The Lowdown
G'day, Rusty here.
Alright, let’s have a look at what’s coming our way. We’ve got a bit of a slow start, but things are shaping up to get very, very interesting.
The first proper surf window kicks off on Monday the 24th of August. The morning looks solid with a 8ft swell out of the SW, and a light offshore wind keeping it clean. The wave energy is pumping hard at 2292. This is serious, powerful stuff – definitely not one for the beginners at this size. It’s a reef break for the experienced crew.
Tuesday the 25th and Wednesday the 26th are a write-off, unfortunately. The wind swings cross-on and the quality drops right out. Choppy, messy conditions. A bit of a lull.
Thursday the 27th brings a nice reprieve. The swell backs off to a more manageable 5ft, still out of the SW, and the offshore wind returns in the morning. It’s clean and much more inviting. The afternoon cleans up even more with a light cross-off breeze. A good day for those who want to get back in the water without the heavy-duty grunt.
Now, Friday the 28th of August is where we need to sit up and pay attention. We’ve got a 10ft swell out of the WSW with a very long 17-second period – that’s proper groundswell energy (5615). The morning has a gentle offshore wind. This is going to be a standout session for expert surfers only. The power and the lines will be exceptional, but that size and period on a reef means it’s not a place to be casual. The afternoon stays clean with a 16-second period.
Saturday the 29th is still solid at 7ft with a clean offshore wind in the morning, but the afternoon gets messy with onshore wind. Sunday the 30th looks glassy in the morning with a 6ft, 17-second swell – a beautiful, clean morning session for the experienced.
Then we hit another massive pulse. Monday the 31st of August through Tuesday the 1st of September sees the swell holding at a consistent 10ft. The Monday morning is absolutely pristine with a 15-second period, offshore wind, and a massive 5250 energy reading. This is another true standout – a clean, powerful, expert-only day. The energy is just enormous.
Wednesday the 2nd of September keeps that 10ft swell running, though a moderate breeze picks up. It’s still clean but more wind-affected. From Thursday the 3rd through to Friday the 4th, things drop off and get messy again with cross-onshore and choppy seas.
But hold on – Saturday the 5th of September is a monster. The afternoon shows a 13ft swell out of the WSW with a 16-second period. The combined energy is a staggering 8000. The wind is cross-off, keeping it clean. This is for the absolute elite only. It’s huge, powerful, and dangerous.
Sunday the 6th of September follows that up with another 13ft swell, but this time with a moderate offshore wind (12 mph). That is a rare, powerful combination. The energy is still through the roof (6886-7372). Another day for experts only.
After that, things turn ugly. Monday the 7th and Tuesday the 8th of September get blown out with strong onshore winds and massive, unrideable swell. The wave energy hits 10942, but with a 16 mph cross-onshore wind, it’s just a washing machine. That’s a full close-out.
The standout sessions without a doubt are Friday the 28th of August and Monday the 31st of August for the clean, powerful, long-period groundswell with perfect offshore winds. Saturday the 5th and Sunday the 6th of September are for the absolute pros only – massive, clean, but not for the faint-hearted.
Keep your eyes on the horizon.
Rusty.
