The Lowdown
G’day, this is Rusty. Look, I’m not gonna sugarcoat it – the next couple of weeks at Magna Tubes are a mixed bag, with a few standout moments that’ll get your heart pumping, but plenty of days where you’ll be better off waxing the roof or the longboard.
The water temp is sitting at 59.0°, which is a whopping 7.0° colder than usual for this time of year. That’s seriously unusual, so you’ll want a thick wetsuit – maybe even booties – if you’re heading out.
We kick off Saturday morning, 29th August, with a small 3.6 ft swell from the east, but the combined energy is only moderate (527). It’s a bit messy, and the wind is a cross-off from the WSW at 9 mph, so it’s clean but not pumping. Honestly, it’s a marginal session at best.
Sunday the 30th looks a bit better. The swell jumps to 7.5 ft from the SW with a period of 10 seconds, and the energy is strong (1081). The wind is cross-off from the SW at 12 mph, keeping it clean. Still, it’s a bit raw and not the best quality.
Monday morning the 31st has a 6.2 ft SW swell with a 12-second period – that’s a nice groundswell – and the energy is strong (1004). The wind is a light cross-on from the SSE at only 3 mph, so small ripples but not blown out. It’s a marginal call, but the long period might make it a bit fat for the beachie; it’s worth a look if you’re keen.
Tuesday the 1st of September brings a 6.9 ft SW swell with an 11-second period, and the energy is charging at 1214. The morning has a light cross-shore from the SSW at 3 mph, so there’s a bit of crossing wind ripple, but it’s still surfable. The afternoon sees the swell bump to 7.5 ft with a 13-second period and energy skyrocketing to 1819, but the wind picks up to 16 mph cross-off from the SW. It’s clean, but that’s a fair bit of juice.
Now, here’s the standout – Wednesday morning, 2nd September. This is the one. We’ve got a solid 11.5 ft SW swell with a 13-second period, and the combined energy is a massive 3909 – that’s very strong, powerful surf. The wind is glassy from the ENE at 3 mph. Absolute perfection for experienced surfers. This is a big, heavy, grunty wave at Magna Tubes, and it’ll be a pack of howling barrels if you’ve got the stones. But be warned – it’s only for experts, and with that size, it’ll be a challenge. The afternoon is a write-off, with onshore ESE winds at 16 mph making it a mess.
Thursday the 3rd has a decent 7.9 ft SW swell in the morning, but the wind is cross-off from the WSW at 9 mph, keeping it clean. The energy is still strong (1962). The afternoon, though, gets smashed by a near gale from the SSE at 31 mph – stay out of the water.
Friday the 4th is a complete no-go with onshore winds and blown-out conditions. Saturday the 5th is marginal at best, with a 5.6 ft swell but cross-onshore winds making it choppy. The afternoon gets a 9.8 ft swell but it’s a choppy mess – that’s more kite-surfing territory.
Sunday the 6th has a 8.2 ft SW swell with a 13-second period, and the wind is cross-off from the WSW at 19 mph, so it’s clean but windy. The energy is 2237 – strong. It’s a solid session for the experienced, but not perfect.
The first week of September is a bit of a rollercoaster, with a lot of windy days and marginal windows, but that Wednesday morning is the real gem.
The following week, we’ve got a bit of a gap in quality. Monday the 7th drops to 4.3 ft, and Tuesday the 8th has a 3.9 ft SW swell with a 16-second period – that’s a very long period groundswell, which can be tricky at a beach break, but the energy is strong (1102). The wind is onshore, though, so it’s not great.
Then we hit another standout on Saturday the 12th of September. Morning brings a 9.8 ft SW swell with a 14-second period, and the energy is a massive 3244. The wind is a light cross-off from the SW at 3 mph – clean and glassy. This is another big day for experts only. The afternoon drops to 3.0 ft with a 15-second period, but the energy is low (410) and it’s clean. Not

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.
