The Lowdown
Alright, Rusty here. Let’s have a look at what’s cooking for Magna Tubes over the next couple of weeks.
The forecast kicks off Friday the 11th, but honestly, it’s a bit of a rough start. We’ve got a solid SW swell pushing 6 ft, but the wind is all wrong – cross-on and onshore – making for a messy, choppy surface. The energy is moderate but feels heavy. Friday afternoon is worse, so give it a miss.
Saturday the 12th brings a serious turnaround. The morning session is the clear standout for the first week. The swell drops to 3 ft, but it’s a clean SW groundswell with a long 14-second period, and the wind goes glassy. This is pure, clean, and lined up for the advanced crew at Magna Tubes. The water temp is about average for this time of year, nothing unusual. Get on it.
Saturday afternoon sees the swell jump back to 6 ft, but the wind turns onshore and ruins it. Sunday the 13th is a write-off – strong onshore winds, lumpy conditions, and an 12 ft east swell with short 9-second period. The quality is poor. This is more of a kite-surfing setup than anything else – the beach and reef will be a washing machine.
Monday the 14th is still average, with cross-on winds and an 8 ft east swell. By Monday afternoon, the wind shifts cross-off from the WSW, cleaning it up a bit, but it’s still marginal.
Tuesday the 15th is a solid call. The morning has a 5 ft east swell with clean, cross-off wind from the west. Light breeze, clean lines. This is excellent for experienced surfers – a proper session.
Wednesday the 16th gets a bit wild. The morning shows a 10 ft SW swell, but with fresh cross-shore wind that makes it lumpy. This is big and powerful – only for experts, and even then, it’s a challenge. Wednesday afternoon drops to 6 ft but stays choppy.
The rest of the first week is mixed. Thursday the 17th is marginal but rideable, with 6 ft swell and light cross-on wind. Friday the 18th is poor – onshore wind and choppy.
Now, looking into the second week. Saturday the 19th is a standout. The morning has a clean 6 ft SW swell with glassy wind – excellent conditions for experienced surfers. This is the best of the week. By the afternoon, the swell drops and goes cross-shore, but the morning is a winner.
Sunday the 20th brings another big pulse: a 10 ft SSW swell with clean cross-off wind and a very long 16-second period. That’s strong and powerful. This is for experts only, and the long period will make it fast and hollow at the reef. Get ready.
Monday the 21st and Tuesday the 22nd are poor – onshore wind, big swell, and rough conditions. Tuesday has gale-force cross-off wind, so it’s not surfable.
Wednesday the 23rd and Thursday the 24th see the swell drop off. Thursday morning looks good: 4 ft SW swell with clean cross-off wind and a long 13-second period. Excellent for experienced surfers.
The last few days are building again. Friday the 25th has an 8 ft SSW swell with light cross-on wind – marginal but has potential. Saturday the 26th morning is the real gem in the final stretch: 5 ft SSW swell with glassy, calm wind. Clean, lined-up, and excellent for experienced surfers.
Best on offer: Saturday 12th morning for the glassy, clean 3 ft swell, and Saturday 19th morning for the glassy 6 ft swell. For the big-wave crew, Sunday 20th morning at 10 ft with clean wind is a must.
Expect a few days of nothing in between, but the quality windows are clear. Stay keen.

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.
