The Lowdown
Alright, mates, Rusty here, and we’re dialling into Magna Tubes for the next couple of weeks. It’s a proper reef, likes a bit of size, and it really wants that SE swell. The water’s at 64°, which is a bit chillier than normal for this time of year, so bring a hood.
The first one to get excited about is Friday the 17th afternoon. Glassy, dead calm, with an 8ft SW swell, 11-second period. The energy is solid at 1568, and it’s excellent surf, but this is for the advanced crew only.
Saturday the 18th morning is a smaller, cleaner option. A 4ft swell with a gentle offshore from the W, 11-second period. It’s tidy and fun.
Sunday the 19th afternoon gets big but messy. 12ft swell, but the wind is howling at 35 km/h cross-off. It’s a poor, churned-up mess for experts only.
Monday the 20th morning is a cracker. Glassy again, 7ft SW swell, 10-second period, strong energy at 1397. Excellent conditions for the experienced.
Tuesday the 21st morning is a special one. Glassy, 5ft swell, but the period jumps to 15 seconds – that’s proper groundswell. It’ll wrap beautifully on the reef. Energy is 1234, and it’s clean.
The absolute standout is Thursday the 24th of July morning. Glassy calm, a massive 12ft SSW swell with a 16-second period, and the energy is huge at 5742. This is exceptional, but it’s for experts only.
Friday the 25th morning keeps the quality high – 10ft SW swell, 14-second period, glassy, strong energy at 3627. Excellent for experienced surfers.
Then the wind turns. Sunday the 26th has heavy rain and a 45 km/h cross-on. The swell is still big, but it’s a total washout. That pattern hangs around for a few days of choppy junk.
Wednesday the 29th morning offers a clean break – 5ft SW swell, light cross-off breeze, moderate energy at 1158. A nice, clean session.
The final days, Thursday the 30th and Friday the 31st, shift to an E swell, 10ft to 7ft, with a short 10-second period. The wind is cross-off, so it’s clean, but the energy is moderate.
The one to pencil in is Thursday the 24th of July morning. That’s the big one. Monday the 20th morning is a solid runner-up.
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.
