Thirroul Surf Forecast and Surf Report

G’day, Rusty here, and I’ve had a good look at what’s on the cards for Thirroul over the next couple of weeks. It’s a mixed bag, with a pretty flat start and a couple of windows that might get you excited, but you’ll need patience.

The first bit of action we’ve got is Thursday morning, the 13th of August. It’s not huge, but it’s our best early call. We’ve got a 4ft south swell with a 9-second period, and the combined energy is moderate at 212. The wind is a light cross-off from the WSW at 6 mph, which will keep the beach and reef setup pretty clean. The water temp is about average for this time of year, nothing wild. It’s not a standout for size, but it’s surfable and the conditions are good. Thursday afternoon fades a bit with an onshore wind, so the morning is the pick.

After that, it gets ordinary. Friday morning the 14th has a 3ft south swell with glassy conditions from a WSW breeze at 3 mph—that’s light and clean, but the swell is weak with only 157 combined energy. Friday afternoon and everything through to the end of the following week looks poor. There’s a south-southwest swell pushing through on the 15th and 16th, but it’s messy with strong onshore winds and rain, making it choppy and unappealing. The 17th and 18th stay poor with small, weak swell and onshore winds. It’s a real lull, and honestly, this stretch is more interesting for kite surfing than paddle surfing with the wind and chop.

We get a small glimmer of hope on Wednesday the 19th. Morning glassy conditions with a 2ft east swell, and the afternoon picks up to 4ft east swell, both glassy with light winds. The combined energy is weak to moderate (77 and 127), so it’s small, but it’s clean. This pattern of small, clean surf continues through the 20th, 21st, and 22nd, with morning cross-off winds and tiny swell in the 2ft to 3ft range. Nothing to write home about, but if you’re desperate, you’ll find something.

Now, the real standout comes on Sunday the 23rd of August. The afternoon session is the highlight of the entire outlook. We’ve got a 4ft swell from the ENE with a 9-second period, and the combined energy is moderate at 223. The wind is a solid offshore from the west at 12 mph, keeping it clean and well-shaped. This is a beach and reef setup, and with that offshore breeze, it’s going to be fun. The morning is also okay with a 3ft ENE swell and offshore wind, but the afternoon is the pick. This is the one to circle on your calendar.

Through the 24th and 25th, the swell drops back to 2ft-3ft from the ENE, with clean offshore winds, but it’s pretty ordinary. The energy is moderate but not special.

Then we get a big change on Wednesday the 26th of August. The morning brings a 6ft south swell with a 10-second period, and the combined energy is strong at 679. The wind is a gentle cross-shore from the SSW, so it’s not perfect but it’s manageable. This is a solid groundswell, and it’s going to offer some punch. However, the afternoon sees a 12ft south swell from the same direction, with a very long period of 11 seconds and massive energy of 4843. That’s huge, but the wind is a moderate cross-on at 16 mph, making it choppy and only for experts. The 27th and 28th have smaller south swells around 4ft-5ft, but the wind stays onshore or cross-on, so it’s not great.

So, for the best bet, I’d say Sunday the 23rd of August afternoon is the standout. The 4ft ENE swell with offshore west wind gives you clean, fun waves at Thirroul. The 26th morning could also be interesting for experienced surfers, but it’s a bit rougher. Keep an eye on the long-range—it’s promising but less certain. Stay patient, and you’ll get a session.

Rusty.
