The Lowdown
Alright, let's get down to it. The next couple of weeks at Magna Tubes are a proper rollercoaster. We've got a full 16-day forecast to look at, and it ain't all pretty. The water is running at about 59 degrees, which is a solid 7 degrees colder than normal for this time of year. That's a serious cold snap, so make sure you're suited up properly. It's a big deal.
The first couple of days are all about getting your eye in. Wednesday brings a small, clean 3-foot SSW swell, but the energy is weak, so it's not doing much. The afternoon picks up a little to around 6 feet from the SW, but the cross-shore breeze is going to make it a bit lumpy. It's surfable, but you'll be working for it.
Thursday is when things start to wake up. The swell jumps to a solid 11 feet from the SW, with a strong energy reading. The wind is cross-offshore and clean, which is a huge bonus for this reef. This is big, powerful surf, strictly for the advanced crew. This is the first real standout of the window.
Friday morning is the pick of the first week, no question. The swell is still a hefty 10 feet, but the wind goes completely glassy. Dead flat calm. This is the kind of morning that makes all the flat spells worth it. Clean, powerful, and lined up. The afternoon, the wind swings onshore and it turns to junk, so get your fill early.
Saturday holds decent size, around 8 feet, with clean cross-off winds, but the energy is starting to drop. Sunday brings the biggest swell of the period, hitting a powerful 13 feet from the SW with a massive energy reading. But it's a tease. The morning wind is light and cross-off, keeping it clean, but the afternoon is a complete disaster. The wind howls onshore at nearly 30 mph, making it a total mess. That big swell is there, but you'll need to be out at sparrow's fart to get it.
The middle of the week, from Monday through Wednesday, is a full-on write-off. The wind is onshore, strong, and just plain mean. The swell is still out there, but with that wind, it's going to be a choppy, blown-out sea. This setup looks way more fun for a kite surfer than a surfer, to be honest. We're looking at a solid 3 to 4 day gap with no real surfing to be had.
Thursday the 13th is the next true standout. The wind is light and offshore, the sky is clear, and we've got another solid 10-foot swell on the way. It's a long-range call, so it's promising, but I'd keep my fingers crossed. The days after that see the size ease off, but the winds stay clean and light. There are waves to be had, but nothing that's going to have you calling in sick.
The second week is a bit of a crapshoot. The swells are smaller, less consistent, and the energy is down. There's a modest SW pulse on Sunday the 16th with clean morning winds, and another on Tuesday the 19th, but the power just isn't there. The last day shows a jump in size to 7 feet, but the wind is screaming at 35 mph, which means it's a complete no-go.
So, to wrap it up. If you're planning your week, Friday morning the 7th, with its glassy conditions and solid 10-foot SW swell, is your clear winner. Keep Thursday the 13th as your backup plan, with its offshore winds and another 10-foot pulse. Everything else is either too small, too windy, or just plain ordinary. Get out there and get some.

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.
