Thirroul Surf Forecast and Surf Report

Alright, this is Rusty. Let’s have a look at what’s coming up for Thirroul.

First thing you need to know – the water temp is sitting at 64°, which is right around average for this time of year. No surprises there.

Right now, we’re looking at a bit of a slow start. The first surf worth mentioning is Saturday morning, the 29th of August. It’s small, around 4ft from the SSE, with a period of 9 seconds. The wind is cross-onal from the SSE at 3 mph, so it’s a little messy. Combined energy is weak (358). It’s surfable but nothing to write home about. Saturday afternoon is even smaller with onshore wind, so don’t bother.

Sunday the 30th is the first real standout. Early morning you’ll find 3ft of S swell, period 9 seconds, and the wind is *glass* – dead calm. That’s going to be clean as a whistle. Energy is light (222), but for a small wave session, it’ll be fun. Afternoon turns onshore and drops off, so get out early.

Monday the 31st through to Wednesday the 2nd of September is all small stuff: 2ft to 3ft, mostly from the south, with light cross-offshore winds in the mornings. It’s clean but tiny. Combined energy stays under 200. Not worth planning your day around, but if you’re desperate for a paddle, the mornings are your best bet.

Thursday the 3rd of September morning sees a 1ft SSE swell with a 12 mph WNW offshore wind. That’s clean but barely breaking. Energy is very low (76). Friday the 4th and Saturday the 5th are similar – small, clean mornings but nothing with any punch.

Now, Sunday the 6th of September morning – 3ft of S swell, period only 7 seconds, but glassy wind again. It’s weak (82 energy), but if you want a glassy, small-wave session, it’s there.

Here’s the big one. Monday the 7th of September morning – swell jumps to 5ft from the south, period 9 seconds, and we’ve got a 19 mph offshore from the west. That’s clean, but the wind is strong. Combined energy is moderate (301). Tuesday the 8th is even bigger: 5ft in the morning and 6ft in the afternoon from the south, with a 12-second period. That afternoon swell has *very strong* energy (1116). The wind is cross-offshore, but at 25 mph, it’s going to be a battle to paddle into. This is expert territory. The 6ft is over 5ft, so beginners beware.

Wednesday the 9th and Thursday the 10th of September – solid 6ft to 7ft south swell, periods 11-12 seconds, but the wind is cross or onshore, making it choppy. Energy is very strong (852-1124). These are expert-only waves if you can handle the wind.

Then Friday the 11th of September – a nice reset. Morning brings 4ft of SE groundswell, period 12 seconds, with glassy wind. Energy is moderate (402). This is a proper standout for the intermediate crew. Clean, long-period lines. The afternoon goes onshore, so again, early session.

After that, it’s back to small stuff through to the 13th of September: 1ft to 2ft, clean mornings but very weak energy.

Overall, the best on offer is Sunday morning the 30th of August for the glassy, clean small waves, and Friday morning the 11th of September for the best mix of size, period, and glassy conditions. The 7th to 9th of September has real size but strong winds, so only for the experienced crew.

Rusty out.
