The Lowdown
Alright, Rusty here again. Let’s talk about Magna Tubes in feet and miles per hour.
Right now, the water is sitting at a nippy 60° Fahrenheit, feeling way colder than normal for this time of year, so you’ll want the thick rubber. We’ve got a quiet start. The first real look is Monday afternoon with a messy 7ft SW swell and onshore wind – not the one.
Tuesday morning, September 8th, that’s the call to paddle out. The wind goes glassy with a light northerly breeze, and we get a clean 4ft SW groundswell. The conditions are prime for experienced surfers. The wave energy is solid but not out of control. It’ll be a clean, makeable morning.
The next few days are a bit all over the place, but Saturday morning the 12th sees the wind go glassy again with a 6ft SW swell. It’s clean and lined up for those who can handle the reef.
Now, the big one. Wednesday afternoon the 16th is the standout. A massive 13ft SW groundswell, period at 16 seconds, with a wild energy reading. The cross-off wind keeps it clean. That’s expert territory, with huge, powerful walls. Not for the casual surfer.
The following Thursday (17th) still has a solid 13ft to 12ft swell with clean cross-off wind, but it’s a tick smaller. Sunday morning the 20th looks great for a smaller session, with 5ft SW swell and glassy, clean conditions.
The last big pulse on the 22nd hits 16ft, but the wind is cranking onshore at 25 mph and it’s choppy – just a mess.
My picks? Tuesday morning the 8th for the clean, glassy lines, and if you’re an expert after a real thrill, Wednesday afternoon the 16th is the one to wait for. Crowds can show up here sometimes, but that big swell will keep it quiet.

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.
