Magna Tubes Surf Forecast and Surf Report

Alright folks, Rusty here. We’ve got a solid run of surf coming up at Magna Tubes, so let’s get into it.

First up, we’re looking at a reef break that’s fairly consistent, but it’s an advanced spot. The water is sitting at a chilly 59°, which is a massive 7° colder than normal for this time of year – that’s seriously unusual, so you’ll want a thick steamer.

The big news is the swell. We’re talking a powerful SW groundswell pumping in at 12ft with a 13-second period. The combined energy is a massive 4627 (strong to very strong wave energy). That’s not for the faint of heart. The wind is a clean cross-off from the SW at 9 mph, and the morning of Thursday the 6th of August is looking excellent for experienced surfers. This is the standout session of the whole period—big, powerful, and clean.

Thursday afternoon, the wind swings to the SSW and picks up to 16 mph, turning it cross-shore and making things messy. The swell drops a touch in energy (3659) and the quality falls off. Not the call.

Friday the 7th of August looks average. The swell is still 10ft from the SW, but the morning wind is a cross-on from the East at 6 mph, and the afternoon is straight onshore. Not worth paddling out.

Saturday the 8th of August sees the swell easing to 8ft, but the wind is a clean cross-off from the WSW. The energy is still strong (2578 in the morning, 2003 in the afternoon). It’s clean, but it’s a bit of a drop in size and quality from Thursday.

Sunday the 9th of August has a morning window with an 12ft SW swell, cross-off wind, and a massive energy reading of 4087. The forecast is marginal due to some moderate rain, but the waves will be there. By afternoon, the wind swings to a strong 25 mph cross-on from the South, making it a total mess. A morning-only mission.

The rest of the first week and into the second week is a mixed bag of onshore winds and choppy conditions. The swell sticks around in the 6-10ft range, but the wind is rarely your friend. The morning of Wednesday the 12th of August sees the swell tank to 3ft, but with a very long 21-second period – that’s groundswell, but it’s weak and the wind is cross-on. Not worth it.

Now, we get a couple of interesting days in the second week. The morning of Friday the 14th of August has a clean 4ft SW swell with cross-off wind, but the energy is down to 919 (moderate). A mellow option. Then, Saturday the 15th of August afternoon is a real treat: glassy conditions with a 3ft, 16-second SW groundswell. The energy is 885, and the report says “expect very good surf conditions.” That’s a clean, cruiser session for a smaller board.

The real hidden gem might be Tuesday the 18th of August morning. Glassy conditions, a 7ft SW swell, and an energy reading of 1848. The report calls it “excellent surf conditions for experienced surfers.” That’s a solid, clean, powerful session for those who can handle it.

Thursday the 20th of August afternoon also looks promising: a clean 8ft SW swell with light cross-off wind and an energy of 1968. Another one for the experienced crew.

The last few days of the window get blown out by strong winds. No real standouts there.

So, to wrap it up: if you’re experienced and want the biggest, baddest waves, paddle out Thursday morning, the 6th of August. For a clean, smaller, and more manageable session, mark your calendar for Saturday the 15th of August afternoon or the morning of Tuesday the 18th of August.

Rusty.
