Thirroul Surf Forecast and Surf Report

Alright, let’s take a look at what’s comin’ up for the next couple of weeks here at Thirroul. This is a beach and reef setup that picks up a solid SE swell, and the water’s sittin’ right around 64°F, which is bang on average for this time of year – nothing unusual there.

We’ve got a bit of a slow start, but the first real standout is Sunday morning, the 30th of August. It’s glassy, no wind at all, with a clean 3ft southerly swell rollin’ in at 9 seconds. That’s gonna be your best window early on – really clean, really cruisy. The combined energy is moderate at 252.

After that, the surf gets smaller and more ordinary for a few days. Monday the 31st has a glassy 3ft, but it’s short period and weak, so not much push. Tuesday morning the 1st of September has a little more period at 11 seconds and cross-off wind, but the swell’s only 3ft. It’s surfable but nothin’ to get excited about.

Then we hit a real flat spell from about Wednesday the 2nd through to the next week. The combined energy drops right down to around 47 to 137, and the swell is tiny – under 2ft – with short periods. There’s a few days in there with clean offshore winds, but no wave height to work with. It’s a solid gap of about 5 to 6 days with no real surf on offer.

Now, here’s where it gets interesting. On Wednesday the 9th of September, we get a big spike in the morning – 12ft southerly swell at 11 seconds, with combined energy through the roof at 4100. That’s a serious pulse, but the wind is cross-onshore and choppy, and the tide could be an issue. This is expert-only territory, and the conditions are messy, so it’s more of a big-wave challenge than a clean session. Thursday the 10th still has solid 6ft swell but the wind is sideshore, not great.

The best late-period option looks like Friday the 11th of September morning. The swell drops to 4ft from the south, period at 10 seconds, and the wind is light cross-off from the NW – that’s clean. Combined energy is moderate at 274. It’s not huge, but it’s the cleanest window in the second week and worth a paddle.

All in all, the standout is Sunday morning the 30th of August for clean, glassy fun waves. Beyond that, Friday the 11th morning is your next best bet. Don’t hold your breath for the middle of the week – it goes flat for a while.

Rusty.
