The Lowdown

Alright, this is Rusty, and I’m lookin’ at the 16-day surf picture for Magna Tubes (Magna-Tubes).

Right off the bat, let’s get real about this spot. It’s an advanced reef break that’s fairly consistent, but the water’s been hammered by a cold snap – 58°F and the anomaly is a brutal -9°F, so it’s gonna feel much colder than normal for this time of year. The optimum swell direction is from the SE, but most of what’s coming is from the SSW and SW, which is a bit off the mark.

The first few days are a write-off. We’ve got a fresh cross-onshore breeze on Wednesday the 12th with a messy 3ft to 10ft lump. Thursday the 13th is a no-go with choppy cross-onshore slop. It ain’t until Friday the 14th that we get a sniff of hope. The morning is looking clean with a cross-offshore breeze from the north, and a 5ft SW swell (period 15 seconds) rolling in. The combined energy is moderate (1331).

Saturday the 15th is where we finally get a standout. The morning is glassy – dead calm wind – with a 4ft SW swell (period 14 seconds). The combined energy is moderate (731). It ain’t huge, but that glassy surface is gonna make it a dream to surf. Expect some crowds here though; it gets busy sometimes.

Then we hit another little gap. Sunday the 16th is just marginal. But Monday the 17th is another standout and the best on offer. Morning is glassy again, with a 5ft SW swell (period 14 seconds) and combined energy is strong (1149). The report says “excellent surf conditions for experienced surfers” – and that’s who this break is for. That 5ft is solid on a reef, and with a 14-second period, the waves will have some real power and shape.

The second week gets a little messy. Tuesday the 18th is still rideable with clean 6ft to 5ft SW swell, but Wednesday the 19th is a poor 2ft with some rain showers. The swell picks up again Thursday the 20th but it’s ruined by a strong cross-onshore wind.

Around Saturday the 22nd of August, we get another pulse of SW groundswell reaching 7ft to 7ft, but conditions are a bit lumpy with cross-onshore and onshore winds. That size is gettin’ into expert-only territory.

The period around Monday the 24th looks promising again – clean with a 5ft SW swell (period 12 seconds) and a light cross-offshore breeze. The combined energy is moderate (794). And finally, on Thursday the 27th of August, we get another clean, cross-offshore morning with a 5ft SW swell (period 13 seconds). That’s a solid way to end the forecast window.

Overall, this place has a few good windows but a lot of waiting. The standout is Monday the 17th – glassy conditions with a strong, 5ft SW groundswell. Saturday the 15th is a close second for the clean glass. Don’t sleep on the cold water, and remember this is a reef break for experienced hands only.

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.
