The Lowdown

G'day, I'm Rusty, and I've got a look at what's coming up at Magna Tubes. This is a solid reef break that takes a south-east swell and really fires when conditions line up. It's a wave for the experienced crew, so if you're not comfortable on a steep, powerful reef wave, give this one a miss.

The water temperature is sitting at 52°F which is a massive 14°F colder than usual for this time of year. That's far colder than usual, so you'll need a thick wetsuit, booties, and gloves for sure.

First up, we've got a bit of a slow start. Friday the 14th and Saturday the 15th are on the small side, with some lumpy cross-shore wind on the Friday and the swell dropping away. The real action starts to build from Sunday the 16th.

Sunday morning the 16th is the first real standout. We've got a clean 5ft swell from the south-west, with a period of 12 seconds, and the wind is a sweet offshore from the west-north-west. The combined swell energy is moderate (818). This is a glassy, workable wave that will have some punch. The afternoon hangs in there, staying clean, but the wind flicks cross-offshore, making it a little less perfect.

Monday the 17th is where things get serious. The swell jumps up to 8ft from the south-west with a 14-second period. The combined energy is very strong (2272). Morning winds are a clean cross-offshore from the west-south-west. This is excellent surf for experienced surfers. It's a big, powerful wave for the confident crew.

Tuesday the 18th morning is the pick of the week. The swell is a solid 7ft from the south-west, 13 seconds of period, and the wind is a dead-flat glassy calm. The combined energy is strong (1477). These conditions are about as good as it gets for a reef break. The afternoon gets messy with a strong onshore wind, so get in early.

Wednesday the 19th keeps the swell up around 8ft, and the morning is clean with a cross-offshore breeze. This is another one for the advanced crew, with plenty of energy in the water (2010). The afternoon stays clean, but the swell drops a touch.

Thursday the 20th has a smaller 6ft south-west swell, but the morning wind is a light cross-onshore, so it's not ideal. The afternoon is the go, with a clean cross-offshore breeze and good energy (1205).

Friday the 21st is a drop-off day, with the swell fading and the wind picking up. Not worth getting excited about.

Now, hold on to your board, because Saturday the 22nd is a whole different story. We're looking at a massive 16ft to 20ft south-west swell arriving with a very long period of 16 seconds. The combined energy is off the charts (16386). This is a deep-water, big-wave event. The wind is cross-offshore, but the swell is predicted to be too big for this break. This is strictly for tow-in crews or the absolute elite. For anyone else, just watch from the cliffs.

Sunday the 23rd is still huge, with a 15ft to 13ft swell from the south-south-west, but the wind is onshore, so it's going to be a bit of a washing machine. The energy is still enormous (10891).

The wave drops back to a more manageable, but still big, 12ft on Monday the 24th and Tuesday the 25th morning. The wind is onshore for Monday, making it messy. Tuesday the 25th afternoon is a good one, with the swell back to 8ft, a clean cross-offshore breeze, and excellent conditions for experienced surfers (1878).

Wednesday the 26th and Thursday the 27th see another pulse of 10ft to 12ft south-west swell, but the wind is either onshore or cross-offshore with a fresh breeze, so it's not the cleanest. The energy is still strong (3067).

The final days of the month, from the 28th, see the swell fade away and the wind goes onshore, leaving us with poor, small, choppy waves. The 29th is a complete write-off.

The absolute standout window is the 18th morning, with that glassy 7ft swell. The 17th and 19th mornings are also excellent for the advanced crew. Good luck, stay safe in the water, and remember – it's a reef, so know your limits.

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.
