The Lowdown

Alright, let’s get down to it.

We’ve only got one spot on the radar this whole period: Magna Tubes. It's a proper reef break, and it’s going to be a busy place, but it’s the only game in town. The water is shocking though – 58° right now, which is a full 8° colder than usual for this time of year. This is some serious, bone-chilling water, so you’re going to need all the rubber you can find.

The surf story is a slow burn into a massive climax. We start off with some decent, clean surf. Friday morning the 14th is a great warm-up: a 5ft SW groundswell with a 15-second period, and a light cross-off wind from the N. The energy is moderate but solid (1286). It’s a fun, punchy day for the experienced crew.

The weekend is underwhelming. Saturday morning is glassy but smaller, and Sunday is a complete dud with a weak, short-period swell.

But then the real run starts. Monday the 17th, the swell jumps to a solid 8ft, and the energy has moved into the strong range (2131). Tuesday the 18th is glassy with 7ft of swell and strong energy. This is when it starts to get good.

The apex of this first big pulse is Wednesday the 19th: 8ft of SW swell, holding its period, and light offshore winds. The energy is right up there at 2099, and it's going to be powerful, clean, and grinding. The mornings from the 17th through the 21st are where you want to be, especially with the light winds and glassy sessions.

But the real standout is the weekend of the 22nd and 23rd. This is where it gets biblical. Swell heights jump to 13ft, then 15ft, with energy readings climbing past 5000 and then 7000. This is a true big-wave event. The winds are cross-off, but it won't matter much when the ocean is that angry. This is strictly a big-wave expert zone.

After that, it eases down for a few days, but there’s one more giant lurking at the end of the window. Way out on Saturday the 29th, the forecast is showing an absolutely massive 16ft of SW swell, with a very long 16-second period. The energy is an enormous 13328, and the wind is forecast to be dead calm. This is as good as it gets on paper, a truly epic, world-class swell. But it’s over two weeks away, so don’t book your flights yet. Still, it's one to keep an eye on.

So, there you have it. A month of two halves: a solid, workable swell in the middle, followed by a monster at the end. It's a cold, expert-heavy forecast. Suit up, be smart, and pick your sessions. The mornings are your friend.

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.
