Thirroul Surf Forecast and Surf Report

Alright, this is Rusty, and I’m looking at what’s on the cards for the next couple of weeks here at Thirroul. It’s a beach and reef setup, and it’s gonna be a real mixed bag. We’ve got a bit of a wait for anything decent, so grab a coffee.

First up, the opening days are a write-off. Wednesday and Thursday are messy with onshore winds and choppy, poor surf. The energy is there but it’s all over the shop. We’re looking at a moderate combined energy (250) on Thursday arvo, but it’s a bumpy 5ft from the south with a short, weak period. Not worth paddling out for.

Thursday morning has a bit more size, 6ft, but it’s still cross-on and a bit raw. The energy jumps up (572), but the quality is marginal. Friday is similar, with a 5ft SSE swell and a bit more period (11 seconds) in the morning, but that cross-shore wind won’t do it any favours.

Now, here’s where it gets interesting. The standout is Saturday morning, 29th August. We’ve got a glassy, 4ft SSE groundswell with a solid 10-second period, and the combined energy is pumping at 775. With the wind dead flat, it’s going to be clean. This is the best bet of the whole run. For a surfer, this is where you want to be. The water temp is about average for this time of year, so no surprises there.

Sunday morning, 30th, is also nice with glassy conditions and 4ft of SSE swell, but the energy is a bit lower (276). Still a good session, but Saturday is the pick.

After that, things drop off. The start of the new week sees a tiny, long-period swell (17 seconds) on Monday morning, but it’s only 2ft with a moderate cross-shore. That long period makes it tricky for a beach break, but the reef might hold a little shape. Not much to write home about.

Tuesday, 1st September, is a bit of a consolation. Clean, small waves (3-3ft) from the SSE with an offshore wind. It’s mellow, but you’d be fighting for scraps.

Then we hit a real dry spell. From Wednesday, 2nd September, right through to the 5th, it’s tiny, weak, and mostly poor. The energy is dropping into the double digits (76, 59, 27). This is a real lull in the action.

There’s a flicker of life on Sunday, 6th September. The morning brings a clean 6ft from the south with a gentle offshore, but the period is short (7 seconds) and the wind picks up strong in the arvo, ruining it. The energy is back up (485), but it’s a short, dumpy swell.

The following week is a sad story. Mostly poor, blown-out surf. The only note is Thursday, 10th September, where we get a pulse of 8ft S swell with a clean cross-off wind. That’s big, expert-only territory, and the period is short (8 seconds), meaning it’ll be a bit of a close-out unless you’re on the reef. The energy is hefty (688), but it’s a rough, powerful wave.

So, to put it plain: Saturday morning, 29th August, is your day. Get on it. The rest of the two weeks is a mix of average, small, or blown-out. Stick to the glassy windows.
