The Lowdown

Alright folks, Rusty here. Let’s have a look at what Magna Tubes has in store for us over the next couple of weeks.

We’ve got a bit of a slow start, but some serious potential later on. The first couple of days are a write-off with onshore winds and messy conditions, so don’t bother paddling out just yet. The real interest kicks in from Saturday morning, the 15th, and then again on Monday the 17th. The standout window is shaping up to be Monday morning, the 17th of August. That morning we’ve got a clean 6ft SW groundswell with a 14-second period, glassy conditions, and the combined energy is strong (1282). This is the best of the run—crisp, powerful, and all for experienced surfers. The swell direction is a solid match for the optimum SE direction for this reef, so expect some nice lines. The water temp is about average for this time of year.

Saturday morning, the 15th, is a close second. It’s a little smaller at 4ft from the SW, but the period is still a solid 14 seconds and the wind is glassy. Energy is moderate (699), so not as punchy as Monday, but it’ll be clean and fun.

After that, things get a bit dicey. Sunday the 16th drops right off, and Tuesday the 18th is flat. From Wednesday the 19th, we start seeing some bigger swell—8ft to 8ft SW groundswell—but the wind is cross-off to cross, and conditions are marginal. That’s expert territory, and the crowd factor is a real possibility here (crowds are “sometimes”), so be ready to share if you’re out there. The period is solid (11-12 seconds), but the energy is strong (1573-1564). Not a standout, but worth a look if you’re advanced.

The end of the run has some promise. Wednesday afternoon the 26th looks glassy with a 5ft E swell (11-second period, moderate energy at 568), and Thursday morning the 27th has clean 4ft SW groundswell (14 seconds, moderate energy at 701). Both are smaller but clean, and could be good for a sneaky session.

There’s a big gap of poor conditions from the 16th to the 19th, and again from the 20th to the 22nd. If you’re not keen on the big stuff, hang tight for the cleaner smaller windows later in the second week. The best bet? Monday morning the 17th. That’s the one to circle on the calendar.

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.
