The Lowdown
Alright, surfers, Rusty here. Let’s have a look at what’s on the cards for Magna Tubes.
Overall, the next 16 days start with a bang, but then it gets a little messy. The real standout action is definitely in the first week, with some solid, powerful groundswell rolling in. We’ve got a few promising windows of clean conditions, but you’ll have to pick your moments carefully.
The water is a weird story. At 57°F with a -9°F anomaly, it's far colder than usual for this time of year. You’ll be wanting a thick wetsuit, no doubt about it.
The first real highlight is Thursday morning, the 27th of August. The conditions are absolutely perfect—glassy, with a light offshore breeze from the NE. There’s a clean 7ft swell from the SSW, with a period of 12 seconds, and the combined energy is a solid 1919. This is a powerful, clean wave, but at that size, it’s for the experienced crew only. The break is a reef, so expect a proper, well-shaped wave, though the long period might make it a bit straight at times.
After that, we get a few days of smaller, but still fun, surf. Friday afternoon, the 28th, looks great with a glassy 4ft from the S (11 seconds) and an energy of 889. The crowds are possible here, so get in early. Saturday morning, the 29th, is also a good call with a clean 4ft from the S (11 seconds) and a nice cross-off wind.
Then the swell really starts to pump again. The next big window is Monday morning, the 31st of August. It’s glassy and clean, with a 6ft SW swell (12 seconds) and an energy of 929. Great conditions.
But the real monster is on the horizon. Tuesday afternoon, the 1st of September, sees a massive 13ft SW swell (14 seconds) rolling in, with energy at 5084. The wind is a cross-off, so it’ll be clean, but this is for experts only. The following morning, Wednesday the 2nd, is even bigger at 16ft from the SW (14 seconds), with an incredible 9429 energy. This is serious, heavy, powerful surf. The wind is a strong cross-off, so it’ll be manageable, but this is a big day for the big dogs.
The second week is less consistent and a bit more wind-affected. The surf stays solid, but the wind is often onshore or cross-onshore, making it lumpy. There’s a poor run from the 5th of September, so don’t expect much.
The last real standout is Monday morning, the 7th of September. It’s a fresh offshore wind from the NW, with a 6ft E swell (10 seconds) and an energy of 1289. It’s a marginal call, but the offshore wind will make it clean. The following afternoon also has a nice 4ft S swell (13 seconds) with a light cross-off wind and an energy of 1185.
So, to sum it up: the best days are Thursday the 27th of August, Monday the 31st of August, and the big one on Tuesday the 1st of September. Get on it.
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.
