The Lowdown
Alright, this is Rusty, your local surf reporter, and I’m lookin’ at the next 16 days for our stretch of coast. Let’s get into it.
Right off the bat, we’ve got a slow start. Friday, July 31st, is a total write-off—tiny, messy, choppy. You’re better off waxin’ your board or just watchin’ the horizon. Surf doesn’t even start to show its face until Saturday, August 1st.
The standout window is Saturday morning, August 1st, through Sunday morning, August 2nd, at Narrabeen-Alley Rights. This is a beach/sandbar setup, exposed to the swell, and it’s an advanced wave. It’s very consistent, so it’ll be pumping. The water temp is about 64°, which is pretty normal for this time of year, nothin’ out of the ordinary.
On Saturday morning, August 1st, we get a solid 5ft swell from the SSE with a period of 9 seconds – that’s a nice, punchy groundswell. The combined energy is moderate (450). The wind is light and cross-offshore from the WSW, so those waves are gonna be clean. Saturday afternoon, August 1st, goes glassy from the NE – that’s the perfect window for the afternoon session. The swell drops a tiny bit to 5ft, but the energy is still strong (416). It’s going to be absolutely beautiful out there.
Then Sunday morning, August 2nd, is the real gem. The swell holds at 5ft from the SSE, but the period jumps to 13 seconds – that’s a long-period groundswell. The energy is massive (999). The wind is a light offshore from the N, making it clean. For a beach/sandbar like this, that long period can make it a bit straight, but the quality of the energy and the offshore wind should make for some proper, lined-up waves. Crowds are often here, so expect a few heads in the water, but it’s worth it.
Sunday afternoon, August 2nd, gets a bit messy with a cross-shore, so it’s not as good. After that, the surf drops off hard. Monday, August 3rd, has a small 3ft morning, but it’s a drop-off. From Tuesday, August 4th, all the way through to Tuesday, August 11th, it’s a long, flat spell. There’s a few tiny swells, but they’re all under 2ft and not worth paddlin’ for. It’s a real dead zone.
We see a bit of a pulse again on Wednesday, August 12th, with a 3ft swell from the E, but the wind is strong and the conditions are just marginal. The next few days, up to Friday, August 15th, are all small, messy, or cross-shore. The swell tries to bump up to 4ft on Friday, August 14th, from the SSE, but the wind is fresh and it’s just not clean.
So, overall, the best on offer is the Saturday morning, August 1st, through Sunday morning, August 2nd, at Narrabeen-Alley Rights. With the glassy conditions on Saturday afternoon and the long-period energy on Sunday morning, that’s your call. The run from Tuesday, August 4th, to Tuesday, August 11th, is a dead loss of about 8 days – a real disappointment. The long-range stuff around August 12th to 15th is a bit of a tease, but nothin’ you’d set your alarm for.
Rusty out.
