The Lowdown
Alright, this is Rusty, and I’ve got a good look at what’s coming up for the next few weeks.
The surf is already starting to build in the water, and the first real chance to get wet is on Tuesday afternoon. We’re looking at a solid foundation of groundswell sticking around for a while, but the wind is going to be the main character shaping the sessions.
The action starts on Tuesday, August 11th, with a small but clean 2ft swell out of the SW. The water is sitting at 57°, which is a bit colder than what we usually feel this time of year. The real standout, though, is Wednesday, August 12th. The swell jumps up to a solid 6ft in the morning, also from the SW, with a very long period of 18 seconds. That’s proper groundswell. The wind is light and cross-offshore, making for a clean surface. By the afternoon, the wind drops to glassy conditions, and the swell is 7ft at 17 seconds. This is the best of the bunch for the first week. The wave energy is strong at 2454, and that glassy afternoon session is going to be a ripper for experienced surfers.
Thursday morning, August 13th, still has strong 8ft SW swell and a gentle cross-shore wind, but it’s a bit fat and bumpy. The energy is very high at 3538, but it’s not the cleanest. The second half of the week sees the swell drop and the wind turn more cross-onshore, making Friday and Saturday morning a bit of a write-off for the average punter.
The second week is a mixed bag, but there’s a very promising window. Saturday, August 22nd, kicks off with a glassy morning and 5ft of SW swell. That’s a sneaky good session. But the real long-range standout is Sunday, August 23rd. The morning is a bit average, but the afternoon shows a 6ft SSW swell with a 16-second period and a moderate offshore wind. The energy is very high at 2883, and that’s going to be a clean, powerful afternoon. Monday, August 24th, is also a beauty: 8ft SW swell, with a light offshore wind in the morning. Then Tuesday, August 25th, is a dream forecast with zero wind, glassy conditions, and a solid 8ft SW swell at 14 seconds. That is the standout of the entire run. The wave energy is strong at 1951, and it’s begging for a longboard or a step-up.
Just a heads up, Boneyards is a reef break, so it’s best for intermediate to experienced surfers, especially when the swell gets over 8ft. It’s inconsistent, so patience is a virtue. The crowds can show up sometimes, but when it’s this good, that’s hardly a surprise.
This is Rusty, signing off.

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.
