The Lowdown
Alright folks, Rusty here. It’s gonna be a slow couple of weeks, so let’s be real about what we’re looking at. For the most part, we’ve got a lot of small, weak surf and a whole lot of "meh." But there are a couple of sessions that look like they’ll be worth the wait, so don’t go shelving the boards just yet.
We're starting off with nothing to get excited about. Monday the 17th is poor, with a 0.8m south swell and an onshore breeze messing it all up. The next few days are much the same: tiny waves and onshore winds. It’s a solid stretch of nothing until Wednesday the 19th in the afternoon. That’s when we finally see some glassy, clean conditions, but the swell is only around 2ft. You could surf it, but it’s not going to be memorable.
The quiet spell continues through the weekend. Swell stays small and the wind stays on it or cross-shore. We do get a glassy afternoon on Sunday the 23rd, but it’s still pretty weak.
Things finally start to turn around as we head into the last week of August. Monday the 24th afternoon is glassy, and you can start to feel the energy building. Then Tuesday the 25th is the first day that really gets my attention. The swell is still small, only about 2-2ft, but the period is up at 16 seconds, which gives it some real punch. With glassy conditions, those waves are going to be clean and lined up. This is the first day I’d call a proper surf day.
Then we get to it. Thursday the 27th sees the energy jump up, with the combined energy levels hitting the 500s. The height is still around 3ft, but that longer period is doing some serious work. There is a light cross-onshore wind, but it’s manageable. This is a serious window.
The big one comes on Saturday the 29th in the afternoon. The swell jumps up to 1.8m, which is around 6ft, with a combined energy of 892. That’s the biggest swell of the entire period. The period is shorter at 10 seconds, but you can’t argue with the size. There will be some lumpiness from the cross-onshore wind, but this is the standout day for anyone looking for some real waves.
After that, the swell backs off quickly. Sunday the 30th afternoon is small again, but with a 17-second period, it should be super clean and glassy. Then it just fades out into small, weak surf for the final days.
So, here’s the bottom line: your best bets are Tuesday the 25th for clean, glassy, long-period waves, and Saturday the 29th afternoon for the biggest, most powerful swell. Tuesday is the safer choice for quality, Saturday is for size. The water is about 27°C, which is right around the average for this time of year, so no surprises there.
It’s a long wait, but there are a couple of gems in there. Keep your eyes on the forecast and be ready to move when the windows open.
