Cunns Surf Forecast and Surf Report

G’day, Rusty here. Alright, let’s have a proper look at what’s on the cards for Cunns over the next couple of weeks. This is a solid reef break, exposed to the south-west, but it’s inconsistent – so when it fires, you gotta be on it. The water temp is about average for this time of year, nothing wild there.

We’ve got a bit of a slow start. Wednesday morning the 16th sees a clean 6ft southwest swell rolling in, but it’s blowing a fresh 19 mph offshore from the east-southeast. The wave energy is strong, sitting at 1246, so there’s plenty of push. But that stiff breeze will keep it clean for the experienced crew. It’s a bit of a handful for your average punter though. That afternoon the wind swings cross-off and the swell drops slightly to 5ft – still clean, but the score drops back a notch.

Thursday the 17th is cleaner in the morning with a moderate cross-off breeze and a 5ft southwest swell, but the energy drops to 742. Still a fun wave for those who know the reef. Thursday arvo gets interesting – a light 6 mph offshore and a 4ft swell with 14-second period. It’s clean, glassy conditions for a mellow session, but don’t expect any barrels.

Friday the 18th and Saturday the 19th are write-offs. The swell drops below 3ft, wind turns messy, and the whole setup goes lumpy. Poor conditions with energy down in the 100–300 range. Not worth paddling out.

Sunday the 20th has a tiny 3ft swell and a light cross-shore breeze in the morning – marginal at best. The period is a long 16 seconds, which at a reef like Cunns could still offer a few tricky lines, but it’s thin.

Now, here’s where it starts to get interesting. Monday the 21st morning: clean, light offshore, and a 4ft southwest swell with a 13-second period. Energy is moderate at 488, but the consistency is the issue – still, it looks fun for a dawny.

The standout window is Tuesday the 22nd. Morning delivers a clean 5ft southwest swell with a 15-second period, gentle offshore from the east at 9 mph. The energy is strong at 1123. This is excellent surf for experienced surfers – the reef will groom that long-period groundswell into proper lines. Crowds are likely though, as it’s a known spot. Tuesday afternoon stays clean but the magic fades slightly.

Wednesday the 23rd morning is still decent – 4ft southwest swell, moderate offshore, energy at 686. It’s very good but not quite the standout. The afternoon gets blown out by a strong breeze.

Thursday the 24th and Friday the 25th are small and marginal – 4ft dropping to 3ft, clean but not much juice. Saturday the 26th sees a big jump in swell – 4ft in the morning but with a nasty 22 mph cross-on from the north-west that ruins it. The afternoon pumps up to 6ft with a 19-second period and energy at 2746, but it’s cross-shore and lumpy – more of a kite-surfing show than a paddle session.

Sunday the 27th is also blown out with onshore and cross-on winds, big swell up to 7ft but messy.

Monday the 28th brings a clean 7ft southwest swell – that’s expert territory. It’s cross-off, moderate breeze, so it’ll be clean, but only for the brave. Energy is 2026 – very strong.

Tuesday the 29th morning is another gem – gentle offshore, 5ft southwest swell, very good conditions. Energy at 625.

The final standout is Wednesday the 30th of September morning. A clean 6ft southwest swell with an 18-second period, light offshore from the east-southeast at 6 mph. Excellent for experienced surfers, energy at 1842. This is proper groundswell – the reef will handle it beautifully. Thursday the 1st of October morning keeps the run going with a 5ft southwest swell, gentle offshore, and energy at 1336 – also excellent.

So overall, you’ve got two real standout windows: Tuesday the 22nd and Wednesday the 30th. Both offer clean, offshore conditions with strong, long-period swell. Crowds are likely at Cunns, so get in early. The breaks in between are mostly for the keen, but these two days are the ones to circle.

Rusty.
