The Lowdown
Alright, grab your wettie. Let’s have a look at what’s doing at Boneyards.
First thing you need to know, the water is sitting at 60° – that’s 6° colder than it should be for this time of year. That’s seriously unusual, so bring the thickest rubber you’ve got.
Now, if you’re keen to paddle out, the early run looks pretty ordinary. The first solid hint of something worth getting out of bed for isn’t until Monday afternoon, September 14. It’s a bit messy in the morning, but by the arvo the wind swings offshore from the WSW at 16 mph and the sea cleans right up. We’re looking at 8 ft swell from the east at 10 seconds. The combined energy is moderate (1571). It’s not the biggest, but the clean conditions make it a genuine chance for a surf.
Tuesday morning, September 15, shapes up as the first real standout. Glassy conditions with a light cross-offshore breeze from the WSW at 6 mph. Swell drops a touch to 6 ft from the east, period 11 seconds – that groundswell feel – and the energy still sits at a solid 1175. It’s clean, lined up, and you’ll have the place to yourself if you get in early enough. This is the pick of the first week.
The other bluebird session to lock in is Wednesday morning, September 16. A proper 10 ft SW groundswell rolling in at 14 seconds – very long-period energy – combined energy of 3491 (strong). Light offshore WSW breeze at 6 mph. This is proper reef-swell. It’s going to be pumping, but that size puts it squarely into advanced-only territory. The long period will make it suck hard and stand up fast over the reef – a serious session for the crew who know what they’re doing.
After that, a run of poor conditions rolls in from Thursday the 17th right through to Sunday the 20th. Moderate to fresh onshore easterlies will chop it up. Not worth the look.
Monday morning, September 21, things start to turn again. A 7 ft easterly swell with a light sea breeze – manageable, but still a bit bumpy.
Another big highlight lands on Thursday afternoon, September 24. A clean, moderate offshore breeze from the WNW at 12 mph cleans up a 5 ft SW groundswell with a 13-second period. Energy is 1487 – moderate but well organised. That offshore flow will groom it perfectly. The swell direction from the southwest matches right up with what Boneyards loves. This is the best call of the whole second week.
Friday, September 25 rolls on with clean conditions too – a moderate cross-offshore breeze and a 8 ft east-southeast swell in the morning, dropping to 8 ft in the arvo, both with decent energy around 1400. Long, clean lines.
After that, the last few days drop off again; the east-northeast breeze on Sunday the 27th brings a tiny 3 ft SW groundswell with a very long 19-second period. That long period will make it wall up and run way too fast for the beach – not much to get excited about.
So the standout windows are Tuesday morning, September 15, and Thursday afternoon, September 24. Both offer solid, clean surf with the right wind for Boneyards. The Wednesday morning on the 16th is for the experienced crew only.
Keep an eye on that water temp, and get out there when it’s good.

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.
Boneyards is 19 km (12 miles) from the city of Kruisfontein. If you plan a holiday in Eastern Cape (South), look for hotels and other accommodation in Kruisfontein. Kruisfontein has rooms for a wide range of budgets as well as car hire and transport links.
