The Lowdown
Alright, Rusty here, looking at the Boneyards forecast for the next couple of weeks. Straight off the bat, we've got a bit of a wait on our hands. The surf is marginal on Monday the 31st of August, with a 7ft WSW swell but a cross-off breeze that's not doing us any favours. Not worth paddling out for.
Tuesday the 1st of September is where it really starts to fire. We've got a solid 10ft SW groundswell rolling in with a nice 13-second period, and the wind is glassy in the morning. That's clean, powerful surf. The water is sitting at 58°, which is a bit colder than normal for this time of year, so you'll be wanting a good wetsuit. The combined energy is strong (3112), and this is the standout window for experienced surfers. The afternoon bumps up to 12ft, but the wind goes cross-on, so it'll get a bit lumpy.
Wednesday the 2nd keeps the fun going. Another 10ft SW swell, 13-second period, clean conditions with a light cross-off breeze. That's a solid day for anyone who can handle it. The wave energy is still very strong (3471).
Then things go a bit wild. Thursday the 3rd sees a 16ft S swell with a shorter 10-second period, but the wind is howling at 34 mph. The combined energy hits 5245, but it's a mess. That's more kite-surfing territory than paddle surfing.
Friday the 4th through to the end of the first week is a write-off. The swell drops right off to under 3ft, and the wind is a strong offshore gale. It's almost impossible to paddle into. The energy plummets to triple digits.
We're looking at a few days of tiny, weak surf after that. A little bump around the 5ft mark on the 6th, but again, strong offshore winds make it a battle. The 7th and 8th are small and not worth talking about.
The second week picks up a bit. Saturday the 12th of September brings back a 7ft to 8ft WSW swell with a 13-second period, clean cross-off winds, and strong energy (1950). That's a promising long-range call, but it's still a way off. Sunday the 13th is similar, 7ft, clean, but the wind is a bit stronger. A solid option for the second week.
Monday the 14th has a glassy afternoon with a 4ft WSW swell, small but clean. Tuesday the 15th looks like a strong, messy write-off again.
So, the standout is Tuesday the 1st of September, with that glassy morning and 10ft groundswell. Wednesday the 2nd is a close second. The second week’s best bet looks like Saturday the 12th, with a clean 7ft+ set. But it's a long way out, so keep an eye on it.
Rusty.

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.
