The Lowdown
G’day, Rusty here. Looks like we’ve got a real mixed bag coming our way over the next couple of weeks, with one solid standout that’s worth circling on the calendar.
We’re kicking things off with a proper heavy-hitter. Monday the 31st of August is the pick of the entire forecast, and it’s a cracker. Boneyards is a reef break that demands respect – this is advanced territory only, and it’s consistent. Water temps are sitting at 61°F, which is much colder than usual for this time of year, so you’ll want a good hood and gloves. Monday morning serves up glassy conditions with clear skies and zero wind. Swell is a clean 6ft from the SW with a solid 12-second period, and the combined energy is pumping at a strong 1091. That’s proper groundswell energy. The offshore wind is from the WNW, and it’s dead calm – so expect smooth, groomed faces. This is excellent surf for experienced surfers, and it will be well worth the early alarm.
Monday afternoon sees the wind shift to a light cross-on from the SSE at 6 mph, and the swell drops off significantly to just 2ft from the E. The energy falls right away to 123, so don’t expect much. That morning session is the one.
Tuesday the 1st of September brings a bigger pulse. Morning has a 8ft SW swell at 12 seconds, with the combined energy sitting at a meaty 1463. But the wind is a light cross-on from the SSE at 3 mph, so the surface won’t be perfect. The afternoon pushes up to 8ft from the SW with a huge energy reading of 2159, but it’s onshore from the ESE at 6 mph – still rideable for the diehards, but not clean.
Wednesday the 2nd sees the swell jump to 10ft from the SW with a 13-second period. Morning energy is a massive 3391, and the wind is only a light cross-shore from the SSW at 3 mph. That’s big, powerful surf – definitely expert territory at over 8ft – and the longer period will hold up well on a reef. But it’s not glassy, and the afternoon gets messy with a stronger onshore.
From Thursday the 3rd through to Tuesday the 8th of September, it’s a write-off for quality surfing. The swell stays big – up to 10ft and even 13ft on Friday the 4th – but the wind is relentless onshore or cross-onshore, often strong, with readings like 28 mph and 25 mph. The energy numbers are off the charts (up to 11289 on Sunday afternoon), but it’s just blown-out and messy. If you’re a kite surfer, that Sunday session with a 15ft S swell and fresh onshore wind might be your jam. For paddle surfing, it’s a no-go.
After that rough stretch, we get another window worth a look. Wednesday the 9th of September morning sees the swell ease to 6ft from the ESE with a 9-second period, energy at 921. The wind swings to a light cross-off from the NNW at 3 mph, and conditions are described as clean. That’s a promising morning session with clean, groomed waves. The afternoon keeps it clean with a cross-off from the WSW at 9 mph and a 7ft ESE swell at 12 seconds – energy sits at 1297, so a bit more power, and still workable.
Friday the 11th of September morning is another chance. Swell drops to 4ft from the ESE at 11 seconds with 501 energy, but the wind is a light cross-off from the N at 6 mph, making for clean conditions. Smaller, but clean and fun for the experienced crew.
After that, the swell fades and the wind patterns get more mixed, with a few marginal windows but nothing that stands out as a must-surf. The run from the 12th onward is mostly small, onshore, or choppy.
So to wrap it up: the absolute standout is Monday morning, August 31st at Boneyards – glassy, clean, solid 6ft SW groundswell, and very cold water. That’s the one to aim for. Wednesday the 9th and Friday the 11th offer smaller but clean sessions as a backup. The middle of the first week is big and blown out, so save your energy for that opening morning.
Stay warm and get after 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.
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.
