Thirroul Surf Forecast and Surf Report

Alright, Rusty here. Let’s have a look at what’s coming down the line for the next couple of weeks.

Alright, the outlook for Thirroul is a bit of a mixed bag, but there are a couple of windows that’ll get your blood pumping. The next week or so has some clean, solid energy, but it’s not a straight run of winners. Get ready to be picky.

Overall, the water temp is sitting right around average for this time of year at 64°, so no surprises there.

Let’s kick things off this Sunday morning, August 23rd. It’s not huge, but it’s clean. We’ve got 4ft of S swell ticking over at 8 seconds, with a light NNW cross-off breeze. The energy is moderate (215), and the conditions are clean. It’s a solid start to the weekend if you’re keen for a morning paddle.

Monday the 24th is a step down. The swell drops to 2ft in the morning, and while the wind is light, it’s not doing us any favours with that N cross-off. It’s surfable, but very ordinary. The afternoon is a write-off with a 12 mph NE cross-shore chop.

Tuesday the 25th is interesting. The morning brings a 4ft swell from the NE with a short period of 6 seconds. That’s a bit of a junky period, but with a light NW cross-off breeze, it’ll be clean. The energy is moderate (251). It’s worth a look, but the shape won’t be world-class.

Wednesday the 26th is a day to stay home. The morning is chopped out with a 12 mph S cross-shore, and the afternoon brings a cross-on breeze that’s just messy.

Now, here’s your first standout. Thursday morning, August 27th. This is the one. Waves hit 5ft from the S at 9 seconds, with a glassy NNW breeze of only 3 mph. The energy is strong (424). It’s clean, it’s punchy, and it’s calling your name. The morning is the golden window here – the afternoon turns into a cross-on mess.

Friday morning, August 28th is another very good option. The swell drops to 3ft, but it’s from the SSE with a longer 11-second period, and a super clean SW cross-off breeze. The energy is moderate (323) but the quality will be there. This is a long-period groundswell, so it’ll have better shape and more push, but the sets will be a bit more spaced out. Perfect for a point break setup.

Saturday, August 29th is a full day of winners. The morning has 5ft of S swell with a NW offshore wind – clean and lined up. The energy is strong (427). The afternoon holds up with 4ft of S swell and a WSW cross-off. You can surf from dawn ‘til dusk.

After that, things get a bit more complicated. Sunday the 30th has size (6ft in the morning, rising energy 1039) but the wind is a cross-on from the S, making it choppy. The afternoon has a very long 16-second period from the SSE with massive energy (1089), but it’s onshore. For a beach and reef setup, that long period could make it a bit too straight and tricky. It’s more of a kite-surfing day, to be honest.

Monday the 31st is a morning mission – 5ft SSE swell, 11 seconds, and a clean NNW cross-off. The energy is strong (505). Worth the early alarm.

The first week of September starts to fade. Tuesday the 1st has clean, offshore conditions but the swell drops to under 3ft. It’s surfable, but not a standout. From Wednesday the 2nd onwards, the surf gets very small and ordinary, with most days struggling to see anything over 2ft and energy dropping into the weak double digits. There’s a gap of several days with no real recommended surf from about the 2nd through the 7th. The 7th has a brief spike of 5ft from the NE in the afternoon, but with a strong 16 mph offshore wind, it’s clean but the period is a poor 5 seconds – more of a wind bump than a proper swell.

So, if you’re picking shots, make Thursday the 27th and Saturday the 29th your targets. The rest of the run is a waiting game.

Rusty.
