Thirroul Surf Forecast and Surf Report

G’day, Rusty here. Let’s break down what’s coming for Thirroul. The next couple of weeks have a slow start, but a real meaty pulse shows up in the second week that’s got some juice.

The first surf of note is Sunday 30th August morning. We’ve got a clean 3ft south swell, glassy conditions with no wind, and the combined energy is a moderate 223. It’s not huge, but the conditions are perfect for a fun session on the intermediate gear. Water temp is about normal for this time of year. By Sunday afternoon the wind picks up onshore and kills it, so the morning is the move.

Monday and Tuesday are weak. Monday morning has a glassy 3ft swell but the period is short at 8 seconds, so it’s sluggish. Energy is down around 166. Tuesday afternoon has a bit more energy at 256 with a clean cross-off breeze, but the swell is still only 3ft. Surfable but nothing special.

From Wednesday 2nd September through to Monday 8th September, it’s flat and poor. Swell drops to between 1ft and 3ft, with energy mostly below 100. Winds are often clean or offshore, but there’s just no swell to work with. It’s about a week of nothing worth paddling out for. Might interest the kite crowd on some afternoons with clean offshore wind, but for a surfboard, it’s a bust.

Now, Wednesday 9th September morning brings a change. We get 5ft of south swell at 10 seconds, combined energy of 364 (moderate-strong), and glassy conditions. This is a real step up. The swell direction (S) is a good match for the exposed setup here. This is a standout window.

But the big one is Thursday 10th September morning. Swell hits 7ft from the south, with a combined energy of 925 – that’s strong. The wind is dead calm, glassy perfection. This is expert territory – at 7ft, it’s too big for beginners. The period is 10 seconds, so it’s a solid groundswell that’ll hold good shape, though it might close out on the beach breaks. The reef and points should handle it better. Crowds are possible here sometimes, so you’ll likely have company. Thursday afternoon the onshore wind ruins it, and Friday drops off quickly.

The rest of the second week (Saturday 12th September onward) fades back into small, weak, and messy surf with nothing worth chasing.

So, Sunday morning 30th August is a light warm-up, but the real standout is Thursday 10th September morning. That’s the session to plan for.

Rusty.
