Table - best surf conditions forecast for Magna Tubes over the next 16 days.
The Lowdown
Alright, let’s get into it. The only spot on the radar for the next 16 days is Magna Tubes, a reef setup that takes a clean SE swell direction. The water is sitting at 58°F, which is a solid 8°F colder than usual for this time of year — that’s a big chill, so a good thick wetsuit is non-negotiable.
The first real action kicks off Thursday morning, August 27th. We’ve got a 7ft SSW swell rolling in with a 12-second period, and combined wave energy is a thumping 3043 (moderate). The wind is light and cross from the NE, so the surface will have a few ripples but nothing too messy. It’s a solid start, but the tide or something is making it a bit marginal. Still, there’s enough there to get a few.
Friday morning, August 28th, drops a bit to 5ft from the east, period around 10 seconds, and energy drops to 795. The wind is light cross-off from the WSW, so the waves will be clean. It’s not a standout, but a fun little session if you’re keen.
The real standout is Tuesday morning, September 1st. The swell is 7ft from the SW, 11-second period, with energy at 1178 (moderate). The wind is light cross-off from the SW, and the comments say it’s excellent for experienced surfers. That’s the one to circle.
Then things get wild. Wednesday morning, September 2nd, pumps 13ft of SW swell, 14-second period, and energy hits 7164 (very strong). That’s a lot of water moving. The wind is light cross-on from the SE, so it’s a bit bumpy, but for experts only — this is big and heavy. Too big for beginners.
Thursday, September 3rd, is blown out. 16ft of S swell with 25 mph winds from the SSW — just messy and dangerous. Skip it.
Friday, September 4th, is a redemption day. Morning offshore winds from the WNW, 12ft SSW swell, 12-second period, energy at 5863 (very strong). The comments say exceptional for experts. That’s a big, clean, powerful session if you’ve got the skills.
After that, it fades. Saturday and Sunday, September 5th and 6th, are choppy and messy. The following week sees smaller, cleaner waves but nothing special. Monday, September 7th, has a clean 4ft SW swell with light offshore winds — a nice little session for the more experienced.
The last real pulse is Friday, September 11th, with 10ft to 13ft SW swell, but the wind is cross-on, so it’s lumpy. Not ideal.
Overall, the best bets are Tuesday morning September 1st for a solid, clean session, and Friday morning September 4th if you’re an expert after big, offshore power. Magna Tubes is a reef, so those long-period swells (12-14 seconds) will be wrapping around nicely, but beware of the sets — they’ll be fat and powerful.
Stay warm and get out there when it’s clean.

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.
