The Lowdown
Hey gang, Rusty here. Let’s talk about Tubes over the next couple weeks – it’s a bit of a slow start, but the payoff is huge if you wait for the right windows.
Right now, Monday the 7th is a total wash. You got an 8ft swell from the SSW, but the wind is blowing onshore and it’s all chopped out. The water is a chilly 60°, which is 6° colder than it should be for this time of year – bring the 5/4. Just give it a miss.
Tuesday morning the 8th is a breath of fresh air. It’s glassy calm with a clean 4ft swell out of the SW. Wave energy is moderate (697), but with zero wind, it’ll look like a lake with peaks. Great little session.
Mark Thursday the 10th down. The afternoon is showing a solid 5ft SW groundswell with a super long 16-second period, and the wind is offshore from the SW at 12 mph. The energy jumps to a strong 1522. That’s a clean, long-running point and reef wave.
But the absolute standout is Saturday the 16th. The morning brings a monster 15ft SW swell with a 17-second period – that’s a 11007 energy reading, which is insane. The wind is howling offshore at 16 mph. This is for experts only – over 8ft means it’s too big for most, and the reef will be firing. It’s gonna be a proper big-wave day, but the long period means the sets will be clean and powerful. Totally unmissable for the brave.
The following week, Sunday the 20th morning is another excellent call: glassy conditions on a 7ft SW swell with strong energy (2166). That’s a solid day for experienced surfers.
There’s some choppy, cross-onshore days in between, but the good windows are perfect. Tubes loves a SW swell with that offshore wind, and when it all lines up, it’s one of the best setups around.
The 16th is your big date. Don’t sleep on it.
Catch you in the water,
Rusty

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.
