The Lowdown
G’day, Rusty here. Let’s be straight with it – the next couple of weeks at Narrabeen-Alley Rights look pretty grim for a proper paddle session. The wind and the swell just aren’t playing ball most days.
We’ve got a long gap with no real redeeming quality until we hit the end of the month. Wednesday the 26th and Thursday the 27th are a write-off – messy cross-onshore winds, lumpy and choppy, with weak, short-period swell barely pushing 3 ft. The combined energy is a paltry 167 and 62, respectively. Water temp is sitting at 63°, about a degree cooler than average, so nothing wild.
Friday the 28th of August is the only time the ocean shows a bit of interest. The morning session offers the best hope we’ve got. A 6 ft swell from the SSE with a period of 11 seconds rolls in – that’s a nice, long-period groundswell. The combined energy jumps right up to 699, which is proper moderate energy. The wind is light and cross-shore, so it’ll be a bit lumpy but not totally wrecked. This is an advanced break, and the swell is over 5 ft, so it’s a bit chunky for the groms. It’s a beach/sandbar setup, so the long period might make it run a bit straight, but it should still offer some grunt. The crowds are often here, so expect company. The swell is coming from the SSE, which is a fair way off the optimum ENE direction, but the size and power make up for it a little.
From Friday afternoon onward, it drops right off. The rest of the 16-day window is full of tiny, weak swell (under 2 ft) and, for the most part, clean but completely gutless conditions. A few mornings have glassy or clean offshore winds, but without any real push, it’s just a lake. The combined energy dips down into the teens and twenties – that’s barely a ripple. If you’re desperate for a float, you could get a wet suit wet, but don’t expect a wave.
So, if you're keen, set your alarm for the early session on Friday, August 28th. That’s the only real standout in a very quiet stretch.
Rusty.
