The Lowdown

Alright, Rusty here, let's have a look at what's coming down the pipe.

Right off the bat, the next week and a half is a bit of a write-off. We've got swell, sure, but the wind is just plain ugly – mostly onshore and cross-onshore from the east and southeast. That's going to chop everything up into a mess. Thursday the 3rd kicks off with a 8ft SSW swell, but it's got a 12 mph wind ruining it. That just sets the tone. Friday and Saturday aren't any better either. Sunday the 6th actually has a massive 6ft SSW swell with a wild 21-second period, but the 22 mph cross-onshore wind will turn it into a washing machine. We're looking at combined wave energy values of (2045), (1333), (1785) and so on, but it's all for nothing without a clean window.

There's a small glimmer on Monday the 7th morning. The wind drops right off to a light 6 mph breeze, and while it's cross-onshore, the 7ft SSW swell with a 14-second period has some proper energy behind it (4050). It's still only marginal, but it'll be the cleanest thing we've seen. Tuesday the 8th is similar, smaller though. Then Wednesday the 9th, the wind actually swings offshore from the southwest. The swell is small, 3ft to 4ft, but that 14-second period from the SW is clean. It's a small window of decent, clean shape for the patient surfer.

Now, here’s where it gets interesting. The real standout is Monday the 14th of September. Monday morning, we get a clean 13ft easterly swell hitting Magna Tubes. The wind is light and offshore from the north – you can't ask for much better than that. The combined wave energy is a solid (4145). This is for experienced surfers only at that size, but the conditions are described as excellent. That's the one to circle on the calendar. It’ll be a heavy, powerful reef break with those clean conditions.

Following that, Tuesday the 15th is also worth a look. It drops to a more manageable 6ft to 5ft from the east, with a clean offshore wind from the west-southwest, especially in the afternoon. That's a much friendlier size for the drop-in crowd. Then on Wednesday the 16th, things get interesting in a different way. The morning is dead calm – glassy – with a tiny 2ft long-period SW groundswell (17 seconds). It's small, but glassy conditions at a reef break like Magna Tubes can be a real treat for a longboard or a fish. The afternoon picks up a bit to 4ft with a light offshore breeze.

The very end of the run, the 17th and 18th, looks like it's blowing up again with some serious size. Thursday the 17th has a 13ft to 15ft SW swell, but the wind is a strong offshore breeze. That might be too gnarly for most, but for the few who are keen, it'll be a beast.

So, to sum it up: the first week is mostly a bust because of the wind. Your best bets are the small, clean window on the 9th, and then the big, clean standout on the 14th for the experts. The 15th and 16th offer cleaner, more manageable waves for everyone else.

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.
