clean and good.
Tuesday 1 September: Big day. 9.8 feet of SW swell, 13-second period, energy at 2561 in the morning, 2830 in the afternoon. Winds go cross-shore from the SW and SSW. Choppy and powerful. Experts only.
Wednesday 2 September: The biggest day. 13.1 feet of SW swell in the morning with a 15-second period and energy at 6902. Afternoon drops to 11.5 feet. Winds are strong from the SSE. Clean, but this is for the hardcore crew only. If you’re not experienced, watch from the cliffs.
Thursday 3 September: Swell backs off to 6.6 feet in the morning from the WSW, 12-second period. Wind goes offshore from the SE at 28 mph. Clean, but hard to paddle into. By the afternoon, the wind hits 40 mph from the SE. That’s gale force. Not worth the fight.
Friday 4 September: Swell is tiny—2.3 feet to 2.6 feet. Winds are still gale force in the morning, strong through the afternoon. The ocean is blown out.
Saturday 5 September: Swell holds around 3.0 feet. Moderate offshore wind in the morning at 12 mph from the SE. Clean but small. Energy is low (272). You could get a few small ones, but don't plan a trip around it.
Sunday 6 September: A new long-period swell arrives. 4.3 feet to 4.6 feet from the SW, period jumps to 18 seconds in the morning. That’s a very long groundswell. Energy is 1160–1251. Winds are light cross-on from the W and NW, so there’s a bit of ripple. The long period can make it run straight at the reef. Rideable for the patient.
Monday 7 September: Swell drops to 3.6 feet to 3.9 feet, from the WSW with a 13-second period. Wind is from the NNW at 12-15 mph, cross-on and choppy. Poor conditions.
Tuesday 8 September: A gem. The morning is glassy. Swell is 3.9 feet from the

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.
