Cunns Surf Forecast and Surf Report

Alright, Rusty here. Let’s chew the fat on what’s coming up for our local patch.

Alright, mate, it’s a bit of a mixed bag for the next couple of weeks. We’ve got pulses of solid, long-period groundswell from the southwest, but the wind ain’t always playing nice. This spot, Cunns, is a proper reef setup, so those long-period swells (17 seconds and beyond) will line up nicely here compared to a beachie, but it’s an inconsistent wave – you gotta be patient. A lot of the early days are cross or cross-onshore, which means chop and bump, so we’re waiting for the windows of cleaner conditions.

Sunday the 23rd is a write-off – we’ve got 5ft of long-period swell (17 seconds) but a stiff 25 km/h cross-shore wind from the NNE makes it a messy one. Moderate combined energy (1274) but not worth paddling out for. Monday 24th looks even worse in the afternoon with a fresh 35 km/h cross-shore wind from the SSW making it lumpy.

The first real glimmer comes on Wednesday the 26th afternoon. The wind drops to zero – glassy as a mirror. Swell is down to 3ft from the southwest, period a more modest 12 seconds, so combined energy is lower (385), but with clean conditions, it’ll be a fun, small session for a log or a fish. That glassy wind is a major positive.

Then we hit a standout. Sunday the 30th afternoon (August) is looking mint. The wind swings offshore from the southeast at 20 km/h, grooming a 4ft southwest swell with a period of 16 seconds. That’s a proper groundswell, a low tide special on the reef, and the combined energy is a solid moderate (1080). This is the pick of the first week – clean waves with some push. It won’t be overly crowded as it’s inconsistent, but fair warning, crowds are possible here.

Monday the 31st afternoon is another beauty – glassy again, with 5ft of swell (16 second period) and 1109 combined energy. The conditions will be clean and organized.

After the 31st, the wind turns ugly again with strong cross-onshore and onshore winds, making the first few days of September a write-off. The conditions don't turn around until Wednesday the 2nd afternoon, when a 20 km/h cross-offshore breeze from the south cleans up a 4ft, 15-second swell.

The real highlight of the whole forecast window lands on Friday the 4th of September morning. We get a light offshore breeze from the east at just 10 km/h, pairing with a clean 6ft swell from the southwest. The period is a solid 15 seconds, and the combined energy is a strong (1732). This is excellent surf for experienced surfers – the swell is over 5ft, so it’s a step up, but the offshore wind and long period will offer some proper walls on the reef. Keep in mind, this is two weeks out, so while it looks promising, it’s a long-range call.

The following days get blown out or too big, with a massive 8ft, 18-second swell from the west-southwest hitting Monday the 7th morning. That’s pushing 4839 combined energy – very strong. That’s for experts only, and with an onshore wind, it’ll be a heavy, unruly beast. Most likely a kite-surfing day unless you’re a seasoned charger.

So, to sum it up: the best windows are the afternoon of Sunday the 30th of August, and the morning of Friday the 4th of September. The 4th is the true standout if the forecast holds.

Rusty.
