Thirroul Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.

We’re in for a pretty quiet run, to be honest. There’s a gap of surfable days right at the start before we get into anything worthwhile. The first real action is looking at Sunday morning, the 30th of August. That’s our first little standout. Thirroul will be tiny, with only 3 ft of swell from the S, but the wind goes glassy, dead calm. That’s a major positive. It’ll be clean as a whistle, but don’t expect much push. The combined energy of all swells directed here is weak (211). It’s a morning session for the longboard or a log, just to get wet.

Then we have a decent stretch of small, clean peaks from Monday morning through to Tuesday morning. Monday the 31st sees 3 ft from the S with a light cross-off wind from the NNW. Clean, but very ordinary. On Tuesday the 1st of September, the swell drops to 3 ft again, but the period stretches out to 11 seconds. That’s a longer period groundswell, so the waves will have more shape, more energy (214), and longer waits between sets. That’s actually a nice trade-off for a small day. Light cross-off NNW wind again. Worth a paddle.

The real standout, though, is shaping up for Sunday the 6th of September. The morning shows 4 ft of S swell building with a clean offshore wind from the WNW. The combined energy bumps up to a moderate 201. Then the afternoon gets even better: 4 ft from the S, period hitting 11 seconds, and the combined energy jumps to a strong 318. Wind goes light and variable, almost glassy. That Sunday afternoon is the pick of the lot—clean, solid energy, and a proper long-period swell. Expect better shaped waves and longer lulls, which makes paddling back out easier.

A word of caution: On Tuesday the 8th of September, the swell jumps to 10 ft from the SSW. That’s way too big for beginners, and with a fresh cross-shore wind and lumpy chop, that’s for experts only, if anyone. The combined energy is a massive 1980, which is very strong. That whole Tuesday and Wednesday (the 9th) look messy and big. Not a paddle surfer’s dream.

The water temperature is sitting at 64°F with a small anomaly of 0.9°F, so it’s about average for this time of year at Thirroul. No surprises there.

So, to wrap it up: the best bet is Sunday morning the 30th for a glassy, tiny clean-up, and the absolute standout is Sunday the 6th of September, afternoon session. The long-range stuff for the 12th and 13th looks promising but less certain, with clean conditions and moderate energy. Keep an eye on it.

Rusty.
