Kirra Surf Forecast and Surf Report

Alright, Rusty here. Let’s have a look at what's coming down the line for the next couple of weeks.

Right off the bat, I’ve got to be straight with you. The start of this run is dead. For the first several days, we're staring at tiny, onshore mush. It's not worth paddling out for. Water temp is sitting at 70°, totally bang on average for this time of year.

Now, hang in there because things are going to get bloody interesting. The real show starts on September 16th. Wednesday morning, we get a kick of 7ft south swell with a fresh offshore blowing, and the combined energy jumps to 333 (moderate). That's a good sign. But by Wednesday afternoon, it steps up big time: 10ft of SSE swell, period around 8 seconds, and the combined energy is a massive 1266. That's strong energy. This is not for the faint-hearted. With over 8ft of swell, this is strictly for the experts. The offshore wind will keep it reasonably clean, but that's a lot of water moving around.

Thursday the 17th is the standout. Morning session sees 10ft from the SSE, period stretching to 10 seconds, and combined energy hits an impressive 1645 (very strong). Winds are offshore, moderate but clean. This is big, powerful groundswell at Kirra. That long period (10 seconds) is going to groom those famous point breaks beautifully. Expect long, lined-up waves, but those sets will be widely spaced. Crowds are likely here as it's a top spot, but for the experienced surfer, this is the pick of the period. The wave direction (SSE) is slightly off from Kirra's optimum (SE), but the sheer size and power will make it work.

Into Friday the 18th, we drop back to 6ft SSE swell with lighter winds, energy at 472 (moderate). It's surfable but nothing special. Saturday and Sunday fall away again into the small stuff.

After that, we hit a long flat spell. From around the 21st through to the end of the month, it's mostly poor. We see some 5ft to 6ft swell from the east-northeast, but the wind is either onshore or cross-onshore from the north-northeast. The combined energy fluctuates between 220 and 499 (weak to moderate), so it's not hitting with any authority. The low period (6-9 seconds) means it'll be weak, sloppy windswell. It's not worth your time.

So, the bottom line: next week, Wednesday the 16th and Thursday the 17th are your only real chances. Thursday morning with that 10ft, 10-second groundswell and offshore wind is the absolute best on offer. Get your big-wave gear ready, but know your limits—this one’s for the chargers only.

Rusty.
