The Lowdown
Alright, surfers, Rusty here. Let’s talk about Magna Tubes. It’s been a rough stretch, and honestly, the start of this outlook is a write-off. We’re looking at several days of nothing but onshore junk and poor conditions. From Thursday the 3rd all the way through Sunday the 6th, it’s all cross-onshore and lumpy, with strong winds and messy surf. Don’t bother paddling out; the setup looks more interesting for kite surfing than paddle surfing.
Things start to look a little more promising on Monday the 7th. We get a morning session with a 7ft SSW swell (combined energy of 3018 – solid moderate to strong), but the wind is a light cross-onshore, so it’s not perfect. The water’s cold, too. For Magna Tubes, the water temp is sitting at 62°, which is 4° colder than normal for this time of year – that’s way more than just a chill, that’s a notable drop.
The real standout, and the one to circle on your calendar, is Tuesday the 8th. We’ve got clean, glassy conditions in the morning. A 4ft SW groundswell with a period of 13 seconds will be peeling nicely. The combined energy is a moderate 1180, and with the glassy surface, this is excellent surf for experienced surfers. This is the best on offer.
Wednesday the 9th and Thursday the 10th drop off again with smaller, marginal surf. Thursday afternoon sees the energy drop right out to just 100.
We then hit another rough patch from Friday the 11th through Sunday the 13th with more onshore and lumpy conditions, some with very strong winds.
The next true highlight comes on Monday the 14th. The afternoon session delivers a 10ft SSW swell (combined energy of 4149 – strong) with light offshore winds from the SW, making for clean conditions. That’s excellent for experienced surfers. Tuesday the 15th is also clean with cross-offshore winds and a 7ft SSW swell, but the wind picks up a bit.
After that, the second week is more of a mixed bag with clean but smaller surf and some periods of onshore wind. The 18th of September looks like a write-off again.
So, the call is simple: wait for the glassy morning of Tuesday the 8th or the cleaner afternoon of Monday the 14th. Those are your windows.
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.
