The Lowdown

Alright, Rusty here. Let’s talk about what’s coming up for Boneyards. This is a reef setup, so it’s got that potential for a proper shape, but it’s inconsistent and can be a bit fickle. The water temp is about average for this time of year, nothing crazy to report.

Right now, it’s a bit of a slow start. The first swell we see is on Monday, September 7th, with a solid 7ft southwest swell at 14 seconds, but the wind is from the NNW, making it cross-on and a bit messy. The energy is strong, clocking in at 1549, but it’s just not clean enough to get excited about. That afternoon, it drops a touch to 7ft, but the wind swings south-southwest, keeping it cross-shore and crumbly. Honestly, not worth paddling out for.

Tuesday, September 8th, is where you want to be. The morning is all glassy, with a 3ft west-southwest swell at 12 seconds. The energy is moderate at 585, but with that glassy surface, the conditions are spot on. It’s small, but it’ll be clean and fun for a reef wave. The afternoon stays clean, but the swell drops to 2ft, so it’s a bit of a knee-slapper. That morning session is the standout of the first week.

Wednesday, September 9th, the wind picks up from the south-southeast, and even though the swell is around 3ft to 3ft, the breeze is too strong for it to be quality. It’s clean, but the energy is low, and the vibe is just off.

Now, Thursday, September 10th, things get serious. We’re looking at a 10ft southwest swell at 16 seconds in the morning – that’s a long-period groundswell with some serious energy (4361). But, the wind is cross-off from the south-southeast at 25 km/h, making it clean but a bit tricky. This is a big swell for Boneyards, and because it’s a reef, that long period should wrap in nicely. However, at 10ft, this is expert territory. If you’re not comfortable on a big, hollow reef, stay on the beach. The afternoon holds similar size but drops to a 14-second period, still hefty.

By Friday, September 11th, we’ve got strong offshore winds from the southeast, 45 km/h in the morning. That’s strong offshore, which means the waves will be clean and steep, but paddling out will be a battle. The swell is 7ft at 13 seconds. It’s a real struggle session. The afternoon is a near-gale, so forget it.

The real standout in the whole 16-day window is Saturday, September 12th. The morning delivers a 7ft southwest swell at 14 seconds with a moderate offshore wind from the east-southeast at 20 km/h. The energy is strong at 1422, and conditions are clean. The swell direction (SW) matches the optimum for Boneyards, so this is going to be a proper, punchy reef wave. It’s a standout for experienced surfers. The afternoon jumps to 8ft with a 16-second period, but the wind goes cross-off, so it’s still good, but the morning is the magic window.

Sunday, September 13th, and Monday, September 14th, are a write-off. The wind swings to the north-northwest, cross-on, and the swell is messy. We’re talking lumpy, choppy, and poor. Don’t bother.

Tuesday, September 15th, is pure chaos. A 13ft to 15ft southwest swell, but with a strong cross-on wind. It’s huge, but it’s blown out. That’s more of a kite-surfing day than a paddle session.

The rest of the second week is a bit of a mixed bag. Wednesday, September 16th, has a clean 8ft swell with strong cross-off winds, it’s okay but not a standout. Thursday, September 17th, has strong offshore winds again, making it hard work. Friday, September 18th, is a nice surprise – a 3ft south swell with a light offshore from the east. That’s clean and small, good for a longboard or a fun fish. Saturday, September 19th, starts small but builds to 5ft by the afternoon. Sunday, September 20th, has a clean 7ft west-southwest swell, but it’s a bit crowded likely.

So, to wrap it up: the best on offer is Tuesday morning, September 8th, for the glassy, small-wave fun, and Saturday morning, September 12th, for the bigger, clean, powerful reef waves. The long-range stuff around the 20th is promising, but less certain. Keep an eye on that Saturday morning window.

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.
