The Lowdown

Alright, crew. Rusty here, and I’ve been staring at this one break for the next two weeks—Magna Tubes. It’s a reef, so when the swell hits right, you get that proper shape, and it’s fairly consistent, so we won’t be waiting forever. The water’s at 64°, which is a bit colder than normal for this time of year, so maybe grab a spring suit if you’re a little thin-skinned.

The forecast starts quiet on Tuesday 14 July, with nothing really worth paddling out for. Wednesday morning 15th gives us a tiny 4ft swell from the east at 10 seconds, clean with a light cross-off breeze—fun for a log, but no power. The combined energy is moderate (310), so you’re not getting much push.

Now, the real standout is Thursday morning 16 July. That’s the one. We’ve got a solid 10ft swell from the southwest with a very long 14-second period, and glassy conditions with barely a breath of wind. This is groundswell, and it’s packing serious energy (3233). That’s big, powerful, and clean—only for experienced surfers. The reef will love that long period, so expect some deep barrels. If you’re not comfortable in overhead surf, watch from the rocks.

Friday morning 17 July keeps the energy going with an 8ft swell from the southwest, 12 seconds, and clean cross-off winds. Combined energy is still strong (2015). This is excellent for the advanced crew, but still solid.

Saturday 18 July drops off hard—down to 4ft from the south, 11 seconds, with glassy conditions. The energy is weak (578), so it’s a small, clean day, maybe a good one to recover.

Sunday 19 July bumps back up to 7ft from the southwest, 12 seconds, with clean cross-off winds. Moderate energy (1447). It’s good, but not the standout.

Monday 20 July pushes 8ft from the south-southwest, 11-12 seconds, with light cross-shore winds. Energy is strong (1798-2060), but those winds are a bit messy, so not as clean as earlier.

Then Tuesday 21 July—another absolute cracker. Morning brings 10ft from the south-southwest, a very long 16-second period, and offshore winds from the west at just 6 mph. The energy is pumping (4344). This is world-class quality for experts. The afternoon gets hairy with 13ft and 25 mph winds, so stick to the morning.

Wednesday 22 July is the big daddy. Morning has 13ft from the southwest, 14 seconds, offshore winds from the northwest, and energy at 6818. That’s exceptional—only for the brave and skilled. The afternoon drops to 12ft but stays clean.

Thursday 23 July gets blown out by a near gale (31 mph) in the morning—avoid. Afternoon improves but still moderate.

Friday 24 July is small and glassy, 6ft from the south-southeast, but short period (7 seconds) and weak energy (792). A clean but weak day.

Saturday 25 July sees 5-6ft from the southwest, 12 seconds, with clean cross-off winds. Energy is moderate (952-1073). Good for a fun session.

Sunday 26 July brings 7-8ft from the southwest, 14-15 seconds, with clean winds. Energy is strong (1963-2257). This is a solid, quality day for experienced surfers.

Monday 27 July is onshore and messy—avoid.

Tuesday 28 July sees 8ft from the south-southwest, 15 seconds, with moderate cross-off winds. Energy is strong (2943-3164). Good for experts.

Wednesday 29 July finishes with 7ft from the southwest, 13 seconds, glassy in the morning. Clean and high quality (1547).

So, the absolute best on offer are Thursday 16 July morning, Tuesday 21 July morning, and Wednesday 22 July morning. Mark those dates for big, clean, powerful reef waves. The rest is a mix of fun and so-so, but those three are the standouts.

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.
