Table - best surf conditions forecast for Magna Tubes over the next 16 days.
Hey, Rusty here with the 16-day outlook for Magna Tubes. This reef needs a proper SE swell to light up, and the forecast is a real rollercoaster. The good news? There are some absolute bombs coming if you've got the skills.
Sunday the 12th is a no-go. A messy 6ft SSW swell with a cross-on breeze—leave the board in the car.
Monday the 13th morning is where it starts. Glassy conditions and a 7ft E swell. It's short-period (8 seconds), so a bit lumpy, but the clean surface makes it a solid option for experienced surfers. The wave energy is strong (1348). The afternoon turns onshore, so be on it early.
Tuesday the 14th morning is a gem. Dead glassy with a clean 6ft ESE swell (9 seconds, moderate energy of 683). This is the pick of the first week—really nice, clean lines on the reef.
Wednesday the 15th drops off to 4ft to 4ft E swells, clean all day but nothing special.
Now, listen up. Thursday the 16th morning is a big one. A 10ft SW swell with a very long 14-second period and light offshore cross-off wind. This is powerful, excellent surf for experts only—wave energy is sky-high at 3431. Thursday afternoon holds at 8ft, still clean.
Friday the 17th is massive. A solid 13ft SW swell, 12-second period, with a clean cross-off breeze in the morning. The energy is pumping at 4518. Only the most hardcore crew should even think about it. The afternoon gets a bit crossed up.
Saturday the 18th is a write-off. Strong cross-onshore winds and a lumpy, choppy 8ft S swell. Hard pass.
Sunday the 19th bounces back. Clean cross-off wind and a fun 8ft E swell in the morning, easing to 6ft in the afternoon. Excellent for experienced surfers.
Monday the 20th drops to a weak 4ft E swell with moderate wind—marginal. Tuesday the 21st is blown out by strong winds and a weak, short-period swell.
Here's the next standout. Wednesday the 22nd morning brings a solid 8ft SSW groundswell (14-second period) with a clean offshore wind. Energy is 2279. The afternoon turns glassy with a 6ft swell. Beautiful.
Thursday the 23rd gets messy again—a big 10ft swell but with a choppy cross-onshore wind.
Now, circle Friday the 24th and Saturday the 25th. Friday morning: a 7ft SSW swell with a staggering 17-second period—perfect for this reef. Light cross-off wind, clean wave energy of 4085. It builds to a 10ft swell by afternoon. Saturday the 25th is firing: 12ft SSW swell (13-second period) with clean offshore winds. Energy is over 4500. These two days are the absolute peak of the outlook for experts.
The run fades through Sunday the 26th and Monday the 27th as the swell drops and wind turns against us. The biggest windows are the 16th and then the 22nd through the 25th. If you're charging, those are your days.
Keep your wits about you.
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.
