Table - best surf conditions forecast for Magna Tubes over the next 16 days.
The Lowdown
Alright, this is Rusty. Let’s take a look.
It’s been a rough start at Magna Tubes. There's a lot of swell showing up early, but the wind is absolutely killing it for the opening weekend. The combined swell energy is pumping hard at 3930 on Sunday, but a 40 km/h southerly will make it a mess.
The first real standout I see is Thursday morning, the 14th of August. The wind turns light from the north, giving us clean, cross-off conditions. A solid 5ft SW groundswell with a long period of 15 seconds is coming through – that’s proper energy moving with a combined energy of 1142. This will be a session for experienced surfers. The reef will handle that long period well. There will be a few others out, so expect some company.
Another special mention is the weekend on the 22nd and 23rd of August. This is the long-range one to watch. Saturday the 22nd morning has a 7ft SSW swell (12 seconds) with a fresh 1821 of energy and a light NW breeze – clean for the experts. But Sunday the 23rd is the standout: glassy conditions with zero wind and a 6ft to 7ft SSW groundswell at 12 to 14 seconds. The combined energy is around 1765 to 1855, and with the glassy surface, those waves will be peeling perfectly. This is the best on offer for the whole window. Keep an eye on it as we get closer.
We have some smaller windows too. Friday morning the 15th has a small 4ft SW swell but clean wind, and Sunday the 16th through Monday the 17th offers a small 4ft to 5ft easterly windswell. The period is short at 8-9 seconds, and the energy is pretty weak (around 262), so it’s small and crumbling.
The water is absolutely freezing – it’s running 5° colder than normal for this time of year, sitting at just 58°F. Bring the thickest wetsuit you own.
So keep your eyes on Thursday the 14th for solid power, and Sunday the 23rd for the glassy jackpot. The early weekend is a write-off, but the second half of the period has some real hope and some smaller clean windows in between.
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.
