The Lowdown
Alright, folks, Rusty here. Let’s break down Magna Tubes for the next couple of weeks.
Honestly, it’s a tough run. We’re seeing plenty of raw power in the water, with combined swell energy readings hitting the thousands, but the wind is fighting us almost the whole way. The water is a bone-chilling 55°F – that’s 11°F colder than normal for this time of year. You’ll need the thickest suit you’ve got and maybe some booties.
The only real standout is the Friday morning on the 11th. The wind goes completely glassy – dead calm. We’ve got a clean 6ft groundswell from the SW with a long 13-second period and a combined energy of 1274. The report calls it “excellent surf conditions for experienced surfers,” and I couldn’t agree more. That’s a proper reef-cranking session. This one’s for the advanced crew only, as the size is well over the 5ft mark.
The run-up is average. Thursday the 10th is messy with a 3ft to 7ft SW swell but cross-off winds. After Friday morning, the wind turns onshore and it’s all over. Saturday the 12th and Sunday the 13th are poor, with lumpy onshores despite some size.
There’s a second window on Tuesday morning the 15th. We get glass again with a 5ft E swell (11s). The energy is moderate at 930, and the report says “expect very good surf conditions.” It’s a solid second pick, but it’s smaller than the Friday session.
Looking further out, the Sunday the 20th has clean cross-off winds with a 7ft SSW swell and a super-long 18-second period, plus very high energy (3015). That’s a dream combo for a reef break, but it’s over a week away, so treat it as a promising maybe.
The rest of the 16-day window is mostly blown out, with long gaps of poor, onshore conditions from the 16th through the 25th.
Final call: Friday the 11th morning is the one to circle. Tuesday the 15th morning is your backup. Keep an eye on that Sunday the 20th as a potential sleeper. Bring your warmest gear.
This is Rusty, out.

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.
