Kirra Surf Forecast and Surf Report

G'day, Rusty here. Look, I’ve been staring at the charts for Kirra and, truth be told, this 16-day run is a tough one for a wave this famous. We’ve got a long, quiet gap stretching from now all the way out to Monday, September 7th, with very little to get excited about. The water temp is sitting at 69°F, which is pretty much spot on for this time of year, so no surprises there.

The Opening Days – A Doldrum
From Wednesday, August 26th through the end of the month, it’s basically a write-off. The swell is small, mostly from the ENE or SSE, barely cracking 4ft, and the period is short—around 7 or 8 seconds. That’s weak, wind-affected slop. The combined energy is in the low hundreds (171, 137, 105), which tells you there’s just no grunt. Mornings are cross-shore or onshore, afternoons don’t get much better. There’s a brief window on the 27th and 28th with some clean, offshore wind, but the swell is so small (3ft to 4ft) and weak it’s barely rideable. Honestly, this is a low point. It’s the kind of stretch where you don’t even bother waxing the board.

A Glimmer – Late Month
The last few days of August into early September are still poor. You get a bump in swell on Sunday the 30th, up to 7ft from the SSE, with combined energy hitting 560, but it’s messy—raining, windy, and the period is a short 8 seconds. That’s a lot of chop for not much reward. The mornings of the 31st and September 1st see a clean offshore flow, but the swell drops back to 5ft and then to 2ft. The energy plummets (399 down to 224). It’s like the ocean is teasing you.

The Standout – Monday, September 7th
If you can wait, there’s one proper event on the horizon. Monday morning, September 7th, is the only true standout in this whole outlook. The swell jumps to a very solid 10ft from the SSE, with a combined energy reading over 1000 (1044 to be exact). That’s serious power. The wind is light offshore from the south at just 6 mph, so it will be clean and lined up. But a word of caution: at 10ft, this is expert territory only—far too big for beginners, and even intermediate surfers should be very cautious. The period is a punchy 8 seconds, so it’s a short-interval wind swell, not a long-running groundswell. This break is a point/groyne setup, which is good news—it should handle the size and keep the waves from closing out. It’s sheltered from the SSE swell direction, and the optimum direction is SE, so we’re a little off-angle, but with that much energy, it’ll still fire. The light breeze and clean conditions make it a serious session. Just know that crowds are often an issue here, and on a day like that, it’ll be packed. The afternoon gets too windy, so be an early bird.

The Tail End
After that one good day, September 8th onwards drops back into tiny, weak surf with onshore winds. A few glassy mornings on the 10th, but the swell is a pathetic 4ft with energy around 200. Not worth the paddle.

Final Word
One morning on the 7th is your only real shot. Everything else is a long, flat slog. Wait it out, and if the long-range forecast holds, that Monday dawn patrol will be worth it.

Rusty.
