The Lowdown

Rusty here, let's talk about what's brewing at Boneyards.

Alright, Boneyards is a reef break, and it's inconsistent, so when it gets a run of waves, you want to be on it. The water temp is sitting at 57°F, which is a bit colder than normal for this time of year, so you'll want a good suit.

The outlook starts with a bit of a struggle. We've got waves on the 16th, but the wind is howling. Wednesday morning sees an 8ft WSW swell but with a strong 22 mph cross-off wind, and the wave energy is pumping at 3779 (moderate energy), but it's gonna be a wrestling match. The afternoon is no better, with the wind picking up to 28 mph. Thursday and Friday are more of the same – the swell is there, 7ft and 6ft, but those strong to near gale force offshores are making it nearly impossible to paddle into. Saturday is a write-off with near gale-force winds.

There's a real lull in quality until the 21st. Monday the 21st morning finally gives us a break. The swell drops to a manageable 5ft from the SW, the wind eases to a moderate 12 mph offshore, and the combined energy is 578 (weak energy). It’s clean and rideable.

But the real standout is Tuesday the 22nd. That morning, we've got a 3ft SW groundswell with a 13-second period and the wind is glassy – 3 mph from the south. That's as good as it gets. The energy is low at 501 (weak energy), but for a clean, small-wave session, it’s perfect. The afternoon is also clean with a gentle breeze.

Then things get heavy. From the 23rd, the swell cranks up. Wednesday the 23rd afternoon sees an 12ft SW swell with strong offshore winds, but that's getting into expert-only territory. Thursday the 24th morning is massive: an 12ft SW swell with a very long 15-second period, energy at 5785 (strong energy). But the wind is a cross-shore, making it lumpy. This is big, powerful, and messy – honestly, at a reef break with that much energy and a cross-wind, this setup looks more interesting for kite surfing than paddle surfing.

For the rest of the run, Saturday the 27th morning is your best call for a proper session. The swell is 8ft from the SW, the wind is a light 6 mph offshore, and the energy is 2565 (moderate energy). It’s clean, powerful, and built for experienced surfers. That's the one to circle.

The first week is mostly blown out or gale-force, with only a few windows of clean, smaller surf. The second week brings the size, but the wind gets tricky.

All in all, Boneyards is inconsistent, so when it’s good, it’s special. The 22nd is a glassy gem for a quiet session, and the 27th morning is the heavy-hitter for those who can handle 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.
