Thirroul Surf Forecast and Surf Report

G’day, Rusty here. Let’s break down what’s on the cards for Thirroul over the next couple of weeks. It’s a bumpy ride, but there’s a couple of solid windows to keep an eye on.

We start this Sunday, the 30th of August, with a bit of a teaser. Early morning is glassy, with a clean 0.9m south swell at 9 seconds, and the water temp is a normal 64°. The energy is moderate (223), and it looks good. But it’s a short-lived clean spell – the afternoon turns onshore and it’s over.

Monday the 31st has a glassy morning again, with that same 0.9m south swell, but the period drops to 8 seconds. It’s surfable, but just okay. From there, the rest of the week into the weekend is pretty flat and messy – small waves under 3ft, with onshore or cross-shore winds blowing it out. There’s a stretch from Wednesday the 2nd through Saturday the 5th of September where there’s almost nothing worth paddling for.

Now, here’s the big shift. On Sunday the 6th of September in the afternoon, a massive 13ft south swell shows up, but the period is only 10 seconds and the wind is onshore. The energy is extreme (3001), but the quality is cooked. That one is for the kite surfers, not a paddle board.

The real standout is Monday the 7th of September. Both sessions are looking excellent. Morning brings a solid 7ft southeast swell at 9 seconds, and it stays around 7ft in the afternoon. The energy is strong (918 in the morning, 681 in the afternoon). With light winds and clean conditions all day, Thirroul will be cranking. At that size, it’s for intermediate to expert surfers only. Crowds can be a factor here, so get in early. This Monday is your pick of the whole forecast.

After that, it’s back to rough conditions. Tuesday the 8th through Friday the 11th is mostly onshore and choppy, with swell around 3ft to 5ft but poor quality. There’s a bump in size on the weekend of the 12th and 13th, up to 5ft to 6ft, but the wind is messy and the period is short (6-7 seconds), making for weak, crumbly waves.

Then, on Monday the 14th of September, we get another decent morning. Clean conditions with a 6ft northeast swell at 8 seconds, and the energy is solid (549). The afternoon pushes up to 7ft with similar quality. It’s a good option, but Monday the 7th is still the clear winner.

Bottom line: clear your schedule for Monday the 7th of September. The rest is mostly small or blown out, with a couple of other clean but smaller windows.

Rusty.
