Thirroul Surf Forecast and Surf Report

G’day, it’s Rusty. Let’s be straight with you—this next stretch at Thirroul is going to test your patience. We’ve got a lot of ordinary, blown-out days ahead before things finally click into gear. There’s a long, frustrating run of small, choppy, onshore slop for most of the first week, so if you’re keen, pick your moments carefully. The real window of opportunity doesn’t show up until much later, so mark your calendar.

The opening days are grim. Thursday the 10th starts with a solid 8.2ft of south swell, but that’s about all it has going for it. There’s a moderate south breeze putting a real cross-chop on the surface, and the combined energy is strong, but it’s messy. By afternoon, it’s dropping and turning choppier. Honestly, it’s more of a battle than a surf. Friday and Saturday stay in that same rut—waist-high waves, lumpy cross-shore winds, and that short-period south-southeast swell just lacks any push. You’ll be scratching for a clean one. Sunday stays small and poor, and Monday the 14th is the closest thing to glassy, with a light north cross-off wind, but there’s almost nothing on offer, maybe ankle to knee-high.

The middle of the week gets awkward. Tuesday the 15th throws a bit of a spike—6.9ft of south-southeast swell in the afternoon—but it’s accompanied by a fresh cross-onshore wind and a lot of chop. Forget it. Wednesday is more of the same but smaller. Thursday the 17th has a clean, light north cross-off breeze, but the swell is gone again, 3.3ft at best. It’s a frustrating pattern. Friday the 18th is even smaller, with 1.6ft waves and a clean surface, but there’s just nothing to ride. That’s a week of waiting.

Now, here’s where it gets interesting. Saturday the 19th is the standout of the entire outlook. I’m talking about a proper pulse. The morning brings a solid 9.8ft of south swell, with a 10-second period and a light, clean north cross-off breeze. The combined energy is strong, and the surface is going to be clean. This is a big, powerful day for experienced surfers only. This isn’t for the faint-hearted or anyone still picking up their first boardshorts. It’s going to be thick and heavy at Thirroul’s beach and reef, a proper test. The afternoon eases off, but that morning session is the one.

Sunday the 20th offers a more manageable option. The south swell drops to 3.9ft, but we get a moderate northwest offshore wind in the morning. That’s clean, offshore, and the southeast swell has plenty of period. It’s not the raw power of Saturday, but it’s a much more user-friendly wave. Monday slips back into small, cross-shore slop. Tuesday the 22nd has a clean morning with a light north cross-off, but the swell is weak and short-period.

The final few days of this outlook are a mixed bag. Wednesday the 23rd has some size again—7.5ft in the morning, but with a short 7-second period. It’s a bit lumpy, but that afternoon it jumps back to 9.8ft, still with that short period, which can be a bit walled at a beach break, but the wind is offshore and clean. Thursday the 24th eases off, but the afternoon is a real diamond in the rough—4.9ft of south swell, 11 seconds, and glassy conditions. That’s a beautiful combo, but the rain might keep a few away. Then Friday the 25th finishes with a clean, light offshore and a residual 3.9ft south swell.

So, the call is simple: Saturday the 19th morning is the big dog, no arguments, but only for the experienced crew. The next best is Thursday the 24th afternoon when that glassy south swell rolls through. Everything else, you’re just paddling for scraps. Keep it salty.
