Thirroul Surf Forecast and Surf Report

Alright, Rusty here. Let’s break down what’s coming down the line for us.

Straight up, the next two weeks aren’t going to set the world on fire, but there are a couple of clean, glassy windows that will make it worth schlepping down to the beach. The first week has some tricky conditions, but towards the end and into the second week, we get a couple of real gems.

We kick off on Friday, the 4th of September. The morning looks okay with a 3ft swell from the south, a period of 9 seconds, and a light cross-offshore wind. The combined energy is moderate (214). It’s clean, but nothing to write home about. By the afternoon, it drops off fast and the wind swings, so don’t plan your day around it.

Saturday the 5th is small and weak, with swell dropping to 2ft and 2ft. The wind is up, and it’s just not worth the paddle.

Sunday the 6th is a total write-off. The morning is tiny with a 2ft swell from the northeast, and the afternoon gets a bit of size (3ft) but it’s onshore and choppy.

Now, Monday the 7th – this is a standout. Early morning, the wind goes glassy, dead calm, and we’ve got a 4ft south swell wrapping in with moderate energy (214). It’s clean, it’s glassy, and it’s going to be fun. The only catch is it’s a beach and reef setup, and the swell period is 8 seconds, so it’s a bit shorter period, but that glassy wind will make it rideable. Crowds are possible here, so get in early.

Tuesday the 8th gets a bit chunky. The morning sees a 8ft south swell, but the wind is cross-onshore and the energy is strong (1338). That’s expert territory, and the conditions are marginal. The afternoon is a bit smaller at 4ft, but still onshore. Not the best for a paddle.

Wednesday the 9th and Thursday the 10th are messy. Thursday is particularly nasty with an 8ft south swell and strong onshore winds, energy hitting 1872 and 3054. That’s a lot of juice, but it’s going to be a washing machine. For the experienced, maybe a look, but it’s more of a kite-surfing setup than a clean paddle session.

Friday the 11th is still big and lumpy, with a 7ft south swell in the morning. The wind is cross-shore, so it’s not completely blown out, but it’s not clean.

Saturday the 12th of September – this is the real highlight. Morning session, we get glassy conditions again. A 4ft swell from the south-southeast, period of 11 seconds, and the energy is moderate (437). The wind is dead calm, glass. That’s a proper groundswell, and it’s going to be clean, lined up, and fun. The longer period (11 seconds) means better shape and more energy between sets. This is the session to aim for.

Sunday the 13th and Monday the 14th are small and weak again, with swell dropping below 3ft. Not much to get excited about.

Tuesday the 15th of September, the morning looks promising again. A 4ft swell from the south with a clean offshore wind from the west-northwest. The energy is moderate (274). That’s a clean, offshore morning with some size. The period is 8 seconds, so not a long-period groundswell, but it’ll be fun and hollow.

The rest of the second week, from Wednesday the 16th onward, is a bit of a fade. The swell sticks around 3ft to 3ft, but the wind gets up and by Thursday the 17th and Friday the 18th, it’s a full-on onshore gale. Strong breeze and messy conditions. Energy is moderate to strong (647-771) but it’s all wind and chop. Not worth it.

So, to wrap it up: Monday the 7th and Saturday the 12th are your best windows. Both have glassy mornings, clean surf, and enough swell to get some proper waves. The 12th has the edge with a longer period swell (11 seconds) and moderate energy (437). If you’ve got a free morning, that’s the one.

The water temperature is about average for this time of year, so no need to dig out the thickest rubber just yet.

Stay stoked, and I’ll see you out there.

Rusty.
