Thirroul Surf Forecast and Surf Report

G’day, I’m Rusty, and I’ve been watching the charts for the next couple of weeks. Let’s be real here – it’s a bit of a slow start, so don’t bother paddling out just yet. The first real surf worth talking about doesn’t show up until Monday the 31st of August, so you’ve got a few days of flat or pretty ordinary conditions to sit through before that.

Alright, let’s get into it. The standout for the whole run is shaping up to be Thursday the 10th of September at Thirroul. That morning, we’re looking at a solid 5ft swell from the SSE, with a long period of 12 seconds – that’s proper groundswell energy, and it’s going to wrap into the beach and reef setup nicely. The wind is light and cross-offshore from the west, which means the faces will be clean and lined up. Combined wave energy is sitting at 540 (moderate to strong), so there’s some real grunt in the water. This is your best chance for a quality session, but keep in mind that with a long period swell like this, the sets might be a bit spread out, and it can break a little straight on the beach – so work the reef sections if you can. The water temperature is 64°, which is about normal for this time of year, so no complaints there.

Before that, Monday the 31st of August morning is a decent little warm-up. Thirroul will have 3ft from the south, with a short period of 8 seconds, so the waves will be a bit weaker and more frequent. The wind is light and cross-offshore from the north, keeping it clean. The energy is 228 (moderate), and while it’s not big, it’s surfable and should be fun. Just be aware that crowds can pop up at Thirroul sometimes, so get in early.

Tuesday the 1st of September morning is similar – 3ft from the south with an 11-second period, which is a touch longer for better shape. Cross-offshore wind from the north again, clean conditions, and energy at 214 (moderate). Solid, but nothing to write home about.

Now, Saturday the 12th of September morning is another standout. Thirroul gets a 6ft swell from the SSE, with a 10-second period and light cross-offshore wind from the north. The combined energy jumps to 757 (strong), so there’s a lot of power in the water. That’s getting into the territory where it’s more for experienced surfers – over 8ft and it’s expert-only, but 6ft is still a fun, punchy size for intermediates who know what they’re doing. The wind is light, so it’ll be clean, but again, long period swells can straighten out at the beach, so look for the reef.

Most of the other days are either too small, too windy, or just ordinary. There’s a gap from the 1st of September afternoon through to the 7th of September where the surf is mostly under 2ft or blown out, so don’t expect much. The second week is a bit of a mixed bag, but the 10th and 12th are the ones to pencil in.

Overall, the near-term stuff is reliable, but the long-range standouts like the 10th and 12th are promising but a little less certain at this stage. Keep an eye on the wind shifts.

Rusty.
