The Lowdown
Alright, folks, Rusty here. Let’s take a look at what’s comin’ down the line for Magna Tubes.
It’s a bit of a slow start, I won’t lie. The first couple of days are just there to get the stoke going, but nothin’ to write home about just yet. The real action starts to build from Sunday the 23rd, and we’ve got a solid block of swell rollin’ in.
The standout session is looking like early Tuesday morning, the 25th. We’ve got a solid 10ft groundswell from the SW, with a long period of 14 seconds. The wind is glassy, and the combined energy is cranking (3153). This is a real clean, powerful setup for advanced surfers only. With that kind of size, don’t even think about bringin’ the soft-top. It’s gonna be a proper session.
The water’s a bit of a story here too. At Magna Tubes, it’s running at 56°F, which is a whopping 10°F colder than the long-term average for this time of year. That’s not just a little chilly, that’s a full-on cryogenic situation. You’ll want a thick hood and booties.
Now, lookin' a bit further out, there’s a real bombshell on the horizon. Friday the 4th of September, the afternoon session is lookin' absolutely massive. The forecast is showing an 18ft SW groundswell with a 13-second period, and the combined energy is off the charts at 10990. The wind is clean, cross-off. This is an exceptional, expert-only situation. If you’re not an absolute charger, stay on the beach and watch the pros. The Saturday morning after that is still pumping at 15ft, but it’s likely to be a bit of a hangover from the day before.
The rest of the second week has some solid to big swell, but the wind is all over the place. We’ve got some cross-off and offshore windows, especially on the 6th of September, so there’s plenty to keep an eye on, but the true standouts are definitely that Tuesday the 25th and that Friday the 4th.
Stay warm, get out there, and don’t be a hero in the big stuff if you’re not ready. 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.
