The Lowdown
Alright folks, Rusty here. It’s been dead quiet, so let’s get into it. This 16-day stretch starts off boring, but there’s some hope later if you can hang on.
Right now, and for almost a week and a half, there’s nothing. The first real shot at a wave doesn’t come until Saturday September 12th, and even that’s touch and go. Water temp at Narrabeen-Alley Rights is 64°F, which is about normal for this time of year.
Wednesday September 2nd has a tiny 1ft ENE swell with weak energy (53), but the morning has a clean NW offshore at 12 mph – it’s ridable but barely. That flash is gone by afternoon.
Then a long dry spell: from Wednesday afternoon all the way to Saturday the 12th, it’s an eight-day stretch with no surf. Swells stay under 2ft, periods are short (5-10 seconds), and winds are mostly cross or onshore. Energy readings are mostly under 60. Thursday the 3rd and Friday the 4th have glassy mornings, but with only 1ft waves, it’s not worth the paddle.
Saturday September 12th finally shows a pulse: a 5ft NE swell with a 7-second period, and energy jumps to 425 (moderate). The wind is a light cross-off from the NNE at 9 mph, so it’ll be clean. That’s your standout – a solid clean window, but it’s a beach/sandbar and the short period means it’ll be a bit lumpy. Crowds are often a problem here.
Sunday the 13th fades again – 3ft ENE, but the morning has a gentle offshore from the NW at 9 mph (86 energy). Clean, but average.
From Monday the 14th into Tuesday the 15th, onshore winds return with 3-4ft ENE swell and energy in the 200s. Skip it.
The real payoff is Wednesday September 16th and Thursday September 17th. Wednesday morning delivers a 6ft E swell with an 8-second period, strong energy (468), and a cross-off breeze from the W at 9 mph. That’s the best of the lot – clean, solid, and the direction lines up with the spot’s optimum (ENE). Over 5ft, so it’s for experts only. Thursday morning holds at 5ft ENE with a light N wind (6 mph) and 364 energy – another clean one.
Long-range: Wednesday the 16th and Thursday the 17th mornings are the gems. Not a sure thing yet, but if you’re patient, that’s your window.
Bottom line: nothing worth paddling for until the 12th, and even that’s marginal. The 16th and 17th are the real deals.
Rusty.
