The Lowdown
Hey folks, Rusty here. Let's talk about what's coming up for Magna Tubes.
Right off the bat, this is a tricky outlook for an advanced reef break. The water is sitting at a very unusual 60°, a full 6° colder than normal for this time of year, so you'll want a thick hood and gloves. The first week is a write-off for any decent surf, with a long stretch of poor conditions from the 12th through most of the following week. The winds are mostly onshore or cross-onshore, and the swell is often just messy. There's a gap here of nearly three days with nothing worth chasing.
The first real glimmer of hope shows up on the morning of Tuesday, the 16th of September. That's a standout. We've got a solid 10ft of SW groundswell (moderate wave energy of 3491) with a very long 14-second period. The wind is light and cross-offshore, meaning clean faces. This is a serious, expert-only wave at over 8ft – it's going to be powerful and heavy on the reef. If you're not dialled in, give this one a wide berth.
The next decent session comes a bit later, on the afternoon of Tuesday, the 24th of September. A clean 5ft of SW groundswell (energy of 1487) arrives with a moderate WNW offshore wind. This is a much more manageable size for advanced surfers, and the offshore breeze will put a nice line on those long-period waves. A good, clean option.
Then, to wrap things up, the afternoon of Wednesday, the 25th of September looks promising. We have 8ft of ESE swell with a 10-second period, and a light cross-offshore wind. The wave energy is moderate at 1308. Another clean session for the more experienced crew, but note the shorter period here means it might not have the same grunt as the groundswell options. Keep in mind that Magna Tubes can get crowded sometimes, but when the quality is this good, it's worth sharing the lineup.
So, for the short term, hold your horses. The best bets are the clean, expert-level swells on the 16th and the late clean-up on the 24th and 25th. Those are the ones to circle on your calendar.
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.
