The Lowdown
Alright, Rusty here. Let’s talk about what’s on offer at Magna Tubes.
This is a reef break that takes a south-east swell direction best, and we’ve got a long window of surf lining up, but it’s a mixed bag. The water is sitting at 60°F, which is a whopping 6°F colder than usual for this time of year – that’s a seriously unusual chill, so don’t skimp on the rubber.
Things kick off on Tuesday the 8th of September with some real promise. Tuesday morning is your standout moment early on: clean, glassy conditions, 4ft of swell from the SW with a 13 second period, and the combined energy is moderate (999). It’s a touch over 5ft, so maybe not for absolute beginners, but clean and lined-up for the more experienced. That morning window is the one to chase. By afternoon, the wind swings onshore and it gets messy, so grab it early.
Wednesday the 9th is smaller with cleaner cross-off winds in the morning, but the swell drops to 2ft – a bit weak for this exposed reef. Thursday the 10th sees a jump in size, especially Thursday afternoon: 7ft from the SW with a very long 16 second period, and the energy bumps up to strong (2081). That’s a proper groundswell, but the wind is cross-off and the surf quality is only marginal. Still, the energy is there. Friday the 11th gets bigger again but the wind goes cross-on and onshore, so it’s a write-off by afternoon.
There’s a quiet patch from Saturday the 12th through Monday the 14th – surf is there but the quality is dodgy due to onshore or tricky winds. Monday afternoon though, glassy conditions return with 4ft of SW swell and good energy (813). That’s a nice sneaky session if you’re keen.
Now, the real standout of the whole outlook is Wednesday the 16th of September morning. We’ve got a solid 10ft SW swell with an 18 second period – that is very long period groundswell. The combined energy is massive (5561), and the wind is cross-shore and clean. That’s expert territory for sure – over 8ft, so leave the beginners on the beach. This is a powerful, pulsing reef set-up.
Then, Thursday the 17th of September morning is a gem: glassy, calm winds, 8ft SW swell with a 15 second period, and excellent conditions for experienced surfers. Energy is strong (3392). Another top pick for the crew that know what they’re doing.
Later in the week, Friday the 18th afternoon brings a solid 10ft SE swell with a moderate 11 second period, and here’s the kicker – clean offshore wind from the WNW at 16 mph. That’s a rare combo for this spot, and it’s excellent for experienced surfers. The swell direction is slightly off the optimum (SE vs the ideal SE), but offshore wind makes up for a lot.
From the 19th through the 20th, the swell stays big (8ft to 10ft) but the period drops to 9-11 seconds, and the wind is cross-off and clean. It’s still big and rippable for the skilled crowd, but the quality is not as pristine as those earlier days.
After that, from Monday the 21st onward, the wind turns onshore and the conditions get pretty ugly all the way through to the 23rd. The swell is still pushing through, but with onshore and cross-onshore winds gusting up to 22 mph, it’s a choppy, lumpy mess. Not worth paddling out unless you’re after a fight.
So, in short: grab Tuesday the 8th morning for a clean start. But the true standout is Wednesday the 16th morning for that huge, long-period groundswell and clean conditions – that’s the one to circle on the calendar. Thursday the 17th morning and Friday the 18th afternoon are also crackers for the experts. The rest is a bit of a slog.
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.
