Kirra Surf Forecast and Surf Report

Look, I’ll be straight with you. For the next two weeks, this Kirra stretch is looking pretty grim. The first few days are a washout, and even when there’s a bit of size, the quality just isn’t there. The forecast is a flat spell for the most part, with a few tantalising pulses that never quite line up with the wind. The water temp is about normal for this time of year, sitting at 69°F.

We start off on Tuesday, August 25th with a light wind from the NNE, but that’s straight onshore. The swell is a weak 4ft from the ENE, short period at 8 seconds, and the combined energy is a measly 199. It’s poor. This continues through Wednesday and into Thursday morning, though on Thursday the wind swings south and goes offshore. The swell drops to 2ft from the east, and the energy is weak at 92. It’s clean, but tiny. Thursday afternoon picks up a bit with a 4ft SSE swell, but the period is just 6 seconds, so it’s bumpy and messy.

Friday the 28th is the first real tease. A glassy morning with 3ft from the south, period 8 seconds, and a combined energy of 219. That’s clean but small. Then Saturday the 29th morning sees a jump: 5ft from the SSE, period 10 seconds, and a moderate energy of 522. The wind is offshore from the south. It’s surfable, but the conditions are still ordinary. The best-looking window is Sunday, August 30th. The swell builds to 7ft from the SSE, period 9 seconds, and the energy jumps to 922. The wind stays offshore from the south. It’s a solid size, but at 7ft, it’s getting into the zone where beginners might struggle. The period is short, so it’s not a long, clean groundswell, and the comments say “marginal surf forecast or questionable tide conditions.” Still, it’s the biggest and most consistent day of the first week. The energy is moderate to strong (1054 in the afternoon).

After that, it drops off hard. Monday the 31st is still clean with a 6ft SSE swell, but the energy is down to 483. Then we hit a flat spell from Tuesday, September 1st through to Thursday, September 3rd. Swell is tiny, 2ft, with weak energy (around 114-160). The winds are onshore or cross-onshore, so it’s useless.

Friday, September 4th is interesting but weird. The swell is only 3ft from the SSE, but the period is a massive 19 seconds – that’s a very long period groundswell. The energy is strong at 600, but for a point break like Kirra, that long period will likely make the wave break too straight. The wind is cross-offshore, so it’s clean, but the combination of tiny swell and very long period means it’s probably not going to shape up well. It’s a tease.

The rest of the second week, from Saturday the 5th through Wednesday the 9th, is dominated by weak swell (2ft to 5ft) with poor onshore or cross-onshore winds. The energy is low to moderate (71-300). The only spark is Wednesday the 9th afternoon, with a 5ft SSE swell, period 8 seconds, and a clean offshore wind from the south, but the energy is only 284 – it’s just not enough.

Honestly, the standout is Sunday, August 30th. The 7ft to 8ft SSE swell, with offshore south winds, gives you the best chance of a wave. But it’s not a classic Kirra day. The period is short, and the energy is just moderate to strong. For a point break, that’s a bit disappointing. The rest of the run is a hard pass. If you’re desperate, that Sunday morning is your only shot, but don’t expect perfection.
