The Lowdown
Right now, the ocean’s got a bit of a split personality. We’ve got some proper swell on the radar, but the wind’s going to be a pain in the neck for a few days before we score some clean ones. Hold on to your boards, it’s going to be a bumpy ride before things glass off.
Magna-Tubes (Magna Tubes), the reef is the only game in town, and for the first stretch, it’s going to be messy. Tuesday the 15th has a weak, cross-on breeze with 5ft of short-period slop. The energy is weak (850) and the water’s a very unusual 61°, which is much colder than normal for this time of year. It’s pretty tough going.
The 16th through the 19th is a write-off for decent waves. We’ve got a solid pulse of 10ft south-west swell filling in, but it’s riddled with strong cross and onshore winds. It’s lumpy, choppy, and just plain ugly out there. This is when the spot is going to be a mess. The 19th afternoon does show a tiny light at the end of the tunnel with the wind going glassy and 7ft of east swell, but it’s a fleeting moment.
Then, we finally get a proper window. The 20th is the first real standout. The wind goes light and glassy in the morning, with a clean 7ft of south-west groundswell wrapping in. The waves are going to be proper, with good shape. This is the one to point the car at if you can. The 21st is a step down in size and a step up in wind, so that’s a wash.
After a couple of small, weak days (22-23 Sep) with the energy dropping out, it’s time for the main event. The 24th isn't great, with strong winds, but it's all building toward the weekend. The 26th and 27th are when the real power arrives. We’re looking at a solid 12ft of south-west groundswell, and on the 27th the winds finally clock offshore and stay clean. The energy is strong (4705), and the sets will be long and lined up. This is the biggest and best of the run. The 28th marks a slow decline, and by the 29th and 30th, it fades back into the messy category.
For a break like this, especially with that long-period groundswell, the shape will be best on the reef. The beachies will be closing out. It’s expert-only territory when it’s over 8ft, so the 26th and 27th are strictly for the chargers.
There is a window on the 25th, with a massive drop in swell and glassy conditions, but it's short-lived.
So, two words: 20th and 27th of September. Mark them in the calendar, but be prepared for the 27th to be big and powerful. The rest is a waiting game.

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.
