Thirroul Surf Forecast and Surf Report

G'day, Rusty here. Let’s have a look at what’s coming up for Thirroul. This stretch has a solid SE swell window, and the next couple of weeks are a mixed bag. There’s a bit of a wait for the real quality, but patience will pay off.

Right now, we’re in a quiet patch. No surf worth grabbing a board for until Sunday, August 2nd. The wait is short, though.

Sunday morning, August 2nd, is where it starts. Thirroul picks up a 5ft SE groundswell with a 12-second period. The energy is solid (800). NW wind is blowing cross-offshore, keeping it clean. The water temp is about average for this time of year. This is the standout of the first week. The break is a beach and reef setup, so that long-period SE swell will wrap in nicely, offering some clean lines. Crowds are possible here, so don't expect to have it to yourself.

Sunday afternoon goes a bit average. The wind swings NE and the swell drops to 5ft, but it gets a cross-shore bump and the surf becomes more marginal.

Monday, August 3rd, the swell backs right off to 3ft, with NW offshore wind in the morning. It’s small and clean, but weak (169). Not worth a special trip.

Tuesday, August 4th, is a write-off. Swell drops to 0.7ft. Flat.

Wednesday, August 5th, sees a short-period S swell push in at 3ft, blowing cross-offshore, but it’s weak and ordinary. The afternoon picks up a little to 5ft, but still short period and messy.

Now, Thursday, August 6th, is a nice little window. Morning glassy conditions with a 5ft S swell, 8-second period, and clean. The energy is moderate (260). This is fun, small-wave surfing.

Friday, August 7th, the swell builds to 6ft in the morning, S direction, 9 seconds, but it’s cross-shore. By afternoon, it’s 7ft with a strong cross-on wind and 1006 energy, turning it into a choppy mess.

Saturday, August 8th, the swell hangs around 6ft, but the wind is cross-shore and the quality is poor. Not your day.

Sunday, August 9th, the swell drops to 4ft with a N cross-off in the morning. Clean but small. The afternoon gets ruined by a strong NE wind.

Monday, August 10th, is another near-flat day with tiny swell.

Tuesday, August 11th, now we’re talking. Morning offshore NW wind, 4ft ESE swell with an 11-second period. The energy is solid (371). The afternoon goes glassy. This is a beautiful, clean, long-period groundswell. It’s the second standout of the outlook. The longer period will make it peel nicely at the reefy sections.

Wednesday, August 12th, keeps it going. 5ft ESE swell, 10 seconds, with light NNW cross-off. Clean and fun. The energy is moderate (389).

Thursday, August 13th, things get serious. The swell jumps to 10ft from the S, but the wind is a fresh cross-shore, 30 km/h. This is big, powerful, and lumpy. The energy is strong (1635). This is for experts only, and even then, the wind is making it a battle.

Friday, August 14th, the swell peaks at 12ft from the SSE, with a massive 4622 energy. The wind is cross-shore, and the period is 10 seconds. This is a heavy, powerful, messy day. Only for the experienced, and you’ll be fighting the wind.

Saturday, August 15th, the swell backs off to 7ft, still cross-on. The quality is marginal.

Sunday, August 16th, a nice reset. Glassy morning, 4ft SSE swell, 10 seconds, with 396 energy. Clean and inviting. This is a good, gentle session.

Monday, August 17th, another glassy morning with 5ft S swell, 9 seconds, and 382 energy. A clean, fun way to start the week.

So, the real standouts are Sunday morning, August 2nd, and Tuesday, August 11th. Both offer clean, quality surf at Thirroul. The big swell in the middle of the second week is powerful but wind-shredded. Keep an eye on the glassy mornings towards the end.

Rusty.
