The Lowdown
G'day, I'm Rusty, and I've got the lowdown on the local surf for the next couple of weeks. The only real spot on the menu is Magna Tubes, a reef break that's all about the SE swell direction. Right now, the water's sitting at a pretty typical temperature for this time of year, so no surprises there.
The next few days are a bit of a write-off, with small, messy swell and questionable conditions. But hold onto your boardies, because things start to fire up from Sunday, August 16th. The first standout is Sunday morning, with a clean 5ft SW swell and a solid offshore breeze. The wave energy is moderate (904), and the conditions are set to be very good. It's a great window for the keen surfer.
Then, Monday August 17th rolls in with a solid 8ft SW swell and a cross-off breeze. The energy is pumping at 2307, and the wave quality is rated excellent for experienced surfers. This is a serious session, but it's for the crew who can handle it. Tuesday August 18th is a repeat performance, with another 7ft SW swell and excellent conditions, so keep that in mind.
The real blockbuster, though, is looking like Saturday, August 22nd. The models are hinting at a massive 16ft SW groundswell, with a very long period of 15 seconds. The energy reading is a staggering 10484, which is next-level. The morning looks clean with a cross-off breeze, but this is strictly for the hardcore crew – it's a big, powerful, and dangerous swell. The wind cranks up to 37 mph in the afternoon, so that window is a no-go.
After that, the swell drops but stays solid through the following week. The wind is a bit of a mixed bag, but there are pockets of clean conditions. Keep an eye on August 27th, Thursday morning, with a 7ft SW swell and a clean offshore wind. It's another one for the experienced surfers.
Overall, the best of the best is the Saturday morning of the 22nd. It's a long-range call, so keep an eye on the charts, but if it comes together, it'll be a day to remember. For the rest of us, Sunday the 16th and Monday the 17th offer the cleanest, most manageable waves.
Stay safe, and I'll see you out there.

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.
