The Lowdown
Alright, Rusty here. Let’s have a look at what’s coming up at Magna Tubes.
The next week and a half is a bit of a mixed bag, but there are a couple of absolute gems hiding in there if you time it right. The water’s sitting at 61°, which is a solid 5° colder than usual for this time of year – that’s a big deal, so you’ll want a thick suit and some booties if you’re heading out. The combined swell energy is going to be pumping at times, hitting some serious numbers.
First up, we’ve got a rough start. Monday the 7th is a write-off with onshore wind and messy, choppy conditions. Forget it.
Tuesday the 8th morning is where it gets interesting. The wind drops to glassy – dead calm, flat ocean – and we’ve got a 4 ft SW swell at 13 seconds. Combined energy is 1122 (moderate), but those clean, glassy conditions will make it look way better than the number suggests. This is a solid window for experienced surfers. The afternoon gets a bit onshore again, so hit the dawn session.
Wednesday the 9th morning is clean with a light offshore wind from the WNW, but the swell drops right off to 2 ft at 15 seconds – that’s a long period, but not enough height to do much on a reef. Combined energy is only 480 (weak). A bit of a lull.
Thursday the 10th morning has some clean 4 ft SW swell at 13 seconds, but the wind is cross-offshore, so it’ll be workable. The afternoon jumps up to 6 ft at a very long 16 seconds, and combined energy climbs to 1694 (strong). That’s proper groundswell, but it’s a cross-shore wind, so expect some chop. Still, for a reef like Magna Tubes, that long period will produce some nice lines.
Friday the 11th and Saturday the 12th are blown out – onshore winds and lumpy, choppy surf. Not worth the paddle.
Now, the standout. Sunday the 13th is a beauty. Morning has a 7 ft SW swell at 15 seconds, with a light cross-offshore wind and combined energy at 2576 (strong). The afternoon gets even better – 6 ft SW at 14 seconds, but with a clean offshore wind from the WNW. Combined energy is 2003 (strong). This is excellent surf for experienced surfers. Clean, powerful, and lined up on the reef. Crowds are possible here, so get there early.
The following week gets a bit messy again. Monday the 14th through Tuesday the 15th are clean but the swell drops. Wednesday the 16th sees a big pulse – 12 ft to 13 ft SW swell at 14 seconds, with combined energy hitting 5774 to 6284 (very strong). That’s big, powerful, and only for experts. The wind is cross-offshore, so it’ll be clean, but those are serious waves. The rest of the week into the 22nd is mostly blown out, too big, or too small to bother with.
So, the pick of the run is Sunday the 13th. That’s your day. Clean, powerful, and proper. Tuesday the 8th morning is a solid second option if you want a glassy session with smaller waves.
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.
