The Lowdown

Alright, Rusty here, let’s break down what’s going on at Magna Tubes.

August starts with a clean pulse of groundswell. On Wednesday morning the 5th, you’ve got a 3-foot swell from the SSW with a 15-second period – that’s long-period groundswell that will wrap nicely into the reef. The water is sitting at 59°, which is 7° colder than normal for this time of year, so you’ll want a thicker wetsuit. The combined energy is moderate at 876, and with a light cross-off wind from the NNW, it’ll be clean. A small but fun session for the longboard.

Wednesday afternoon, the swell jumps to 6 feet from the SW, period 16 seconds, with energy hitting 1782. The wind is light cross-shore from the SSW, but there’s a question mark on the tide.

Thursday the 6th is a big step up. Morning sees 12 feet from the SW with a 13-second period and a massive 4961 energy reading. The wind is clean cross-off from the WSW. That’s big, expert-only territory. The afternoon holds similar size but the wind turns cross-shore and brings a little chop.

Friday morning the 7th is the real standout early on. It’s glassy, with a 10-foot SW swell at 13 seconds and 2823 energy. The wind is from the SSE at 5 km/h – dead calm. This is a top-shelf morning for experienced surfers. The afternoon is a write-off with onshore wind.

Saturday the 8th morning is another cracker: 10-foot SW groundswell, 14-second period, 3062 energy, and a light cross-off wind from the WSW. That’s clean and powerful. It’s the best of the first week, but crowds are possible here.

Sunday the 9th through Tuesday the 11th is a full washout. Strong cross-onshore winds, rain, and blown-out surf. There’s a solid 13-foot swell on Sunday but it’s useless with 50 km/h winds. A total gap of three days of poor conditions.

Wednesday the 12th morning brings a reprieve: glassy conditions, 4 feet from the SSW with a very long 20-second period. The energy is still moderate at 1717. That long period will make it super clean but the sets will be spaced out.

Thursday the 13th morning is glassy again, 6 feet SW at 16 seconds and 2346 energy. That’s excellent and clean.

Friday the 14th is a write-off with onshore wind, and the swell shifts to a shorter-period ESE windswell.

Saturday the 15th and Sunday the 16th see smaller, cleaner waves, dropping to 6 feet and 4 feet, with light cross-off winds. The energy drops off fast – 995 down to 284. It’s fun but not the standout.

Then there’s a flat spell Monday the 17th and Tuesday the 18th, with weak 3-foot and 2-foot swells. The energy is barely 177 and 92. Not worth paddling out.

But then, Wednesday the 19th morning is a hidden gem. 12 feet of SW swell, 13-second period, 3724 energy, and a glassy offshore from the SW. That’s clean and powerful. It’s deep in the forecast, so a bit less certain, but it looks promising.

And then Thursday the 20th – hold onto your board. The morning shows a massive 21-foot SW swell, 14-second period, and an insane 16911 energy. The wind is glassy from the W. But the guidance says it’s predicted to be too big for this break. That’s double-overhead-plus and dangerous. Only the absolute top-tier experts on big-wave guns should even think about it. The afternoon is even bigger – 21 feet with a 15-second period and 34269 energy. That’s a full-on, life-threatening swell. Best left to the big-wave chargers or the kitesurfers looking for a thrill.

All in all, the best on offer is Friday morning the 7th and Saturday morning the 8th for the first week, and then Wednesday the 19th morning for a long-range shot. Early days are the most reliable, but the 19th is the one to watch.

Rusty out.

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.
