The Lowdown

Alright, Rusty here. Let’s have a look at what we’ve got coming down the pipe.

The next couple of weeks are a mixed bag at Boneyards. We’ve got some solid swell windows, but the wind is going to be a real moody bugger for a lot of it. The water temp is a bit cooler than normal, sitting at 58°, nothing too freaky, just a bit of a chill.

We kick off Sunday, August 30, with a 8ft swell coming from the SW. The wind is a cross-off from the SSE, so it’s clean but with a bit of energy behind it. The combined energy is strong (2172). It’s a bit on the bigger side, so keep your wits about you. Monday, the 31st, sees the swell drop a touch to 7ft from the WSW, wind easing off to a gentle cross-off. Still clean, still holding some moderate-strong energy (1045). A solid Monday morning session.

Then things get interesting. Tuesday, September 1, the swell jumps up. We’re looking at 10ft to 12ft from the SW, with a long 13-second period. The energy is very strong (2824 and 3846). The wind goes cross-shore, so there’ll be some texture. This is big, powerful water. At 10ft you’re talking expert territory only, and at 12ft it’s getting properly heavy. Not a day for the faint-hearted.

Wednesday, September 2, still has 10ft from the SW, but the wind backs to a cross-off from the SSE, so conditions clean up nicely. The energy is still very strong. This is a better day for it if you’ve got the skill.

The standout window is Thursday, September 3, morning. You get 6ft from the WSW with a 12-second period. The wind is a light offshore from the ESE, making for excellent, clean conditions at this reef. The energy is moderate-strong (1541). This is your call to go. The break is inconsistent, so you’ll be waiting for the sets, but when they come, they’ll be lined up and clean. Perfect for the experienced surfer.

The rest of that week into the weekend gets blown out. Strong winds from the SE hammer things from the 4th to the 5th. The swell drops off (4ft to 5ft), and even though the energy is weak to moderate, the wind is a gale. It’s not worth paddling out.

We get a reprieve on Sunday, September 7. The morning is glassy, with a slight air from the SSW. The swell is a smaller 5ft from the SW with a long 14-second period. The energy is moderate (1004). This will be clean and cruisy, a good day for it. The afternoon even goes glassy at 5ft, proper smooth.

Another strong option is Tuesday, September 8, morning. Offshore wind from the ESE, a clean 6ft from the W with a very long 14-second period. The energy is moderate-strong (1229). That long period will wrap into this reef nicely. Keep an eye on this date.

The second week starts to look promising but less certain. Friday, September 11 afternoon, a big pulse of 10ft from the SW with a 15-second period hits, but the wind is a strong cross-off. The energy is very strong (4218). Saturday, September 12, morning is cleaner, with a fresh offshore from the ESE, still big at 10ft from the WSW with a 13-second period. Energy is very strong. That’s expert-only territory.

Sunday, September 13, goes onshore from the NW, ruining the 5ft swell. Monday, September 14, looks to have a beast of a swell: 10ft to 12ft from the SW with a 15-second period. The wind is either onshore or cross-off, but the energy is enormous (4737 to 4820). If the wind plays ball, that could be a day for the big-wave crew, but it’s a long way off.

All in all, the best bet is Thursday, September 3 morning for clean, lined-up waves, and Tuesday, September 8 morning for a glassy, long-period session. The rest you have to pick your windows carefully.

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.
