The Lowdown
Alright, let’s put it in feet and all that. Only spot we’ve got is Magna Tubes — a proper heavy reef slab that’s not for the faint-hearted. The water’s sitting at 64°, which is a bit cooler than normal for this time of year, so you’ll want a thicker suit.
The standout session is Monday 20 July morning: 8ft SW swell, glassy, with a light ENE breeze. The energy is solid (1467), and the 11-second period means clean, punchy sets. Great for experienced surfers, but expect some company.
Wednesday 22 July afternoon brings 8ft SW, cross-off wind, and energy jumps to 4338. The 13-second period will have the reef working nicely, but it’s big enough to keep the beginners on the beach.
Thursday 23 July morning: 12ft SW, glassy, NE breeze, and 3178 energy. This is serious size — only for those who know what they’re doing.
The absolute best of the run is Friday 24 July morning. We’re talking 12ft SW, a very long 16-second period, glassy conditions, and a massive 6095 energy reading. This is exceptional, but it’s for experts only. The reef will be a freight train.
Saturday 25 July is still big but the wind turns ugly, so quality drops. Monday 27 July morning offers a clean 8ft SW with offshore NW wind — another good one for the experienced.
Tuesday 28 July morning drops to 6ft SW and glassy, still fun but smaller. Then Wednesday 29 July through Thursday 30 July sees poor wind and fading swell — not worth the paddle.
Late in the run, Friday 31 July both morning and afternoon deliver 13ft SW with cross-off NNW wind and energy in the 5000s. That’s massive, shallow reef — only for the brave.
The top pick: Friday 24 July morning. Second best: Monday 20 July morning. After that, pick your windows carefully. Over 8ft, it’s expert-only. This reef handles the long-period groundswell well, but don’t underestimate it.

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.
