The Lowdown

Alright folks, Rusty here. Let’s take a look at what’s on the table for the next couple of weeks.

We’ve got one spot on the radar, Magna Tubes, and it’s going to be a bit of a rollercoaster. The early part of the period is where the real magic is, so we’ll focus on that.

The action kicks off Sunday the 30th of August, but it’s a bit of a warm-up. Sunday morning sees a 7ft swell from the SW with a solid 10-second period, but it’s a cross-off wind and the energy is just moderate (972). It’s a bit marginal. The afternoon clean up a touch with a 7ft SW swell, but still not the standout.

Now, Monday the 31st of August is where it gets interesting. The morning session is the pick of the entire forecast. We’re looking at a clean 6ft SW swell, but the real story is the period – 12 seconds, a proper groundswell. The wind is glassy, dead calm, and the water is about average for the time of year. The energy is pumping at a solid 1002. This is going to be a ripper, especially for the experienced crew. Magna Tubes is a reef break, so that long-period SW groundswell will be a treat. Just be aware it’s an advanced wave, and it’s exposed to the SE, so that SW swell is right in the slot. Crowds are likely, so get there early.

Tuesday the 1st of September keeps the quality up. The morning is clean with a 8ft SW swell, 12-second period, and light cross-off wind. The energy is strong (1465). This is another excellent session. The afternoon bumps up to 8ft with a 13-second period, but the wind picks up to a moderate breeze, still cross-off, so it’s clean but with more push.

The swell peaks on Wednesday the 2nd of September with a 10ft SW swell, but the wind swings onshore in the morning, making it a bit of a washout. The energy is very strong (3769), but unless you’re a expert, this is a pass. The afternoon gets a full onshore wind, making it a no-go.

Thursday the 3rd of September is a write-off. We’ve got an 12ft S swell with a short, gutless 8-second period, and a 25 mph cross-off wind that’s going to make it a messy, blown-out mess. The energy is strong (2451), but the quality is zero. The afternoon is even worse with a near gale.

After that, there’s a long, ugly gap. From Friday the 4th of September right through to Saturday the 12th of September, the wind is a constant problem. It’s mostly onshore or cross-onshore, the swell drops and gets messy, and the scores are all zeros. It’s a stretch of about 8 days with nothing worth paddling for. The setup is looking more interesting for kite surfing than paddle surfing during that stretch.

Then, on Sunday the 6th of September, it’s like someone flicked a switch. The morning is glassy again with a 8ft SSW swell, 14-second period, and the energy is very strong (2403). This is excellent, but it’s a week out, so take it as a promising call. The afternoon stays clean with a 7ft SW swell.

The rest of the second week shows a few more pulses, but they’re all wind-affected or too small, with the energy dropping back to moderate levels. The best of the late run is an 8ft SW swell on the 13th of September, but it’s hammered by a 28 mph cross-off wind, so it’s not a goer.

So, the bottom line: the first two days, Monday the 31st of August and Tuesday the 1st of September, are your true standouts. Get on them. After that, be prepared for a long wait until the next glassy window on the 6th of September.

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.
