The Lowdown
Howdy, Rusty here.
Let’s cut to it. For the next week to ten days, Magna-Tubes is going to be pretty grim. You’ve got persistent onshores and that choppy, cross-chop mess—not good for much. Water’s at 61°F, which is running a few degrees colder than usual for this time of year, so don’t skimp on the rubber.
The one to save for is next Friday, the 25th. That’s the clear standout. We’re looking at a big SW groundswell building to 13ft with a 16-second period. The morning looks clean, glassy, with a light offshore wind, and the energy is off the charts at 7974. This is serious, expert-only surf. If you’re comfortable out back, this is the pick of the whole forecast.
The 27th morning is also a good shout. Glassy and clean, with a 7ft SSW groundswell swinging around a 13-second period. It’ll be fun before the east wind glass over it later in the day.
The rest of the run is mostly skip-it. The 20th has a 11ft, 8-second windswell and onshores—that’s a mess. The 23rd and 24th bring in more big, raw SW energy, but the winds stay cross-onshore, chopping it all up. Then it just fades out into nothing by the 30th and 1st, with tiny 2ft leftovers and not much push.
So, do yourself a favor and point yourself at the 25th. The 27th morning is a solid backup. Otherwise, it’s a waiting game until things clean up.
Rusty out.

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.
