The Lowdown
G’day, I’m Rusty. Let’s get into it.
First up, a bit of honesty: this stretch isn’t looking like a classic. Over the next 16 days, the surf stays pretty ordinary for the most part, but if you’re keen to paddle out, there are a couple of very small windows that might be worth a look. The first real surf recommendation doesn’t pop up until Saturday 22 August, so we’re sitting through a few days of lumpy, cross-onshore junk before we get anything borderline. From 17 August all the way through to the morning of 22 August, it’s mostly poor – think 7ft down to 3ft of short period slop, with onshore or cross-onshore winds and moderate to fresh breezes. The water temp at Noosa – Alexandria Bay is running around 68°, which is a bit colder than normal for this time of year.
Saturday 22 August morning is where it gets slightly interesting. The wind goes glassy – calm, with zero wind – and we’ve got 4ft of east swell at 7 seconds. The combined swell energy is weak at 132. The surf is small and pretty ordinary, but it’s clean and surfable. Not a standout, just a paddle to wet the line. The break is consistent, exposed, and can get crowds sometimes, so you might have company.
Tuesday 25 August morning sees a small bump in quality. With a light northwesterly breeze coming cross-offshore, the 2ft east swell at 7 seconds cleans up nicely for a tiny, clean surf session. Combined energy is only 48 – very weak – but the conditions are clean. Again, not a big day, but the only real clean option.
After that, the surf drops off again. From 26 August through to the end of the month, we’re looking at poor, onshore, and choppy conditions, with occasional small pulses but nothing worth getting excited about. The very start of September shows a slight increase in swell energy (240) with 4ft east swell at 10 seconds, but the onshore easterly wind keeps it messy.
Overall, the only real standouts are the glassy Saturday 22 August morning and the clean Tuesday 25 August morning. Nothing for the experts, nothing for the beginners. Just small, clean windows for those who want a quiet paddle. If the wind stays light, it’s fine, but don’t come expecting power.
Rusty.
