The Lowdown
Alright, Rusty here. Let’s talk about Magna-Tubes.
The first few days are a total mess. Sunday the 9th through Tuesday the 11th is blown out with cross-onshore winds and messy conditions. You wouldn’t bother. That run of poor surf stretches through Thursday the 13th with only a couple of so-so windows.
The first real window is Saturday the 15th morning. You’ve got a clean 7ft swell from the east, a short 8-second period, and a moderate offshore breeze from the northwest. It’s punchy, clean, and for experienced surfers only at that size. Strong energy (1410) but short period means it’ll be a bit sectiony. That’s the best session of the first week.
Sunday the 16th is smaller, around 5-5ft from the east, clean but with very low energy (336). Good for a longboard.
Monday the 17th goes glassy with a 3ft southwest swell and a long 18-second period. It’ll be clean and lined up but small and slow between sets.
The big one is Wednesday the 19th morning. A solid 8ft southwest swell with 11-second period, clean with light cross-offshore wind, and strong energy (1786). That’s excellent for the experienced crew. Holds into the afternoon at 10ft but the wind picks up. This is the best block of surf in the whole outlook.
Thursday the 20th is still 8ft in the morning but wind turns onshore later.
Friday the 21st is a write-off with strong cross-onshore winds, then the weekend cleans up but stays big and windy.
The standouts are Saturday the 15th morning for the punchy east swell and offshore wind, and Wednesday the 19th morning for the big, clean southwest groundswell. That Wednesday session is the absolute pick.
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.
