Kirra Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get straight into it. The next sixteen days are a bit of a mixed bag, but there’s some serious firepower brewing for the dedicated crew.

The outlook starts with a big fat dud. From Monday the 31st of August right through to the morning of Wednesday the 9th of September, there’s basically nothing worth paddling out for. That’s a solid nine-day stretch of flat, weak, or messy conditions. Small swells, onshore winds, and a bunch of "poor surf conditions" flags. A few clean moments appear, but the swell is just too tiny to get excited about. You’d be better off polishing the wax off your board.

Things finally start to change on the morning of Wednesday the 9th. A solid pulse of south swell arrives, hitting Kirra with 6 ft of swell, a 7-second period, and a clean 19 mph offshore wind. The combined energy comes in at a moderate 315. It’s not perfect, but it’s a real sign of life. By the afternoon, the swell bumps up to 10 ft from the SSE, but the quality is questionable due to tide. Still, the offshore wind is blowing fresh.

Thursday the 10th keeps the size up with 10 ft to 12 ft SSE swell, but again, the guidance flags it as marginal. The energy is strong, hitting 2250 to 2277, and the wind is cross-offshore. It’s a bit raw, but there’s power in the water.

Now, the standout window. Friday the 11th of September morning is the one to circle. Kirra gets a 15 ft SE swell, a 10-second period, and a solid 12 mph offshore wind. The combined energy is a massive 4234, which is serious, heavy water. The guidance says "excellent surf conditions for experienced surfers," and that’s no joke. This is big, powerful groundswell. At 15 ft, this is strictly for experts. The long period (10 seconds) means it’ll have good shape, but at a point break like Kirra, it should line up beautifully. The water temp is sitting at 69°, which is about normal for this time of year.

The afternoon of the 11th is still big at 13 ft, but the wind swings cross-offshore and the quality drops a notch. Saturday the 12th is still pumping with 12 ft in the morning and 10 ft in the afternoon, all clean and cross-offshore, but not quite as pristine as Friday morning.

After that, the swell slowly fades through the 13th and 14th, dropping from 7 ft down to 5 ft, with clean conditions but the surf quality gets downgraded again. By Tuesday the 15th, it’s back to small, clean but unremarkable lines.

So, the clear winner here is Friday the 11th of September, morning session at Kirra. Big, powerful, offshore, and for the brave only. The water is average temp, the wind is perfect, and the swell is heading from the SSE, which is very close to the optimum SE direction for this spot. Crowds are likely here, especially on a day like that, so get there early or accept the pack.

For the rest of the run, Wednesday the 9th morning offers a decent warm-up, but the real gold is on the 11th. After that, it’s a slow fade back to small stuff.

This is Rusty, signing off. Stay wet, stay keen.
