The Lowdown
Alright, this is Rusty. Let’s talk about what’s happening at Magna Tubes.
Look, I’m not gonna sugarcoat it – the first few days are a write-off. We’ve got a solid swell building, but the wind is just horrible. Saturday the 5th and Sunday the 6th are onshore slop with a strong, raw energy in the water (685 and then a massive 4527). The water is much colder than normal for this time of year, sitting at 62°, so you’ll want a good hood. It’s just not worth paddling out.
Monday the 7th is still messy with a cross-onshore breeze, and the swell is all over the place. Too much size and no shape. Things start to get interesting on Tuesday morning, the 8th. That’s your first real window. The wind goes glassy, just a whisper of air from the NNE, and the swell drops to a clean 4ft from the SW with a nice 13-second period. The energy is moderate (1120), but it’s clean and that’s the name of the game. This is a window for the experienced crew – the reef is exposed and that swell direction is a solid SE match.
The rest of that week is a tease. A few clean mornings with lighter winds, but the swell is inconsistent. Wednesday the 9th is small and clean, but you’re scratching for waves. Thursday the 10th has a bit more size by the afternoon (8ft from the SW, 16-second period) but it’s got a cross-shore chop. Crowds are possible here, and it’s a fairly consistent spot, so there will be bodies.
Then we hit another rough patch. From Friday the 11th through to the 14th, it’s a mess of rain and strong onshore winds. The swell is big and powerful, but it’s a washing machine. Look, if you want to kite, that’s your window, but for a surfboard, forget it.
The real standout, the one that’s got my heart racing, is the afternoon of Wednesday the 16th of September. Mark it. We’re looking at a 15ft swell from the SW with a 14-second period, and the wind is a clean offshore breeze from the WSW. The energy is a staggering 13358 – that’s a serious amount of power. The note says "marginal forecast" but the score suggests otherwise. This is a big, clean, powerful groundswell at a reef that loves that direction. This is for experts only. It’s over 8ft, so it’s a serious step up, but if you’ve got the nerve, this is the session of the forecast.
The following week sees more of that big, sloppy energy and wind. The 20th of September has a clean, strong offshore wind, but the swell is dropping back to 5ft. It’s a clean finish, but not the highlight.
So, to sum it up: Tuesday the 8th morning for a clean, smaller session if you’re good. The absolute standout, the one that might be a legend session, is the afternoon of Wednesday the 16th. That’s the one to plan around.
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.
