The Lowdown
Alright folks, Rusty here. Let's get into it for Magna Tubes over the next couple of weeks.
We're looking at a reef break that needs a solid SW groundswell to work. The start of this forecast is firing, but the wind will be the deciding factor. There's a window of pure, clean power early on, and then it gets proper heavy and messy before it cleans back up at the end.
Tuesday the 4th kicks things off clean. A light N breeze with a cross-off wind and 1.4m of SW swell at 12 seconds. The water’s pushing a solid moderate energy (1032). It’s a punchy, lined-up reef wave that's perfect for getting the arms going.
Wednesday morning drops slightly to about 3 feet but the period stretches out to 15 seconds, making for a nice, long groundswell. Clean again. Wednesday afternoon is where the size starts to show. Swell jumps to around 6 feet with a 16-second period. The energy kicks way up (1734). Still clean, but the power is definitely on the rise.
Now, Thursday the 6th. This is the day to be out there. The morning has 12 feet of SW swell, but the wind is a bit light and crosses up, adding some texture. But Thursday afternoon is the absolute standout. You have 10 feet of SW swell, a 13-second period, and a cross-off breeze. The energy is strong at 3354, and the conditions are excellent for experienced surfers. Big, clean, powerful reef. This is the one. If you're advanced, don't miss this window.
The weekend gets ugly. Friday and Saturday still have solid size, 8 to 10 feet, but the wind picks up and gets more cross. It's still rideable for experts, but the quality fades. Sunday the 9th is a write-off. Big swell, fresh winds, heavy rain, and a lumpy ocean. Not good.
Moving into the new week, from Monday the 10th, the swell direction shifts to the SSE and the period shortens. The energy stays massive (5000+), but the onshore wind and choppy conditions make it a mess. The 12th and 13th are completely blown out with poor conditions and fresh cross-onshore winds. This is definitely kite-surfing territory, not for my board.
Things settle down around the 14th and 15th. The swell eases and the direction swings back to the ESE. The morning of the 15th looks promising—clean with a light offshore NW wind and around 7 feet of ESE swell. The energy is still hefty, but it's much cleaner, though the period drops to 10 seconds.
The end of the window on the 17th and 18th brings a return to glassy conditions. Monday morning has a slick, mirror-like ocean with 2.3m of ESE swell. It's a short-period swell at 8 seconds, but it's clean. Tuesday morning is another great one—glassy with 1.5m of SW swell and a 12-second period. Perfect, lined-up waves to finish the run.
Bottom line: Thursday afternoon the 6th is your big swing. That's the winner. And keep an eye on Tuesday the 18th for a clean, fun session. The middle is a war zone.
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.
