The Lowdown

Alright, let’s get into it. This is Rusty, your local surf report.

First up, we’ve got Magna Tubes. It’s a reef break, and it’s strictly for the advanced crew. The water is sitting at 59°, which is a whopping 7° colder than normal for this time of year. That’s a serious chill, so you’ll want a thick suit or a hood. The good news is reef breaks can handle a bit of a cold snap. The wind is a cross-offshore from the WSW at 12 mph, so it’s clean. The swell is a solid 8 ft from the SW with a period of 10 seconds, producing a combined wave energy of 1051. That’s a moderate energy, but the forecast is calling it marginal, so it’s just okay. Not the best start.

Sunday afternoon is a bit smaller, 7 ft, still cross-off, clean, but not a standout.

Monday morning, August 31st, is looking better. Clear skies, a cross-shore wind from the SSW at only 3 mph, and a 6 ft SW swell with a 12-second period. That 12-second period is a groundswell, and it’s got some juice. The combined energy is 1091. Conditions are light cross-shore with small ripples, so it’s a really good time to be out there. This is a solid window for a surfer.

Monday afternoon drops off fast. The swell goes to 2 ft and the wind turns cross-on. Not worth it.

Now, Tuesday morning, September 1st, is a repeat of Monday morning but with a bigger swell. 8 ft from the SW, 12-second period, light cross-shore wind. The energy is 1463. The conditions are clean. This is a strong option.

But the absolute standout of the whole period is Tuesday afternoon, September 1st. The swell bumps up to 8 ft from the SW, with a 13-second period, and a cross-offshore wind from the SW at 9 mph. The combined energy jumps to 2136. This is “excellent surf conditions for experienced surfers,” and it’s clean. That’s your best session. Get on it.

Wednesday morning, September 2nd, the swell gets bigger at 12 ft, but the wind shifts to a cross-on from the ENE at 9 mph. It’s a bit choppy and the energy is 4064, which is strong. It’s marginal, so it’s not as good as Tuesday.

Wednesday afternoon is a write-off. Onshore wind at 19 mph from the E. Poor.

Thursday, September 3rd, has some clean windows with cross-off winds, but the swell is dropping and the wind is strong (22-25 mph). It’s marginal, not great for paddling.

Friday, September 4th, is a total mess. Rain, strong onshore winds from the SSE, and a huge 16 ft swell. That’s over 8 ft, so it’s experts only, and the wind is ruining it. The energy is 6094, but it’s messy. This is more of a kite-surfing show than a paddle session.

The second week gets a bit more complicated. Saturday, September 5th, has a cross-shore wind and a 7 ft ESE swell, but it’s only 10 seconds. Marginal.

Sunday, September 6th, features a 10 ft SSW swell with a very long 16-second period. The energy is sky-high at 4678. However, the wind is onshore from the E. That long-period groundswell is going to want to break straight at a beach break, but at a reef like Magna Tubes, it’s a different story. The onshore wind is the problem. It’s a promising look, but the wind has to improve.

The rest of the week through to September 13th is mostly poor or marginal. Onshore winds, chop, and rain. There’s a big gap of poor conditions.

Then, on Monday, September 14th, we get another true standout. The morning session is glassy. Zero wind from the NNE. An 12 ft swell from the E with a 9-second period. The energy is 3222, which is strong. It’s “excellent surf conditions for experienced surfers.” This is a reef break, so that 12 ft is going to be a challenge, but the glassy conditions will make it a spectacle. The afternoon is also clean with a cross-off, but the morning glass is the real prize.

So, to sum it up: your best bets are Tuesday morning and especially Tuesday afternoon, September 1st, for the best quality. Then, keep an eye on Monday, September 14th, for another glassy, big-wave session. The crowds are listed as “sometimes” at Magna Tubes, so you might find a few out there, but it’s a reef, so it’s not a circus.

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.
