The Lowdown
Alright folks, Rusty here. Let's have a look at what's coming our way.
Straight up, the first few days are a write-off. Sunday the 6th and Monday the 7th are a total mess – big, raw swell but with shithouse wind and poor conditions. You don't want to be out there. We’ve got to wait until Tuesday the 8th before things get interesting.
The standout window is Tuesday morning, the 8th of September. Magna Tubes (reef) is looking like the pick of the whole forecast. The combined energy is massive at 1122 (moderate wave energy), with a solid 4ft groundswell rolling in from the SW with a 13-second period. But the real magic is that morning glass – a 5 km/h wind from the north, making it perfectly clean. This is a serious setup for experienced surfers. The water temperature is 62°, which is 4° colder than usual, so it’s noticeably chilly for this time of year. You'll want a decent suit.
After that, we get a lull. Wednesday the 9th is tiny, and Thursday the 10th gets a bit of size back, but the wind is messy. Friday the 11th and Saturday the 12th are back to poor conditions again. It’s a real stop-start run.
We have another promising spell kicking off on Tuesday the 15th of September. Tuesday morning has a clean 5ft SW swell with a 5 km/h offshore wind, excellent for experienced surfers. The afternoon turns it up a notch, with a solid 8ft SW groundswell and clean conditions, making for a great session. The combined energy is strong at 2398 (strong wave energy).
Into the third week, things get a bit more uncertain, but there are a few spots worth watching. On Wednesday the 16th of September, the swell is pushing 8ft SW with a very long 16-second period, combined energy of 3341 (strong wave energy). The wind is cross-shore, so the quality is marginal, but it’s a set-up for a powerful reef break. Unless you’re an expert, this one is for watching.
Friday the 18th of September is the only call in the latter part of the 16-day stretch. The morning has a 6ft SW swell with a 25 km/h offshore wind, which is clean and rideable, but the energy is a bit lower at 1435 (moderate wave energy). The weekend after that is all blown-out and messy again.
So, bottom line: Tuesday the 8th is the absolute best bet – clean, solid, and glassy. Tuesday the 15th is your next best call. The rest is a gamble with a lot of wind and chop.
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.
