The Lowdown
Alright, mates, Rusty here. Let’s get straight into it for Magna Tubes. This is a heavy, expert-only reef setup, so we’re not messing around with beginners here. The long-range picture has a couple of windows that will get the heart pumping, but we’ve got to wade through some junk first.
The first real opportunity kicks off on the morning of Thursday, September 3rd. We’ve got a solid 8ft of SW swell rolling in with a 13-second period, and the wind is dead glassy out of the WSW. That’s prime Magna Tubes. Conditions will be clean and powerful, with the combined energy of all swells directed here registering a strong 1821. This is the best-looking window in the near term, and by a long shot. It’s a standout – but it’s for experienced surfers only. That swell size and the reef break demands respect.
After that morning, things get sloppy quickly. The afternoon sees the wind swing onshore and it all just shuts down. From Friday the 4th through the weekend, we’re looking at a real dry spell. Wind is blowing onshore and cross-on, the swell gets messy, and periods drop short. It’s just a poor run of surf. Don't even bother looking at your board; it’s a complete waste of time.
There is a chance of something on the morning of Monday the 7th. The wind turns light and variable, with a 6ft SW groundswell at a long 14-second period. It's rated as marginal, though – probably a tide issue. The energy is there (3706 on the combined scale), but the quality might not fully line up. It’s worth a look, but I’d keep expectations low.
The following days are mostly a write-off. Swell drops, wind stays messy, and periods get short. There’s a fleeting bit of clean surf on the afternoon of Wednesday the 9th, but it's tiny, barely 3ft. Not really worth paddling out for.
Here’s the thing, though – the real standout on the horizon is the morning of Saturday, September 12th. This is a week and a half out, so treat it as promising but less certain. But if it comes together, look out. We’re talking a solid 10ft of SSW groundswell at a long 14-second period, with clean, cross-off winds from the SW. The combined wave energy is a massive 3856. That’s a fully firing Magna Tubes. It's going to be big, powerful, and perfect for those who know what they're doing. Mark that date in your brain. This is the day the whole window is building toward.
After that, the swell backs off into the second week, but the winds stay a bit more favourable. The mornings of Monday the 14th and Wednesday the 16th have clean, cross-off conditions, but the size is down in the 4ft to 6ft range – fun, but nothing that’ll get you too excited.
So, bottom line: if you’re an expert, tomorrow morning (Thursday the 3rd) is your best near-term bet. But the one to truly plan around is that Saturday the 12th. It could be a day you remember. Keep an eye on the forecast, because long-range calls can change, but that one has real potential. This is Rusty, signing off.

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.
