Thirroul Surf Forecast and Surf Report

G’day, it’s Rusty here. Let’s have a look at what’s on the table for Thirroul over the next couple weeks. It’s a bit of a mixed bag, but there are a couple moments that’ll get the heart pumping.

The water temp is sittin’ around 64°, which is pretty much bang on average for this time of year down here, nothing too unusual.

Tuesday the 25th and Wednesday the 26th are pretty ordinary. We’ve got small messy swell with cross-off or cross winds, and the energy is weak to moderate – those numbers around 110 to 266 tell the story. Not worth paddlin’ out for.

But then Thursday the 27th morning – this is where it starts to get interesting. Glassy conditions with that south swell coming in around 6ft at 9 seconds. The energy jumps to 507 (moderate), and with nobody around, it’s lookin’ clean. That’s a solid shout for a morning session.

Friday the 28th morning is another highlight. Clear skies, light cross-off wind from the southwest, and a 5ft SSE groundswell at 11 seconds. The combined energy is 620 (moderate) – good shape, clean faces, and that longer period will mean better waves. This is the standout of the first week.

Saturday the 29th morning sees the swell bump up to 7ft from the south, but the period drops to 8 seconds and it’s a light cross-on wind. The energy is strong at 1146, but that size is gettin’ into expert territory, and it’s a bit junky. Kite surfers might dig it more than paddlers.

Sunday the 30th and Monday the 31st mornings are clean and smaller – around 3ft to 2ft – with glassy or light cross-off winds. The energy is moderate, but it’s more of a fun small-wave session.

Tuesday the 1st of September stays clean with offshore winds and 3ft to 3ft SSE groundswell. Nice and lined up, but small.

Now, the big one: Thursday the 3rd of September. This is the standout of the whole outlook. Morning and afternoon both score top marks. We’ve got a 4ft to 5ft SSE groundswell with a massive 20-second period – that’s very long-period groundswell. The combined energy on Thursday afternoon is 1800 (strong), with a clean offshore wind from the WNW. This is a real clean, powerful groundswell hitting the beach-and-reef set-up. It’ll be a ripper for experienced surfers, but that long period can make beach breaks a bit straight – still, Thirroul’s reef should handle it nicely. Crowds are listed as sometimes, so you might have some company, but it’s worth it.

Friday the 4th and Saturday the 5th of September drop off a bit – still reasonable swell around 5ft to 6ft, but the winds turn cross-on or onshore, and the quality dips. Sunday the 6th has a clean 4ft south swell with offshore wind, but the energy is down.

From Monday the 7th onward it fades into small, weak surf with weak energy (down to 64 on Tuesday the 8th) and ordinary conditions. Not much to get excited about.

Best calls: Thursday morning 27th August for the glassy 6ft south swell, and Thursday 3rd September for that powerful, clean 5ft groundswell with 20-second period and offshore wind. That second one is the real gem.

Rusty.
