The Lowdown

Alright folks, Rusty here. Let’s get into it.

Well, the first big news is the water temperature. For Magna Tubes, it’s sitting at 55°F – that’s a whopping 11°F colder than usual for this time of year. That’s seriously unusual, so you’ll want the thickest rubber you’ve got. Don’t even think about a spring suit.

The real standout, and I mean the absolute gem of this whole 16-day window, is Thursday morning, August 20th. The swell is pumping at 13ft from the SSW with a solid 14-second period, giving us a massive 6059 (strong to very strong wave energy) in the water. The wind is a clean cross-off from the WSW at 9 mph. This is a reef break for advanced surfers only, and at that size, it’s going to be a freight train. Don’t even look at it if you’re not an expert. This is the one to circle on the calendar.

The rest of the first week is a mixed bag. Thursday afternoon drops to 12ft, but the wind goes cross-shore, making it less ideal. Friday morning, August 21st, has a clean 8ft, but the wind is a light cross-onshore, putting a little ripple on the face. By Friday afternoon, the wind cranks onshore at 16 mph and the surf turns to junk. Saturday and Sunday are blown out by strong winds, though Sunday morning, August 23rd, offers a moment of pure glass with 8ft from the SW. That’s worth a paddle if you can dodge the crowds that are *possible* here.

The following week is a bit of a lull with inconsistent quality. Tuesday, August 25th, has a decent 8ft from the SW with a 14-second period, but the wind is a choppy cross-onshore from the East. The energy is still decent at 3489 but the wind is a bummer. The mornings of August 26th and 27th offer clean, smaller surf in the 4ft to 5ft range, but it’s a lot smaller than the opening blast.

Now, hold onto your boards, because the second week gets interesting again. On Wednesday morning, September 2nd, we get a clean 8ft from the SW with a 15-second period, and the energy is strong at 2673. But the real beauty of that day is the afternoon: glassy conditions, 10ft from the SW, and even stronger energy at 3598. That’s a top-tier window for the experienced crew.

Then on Thursday, September 3rd, the swell jumps back to 13ft from the SW in the morning, but the wind is onshore from the ESE, which will ruin the shape. The following Friday morning, September 4th, looks clean again with a solid 8ft from the SW and a 13-second period, making for a great, clean finish to the outlook.

Overall, the first Thursday morning and the Wednesday afternoon of September 2nd are your best bets. It’s a long-range call for that September swell, but the signs are promising. Get out there.

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.
