The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming up for Magna Tubes.

We’ve got a real mixed bag on the cards, starting with a gorgeous Monday morning on the 31st of August. The water is a chilly 59°, a full 7° colder than usual for this time of year, so that’s a proper shock to the system. The payoff is a solid 6ft of swell from the SW, with a long 12-second period pushing through. The combined energy is pumping at 1091 (moderate to strong), and with glassy, 3 mph southerly winds, it’s going to be clean. This is the standout session for the forecast period – an advanced wave for experienced surfers only, and it’s absolutely worth the early alarm.

Tuesday the 1st of September sees the swell bumping up to 8ft in the morning and 8ft in the afternoon, still from the SW with a 12-second period. But the wind swings to a light cross-onshore, which messes with the surface a bit. The energy is huge (2159 in the afternoon), but it’s not as clean as Monday. For the advanced crew, there’s still plenty of power, but it’s not the ‘go’ day.

Wednesday the 2nd of September brings even more size – 10ft from the SW with a 13-second period (3442 combined energy). The morning has a light cross-shore wind, which is workable, but the afternoon gets cross-onshore again. This is big, powerful water. At over 8ft, this is strictly for experts, and the short period between sets from this long-period groundswell might make it a bit roly-poly.

From Thursday the 3rd of September through to the 9th, it’s a write-off. We get rain, onshore winds, and a lot of messy, blown-out conditions. The wind hits 25 mph on the 6th and 7th, with swell hitting 13ft. That’s not surfing; that’s survival. The setup looks more interesting for kite surfing than paddle surfing during that stretch.

After a long, ugly gap, Thursday the 10th of September shapes up as another sneaky good one. The swell drops to 4ft from the E, with a 9-second period, but the winds go glassy again – 3 mph from the WSW and then SSW. The energy is low (209 and 221), but for a small, clean, fun board, it’s a beautiful morning and afternoon. The break is fairly consistent, but crowds are possible here, so get there early.

The real wildcard is Sunday the 13th of September. We get a clean 6ft SW swell (11-second period, 1008 combined energy) with a light cross-offshore north wind. This is another excellent session for experienced surfers, with clean, lined-up waves. It’s a long-range call, so promising but less certain.

Monday the 14th of September holds 7ft to 7ft from the SW with a clean cross-offshore wind in the morning, but the afternoon gets a bit of cross-chop. Still plenty of power there (1160 combined energy).

The 15th of September tries to pump a massive 16ft of S swell, but it’s onshore and messy. A big miss.

So, the pick of the bunch is Monday morning the 31st of August – glassy, powerful, and clean. Thursday the 10th of September is the small-wave glass-out option. Keep an eye on the 13th of September for another clean, powerful window.

Rusty, signing off.

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.
