The Lowdown

G’day, Rusty here. Alright, let’s have a look at what’s comin’ down the pipe for Magna Tubes.

We’ve got a bit of a slow start, but don’t let that fool ya—this place is a proper reef setup that knows how to hold a line when the ocean gets its act together. The water temp is sittin’ around 64.2°, which is a bit colder than normal for this time of year, so you might wanna zip up the steamer just a tad.

The first few days are pretty average. Monday the 27th kicks off with some knee-to-waist high swell from the SW, but that cross-off wind is howlin’ at 22 mph, makin’ it a messy affair. The combined energy is weak at 1684, and it’s just not worth paddlin’ out unless you’re desperate. That afternoon, things get worse—10.0 ft from the SW but with a choppy cross-on, and a score that’s a flat zero. Tuesday the 28th and Wednesday the 29th are similar stories: waist-high swell, onshore winds, and nothin’ clean. The energy stays low, around 1500-1800, and the period is short, so the waves are crumbly.

Thursday the 30th brings a slight improvement. Mornin’ sees a 5.9 ft SW swell with a light 3 mph cross-on, almost glassy. The energy is still moderate at 1508, but it’s workable if you’re keen. Friday the 31st and Saturday the 1st of August are a write-off—strong onshore winds and short-period E swell makin’ for a choppy mess. The energy drops to around 900-1000, and the quality is poor.

Now, Sunday the 2nd of August is where we start to see a flicker. Mornin’ has a 5.6 ft E swell with a light cross-shore wind, and the period is up to 9 seconds. It’s still marginal, but the combined energy is 1109, and there’s a bit more shape. The afternoon sees a 3.9 ft SSW swell with a 16-second period, which is a groundswell, but the wind is onshore, so it’s not quite there yet.

Here’s the standout: Monday the 3rd of August. Mornin’ is glassy—winds are dead calm. The swell is 6.2 ft from the SW with a 13-second period, and the energy is moderate at 1452. This is the first real moment of the outlook. The reef will be workin’ with clean, lined-up waves. It’s not huge, but for an advanced break, this is solid. The water is clean, and the wind is non-existent. If you can get out there, it’ll be worth it.

The rest of the first week is a mixed bag. Tuesday the 4th of August gets hammered by a near-gale WSW wind at 31 mph, with a weak 5.2 ft E swell (689 energy). That’s a no-go. Wednesday the 5th of August has a bigger 9.8 ft SW swell in the mornin’, but it’s cross-off wind and only marginal. The afternoon, though, is clean with a 8.2 ft SW swell and a light offshore breeze. That’s a good one for experienced surfers—the energy is up to 1898, and the period is 11 seconds. The reef will be holdin’ well.

The real standout for the whole outlook: Thursday the 6th of August. Mornin’ has a 6.2 ft SW swell with a 16-second period and a light offshore wind from the W. The energy is 2243, and the waves will be clean, long, and powerful. This is a classic Magna Tubes day—advanced surfers only, but the quality is top-notch. The afternoon gets even bigger, with a 11.5 ft SW swell and a 15-second period, but the wind is light cross-shore. The energy jumps to 5784, so it’s strong, but that big swell might be too much for anything but the most experienced.

The second week keeps the swell alive. Friday the 7th of August through Sunday the 9th of August sees solid 9.8 ft to 11.5 ft SW swell with cross-off winds. The energy is strong, between 4500 and 5500. The best of that stretch is Sunday the 9th of August, with a 11.5 ft SW swell and a 15-second period, and a light offshore wind from the W. The morning is clean, and the energy is 4471. That’s a big, serious day for the experts.

Monday the 10th of August still has the 11.5 ft SW swell, but the wind is cross-on, so it’s messy. The energy is 4785, but the quality drops. Tuesday the 11th of August is smaller, with a 8.2 ft SW swell and a light cross-shore, but it’s just marginal.

Bottom line: the first few days are a write-off. The best on offer is Monday the 3rd of August for a smaller, glassy session, and Thursday the 6th and

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.
