The Lowdown
Alright, let’s talk about what’s brewing for the next 16 days. Only one spot is really in the game, and that’s Tubes. It’s a reef and point break, consistent, so we’ve got something to hang our hats on.
The water temperature at Tubes is 58°, which is a massive 8° colder than normal for this time of year. That’s a serious anomaly – you’ll be needing a thick suit, no doubt.
The forecast starts on Monday, August 10th. We’ve got a solid 8ft swell from the SW, with a 12-second period, and the combined energy is pumping at 2088 (moderate wave energy). The wind is a cross-off from the S at 12 mph, so the morning session is looking clean. The afternoon gets a bit bigger at 10ft, but the wind swings SE and goes cross, making it choppier. It’s marginal, but Monday morning is the pick of the early days.
Tuesday the 11th is a washout – strong cross-on wind and lumpy conditions. Wednesday the 12th is even worse with a fresh breeze making it messy. Thursday the 13th has a clean morning with light offshore wind from the ENE at 6 mph, and a 5ft SW swell with a 16-second period – that’s a long period groundswell, which will wrap nicely around the point. Combined energy is 2019. It’s still a bit marginal, but the morning has potential. Friday the 14th is a no-go until the afternoon, when a light onshore breeze from the NNE at 3 mph gives us a clean 5ft SW swell, but it’s still marginal.
Now, the real standout comes on Sunday, August 16th. The morning has a light cross-off wind from the W at 6 mph, and the swell is 4ft from the WSW with a 13-second period. The afternoon is even better – offshore wind from the SW at 9 mph, glassy clean conditions. This is the best on offer in the first week. The water is still cold, but the waves will be clean and fun.
Monday, August 17th morning is another absolute gem. Glassy conditions, a light SE breeze at 3 mph, with a 5ft SW swell at 13 seconds. The combined energy jumps to 1232, meaning the swell has some punch. That’s a top-shelf session, but it’s short-lived – the afternoon turns into a cross-on mess.
The second week gets a bit more mixed. Tuesday the 18th has a clean morning with a cross-off from the WSW at 22 mph, which is fresh, but the swell is 6ft from the SW. The afternoon goes offshore clean. Wednesday the 19th morning is another clean one with gentle offshore wind from the SSW at 9 mph, 6ft SW swell. That’s a good one.
But then we hit a few days of poor conditions from Thursday the 20th through to Friday the 21st of August, with strong cross-on winds and messy surf. The swell on the 21st is big though – 10ft from the ESE at 11 seconds – but with a fresh cross wind, it’s more of a kite surfing setup than a paddle session.
Saturday, August 22nd morning is a surprise. Clean conditions, light offshore wind from the SSW at 6 mph, and a small 2ft SSW swell with a very long 18-second period. That’s a groundswell that will wrap well on the point, but the size is small. For a quiet, clean wave, it’s a nice option.
The final standout is Monday, August 24th afternoon. The wind goes offshore from the SW at 6 mph, with a solid 8ft SSW swell at 12 seconds. Combined energy is 1740. That’s going to be clean and powerful. If you’re an intermediate to expert, that’s the session to aim for in the second week.
Overall, the best windows are Sunday the 16th and Monday the 17th morning, then Monday the 24th afternoon. The rest is a mix of marginal and poor conditions, with some clean mornings scattered in between. Crowds are possible at Tubes, so keep an eye out.

Information about the Tubes Surf forecast
The above surf forecast table for Tubes provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Tubes can be found by selecting the local surf guide option on the grey menu. Our Tubes 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 (Tubes) 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 Tubes 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.
Tubes 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.
