The Lowdown
G’day, Rusty here. Look, I’m not gonna sugarcoat it – the next week or so is a real struggle. Shark Island (Cronulla) is looking pretty flat and messy for days, but we do have a couple of bright spots to hang onto.
The water’s sitting around 62°, which is a bit colder than normal for this time of year, so you’ll want a decent steamer.
We’ve got a long stretch of poor conditions from Saturday the 22nd right through to Wednesday the 26th. Tiny waves, onshore winds, and just nothing to get excited about. Thursday the 27th morning shows a bit of life with a 5ft south swell, period of 8 seconds, and a clean cross-offshore breeze from the south. The combined energy is moderate (301), so there’s some push there, but it’s not a standout. Friday the 28th morning is clean with a light west wind, but the swell is only 3ft and from the south – small and weak.
Now, the real hope comes in on Saturday the 5th of September. That afternoon, we’ve got a clean, light southeasterly breeze and a 2ft south swell with a very long period of 19 seconds. The combined energy jumps right up to 451 (strong). That’s a groundswell with serious energy behind it, so even though the height is small, the lines should be long and powerful. It’s a reef break, so that long period will hold up nicely. Keep in mind, this is over a week away, so lock it in with a bit of caution.
Then Sunday the 6th of September morning builds on it. A 5ft south-southeast swell, period of 8 seconds, clean offshore winds from the south-southeast, and combined energy of 364 (moderate). That’s the pick of the whole forecast. The swell is a solid size, the wind is clean, and the break is fairly exposed to that direction. This is a true standout for the advanced surfers – anything over 5ft can be a handful, so it’s not for the beginners.
The best of the best is Sunday the 6th morning. Get on it. The crowds are ‘sometimes’ there, so you might have a few others in the water, but with that clean, offshore wind and a solid south swell, it’s worth the paddle.
Rusty.
