The Lowdown

Alright, gather ‘round, crew. Rusty here with a look at what’s on the cards.

Alright, look, I’ll level with you. The next week and a half isn't exactly firing. We’ve got a long, drawn-out lull coming after a few sessions that look worthwhile. The standout window is Thursday the 27th of August right through to Monday the 1st of September, with a real highlight on Saturday the 29th. After that, we hit a pretty flat spell with nothing worth paddling out for until Wednesday the 9th of September, and even that is a long-shot call.

Let’s break it down. Tuesday the 25th and Wednesday the 26th? Give ‘em a miss. The swell is tiny, messy, and winds are all over the shop. We start seeing a pulse on the morning of Thursday the 27th. Shark Island (Cronulla) will have a building 6ft south swell, period around 9 seconds, with a light S cross-off breeze. The combined energy is moderate at 598. It’s a bit lumpy, but it’s a reef break, so the longer period swell from the south-east is going to groove up nicely. Crowds are a sometimes thing here, so you might get a few out.

Friday the 28th morning looks better again. That swell drops a touch to 5ft, but the direction swings to the SSE and the period stretches to 11 seconds, giving it some real grunt. Combined energy climbs to a solid 663. The wind goes offshore from the SW, and it’s light. That’s clean, lined-up reef waves. Honestly, Friday morning is a top pick.

But the absolute best of the run is Saturday morning the 29th of August. The swell holds at 6ft from the SSE with a 10-second period, and combined energy is strong at 740. The wind is virtually nothing—just a slight air from the SSW, making it glassy. This is the session. If you can get out there early, it’ll be as good as it gets. The afternoon gets a bit sloppy though, so make the most of the morning.

Sunday the 30th and Monday the 31st are still rideable. Sunday morning has a clean 4ft S swell, but Monday morning is the real sleeper: a glassy 4ft S swell with no wind. That’s a sneaky good session with the reef working its magic.

From Tuesday the 1st of September onwards, the energy drops out. We go from marginal on Tuesday to tiny by Wednesday the 2nd, with combined energy falling under 100. It stays poor and small right through to Tuesday the 8th of September. Honestly, it’s a real dry spell.

The only flicker of hope is the very last entry: Wednesday morning the 9th of September. We’ve got a 5ft SSE swell with a short 8-second period, combined energy of 329, and a clean offshore wind from the SSW. It’s a good sign, but it’s a long way off, so keep an eye on it.

To wrap it up: get out there on Friday the 28th morning and Saturday the 29th morning for the cleanest, punchiest waves. Monday the 31st morning is a dark horse for a glassy session. The rest is mostly stuff all or a waiting game.

Stay salty.

Rusty.
