The Lowdown
Alright, Rusty here. Let’s take a look at what Magna Tubes has in store for us over the next couple of weeks. It's a reef break, exposed to the swell, and it's mainly going to be one for the experienced crew.
The first few days are a bit of a write-off, honestly. We’ve got some bumpy conditions from the 29th of August right through to the 31st, with a moderate breeze messing things up. There’s some energy in the water – a combined energy of 522 to 1338 – but the wind direction is cross-off or cross-on, and the surf is described as "marginal". Not worth paddling out for.
Now, Tuesday the 1st of September is where it starts to get interesting. The morning is looking clean with a light breeze and a cross-off wind. Swell is 7 ft from the SW with an 11-second period, packing a moderate energy of 1193. This is described as excellent for experienced surfers. The afternoon is a bit windier but still clean, with a bigger 8 ft swell and a longer 13-second period. The crowds are "sometimes", so you might have a few friends out there with you. The water temp feels about average for this time of year.
Wednesday the 2nd of September morning sees a jump in size: 12 ft from the SW with a 13-second period and a combined energy of 4057 – that’s a lot of power. But it’s onshore wind with a "Slight air" state, so the condition report is unknown. This is only for the experts, but the wind is a worry. The afternoon on the same day turns poor with a fresh onshore breeze.
From Thursday the 3rd through Friday the 5th, the conditions turn poor – onshore winds, rain, and lumpy seas. The swell is still there, but it’s just not rideable for a surfer.
Then, hold onto your board for Sunday the 6th of September morning. The wind swings to a cross-off from the NNW with a light breeze, and the waves are clean. The swell is 8 ft from the E with a 9-second period, and a combined energy of 2232. This is another one flagged as excellent for experienced surfers. This is the standout of the entire forecast. It’s a solid, powerful wave with clean conditions. After that, the wind and swell start to mix up again.
The second week gets patchy. There are gaps of a few days where it’s all onshore wind and poor conditions, like the 7th and 8th of September. Thursday the 11th of September morning brings in a long-period groundswell from the SW at 16 seconds, 5 ft high, with a fresh cross-off wind. It’s clean, but described as marginal. Saturday the 13th of September morning has a big 10 ft swell from the SW with a 14-second period and a combined energy of 3886, but it's cross-on and choppy. That kind of power on a beach break could be more interesting for the kite surfers than us paddlers.
Overall, the best bets are Tuesday morning, September 1st, and Sunday morning, September 6th, for the experienced crew at Magna Tubes. Keep an eye on that Sunday; with light offshores and a solid swell, it could fire.
Rusty.

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