The Lowdown
G’day, Rusty here.
Alright, let’s have a look at what’s on the cards for Magna Tubes. This is a reef break that needs a solid SE swell direction to really fire, and we’re not getting that. The setup is an advanced-level wave, and it’s fairly consistent, but the whole 16-day window is a bit of a mixed bag, with a lot of cross and onshore wind messing things up. The water is sitting at a chilly 58°, which is a massive 8° colder than normal for this time of year – that’s a proper cold snap, so don’t forget the thickest wetsuit you’ve got.
We start off with a real gap. The first few days are a write-off. Friday the 7th has an 8ft SW swell but the wind is onshore and the conditions are poor. Saturday the 8th is a bit cleaner with a cross-off breeze, but the swell is still 8ft and the quality is only marginal. Sunday the 9th morning looks promising at first glance with an 12ft SW swell and offshore wind, giving a moderate offshore and clean look, but it’s a bit of a beast. The wave energy is strong (4170), and at that size, it’s expert-only territory. The problem is, the wind swings around to a strong cross-shore in the afternoon, and the whole thing turns to chop.
The whole first week is a struggle. Monday and Tuesday have a solid 10ft to 10ft SW swell, but it’s cross-shore onshore with rain, and the scores are low. The energy is still moderate to strong (2296 to 2744), but the wind is just not playing ball. We get a bit of a break on Wednesday the 12th, but the swell drops to under 3ft with a very long 22-second period. That’s a groundswell, but it’s a bit too straight for this break, and the cross-onshore wind makes it choppy.
The real standout, the one you’ve been waiting for, is shaping up for Tuesday the 18th and Wednesday the 19th. Tuesday morning the 18th, the wind goes glassy, a total flat calm. The swell is 5ft from the SW with a 12-second period, and the energy is moderate (1059). The conditions are described as excellent for experienced surfers. That’s the one. Then Wednesday morning the 19th, it’s glassy again, with a bigger 6ft SW swell and a 13-second period. The energy is a bit stronger (1186), and it’s still described as excellent. These two mornings are the clear picks – clean, glassy, and a decent size.
Later in the window, we get another interesting one on Friday the 21st afternoon. The wind goes cross-offshore and light, and the swell jumps back up to 10ft from the SW with a 12-second period. The energy is strong (2961), and the conditions are clean, but it’s big. Only for experts.
So, to wrap it up: the first week is a write-off with poor wind and messy conditions. The best bets are the glassy mornings of Tuesday the 18th and Wednesday the 19th, with clean 5ft to 6ft waves. The very end of the window on the 21st could be a big-wave session for the experts if the wind holds. The water is unusually cold, so be prepared for that.
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.
