The Lowdown
Alright, let’s break it down.
First thing, the water is friggin' cold—58°F, which is about 8°F colder than normal for this time of year. You’ll want a thick suit and maybe hood.
The 16-day forecast has some serious juice, but you gotta be patient. Monday the 24th of August kicks off with a 7ft SW groundswell at 12 seconds. The morning is the call—offshore light breeze, clean, and the energy is strong at 1101. For experienced surfers, that’s a solid start.
Tuesday the 25th steps it up. Morning brings 8ft from the SW, 13 seconds, cross-offshore breeze, and energy at 3463. This is proper reef wave territory, not for beginners—over 5ft means it’s getting serious.
Wednesday the 26th is trash. Onshore wind from the East at 18 mph kills it. Skip it.
The end of the week into the weekend is small and weak. Knee-to-waist high with average wind. Not worth it.
Now, the big one: Wednesday the 2nd of September. Morning session has a 15ft SW swell, 11-second period, and a solid offshore wind from the WNW at 21 mph. Clean and pumping. Energy is a massive 5501. That’s big, powerful, and for experts only. Crowds are possible, so go early.
But Thursday the 3rd of September is monstrous. The swell hits 21ft from the SW with a 17-second period—super long period groundswell with extreme energy at 24928. The wind is cross-offshore. The data says it’s too big for the break, and at that size, it’s a survival mission. Only heavy hitters should even consider it. Friday the 4th is similar, 20ft SW at 15 seconds, but the afternoon on Friday the 4th is the true standout. Wind drops to a gentle 9 mph cross-offshore, the swell is still a massive 20ft, and the period holds at 15 seconds. Exceptional conditions for experts only. That Friday afternoon is the best session of the whole run.
After that, the first week of September gets ruined by strong winds and rain, then fades into small, glassy conditions by Tuesday the 8th of September—4ft SW swell, flat calm. A nice little clean-up wave to end the period.
So, the standout: Friday 4th of September afternoon at Magna Tubes. Too big for anyone but the diehards. Second best is Wednesday morning the 2nd of September.

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.
