The Lowdown
Alright folks, Rusty here. Let’s get into it. We’ve got a wild sixteen-day window ahead at Magna Tubes, a proper reef setup that demands respect. The overall pattern is building from a slow start into a serious pulse of energy, with a massive standout waiting for us at the very end. There’s a bit of a gap at the beginning here, so don’t rush out the door just yet.
The first real chance kicks off on Monday the 20th of July. It’s a mellow start with a 4ft swell from the southeast, and a 12-second period. The water is sitting at 63°, which is a bit colder than normal for this time of year. The wind is a cross-off, but honestly, the energy is weak (639) and the conditions are just marginal. Not worth the paddle.
Tuesday the 21st is where it starts to get interesting. Tuesday morning brings a glassy, dead-calm session with the wind swinging to the southwest. Swell jumps to 6ft from the southwest with a 15-second period, and the energy is pumping at 1756. This is a clean, excellent window for experienced surfers. The period is long, so the reef will handle it beautifully. Tuesday afternoon turns onshore and messy, so make the morning session.
Wednesday the 22nd and Thursday the 23rd keep the solid 7ft to 7ft SW swell rolling, with periods around 12 seconds. Thursday morning is the pick of these two days: a clean, gentle offshore wind from the WNW, with a nice 1944 energy reading. The swell is over 6ft, so this is expert territory.
Then we hit a big, messy, and powerful run from Friday the 24th through Sunday the 26th. Friday morning sees a 13ft SSW swell with a 16-second period – the energy is a massive 8179 – but it’s cross-on and cloudy. The size is huge, the period is very long, and the wind is wrong. For a beach break this would be a kite-surfing show, but on a reef, it’s just dangerous and sloppy. Friday afternoon and Saturday afternoon are blown out or onshore.
Saturday the 25th morning is a bright spot: 8ft SW swell, 14-second period, glassy winds, and a strong energy reading of 2758. This is a clean, excellent window, but the swell is over 8ft, so only experts need apply.
The next week stays active, with a lot of 8ft to 10ft SW swell, but the wind is often moderate to fresh cross-off or cross-shore, keeping the quality marginal. There’s a small window on the morning of Thursday the 30th of July with a 7ft SW swell and light cross-shore wind, but it’s nothing to write home about.
Now, the standout. The absolute highlight of the whole forecast is Saturday the 1st of August. This is the one. We’re looking at a massive 20ft SW swell on the morning, easing to 18ft in the afternoon. The period is 14 to 13 seconds, and the wind is a light to gentle cross-off from the WSW. The combined energy is a staggering 12494 in the morning and 9397 in the afternoon. This is exceptional, expert-only surf. The reef will be working, but this is big, dangerous, and powerful. If you’re not an expert, stay on the beach. This is the best on offer, bar none.
Sunday the 2nd of August sees a drop in quality with a 15ft S swell and onshore cross-on winds, turning poor. The following Monday the 3rd and Tuesday the 4th of August offer a return to cleaner, smaller conditions with 8ft to 12ft ESE to E swell, and manageable cross-off winds. The period drops to 10-12 seconds, so it’s less powerful, but still solid for experienced surfers.
Overall, the big prize is the 1st of August. The rest is a long run of solid, powerful surf that will take a keen eye on the wind to find the clean windows. The crowds at Magna Tubes can be a thing sometimes, so be ready for company on the peak days.

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.
