The Lowdown
Alright, let’s take a look at the next couple of weeks. Boneyards is the only spot in the frame, and it’s a reef that needs a good southerly swell. The water is 62° and a bit colder than usual for this time of year, so you’ll want some rubber.
The first few days are a total loss. Friday the 4th and Saturday the 5th have onshore winds and poor surf. Sunday the 6th has some serious size, 12 feet, but the wind is blowing it out, making it lumpy and ugly.
Monday the 7th is still a little rough, but it’s a step in the right direction.
The first real standout is Tuesday morning the 8th. The wind is dead glassy, flat calm, and the swell is 4 feet from the SW. The combined energy is moderate at 1193. It’s clean, lined up, and the conditions are excellent for experienced surfers. This is your window. The period is 13 seconds, so it’s real groundswell.
Wednesday morning the 9th looks clean too, with a light cross-offshore breeze and 4 feet of swell. A little smaller, but still good.
Thursday the 10th is a bit quiet with smaller waves and moderate wind.
Friday the 11th morning brings it back: 7 feet of clean, long-period SW swell (14 seconds) and a light cross-offshore wind. The combined energy is strong at 1640. This is another excellent session for the experienced crew. The afternoon goes bad with rain and onshore wind, so get it early.
The weekend of the 12th and 13th is a mess with strong cross-onshore winds and lumpy, miserable conditions.
Now, look ahead to Tuesday the 15th. The morning is glassy, dead calm, with 8 feet of clean SW swell and a 12-second period. Combined energy is strong at 1896. This is a serious session for advanced surfers.
Wednesday the 16th morning is another clean, glassy, excellent call with 7 feet of long-period SW swell.
The big one, the one that stands out, is Thursday the 17th afternoon. The combined energy is huge at 9701, with 12 feet of SW swell and a 15-second period, with a clean cross-offshore breeze. The wind is a moderate 20 km/h, and the conditions are marginal – but only experts looking for a challenge should even think about it. This is a monster groundswell.
After that, the swell drops and the wind turns ugly again for the final few days. The 18th and 19th are mostly onshore and messy.
So, to sum it up: the best bets are the Tuesday morning the 8th for a clean, glassy session, and the Thursday morning the 11th for a strong, clean, long-period swell. If you’re a charger, the afternoon of the 17th is the one. Get out there.

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.
