The Lowdown
G’day, Rusty here. Look, I’ll be straight with you – this Narrabeen-Alley Rights stretch is in a bit of a funk for the next week or so. We’ve got a long dry spell before anything really worth paddling out for shows up. The water temp is sitting at 64°F – pretty much average for this time of year, so no surprises there.
The first real glimmer comes on Sunday morning, 30 August. It’s small – only 2ft from the SE with a 10-second period – but the wind is light offshore from the NW. That means clean, glassy lines. The combined wave energy is sitting at 123 (moderate energy), so there’s a little bit of push. It’s not a standout, just a “surfable but ordinary” kind of session. Still, it’s the best on offer for a while.
After that, we go into a real quiet patch. From Monday 31 August right through to Saturday 12 September, the swell drops right off – mostly 1ft to 1ft, and often with short periods under 8 seconds. The wind is all over the place but mostly cross or cross-off, so the waves are just too weak to get excited about. There’s a brief moment on Thursday 3 September afternoon where it goes glassy – 1ft from the ENE – but there’s no energy (24 combined energy). You’d be bobbing around for nothing.
Now, the standout. Sunday 13 September morning. That’s the one to circle on the calendar. We’ve got 3ft of SSE groundswell rolling in with a 10-second period, and the combined energy jumps to 210 (moderate-to-strong energy). The wind is light from the NNW, so it’s cross-off and clean. The swell direction is SSE, which is right in the sweet spot for this break’s optimum (ENE). It’s a beach/sandbar setup, very consistent, and it’s an advanced wave – so if you’ve got the skills, this is the session. Crowds are often around here, so expect company. That Sunday morning is the best we’ve got.
The rest of that Sunday afternoon gets a bit chopped with a cross-shore NE breeze. So really, Sunday 13 September morning is your window. It’s a long way off, but it looks promising.
Rusty.
