The Lowdown

Alright, surfers. Rusty here. Let’s take a look at what’s cooking for Boneyards. To be straight with you, this is a tricky stretch for that spot. It’s an exposed reef break that needs a solid W swell, and while the size shows up, the wind plays dirty more often than not.

We kick things off on Tuesday the 8th, but it’s a real slow start. Tuesday morning offers a modest 3ft WSW swell, but with a light cross-onshore breeze, the surface is a bit of a mess. The swell energy is moderate (585). The water is a chilly 56°, which is much colder than normal for this time of year—a pretty unusual drop of over three-and-a-half degrees. It’s not worth paddling out. Tuesday afternoon drops to 2ft. A couple of days of small, clean-ish surf follow on Wednesday the 9th (3ft to 4ft) with light cross-off winds, but it’s small and the crowd factor is a real gamble here.

Things get interesting on Thursday the 10th. The swell jumps to 8ft from the SW with a solid 14 second period on Thursday morning, and strong moderate wave energy (2590). But it’s cloudy with a fresh cross-off breeze; still clean, but that’s heavy for this reef. That’s well over 5ft, so not for beginners. Friday the 11th is a no-go due to screaming fresh to strong onshore winds. Saturday the 12th sees a massive 8ft SW swell with a very long 16 second period on the afternoon, building monster energy (4377), but the wind is howling, making it unsurfable. This is kite-surfing territory.

The first real standout—and it’s a beauty—is Sunday the 13th. Finally, the stars align. The swell settles to a clean 7ft to 6ft from the SW with good period (13-14 seconds), and the wind goes light. Sunday morning is nearly glassy with just a slight air, and the afternoon has a light offshore breeze. The scores for experienced surfers are excellent. The crowd situation here is "sometimes" busy, so with conditions this good, expect plenty of company. This is your window.

Then the wind goes nuts again. Monday the 14th is blown out with a messy cross-shore wind and a short-period windswell. Tuesday the 15th is a total nightmare—strong cross-onshore winds with a massive, messy 22-second groundswell creating complete chaos.

We get another huge pulse on Wednesday the 16th: a 13ft WSW swell (very strong energy - 6637) with clean cross-off winds in the morning. That’s big, solid, expert-only territory, and the wind is moderate, so it might be workable for the brave but it’s a real battle. Thursday the 17th is ruined by a near-gale offshore wind.

The second standout rolls in on Friday the 18th. A solid 8ft SW swell with 14 seconds of period and clean, moderate offshore winds. The energy is strong (2686). This is excellent for experienced surfers. It’s followed by Saturday the 19th morning, which is the other absolute gem: a 6ft WSW swell with glassy conditions. That’s pure, uncrowded-looking magic for the intermediate. That morning window is as good as it gets.

The end of the run gets messy again. Sunday the 20th brings a massive 15ft SW swell but with choppy, moderate cross-onshore wind. A few more days of smaller but clean surf roll through the 21st and 22nd, with manageable 6ft to 7ft, but nothing special. Finally, on Wednesday the 23rd, it builds to a 15ft SSW monster with a very long 17-second period and massive energy (12293), but the wind is clean, making it a big-wave specialist day only.

So, bottom line: Sunday the 13th and Saturday the 19th morning are your true standouts. The rest is either too small, too windy, or way too big.

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.
