The Lowdown

Alright, let me get into this. It’s Rusty here, and I’ve been staring at Boneyards for a while now. It’s a reef break, and for the next 16 days, you’re gonna have to be patient with it.

The run starts on Monday the 7th of September with a pretty mixed bag. That Monday morning has a 7ft SW swell, but the wind is a light cross-on from the NNW, so it’s not gonna be that clean. The water temp is sitting at 57°, which is a bit colder than normal for this time of year—feels like we’ve skipped a couple of warm days. The wave energy is strong, but the condition is marginal. There are better windows coming, but Monday is a skunk day.

Tuesday the 8th is where it gets interesting. The wind goes totally glassy in the morning (SSE, 0 mph), and we’ve got a 3ft WSW groundswell with a period of 12 seconds. That’s a clean, long-period swell that will wrap into the reef nicely. The energy is moderate, but when it’s glassy and the swell has that pulse, Boneyards can handle it for an intermediate surfer. The afternoon picks up a clean 2ft swell with a slight cross-off breeze—still decent, but the morning is the better session.

Wednesday the 9th sees the swell staying small, around 3ft from the WSW, with a 13-second period. It’s clean enough with a cross-off wind, but the wave energy is on the lighter side. It’s okay, but not a stand out.

Now, the big alert is Thursday the 10th of September. The morning has a 10ft SW swell, period of 16 seconds—that’s groundswell, and it’s pushing serious power. The combined energy is high. But the wind is a cross-off from the SE at 12 mph, so it’s clean. This is big, but over 8ft, so this isn’t for beginners. It’s for the experts. The afternoon stays over 8ft with the swell from SW, period 14 seconds, and a little stronger wind (19 mph) but still cross-off. That one’s a big, clean wall, but it’s a reef, so take care.

From Friday the 11th through the 14th, it blows up. Near gale winds on the 11th (31 mph) and then consistent strong winds keep the surface rough. The swell stays solid—6ft to 8ft—but the conditions are poor to blown out. There’s a brief window on Saturday the 12th morning with an offshore wind from the SE, and a 5ft SW swell (14 seconds), making it clean, but the wind is fresh and challenging. It’s marginal.

The 15th of September gets very big again—15ft from the WSW in the afternoon, but it’s accompanied by near gale cross-onshore winds. That one is only for the suicidal.

A late window appears on the 16th of September (Wednesday): an 8ft SSW swell, period 13 seconds, with a cross-off wind from the S at 19-22 mph. The energy is moderate to strong. The conditions are clean enough, but that’s still over 8ft, so expert territory only.

After that, from the 17th onwards, the wind gets nasty again, strong offshore (near gale) that makes it nearly impossible to paddle into anything, even if the swell drops to 5ft or 3ft. The last few days (19th to 22nd) are small and generally poor.

So, what’s the best? Tuesday the 8th of September morning: glassy conditions and a clean 3ft, 12-second groundswell. That’s the standout for intermediates. For the big stuff, Thursday the 10th morning is the best for experts—10ft, 16-second groundswell with clean cross-off wind. Plan your sessions around windows, because the gaps (like the 11th to the 14th) are frustrating.

This is a reef break that can deliver, but it’s inconsistent and it rewards patience. It’s not always breaking, but when it does with the right wind, it’s worth 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.
