The Lowdown
Alright, folks, Rusty here. We’ve got a single spot on the table for this outlook – Magna Tubes. It’s a shallow reef setup that takes some serious know-how, so don’t even think about paddling out here unless you’ve got the experience.
The water temperature is sitting at a crazy 53°F, which is a massive 13°F colder than what’s normal for this time of year. That’s far colder than usual, so you’ll want the thickest steamer you’ve got and maybe a hood.
We’re looking at a solid run of swell. It kicks off on Sunday the 16th, with a south-west swell pushing 5ft and a period of 12 seconds. The energy is moderate at 863, and a light cross-off shore wind should keep things pretty clean. Not a standout, but a solid warm-up.
Monday the 17th morning is where it starts to get interesting. The swell jumps to 8ft from the south-west with a 14-second period, packing moderate energy at 2115. The wind is a near-flat calm, making for some seriously clean conditions. This is one of the best windows for experienced surfers.
Tuesday the 18th keeps the quality going. Morning sees 7ft south-west swell at 13 seconds (1689 energy), and the afternoon builds to 8ft at the same period (2251 energy). Winds stay light and cross-off, keeping the waves clean.
Wednesday the 19th morning is a real standout. We’ve got 10ft of south-west swell with a 13-second period, and the energy is strong at 2451. The wind turns offshore from the north-west, glassing it right up. This will be thick, powerful, and clean – for experts only. The afternoon gets a bit hairy with 19 mph winds, so get your session in early.
Thursday the 20th is for the brave. The swell hits 13ft from the south-west (14-second period), and the energy is very strong at 5178. Morning winds are manageable, but the afternoon gets a cross-shore chop. Even for experts, this is pushing into the big and unruly zone.
Things start to decline from Friday the 21st. We get a 8ft south-west swell, but the wind turns onshore and it looks sloppy. Saturday the 22nd is a mess with a short-period 10ft swell and fresh winds.
Then on Sunday the 23rd, the models try to throw a 20ft south-south-west swell with 15-second period at us. The energy is extreme at 16355. But the word is, it’s simply too big for this break – the ocean will be a washing machine. Monday the 24th is still massive at 16ft, but the wind drops and it cleans up for a possible expert-only session.
After that, Tuesday the 25th through Saturday the 29th is mostly blown out or onshore, with a few clean windows in the mornings. The standout in the second week is Sunday the 30th morning – a clean 7ft south-west swell with a 12-second period (1246 energy) and light winds. A good, solid option to end the period.
Best Bet: If you’re an expert, Wednesday morning the 19th is your high-water mark: 10ft, offshore wind, clean and powerful. For the less intense surfer, Sunday morning the 30th offers a more manageable size with clean conditions.
Stay safe, and wear the rubber.
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.
