Thirroul Surf Forecast and Surf Report

G’day, Rusty here. Look, I’ll be straight with you – this stretch at Thirroul is a bit of a mixed bag. We’ve got a 16-day window from late August into early September, but the first few days are pretty ordinary. The real action, the standout stuff, doesn’t kick in until Thursday morning the 27th of August, and then again on Friday the 28th. After that, there’s a long gap of poor conditions until the 8th of September, when things look promising again. Let’s paddle through it.

We start off Tuesday the 25th and Wednesday the 26th with nothing to write home about. Small swell around 3ft to 3ft, cross-off winds, and the combined energy is weak to moderate (107 to 193). The waves are surfable but the conditions are messy – just ordinary. Not worth suiting up for.

Then, Thursday morning the 27th – this is where it gets good. The swell pushes up to 5ft from the south, with a period of 9 seconds, giving us a nice moderate energy pulse (405). The wind goes glassy, which is a massive win. The waves will be clean, lined up, and off the hook for intermediates. The water temp is about average for this time of year, so no drama there. Thirroul is a beach and reef setup, exposed to the swell, and the optimum direction from the southeast is a solid match. This is your go-to session.

Friday morning the 28th is another beauty. A 5ft swell from the south-southeast, with a longer 11-second period, means more energy and shape. The combined energy is strong (522), and you’ve got light cross-off winds from the west. The waves will be clean, punchy, and well-formed. The morning is the pick – the afternoon turns cross-on and gets messy.

After that, we enter a dry spell. From Saturday the 29th through to Monday the 7th of September, it’s mostly poor surf. The swell drops, winds get messy, and the combined energy is weak to moderate. There’s a flash of glassy conditions on Sunday the 30th, but with only 2ft, it’s barely worth the paddle. A few days in there have some longer-period swell (17-19 seconds) but that’s too drawn out for a beach break like Thirroul – it’ll break straight, and the strong cross-shore winds will chop it up anyway.

Then, Tuesday the 8th of September – a late reward. The swell comes back at 4ft from the south, with an 11-second period, and the combined energy is solid (303). The wind is glassy again. That morning session will be clean, fun, and worth the wait. The same holds for Wednesday the 9th.

So, to sum it up: the best of the bunch is Thursday morning the 27th of August and Friday morning the 28th of August. Glassy, clean, good energy – don’t miss them. The rest of the run is a write-off, but the 8th and 9th of September offer a decent comeback. Keep your eyes on the horizon.

Rusty.
