Thirroul Surf Forecast and Surf Report

Alright, Rusty here again. Let’s break down what’s happening around Thirroul for the next couple of weeks.

It’s a slow start, to be honest. The first few days are pretty grim, so don’t bother paddling out until things clean up. Save your energy for later in the week.

Monday the 7th of September is the first real window. A clean morning with a light north wind and a 1.4m SSE swell. The combined wave energy is moderate at 301, and the light air will keep the surface smooth. It’s not big, but it’s a decent start to the week.

Tuesday the 8th is a bit mixed. A 2.1m SSE swell in the morning with moderate energy at 630, but the wind is cross-shore and the forecast calls it marginal. The afternoon drops to 1.8m with light cross-onshore wind, so still a little messy.

Wednesday the 9th is a write-off. Strong winds from the SSW and S at 30 km/h make for lumpy, poor surf. Leave the board at home.

Thursday the 10th brings a big jump in size, but it’s not for everyone. A 3.0m S swell in the morning with very strong wave energy (2754), but the wind is cross-onshore and choppy. This is expert-only territory. The afternoon drops to 2.5m, still big and messy.

Friday the 11th is a bit more manageable. A 1.8m SSE swell in the morning, light wind, and clean conditions. Energy is moderate at 673. It’s still flagged as marginal, but a dawn session could be worthwhile.

Saturday the 12th fades a little. The swell drops to 1.4m in the morning, but the wind is cross-onshore and gets choppy in the afternoon. Not the best.

Sunday the 13th and Monday the 14th are worth a look. Both mornings have clean conditions with light offshore winds from the NW. Swell is small, around 0.9m SSE, but it’s a longer period swell (11 seconds) which means better shaped waves. Energy is light to moderate, around 258 and 232. It’s small and clean, good for a longboard.

Now, here’s the standout. Tuesday the 15th of September. The morning brings a 1.3m S swell with light offshore winds and clean conditions, with moderate energy at 403. But the afternoon is where it’s at. The wind goes glassy, the swell bumps to 2.0m from the south, and the energy is moderate at 545. The forecast calls for very good surf conditions. This is the pick of the period. Get out there for the afternoon.

From Wednesday the 16th onwards, the surf starts to taper off. The swell drops back to 1.4m and smaller, with more onshore winds and poor conditions through the end of the week. By the weekend of the 19th and 20th, we’re looking at small, clean but very ordinary surf in the 0.6m to 0.9m range. The 21st of September has a tiny 0.5m S swell with weak energy at 49. It fades out quietly.

So, to sum it up: Monday the 7th is a clean start, but the real standout is Tuesday the 15th, especially the afternoon glass-off with 2.0m swell. After that, it gets smaller and quieter. Make the most of that Tuesday.

Rusty.
