The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking at Magna Tubes.
The whole 16-day window is a bit of a mixed bag, with plenty of action but a lot of it comes with tricky winds. The real standout is a solid, long-period south-west groundswell that builds in the second week, with a few windows of absolute perfection.
The first few days are a write-off. Thursday morning (30th July) kicks off with a 6 ft SW swell, but the 9 mph cross-on wind from the ENE makes it a choppy, messy affair. That afternoon and all of Friday and Saturday are just as grim, with fresh onshore winds and lumpy conditions. The swell drops a bit, but it’s not worth paddling out for.
We finally get a glimmer of hope on Sunday morning (2nd August). The swell is 7 ft from the east with a 9-second period, and the wind swings to a light cross-shore from the north at just 3 mph. It’s still a bit marginal, but with the combined swell energy (1476) building, there’s some shape in the water. Conditions improve significantly on Monday morning (3rd August). The swell drops to 5 ft from the ESE, but the wind goes light cross-offshore from the WSW, cleaning things right up. The combined energy (1135) is moderate, and it’s clean and surfable.
Tuesday morning (4th August) is a true beauty. The swell is 5 ft from the SW with a 12-second period, and the wind goes glassy from the WSW. That’s clean, perfect conditions for a reef break like Magna Tubes. The combined energy (927) is moderate, but with the glassy surface, the waves will be peeling nicely. This is a real highlight for the advanced crew.
Then it gets serious. Wednesday afternoon (5th August) sees a jump in the swell to 8 ft from the SW with a very long 15-second period. The combined energy (3100) is strong. With the 12 mph cross-offshore wind, it’s clean but powerful. This is expert territory. The same goes for Thursday morning (6th August) – 8 ft SW at 14 seconds, glassy conditions, and the combined energy is still very strong (2676). Absolutely firing for the experienced surfer.
The absolute peak of the window looks like Friday morning (7th August). The swell hits 10 ft from the SW with a 14-second period, the wind is glassy from the NNW, and the combined energy is a massive 3788. This is a solid, powerful groundswell with perfect conditions. Magna Tubes will be pumping. It’s only for experts, but it’s the best on offer. The afternoon goes a bit cross-on, but the morning session is the one.
From there, the swell stays strong through the weekend, but the wind gets a bit stronger. Monday morning (10th August) is a no-go with gale-force cross-offshore winds at 40 mph and a massive 21 ft ESE swell (11155 combined energy). That’s not for surfing; that’s a serious weather event.
Things settle down again on Tuesday morning (11th August). The swell drops to 8 ft from the ESE, but the wind is glassy calm, with the combined energy (1768) still strong. That’s another excellent, clean session for those who can handle it.
The last few days of the window taper off. Wednesday (12th August) has a 6 ft SW swell with a very long 16-second period, but it’s cross-on. The final decent window is Thursday morning (13th August) with a 5 ft SW swell, light cross-offshore wind, clean conditions, and a combined energy (804) that’s moderate. A nice, mellow end to the run.
So, the standout is hands-down the Friday morning (7th August) session at Magna Tubes. 10 ft of SW groundswell, glassy conditions, and a ton of energy. It doesn’t get much better for an advanced reef break. The Tuesday morning (4th August) and Tuesday morning (11th August) sessions are also top-tier, with glassy or clean conditions, but that Friday is the big one.
The water temperature is 65°, which is about 1° cooler than usual for this time of year, so it’s a little on the fresh side but nothing crazy.
Expect crowds at Magna Tubes, especially when it’s this good. It’s a known spot, and when the swell hits, the lineup will be full.
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.
