Thirroul Surf Forecast and Surf Report

G’day, I’m Rusty. Let’s have a look at what’s on the cards for Thirroul over the next couple of weeks.

Right off the bat, it’s a bit of a slow start. The first few days are pretty flat and underwhelming. We’ve got some small, weak pulses of south swell, but nothing that’s going to get the heart racing. The real action, the standout, doesn’t show up until the second week. Hang tight.

Monday 31st August – Thirroul is a bit of a letdown. Only 2.6ft of south swell, but it’s a short period 9 seconds and the wind is a cross-on from the NE at 9 mph. The water’s sitting at 63.5°, bang on average for this time of year, but the surf is just poor. Combined wave energy is weak at 172.

Tuesday 1st September – The morning cleans up with a light NNW breeze at 6 mph, feeling cross-off. Still only 2.6ft of south swell, but the period pushes to 11 seconds, giving it a bit more shape. The water’s still the same. It’s surfable, but very ordinary. The afternoon keeps the same size, with a north wind at 6 mph, and the energy bumps up to 253. It’s clean, but still small.

Wednesday 2nd September – A drop to 2ft of south swell, 10-second period. Mornings see a light offshore from the NW at 9 mph, making for clean little waves. Combined energy is a weak 115. Afternoon stays the same size with a WSW cross-off at 9 mph. Still very ordinary.

Thursday 3rd September – Swell drops further to 1.6ft, and by the afternoon it’s 1.3ft from the SSE. Energy is down to 85 and 68. The wind is offshore from the W at 12-16 mph, so it’s clean, but there’s barely a ripple to surf.

Friday 4th September – A tiny 2ft of south swell, 9-second period. Morning has a light NW cross-off at 6 mph, energy at 107. Afternoon goes to crap with a NE cross-shore at 16 mph, making it choppy. Poor.

Saturday 5th September – 1.6ft of south swell, 9-second period. Offshore from the NW at 16 mph in the morning, clean but tiny. Energy is a miserable 62. Afternoon is even smaller at 1.3ft. Not worth paddling out.

Sunday 6th September – Now this is something. The morning is glassy with zero wind, and we get a bump to 3.9ft of south swell, 9-second period. The energy jumps to 244. It’s clean, it’s glassy, and it’s the first real window of decent surf. The crowd factor is “sometimes,” so you might have a few locals out, but it’s worth it. This is the best of the early period.

Monday 7th September – A mixed bag. 3.9ft from the NE with a 6-second period – that’s short period junk. Morning wind is cross-off from the N at 9 mph, but the energy is 229. It’s marginal. The afternoon is 3ft from the ENE, still short period. Not great.

Tuesday 8th September – 3.9ft from the ENE, again with a short period of 7-9 seconds. Winds are cross or cross-on from the SSE. Energy is moderate at 230-304, but the quality is poor. Kite surfers might be having more fun here than paddle surfers with this setup.

Wednesday 9th September – Whoa, big change. The morning sees a massive jump to 14.8ft from the SSE, 10-second period. The combined energy is a powerful 4801. This is heavy, dangerous surf. The wind is light onshore from the SE at 6 mph. Only for experts. This is way too big for beginners. The afternoon stays at 14.8ft, 11-second period, with a light cross-on. Still huge.

Thursday 10th September – This is the true standout of the entire forecast. The morning is glassy, with 11.5ft of SE swell,
