The Lowdown
Alright, this is Rusty, and I’m lookin’ at the waves for Magna Tubes. It’s a reef break that’s fairly consistent, but don’t be fooled—this one’s for the advanced crew only. The water is a freezing 56°F right now, which is a massive 10°F colder than usual for this time of year. That’s seriously unusual, so you’ll be needing a thick suit and a good attitude.
The pattern starts off with a bit of a wait. The first real look is Monday the 24th in the afternoon, with a small 4ft swell from the SSW, but it’s cross-shore and a bit weak. The combined energy is only 887, so it’s not got much punch. The water’s cold, and the vibe is marginal. Tuesday the 25th morning is the first true standout. You’ve got a clean 8ft SW swell with a 13-second period, and the wind is off-shore from the WSW. That’s light and clean, making for excellent conditions for experienced surfers. The energy jumps to 3463, so there’s some real power there. Tuesday afternoon gets a bit bigger at 10ft, but the wind turns cross-shore, so it loses some of that magic.
Wednesday the 26th is a write-off—on-shore winds and poor conditions, same for Thursday. Friday the 28th is small and not worth the paddle. Saturday the 29th sees a bit of a clean-up in the afternoon with a 4ft E swell and cross-offshore wind, but it’s tiny. Then there’s a dry spell of small, weak surf until the 2nd of September.
Now, the real beast shows up on Wednesday the 2nd of September. Morning and afternoon both have a solid 12ft SW swell, period at 13 seconds, and clean cross-offshore winds. The energy is huge—4642 in the morning, 3836 in the afternoon. This is for experts only, and it’s a proper groundswell. That long period means it’ll be better at the reef, with long, clean lines. This is the best on offer, no question.
After that, the 3rd and 4th of September get absolutely massive, with 16ft to 20ft swells, but the wind is messy and cross-shore, turning on-shore. The energy is off the charts, over 8500, but it’s blown out and dangerous. That’s kite-surfing territory, not for paddling. The rest of the outlook fades out with smaller, on-shore slop.
So, the standout is clear: Wednesday the 2nd of September at Magna Tubes. Get on it if you’re advanced, but be ready for a serious session.
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.
