Kirra Surf Forecast and Surf Report

G’day, it’s Rusty. Look, I’m not gonna sugarcoat it – the next week-plus is a real struggle. We’ve got a long, flat, weak stretch ahead with barely a ripple worth paddling for. Then, just when you’re about to give up, a proper pulse of groundswell lines up mid-week the following week that could turn things right around. Let’s walk through it.

The whole run kicks off dead quiet. From Saturday the 29th of August right through to Tuesday the 8th of September, it’s pretty much a write-off. Sure, early on there’s a little bump from the SSE – 5 ft down to 3 ft – but the wind is mostly cross-off or onshore, and that combined swell energy is low to moderate (771 dropping all the way to 20). Not a single one of those sessions scores higher than a 1 out of 10 in my book. You could go for a float, but don’t expect a wave worth mentionin’. There are patches of glassy conditions on the morning of Friday the 4th of September, but with a swell of only 1 ft and combined energy at 63, you’re better off takin’ a sleep-in.

Then we hit a shift. Wednesday the 9th of September – that’s where the story changes. The morning rolls in glassy, and the swell jumps to 8 ft from the SSE, with a period of 9 seconds and combined energy of 984 – that’s moderate to strong energy. It’s a big, clean start. By the afternoon, the swell drops a touch to 8 ft (still SSE, 10 seconds), but the energy climbs to 1102, and the wind stays cross-off and light. Thursday the 10th of September morning might just be the standout: a solid 8 ft from the SSE, 10-second period, offshore wind from the SSW at 9 mph, and the combined energy hits 1382 – that’s strong energy. This is big, punchy groundswell. Now, at 8 ft it’s in the expert-only zone – too much for beginners. And with a 10-second period, it’s not that super-long stuff that races past beach breaks; it’s got shape and push. Kirra is a point/groyne, and that’s a good thing for a swell like this.

Keep in mind, the water temp anomaly is “-” which means it’s about average for this time of year, so you won’t need a steamer, but the air’s clear and the morning breeze is gentle – lovely for a session.

After that peak, Friday the 11th of September still has 6 ft from the SE, clean and offshore in the morning (combined energy 773), but it’s nothin’ special – surfable but ordinary. Then by Saturday the 12th the swell drops off again, and the wind swings onshore and messy.

So my call? The only true standout is Wednesday the 9th of September morning, with that glassy start and 8 ft of SSE swell, and Thursday the 10th of September morning, with similar size and clean offshore wind. That’s the window. The rest of the 16-day run is either flat or marginal.

Rusty.
