The Lowdown
Alright, Rusty here, checking in from the water’s edge.
We’ve got a bit of a slow start, but things are about to get spicy at Magna Tubes. This spot’s a reef setup, so it’s for the advanced crew only. Right now, the water is a bone-chilling 55.6°, which is 10.4° colder than usual for this time of year – that’s seriously unusual, so you’ll want a thick suit.
The action kicks off Tuesday morning, the 25th of August. It’s a bit messy with a 12.4 mph cross-offshore wind, but we’ve got a solid 8.2 ft swell from the southwest. The energy is pumping at 3463 (moderate to strong), and the period’s a decent 13 seconds. It’s not perfect, but there are waves to be had. By Tuesday afternoon, that same 8.2 ft swell cleans up nicely with a lighter 6.2 mph cross-offshore breeze and a longer 14-second period, dropping the energy a touch to 3029. This is your best early call—clean, powerful lines for the experienced.
Wednesday the 26th is a complete write-off. A 9.8 ft swell from the south-southwest turns into a choppy mess with onshore winds hitting 21.7 mph. Don’t even look at it.
Then, Thursday the 27th morning is the true standout. We’ve got glassy conditions—wind is 0 mph—and a clean 6.9 ft south-southwest groundswell with a 12-second period. The combined energy is 1951 (moderate). This is the kind of morning you dream about: no wind, solid swell, and the reef will be offering up some proper shaped waves. It’s the best on offer in this whole run. The afternoon drops off to 4.6 ft.
Friday the 28th and Saturday the 29th are fun, smaller days. Friday morning has a 4.6 ft east swell with 6.2 mph cross-offshore winds—clean and surfable. Saturday morning drops to 3.6 ft but with a clean 6.2 mph offshore wind from the west-northwest. Nothing huge, but good for a cruise.
We’ve then got a long run of small to moderate surf through until the end of August. There’s a bit of a pulse on Monday the 31st with a 5.9 ft south-southwest swell and 9.3 mph offshore wind, but the period is a short 9 seconds, so it’ll be a bit walled up.
The next real standout is on the 2nd of September—Wednesday morning. This is a big one. We’ve got an 11.5 ft southwest groundswell, 14-second period, and a light cross-offshore breeze. The energy is 5117 (very strong). This is a legit, expert-only session. The wave faces will be chunky and powerful. Wednesday afternoon sees the wind jump to 31.1 mph, so get it in the morning or miss it.
After that, the forecast gets a bit messy with a lot of marginal days through the 3rd, 4th, and 5th of September. An 11.5 ft swell returns on the 4th but with cross-shore and onshore winds killing the quality.
The last week has a few glimpses. The 7th of September Monday morning offers a 4.9 ft south-southwest swell with 9.3 mph cross-offshore winds—it’s clean but not powerful. From there, it fades into small, wind-affected surf right through to the 9th.
So, to sum it up: jump on Thursday the 27th of August morning for the glassy perfection at Magna Tubes. The true big-wave crew should target Wednesday the 2nd of September morning for that 11.5 ft groundswell. Get out there and get wet.

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.
