The Lowdown
Alright, Rusty here for the imperial version. Let’s talk Magna Tubes.
The first real surf shows up Tuesday, July 21st. Water temp is about 63°F, running a couple degrees cooler than usual for this time of year, so you’ll feel it.
Tuesday morning at Magna Tubes (reef break, advanced only) has a 6ft SW swell with a 15-second period – that’s proper groundswell, long lulls between sets, but plenty of energy. Combined swell energy is strong at 1756. Glassy conditions with a light WSW breeze at 3 mph. The swell direction is from SW, which works well for this SE-optimum break. It’ll be clean and punchy, but expect some company – crowds are possible here sometimes.
Wednesday the 22nd morning keeps the quality with a 7ft SW swell, 12-second period, and a clean cross-off breeze. Energy is still strong at 1705. Aim for the morning; the afternoon gets windier and messier.
Thursday the 23rd morning is smaller at 5ft SSW, clean but moderate energy at 797. Thursday afternoon jumps to 12ft SW – only for experts, and the wind adds some chop.
The big standout is Friday July 24th morning. Magna Tubes is going off. A 13ft SSW swell with a 16-second period – very long-period groundswell, massive energy at 8411. Light cross-off wind at 3 mph, clean as glass. This is exceptional, but at over 8ft it’s strictly for experts. The long period will make it fast and hollow on the reef – a proper session if you’ve got the chops.
Saturday the 25th and Sunday the 26th have onshore winds, not great. Monday the 27th morning is poor with 40 mph wind and only 4ft swell. The afternoon goes to 10ft but still windy.
Tuesday July 28th morning has offshore wind at 30 mph with 8ft SW swell – clean but windy. Wednesday the 29th morning is another good one: 10ft SSW, 15-second period, light air and clean. Thursday July 30th morning is glassy with 7ft SW swell.
August starts rough. August 1st morning is flat at 1ft, afternoon blows up to 20ft SW but with strong cross-onshore wind – better for kiteboarding. August 2nd is similar size with gentler wind but still choppy.
August 4th afternoon has a 7ft E swell with 8-second period – short period, not much energy – but clean and could be fun.
Best bet: Friday morning July 24th – huge, clean, and only for pros. Mornings on the 22nd, 29th, and 30th are solid too.

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.
