The Lowdown
Alright, Rusty here. Let’s talk about what’s coming up for Magna Tubes.
We’ve got a real mixed bag on the horizon. The water is sitting at 63°, which is a bit colder than normal for this time of year – a good 3° off the mark, so you’ll want a decent suit.
The first real glimmer of something good doesn’t hit until the morning of Monday the 5th of August. We see a 4ft easterly swell with a period of 10 seconds, and a light cross-offshore breeze. The energy is moderate (848), and it’s looking clean. The best of the early action actually shapes up on the morning of Wednesday the 7th of August. That morning we’ve got a solid 8ft swell from the southwest, with a 14-second period – that’s proper groundswell, with moderate-to-strong energy (2869). The wind is a light 6 mph offshore from the WNW, so it’s going to be clean. This is a standout for the first week, but remember, at 8ft, this is only for experienced surfers.
The real standout, though, the one to circle on the calendar, is the morning of Friday the 14th of August. The wind is glassy – dead calm, 0 mph from the southwest. The swell is a solid 10ft from the southwest, with a 15-second period, driving some very strong energy (4105). That’s as clean as it gets, but it’s big. This is expert-only territory. The following morning, Saturday the 15th of August, is also exceptional for experts, with an 12ft SW swell at 14 seconds and a slight cross-offshore breeze, making it clean (5065 energy). That’s the absolute peak of the run.
The week in between gets a bit messy. From the 9th through the 11th, the wind turns onshore and the conditions get poor. There’s a break in the action, with a few days of rough, choppy surf. Then the 12th of August offers a reprieve with a smaller, cleaner 5ft easterly swell, which is a nice option for the less confident crew.
So, to sum it up: the first week is a slow burn with a few clean windows, but the real prize is the glassy, powerful swell on the 14th and 15th of August. That’s the one you want to be ready for.
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.
