The Lowdown
G’day, Rusty here. Look, it’s been a slow start for Magna Tubes — there’s nothing worth paddling out for until Thursday the 28th of August, and even then, it’s touch and go.
Thursday 28th August is where things first start to look a little interesting. Early morning, you’ve got a 5-foot swell from the east, with a period of 10 seconds. But the real story is the wind: glassy conditions. That’s a major positive for this spot, meaning you’ll get clean faces. The water temp is running a very unusual 58°, much colder than normal for this time of year, so a good 5/4 wetsuit is non-negotiable. Combined swell energy is moderate, sitting at (858). Friday 29th sees a drop-off: 4-foot from the east on Saturday morning with a light offshore cross-off breeze from the southwest, keeping it clean, but the energy drops to (569). Not a stand-out.
Monday 1st September is a true highlight. Early morning, you’re looking at an 8-foot southwest groundswell, 11-second period — that’s quality, longer-period energy. Wind is glassy again, so the lineup will be clean. This is excellent for experienced surfers; it’s pushing big enough that less experienced crew are better off sitting it out. Combined swell energy is strong at (1638). The swell direction (SW) is a good match for Magna Tubes’ optimum (SE), so expect well-shaped, powerful waves. This spot is a reef, fairly consistent, and it can draw a crowd sometimes, so expect company. This morning window is the best on offer.
Tuesday 2nd September keeps the pulse going. Wednesday morning has an 11-foot southwest swell, 13-second period, with a cross-off breeze keeping it clean. That’s solid, powerful surf (energy 3924), but it’s getting into the expert-only zone over 8 feet.
The second week sees a messy run. There’s a big swell spike from the 3rd to the 5th of September, but conditions are blown out or just too huge — 23-foot on the 4th with gale-force onshore winds is a no-go. By Sunday 7th September morning, things drop back to a manageable 5-foot southeast swell, period 11 seconds, light cross-off breeze, and clean conditions (energy 1113). It’s a solid option for the second week, but not a stand-out. By Wednesday 10th September, it fizzles out to ankle-high junk with onshore winds.
Overall, lock in the glassy morning of Monday 1st September as the pick of the run. Clean, powerful, and proper. 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.
