The Lowdown

Alright, let’s break it down. The standout is Wednesday morning, 19 August, at Magna-Tubes – that’s your session.

The water temp is 13°, which is about 6° colder than average – far colder than usual, so grab a thick wetsuit and boots.

Wednesday morning, 19 August, at Magna-Tubes (reef) is the best of the whole forecast. You’ve got a solid 3.0m swell from the SW with a period of 13 seconds, pumping 2702 units of energy (moderate to strong). The wind is glassy from the SW at just 5 km/h – that’s offshore for this spot. Conditions will be clean and lined up. This is excellent surf, but it’s advanced-level only – the reef and size mean it’s not for beginners. Crowds can show up sometimes.

Wednesday afternoon gets windier – 25 km/h cross-off – still clean but not as glassy. Thursday morning, 20 August, brings a bigger 4.0m SW swell at 14 seconds, with 5729 units of energy (strong to very strong). That’s only for the experts – too big for most. Winds are 15 km/h cross-off, so it’s clean, but the size is huge.

Friday morning, 21 August, drops to 2.4m SW, but onshore wind from the ESE at 10 km/h makes it bumpy. That trend continues into the weekend. Saturday morning, 22 August, has 2.0m SSW with a nasty 40 km/h cross-off – that’s more kite-surfing than paddle surfing, given the beach and reef setup. The energy is still moderate (1338 units), but the wind is brutal.

Sunday, 23 August, through Monday, 24 August, offers marginal conditions – 2.4m to 1.9m SW swells, with light cross or cross-on winds. Tuesday, 25 August, has 2.5m SW on the morning with onshore wind – not good. The rest of the week into early September is mostly marginal or poor, with onshore winds and dropping swell. The last clear standout is Wednesday morning, 26 August, with 2.1m SW at 14 seconds, 1922 units of energy, and light cross wind – still worth a look but not as good as the 19th.

The best of the bunch is Wednesday morning, 19 August. Go get it.

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.
