The Lowdown

Alright, Rusty here. Let's have a look at what's coming up for Magna-Tubes.

Right off the bat, we've got a solid window of swell but the conditions are a real mixed bag for the first week and a half. The water's sitting at 56°F, which is a massive 10°F colder than usual for this time of year, so bring all the rubber you own.

The first real action that catches my eye is on Monday, August 24th. The morning session is looking clean with a 7ft SW swell and a light cross-off breeze. The combined energy is moderate at 1125, and it's got that excellent surf condition tag for experienced surfers. That afternoon, it's still rideable but a bit windier.

Now, the real standout, the one you want to circle on the calendar, is Tuesday morning, August 25th. We've got a 10ft SW swell, a period of 14 seconds, and the wind is glassy. Absolutely glassy. The combined energy is pumping hard at 3427, and it's flagged as excellent for experienced surfers. This is a big, powerful groundswell with clean conditions. It's going to be a dynamic session, but with that size, it's strictly for the crew who know what they're doing.

After that, the surf drops off and the wind gets messy. There's a long gap of poor to marginal conditions until Thursday afternoon, August 28th, where we get a little 4ft S swell with glassy winds again, but it's small.

Then, we skip ahead to the long-range forecast. The real monster is lurking on Thursday, September 3rd. The morning is looking at a massive 18ft SW swell with a 14-second period, clean cross-off winds, and a combined energy reading of 11949 – that's exceptional. This is a once-in-a-while kind of swell for experts only. The following morning, Friday, September 4th, is also a standout with a 15ft SW swell and glassy conditions. Keep in mind, this is a long way out, so it's promising but not locked in yet.

So, to sum it up: the best windows are Monday morning the 24th but the absolute highlight is Tuesday morning the 25th for a big, clean session. Then, keep an eye on that massive swell around the 3rd and 4th of September.

Stay warm and stay safe out there.

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.
