The Lowdown
Right, listen up. Rusty here, with the outlook for Magna Tubes.
Alright, so the next week and a half is a bit of a mixed bag here. We’ve got some solid pulse swings, but a lot of it comes with messy wind. The standout window is the morning of Wednesday the 2nd, but if you’re looking further out, the morning of Monday the 14th has some promise with cleaner conditions, though it’s a bit smaller.
The first decent chance is Monday afternoon on the 31st of August, but honestly, it’s poor. Tiny wave energy, only 123 (weak), with cross-onshore wind. Not worth paddling out for. We wait.
Tuesday the 1st of September morning has some size – 8ft from the SW, period 12 seconds (good groundswell) – and the energy jumps to 1553 (moderate), but it’s still cross-on. Afternoon is similar at 8ft, 2125 energy, but again, cross-on. These are marginal, maybe with questionable tides. Not the moment.
Now, Wednesday morning the 2nd is the real deal. This is your best bet. Clean, cross-off wind (5 km/h from the SW), with a solid 10ft SW swell from the optimum direction at a juicy 13-second period. The energy is pumping at 3608 (very strong). This is excellent for experienced surfers – too big for beginners at over 8ft. The break is fairly consistent, but Magna Tubes can see crowds sometimes, so get in early. The water temp anomaly is a huge minus 3°C, which is very unusual; it’s much colder than average for this time of year. The afternoon on the 2nd turns to onshore garbage.
Thursday morning the 3rd is still decent – 8ft, SW, 13s, with clean cross-off wind and 1786 energy – but it’s not as clean as the day before. The afternoon goes to hell with a 30 km/h cross-on.
From Thursday afternoon, right through to Sunday the 6th, it’s blown out with onshore winds, big lumps, and poor surf quality. Sunday the 6th has a massive SW groundswell (18 seconds!) with 6308 energy, but it’s 10ft and onshore. That very long period makes it tricky for a break like this anyway; it’ll be a wall of whitewater. This setup looks more interesting for kite surfing than paddle surfing.
The first week of September is a write-off with strong breezes and messy seas. We get a brief window on Tuesday morning the 8th: 8ft from the E with light cross-shore wind, but energy has dropped to 1093. Only marginal.
The next true standout is Monday morning the 14th of September. Clean, light cross-off wind from the SW, with a 3ft SW swell at 11 seconds. It’s not big, but the energy is 419 (weak) and conditions will be glassy. Again, the water is super cold. After that, Tuesday the 15th sees a bump in size (5ft, SSW, 14s) but fresh cross-off winds keep it clean-ish, though it’s rated as poor.
So, to sum it up: Wednesday morning the 2nd is your heavy hitter for experienced crew. If you want a cleaner but smaller session, Monday morning the 14th is the call. Don't bother with the rest unless you’re a kite surfer or love a beating.
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.
