The Lowdown
Alright, let’s switch to feet and Fahrenheit, same story.
We’ve got one spot on the board for the full 16 days: Magna Tubes. It’s an advanced reef break, not for the faint of heart, but there are a couple of windows that’ll get the blood pumping.
First few days are a bust. On the 6th, there’s a big 12ft SSW swell with a long 18-second period and strong energy (7745), but the east wind is blowing 25 km/h onshore. Water temp is 61°, which is 5° colder than normal – that’s a big anomaly, so you’re in for a cold one.
The 7th is still blown out. Skip it.
Tuesday the 8th morning is the real highlight. Swell drops to a clean 4ft from the SW with a 13-second period, and the wind goes glassy – just 5 km/h from the NNW. Combined energy is moderate at 1122. For the advanced crew, this is going to be clean, punchy, and well-shaped. Best session of the whole outlook.
Tuesday afternoon fades fast. Wednesday the 9th morning is clean but tiny at 2ft.
The 10th afternoon brings a 6ft SW swell with a very long 17-second period (groundswell), but the wind is cross-onshore and choppy. Marginal.
Sunday the 13th afternoon is another standout: 6ft from the SW, 14-second period, and clean offshore wind from the WNW at just 5 km/h. Glassy and hollow for the experts. Combined energy is strong at 2255.
From the 14th onward, solid swell sticks around but wind often spoils it. The 14th morning has a 5ft E swell with an 11-second period and light cross-offshore wind – very good, clean. The 19th Saturday morning shapes up with 5ft from the SE, light cross-offshore, clean.
The 17th and 18th are onshore mess – big waves but poor conditions, more for kites.
The 20th and 21st have consistent 6ft to 7ft SW swell with clean cross-offshore winds and moderate energy. Solid, clean, rideable.
Standout is the morning of the 8th – glassy, clean. The 13th afternoon is a close second if you can handle the size. Crowds are possible at Magna Tubes, and it’s a reef that demands respect.

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.
