Thirroul Surf Forecast and Surf Report

G’day, Rusty here, lookin’ at the charts for Thirroul. We’ve got a bit of a slow start, but there’s some promise further out if you’re patient.

The first few days are a bit of a write-off, with a lot of marginal surf and onshore or cross-shore winds messing things up. Thursday the 30th of July kicks off with a 5-foot southerly swell at 9 seconds, but it’s cross-shore and the energy is weak (340). The afternoon gets a bit bigger at 5 feet, but the wind swings cross-onshore and it’s choppy. Friday the 31st of July is similar – 6 feet in the morning with cross-shore wind, but it’s a messy 10-second period. The afternoon picks up to 7 feet, but that cross-onshore breeze at 20 km/h is gonna make it a lumpy burger.

Saturday the 1st of August stays in the doldrums. Morning is 5 feet with a cross-shore breeze. The afternoon, though, gets a glimmer – a 5-foot southerly swell, but the wind goes glassy. That’s a rare clean moment, but the energy is still weak (400) and the waves are short-period. It’ll be small, clean, and fun for a grovel.

The real standout pops up on Sunday the 2nd of August. Thirroul is a beach-and-reef set-up, exposed to the south-east. The swell is 5 feet from the SE, with a 12-second period – that’s a proper groundswell with some grunt. The wind is a light cross-offshore from the NNW at 15 km/h, which will keep the faces clean. The combined energy is moderate (725). This is your best bet for the first week. It’s not huge, but it’ll be well-shaped, especially for a point or reef, and the offshore wind is a major plus. Crowds are possible, so get in early.

Sunday afternoon sees the wind swing cross-shore and the swell drop, and things go flat from Monday the 3rd of August through Wednesday the 5th of August, with barely a ripple. There’s a gap of about three days of poor to no surf.

Thursday the 6th of August brings a 7-foot SSE swell, but it’s cross-shore and the wind is building, so it’s average. Friday the 7th and Saturday the 8th are a write-off with strong winds – 25 to 30 km/h winds making it a lumpy mess, better suited for kite surfing.

Monday the 10th of August has a surprise: a 4-foot NE swell with a short 7-second period, but the wind is glassy early. The energy is still weak (288), but for a small, clean session, it’s a sneaky option.

Then we get into the second week and things start to look more promising. Tuesday the 11th of August: 5 feet from the ESE at 11 seconds, with a clean cross-offshore wind. The energy is moderate (521). Wednesday the 12th of August is the standout of the second week. Thirroul sees a 6-foot ESE swell with an 11-second period, and the morning has a clean cross-offshore wind from the WSW at 15 km/h. The combined energy is solid (808), and the forecast is for very good surf conditions. This is a long-range call, so it’s promising but not locked in. The swell direction matches the optimum from the south-east, so it’ll work well on the reef.

Thursday the 13th of August packs a punch: 8 feet from the S at 9 seconds, but the wind is cross-shore, making it a bit of a handful. The energy is strong (1896), but it’s on the cusp of being too big for beginners. The afternoon sees 10 feet, which is only for experts. Friday the 14th of August eases off to 7 feet, with a clean cross-offshore wind, but the period is short at 8 seconds.

Overall, the best on offer is Sunday the 2nd of August for the clean, long-period SE groundswell, and Wednesday the 12th of August for the bigger, clean ESE swell. Don’t get too excited about the first few days – it’s a waiting game.

Rusty.
