The Lowdown

Alright folks, Rusty here. Let’s break down what’s coming our way for Magna Tubes. This is a reef setup that needs a specific SE swell to really fire, and we’ve got a bit of a slow start before things get interesting.

The first few days are a write-off. Saturday the 1st and Sunday the 2nd are messy with cross-onshore winds and a short-period, weak E swell that’s just not doing the job. The water temp is about average for this time of year, so no surprises there. Monday the 3rd is still marginal, with a light cross-shore breeze but the swell is small and not very powerful.

We start to see some cleaner conditions on Tuesday the 4th with a cross-offshore wind, but the swell is only 4 ft and from the SW – not the ideal direction for this spot. Wednesday the 5th morning has a tiny 3 ft E swell with clean conditions, but it’s just not enough to get excited about.

Now, Thursday the 6th is where it gets real. A big SW groundswell pushes in, hitting 16 ft on the morning with a 12-second period. The combined energy is massive (7148), but that’s storm surf – it’s gonna be a washing machine. The wind is cross-off and clean, but for the average surfer, this is too big. Only for the experts.

The standout window, and I mean the real standout, is Sunday the 9th. The morning brings a 16 ft SSW swell with a 10-second period, and cross-offshore winds from the W. The energy is pumping (5471), and the conditions are described as exceptional for expert surfers. This is the one to circle on the calendar. It’s a long way out, so keep an eye on it, but if it holds, Magna Tubes will be a beast.

After that, Monday the 10th and Tuesday the 11th morning are a mess with strong onshore winds and a massive, disorganised swell. But then, Tuesday the 11th afternoon... glassy conditions, a 18 ft ESE swell with a 12-second period, and the energy is still huge (8343). The report says it's exceptional for experts. That’s a serious session if you’ve got the skills.

The rest of the second week looks cleaner with smaller, more manageable surf. Thursday the 13th has a solid 10 ft E swell with clean cross-offshore winds, and Friday the 14th morning is glassy with a nice 6 ft E swell. The weekend of the 15th and 16th drops off to smaller, cleaner waves – a 4 ft glassy morning on Saturday the 15th and a 4 ft SW swell on Sunday the 16th with clean conditions. Good for a longboard.

So, the best of the best? It’s Sunday the 9th morning for the big, powerful, and clean swell, and Tuesday the 11th afternoon for the unexpected glassy gem. Don’t sleep on Thursday the 13th either for a solid, clean day.

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.
