The Lowdown
Alright, surfers, Rusty here. Let’s talk about what’s on the cards for Magna Tubes over the next couple of weeks. This is a reef break that needs a bit of SW groundswell and clean conditions to really show its teeth, and we've got a journey ahead of us.
Right off the bat, the water’s running a bit chilly, about 64°F, which is a touch colder than normal for this time of year. You’ll want that hood or a good thick top.
The first few days are a write-off. Friday the 31st and Saturday the 1st are blown out with fresh cross-onshore winds and lumpy, messy surf. We’re talking about a couple of metres of junk. Sunday the 2nd is still pretty poor, though by the afternoon the wind eases, but the conditions are still questionable.
There’s some hope on Monday and Tuesday, but it’s still marginal. The swell eases a touch, but we’re getting light winds. It’s not until Tuesday the 4th that things start to clean up. That morning, a light offshore wind and a clean 5ft SW swell with a good 12-second period arrives. It’s a start, but not the main event.
Now, hold on to your boards, because Wednesday the 5th is where it gets interesting. The morning is small, but that afternoon, a solid 8ft SW swell with a 14-second period rolls in, and it’s clean. The energy is pumping. That’s a taste of what’s coming.
Then, Thursday the 6th. This is the big one, a real standout. We’ve got a serious pulse of SW groundswell, with the morning seeing a massive 18ft of swell at 13 seconds from the SW. The energy reading is massive, so it’s firing. The wind is fresh but cross-offshore, keeping the faces clean. This is expert territory, no doubt. It's a raw, powerful day. The afternoon backs off a bit to 15ft, but it’s still on.
Friday the 7th and Saturday the 8th are still in the zone, with 10ft of SW swell. Saturday morning is absolute gold – glassy conditions, no wind, and clean 10ft waves. That’s a day for the connoisseur. The afternoon gets chopped by an onshore breeze, so get out early.
We’ve got another run of solid surf from Sunday the 9th through to Wednesday the 13th. It’s consistently in the 10ft to 13ft range, with SW swell and good periods. However, the winds are a bit more mixed during this stretch. There’s a standout window on the morning of Wednesday the 12th if you don't mind a bit of cross-shore wind, with 12ft SW swell at a very long 15-second period. That's a lot of water moving. Keep in mind, this longer period stuff can be a bit tricky on a reef, wanting to stand up and throw, so it’s not for the faint-hearted.
The energy finally winds down after that. By the 14th and 15th, we’re back to smaller surf. The morning of the 15th has clean, tiny 2ft waves, but then, in a strange twist, the afternoon kicks up to a stormy looking 10ft. That one is a bit erratic and poorly organized.
So, if you look at the whole picture, there are two real standouts. The first is Thursday the 6th – that’s a monster day for experts only, a real show of force. The other highlight is the glassy Saturday morning on the 8th – still big, but clean and a bit more user-friendly for the experienced surfer. The long-range stuff after that is promising but not quite as certain, so don’t book your flights just yet.
For the kook crew, keep well away from these waves when it's over 6 feet, this reef isn't a place to learn. When it’s big and windy like that, it might be a better day to watch the kitesurfers.
Stay safe, keep your wits about you, and I'll see you out there.
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.
