The Lowdown
Alright folks, Rusty here. Let’s get stuck into what’s coming up for Magna Tubes.
Alright, we’ve got a solid run of surf ahead, but it’s not all clean. The first week is a bit of a mixed bag with some powerful, groundswell energy but often messy wind. The real standout window is the second weekend and into the following week when the winds finally play ball.
We kick off the first recommendation on Friday, August 7th. The morning’s got a solid 10ft SW swell pumping in, with a long 13-second period, giving it some serious grunt. Combined energy is a massive 2490, so there’s a ton of power. But the wind is from the ENE at 6 mph, so it’s a cross-on breeze, making it a bit lumpy. It’s a marginal shout for the advanced crew only, given the size and the chop.
Friday afternoon, the wind picks up hard to 16 mph, and it’s choppy as hell. That’s a write-off.
Saturday the 8th is a different story. The wind swings WSW and goes cross-off, cleaning up the face. The swell is still a meaty 8ft from the SW (14-second period), with energy at 2545. It’s still big and powerful, but the clean conditions make it a much better prospect for the experienced surfer. That clean look holds through Sunday morning, with the swell even bigger at 11ft (3931 energy). That’s proper big, expert-only territory, but with the wind clean, it’s a serious session for those who can handle it. Sunday afternoon goes to crap again with rain and onshore wind.
Monday the 9th through Friday the 14th is a week of frustration. The swell hangs around, but the wind is nearly always onshore or cross-on, creating choppy, lumpy conditions. The energy remains high, often in the 1700-2400 range, but it’s just not clean. There are a few moments of lighter wind, but the wave quality is still marginal.
Now, here’s where it gets good. Friday afternoon, August 14th. The wind drops to zero, and it goes glassy. The swell is a clean 4ft from the SW with a 14-second period, and the energy is a moderate 964. Conditions are described as “expect very good surf conditions.” This is a proper window for a fun, clean session.
Saturday, August 15th, is the absolute standout. Morning sees a 5ft SW swell with a 13-second period and a clean cross-off wind. The score is a 4 out of 10, and it’s described as “excellent surf conditions for experienced surfers.” The afternoon gets even better: the swell bumps up to 5ft, the period stretches to 15 seconds, and the wind is a light cross-off. The energy is 1424. This is the pick of the forecast. The combination of clean, offshore wind and a solid, long-period groundswell will set up some proper lines. The water is about average for this time of year, so no surprises there.
Sunday the 16th morning is still clean with similar swell, but the wind picks up again. The rest of that week is a mix of okay and onshore, though Monday the 17th afternoon has a 6ft SW swell with light offshore wind, which is worth a look.
Then we hit the next real highlight. Tuesday, August 18th, both morning and afternoon are firing. A solid 7ft SW swell with a 12-second period, and a light cross-off wind from the SW. The energy is around 1600, and it’s rated as “excellent surf conditions for experienced surfers.” This is another session to pencil in, with clean, powerful waves.
Friday, August 21st, the afternoon session looks promising too, with a 8ft SSW swell, a 10-second period, and a light cross-off wind. Clean conditions for the experienced crew.
And finally, Saturday, August 22nd, the morning goes glassy again with a 6ft SSW swell. The energy is moderate at 954, but with zero wind, it’ll be a beautiful, clean morning.
Overall, the best surf is on the 15th and 18th of August. The wind is clean, the swell is solid, and the power is there. The crowds at Magna Tubes can be an issue sometimes, but with these conditions, the paddle out might be a bit of a battle, but the rewards will be worth it.

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.
