The Lowdown
Right then, let’s have a look at what’s on offer over the next couple of weeks. It’s a bit of a mixed bag, if I’m honest, with a rough start but some real promise if you’re patient.
Right now, Monday the 10th, the swell is actually there at Magna-Tubes – we’re looking at 8 ft from the SW with a period of 12 seconds and a cross-on wind, so it’s messy. The water is a frigid 58°, which is 8° colder than normal for this time of year, so that’s very unusual. You’ll need a thick hooded suit for sure. The combined energy is a hefty 1862, so there’s plenty of push, but the quality is poor. That sets the tone for the first few days, honestly.
Tuesday the 11th sees the swell easing a bit, 8 ft on the morning and 6 ft in the afternoon, but that easterly wind just ruins it. Wednesday the 12th is even worse – the swell is small but messy, with a 19 mph cross-on wind. Not a time to be out there unless you’re keen on a beating.
We finally get a glimmer on Thursday the 13th morning. The swell picks back up to 5 ft from the SW, the period stretches to 16 seconds, but it’s still a cross-on wind, and the energy is massive at 2573. It’s marginal at best.
Friday the 14th is where it starts to turn. That morning session is the first real standout. We’ve got a clean 5 ft SW swell coming in at 16 seconds, with a light cross-offshore breeze from the north. The combined energy is 1917, so there’s plenty of grunt. The water temperature is still cold, but the conditions are clean and excellent for experienced surfers.
Saturday the 15th stays clean but the swell drops a little to 4 ft. It’s not a standout, but it’s a decent small-wave option.
Now, the big one hits on Monday the 17th afternoon. This is the best of the forecast. We’re looking at 8 ft of SW groundswell with a 16-second period, and the wind is a light cross-offshore from the southwest. The combined energy is 2982. It will be big, powerful, and clean – keep in mind that long period swell can break a bit straight at beach breaks, but at a reef like Magna-Tubes, it should be firing. This is for experienced surfers only.
Tuesday the 18th is a great follow-up. The morning is clean with a 7 ft SW swell and a light cross-offshore wind. Energy is still strong at 1928.
From Wednesday the 19th, it goes flat and messy again for a few days with rain and strong onshore winds, especially Thursday the 20th with winds hitting 25 mph. Not worth paddling.
Then we see another potential on Saturday the 22nd morning. It’s a clean 6 ft from the SE with a light cross-offshore breeze. The period is a shorter 9 seconds, but the conditions are good. The energy is moderate at 866.
The 16-day window closes out with a massive pulse on Monday the 24th and Tuesday the 25th. We’re talking 10 ft to 12 ft of SW swell, with very high combined energy over 4000. Unfortunately, the wind is onshore or cross-onshore, making it messy and dangerous. That’s one for the experts only in a chase boat.
In short: don’t bother until Friday the 14th morning for a small clean wave. The absolute standout is Monday 17th afternoon and Tuesday 18th morning. After that, keep an eye on Saturday 22nd morning. The rest is a write-off.

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.
