The Lowdown

G’day, Rusty here, checkin’ in with a look at Shark Island (Cronulla) for the next couple of weeks. It’s a bit of a mixed bag, but there are a couple of windows that’ll get the blood pumpin’.

Kicking things off on Saturday, 29 August, we’ve got some solid energy in the water. The morning is the real standout – a clean 4ft SSE swell with a 10-second period rollin’ in. The combined swell energy is sittin’ at a solid 383 (moderate), and with a light 6 mph cross-offshore breeze from the SSW, it’s gonna be glassy and lined up. The water’s sitting at 63°, which is just about right for this time of year, nothin’ wild. This is advanced reef break territory, so it’s not for the faint-hearted, but if you’re up for it, that’s the session to hit. The afternoon sees the wind swing ESE at 6 mph, goin’ cross-shore, but the tide and conditions look a bit more marginal.

Sunday, 30 August, the swell drops back to 3ft from the south, and the morning’s clean with a light WNW cross-offshore breeze, but the energy’s way down to 220 (moderate). It’s surfable, but only just. The afternoon gets messy with a 9 mph SE cross-shore and slight chop. Not worth paddlin’ out.

Monday, 31 August, through to Monday, 7 September, is a real dry spell. We’re talkin’ nearly a week of tiny, weak, or blown-out surf. The swell stays under 3ft most days, with periods around 8–10 seconds, and the wind’s mostly onshore or cross-shore from the north-east, which just ruins it. The combined energy drops as low as 23 (weak) on the 5th. Even the few clean moments with offshore or cross-offshore winds, like Wednesday afternoon and Thursday morning, have waves that are too small to get excited about – just 2ft to 2ft. It’s a tough stretch.

Now, here’s the one that’s got me talkin’ – Sunday, 6 September, the morning. The swell jumps up to 5ft from the south, period bumpin’ to 9 seconds, and the combined energy hits 320 (moderate). The wind is a light 9 mph from the WNW, cross-offshore, keepin’ it clean. This is a proper session for advanced crew, and it’s the best wave we’ll see in the first week. The afternoon’s back to rubbish with a NE onshore, so make it a dawn patrol.

Monday, 7 September, is a write-off – strong 28 mph WNW winds, even if they’re cross-offshore, the swell’s only 3ft from the ENE with a crap 8-second period. Energy’s 183 (moderate), but it’s not worth it in that wind.

Tuesday, 8 September, sees the swell pick up to 5ft from the south by the afternoon, period 8 seconds, and energy jumps to 416 (moderate). But the wind is howlin’ at 25 mph from the SSW, cross-offshore, which makes it clean but gnarly. This is a big, powerful wave for experts only, and even then, it’s gonna be a battle.

Wednesday, 9 September, is the big one for the forecast. The morning brings a solid 7ft S swell, period 9 seconds, and the combined energy is a thumpin’ 700 (strong). Wind is 16 mph from the south, cross-offshore, so it’s clean. This is serious – over 8ft, it’s expert territory, and even at 7ft it’s a handful for anyone but the most experienced. The afternoon holds similar size, 7ft from the SSE, with a lighter 9 mph breeze. This is the standout of the whole outlook, but you’ve gotta be on your game.

From Thursday, 10 September, onwards, the swell drops back into the 2ft to 4ft range, with periods mostly short (8 seconds) and winds that are either light cross-shore or onshore from the north-east. The energy stays moderate, but the quality’s just not there. Sunday, 13 September, has a 4ft south swell with a 8-second period, and the energy is 340 (moderate), but the wind is a light cross-shore, and it’s only rated as marginal. It’s a tease, but not the real deal.

So, if you’re lookin’ for the best, it’s Saturday morning, 29 August, for a clean, fun size, or the big Sunday, 6 September, morning. But the true standout is Wednesday, 9 September – that 7ft south swell with clean winds is the one to circle, but only if you’ve got the skills for it. The rest of the 16 days is mostly a battle with small or blown-out waves. Stay patient, and keep an eye on the sky.

Rusty.
