The Lowdown
Alright folks, Rusty here. We’ve got a solid run of groundswell lining up for Boneyards over the next couple of weeks, but this is strictly for the crew who know what they’re doing. This is a heavy reef break and it’s only for advanced surfers.
The water temperature is 53°F, which is far colder than usual for this time of year, so don’t even think about going out without a proper hooded 5/4, booties, and gloves.
The surf kicks off this Sunday, August 16th, with clean 5ft SW groundswell and a 13-second period. The combined wave energy is moderate (987) and the wind is cross-offshore from the west, so although it’s not huge, the quality is there. This is more of a warm-up session. Monday morning, August 17th, brings a jump in size to 7ft from the SW, with a 14-second period. The energy bumps up to strong (2017) and the light cross-off wind keeps it clean. This is legit, but at 7ft it’s getting into expert territory.
Tuesday, August 18th, holds similar goods: morning waves at 7ft (1508 energy), and the afternoon builds to 8ft with a solid 13-second period and energy climbing to 2134. Still clean with light cross-off winds.
Now, the absolute standout of this whole window is Wednesday, August 19th, morning. We’ve got 8ft SW swell, a 13-second period, a massive energy reading of 2174, and the wind is glassy. That means no bumps on the face at all – it will be as perfect as Boneyards gets. This is the session to point your car at. The afternoon does get a moderate breeze, so the morning window is key.
Thursday, August 20th, morning holds 10ft SW with strong energy (2569) and light cross-off wind. The afternoon though, gets a cross-on wind and hits 12ft, which makes it more of a washing machine and too gnarly for most. Friday, August 21st, morning is another glass-off gem with 8ft SW and calm winds – autumn-like conditions and definitely worth a paddle.
Saturday, August 22nd, gets blown out by a near gale in the afternoon (31 mph), so the weekend takes a hit. Sunday, August 23rd, afternoon sees a massive jump to 13ft SSW with a 16-second period and energy skyrocketing to 8385. This is huge, heavy, and borderline scary. Only for the most experienced locals.
Monday, August 24th, morning is the real monster: 13ft SSW, 16-second period, glassy, with energy at 7830. This is an “exceptional for experts” call. That said, with that period, the sets will be widely spaced and it will be breaking straight on the reef – not a beachbreak, so it should hold shape, but it’s a serious paddle out. The following weeks have more solid SW swell in the 10-12ft range, with the next glassy window looking good on Monday, August 31st, morning with 12ft SW and calm winds (5115 energy). That’s a solid late-summer option, but still a long way out.
Crowds here are “sometimes” an issue, and with this quality of swell, expect a few locals out, but the difficulty keeps the crowds manageable. In the second week, conditions are more marginal with moderate to fresh winds, but the size stays up. For the second week, the 30th of August morning looks most promising with 12ft SW and a long 15-second period, but the wind is fresh.
For anything above 8ft, don’t even think about bringing a beginner. This is a reef, and it will punish mistakes.
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.
