The Lowdown
Alright, Rusty here. Let's talk about what’s coming up at Magna Tubes.
First up, we’ve got a bit of a wait on our hands. Nothing doing until Friday the 14th. The early window on Thursday the 13th is a write-off – there’s some swell, but the wind is messing things up and conditions are poor. So, we sit tight.
Friday the 14th morning is where things start to get interesting. The swell is a clean 5ft from the SW, with a long 15-second period (groundswell), and a light cross-offshore breeze. The wave energy is moderate, and for experienced surfers, this is looking excellent. This is a reef setup, so that long period will draw in nicely.
Saturday the 15th morning is a glassy dream – zero wind. The swell drops a bit to 4ft from the SW, but with that kind of surface, it’s going to be picture-perfect.
Sunday the 16th is a drop-off. Small, short-period chop in the morning, not worth the paddle.
Now, here’s the standout of the first week: Monday the 17th morning. We’ve got a solid 7ft SW swell, a long 14-second period, and clean conditions with light cross-offshore wind. This is for the experienced crew – at 7ft on the reef, beginners will be in over their heads. The crowd here can be a factor sometimes, so get in early.
The middle of the week sees a dip, but things rebuild into the 19th and 20th. Thursday the 20th morning delivers another good 7ft SW swell with light winds.
But the real highlight of the whole outlook lands on Saturday the 22nd morning. This is the one. A pumping 10ft SW swell, a long 14-second period, and light offshore breeze. The wave energy is very strong. This is a serious, expert-only session. The wave direction (SW) is a perfect match for the optimum. Crowds will be there, but for a wave like this, you deal with it.
The last week continues with good pulses. There’s a promising window on Sunday the 23rd morning with 7ft and light winds, and then the final standout of the outlook is on Friday the 28th morning, another 10ft SW groundswell with clean cross-offshore winds. It’s a long-range call, but it looks like a proper way to finish the run.
Overall, expect some multi-day swells, a few flat days in between, and two or three truly epic windows for the big-wave crew. Keep an eye on the wind shifts.
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.
