The Lowdown
Alright folks, Rusty here. Let’s get straight into the outlook for the next couple of weeks.
We’ve got one spot on the radar, and it’s a specific kind of affair. Magna Tubes is a reef break that only works for advanced surfers, and it’s fairly consistent. Looking at the whole 16-day window, the first couple of days are a bit of a warm-up, but the real magic starts to build as we head into the back half of the first week and beyond.
The first real standout is shaping up for Thursday, July 16. The morning session is the pick of the early period. We’re looking at a solid 10ft swell from the SW, with a period of 14 seconds – that’s a proper groundswell with some serious energy behind it, and the combined energy reading is a hefty 3236. The wind is offshore from the W, barely a breath at 3 mph, so it’s going to be glassy and clean. This is excellent surf for experienced surfers, but at that size, it’s strictly for the crew who know what they’re doing.
The next big call is for Tuesday, July 21. This is the one that’s got me buzzing. The morning shows an 12ft SW swell with a period of 16 seconds – that’s very long period, which is perfect for a reef like this, giving it shape and power. The combined energy is a massive 6478, and with a light WSW breeze, it’s clean. The afternoon is a bit messier with a cross-shore wind, but the morning window is exceptional for experts. This is a serious stand-out session.
Looking further ahead, Thursday, July 23 afternoon has a clean 13ft SW swell with a 13-second period and a 5438 energy reading, another exceptional one for the experts. Then Saturday, July 25 morning also looks incredible: 12ft SW swell, 15-second period, a staggering 5703 energy, and light offshore winds. Clean and powerful.
There’s a bit of a lull in the middle around the 18th and 19th, with smaller surf and strong winds, but the second week keeps delivering. The standout in that later period is Wednesday, July 29, with a 13ft SW swell, 15-second period, and a combined energy of 7089. That’s a serious amount of power, and the wind is clean. This is a promising, long-range event that could be the best of the entire run.
Water temperature is about average for the time of year, nothing unusual to report on that front.
So, to wrap it up: if you’re an advanced surfer and you know Magna Tubes, the real highlights are the morning of Thursday July 16, Tuesday July 21, and the one that’s a bit further out but looks huge, Wednesday July 29. Get on it.
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.
