Narrabeen-Alley Rights Surf Forecast and Surf Report

Alright, grab your wettie and listen up. Rusty here with the look ahead for our local stretch.

It’s a bit of a slow grind to start, to be honest. We’ve got a few days of tiny, ordinary waves and a lot of onshore chop before things finally start to clean up. The water temp is sitting at 63°, which is about average for the time of year – no surprises there.

Friday 21st morning is about as good as it gets early on. Narrabeen-Alley Rights has a weak 3ft ENE swell pushing in, with a short, weak 6-second period and the combined energy is a low 69. The wind is a light offshore from the WNW though, so it’ll be clean. It won't be anything to write home about, but if you’re desperate for a paddle, that’s your window. By the afternoon the wind swings and it goes ordinary.

Saturday 22nd and Sunday 23rd are write-offs. Tiny, weak waves barely breaking, with poor conditions and cross-shore junk. We get a glassy session Sunday morning but the swell is a pathetic 2ft with a 4-second period – barely a ripple (energy 21). Don’t bother.

Monday 24th morning sees a slight bump to 3ft ENE, but still weak (73 energy) and short period. The wind is off from the NNE so it’s clean, but again, very ordinary.

We then hit a dry spell with nothing worthwhile on offer from the afternoon of the 24th right through to the morning of Wednesday 26th. Wednesday 26th morning finally sees the energy pick up a bit to 171, with a 4ft ENE swell. The period stretches to 8 seconds and it’s clean with a light WSW offshore, so it’s surfable, but still nothing special. The afternoon gets chopped up by a strong Southerly.

Thursday 27th and Friday 28th morning are messy with fresh cross-onshore winds. Friday morning is glassy with a light WSW breeze but the swell is back down to 3ft.

Saturday 29th stays clean with a light offshore, but it’s still weak – 3ft ENE at 7 seconds (155 energy).

Now, here’s the standout. Mark your calendar for Sunday 30th August morning. The swell jumps to a solid 5ft from the ESE, with a period of 8 seconds and the combined energy hits 316 – that’s a real injection of power. The wind is dead calm, glassy. That’s the best-looking session on the whole forecast. The only catch is that 5ft puts it on the edge of being a bit much for beginners. The afternoon gets ruined by an onshore Easterly, so get it early.

Monday 31stmorning is still surfable at 6ft ENE, with a clean offshore from the WSW, but the period is short at 7 seconds so it’ll be lumpy. Energy is high at 337, so there's push, but it’s not as clean as Sunday.

After that, the forecast gets messy again. A strong Southerly blows in on Tuesday 1st September making it a washout. A little clean-up on Wednesday 2nd September morning with 3ft ENE, but it's small.

Looking into the second week, Thursday 3rd September morning looks promising but less certain this far out. We’re looking at a 5ft NE swell, with a 7-second period, and a solid 416 energy reading. Winds are light offshore from the NNE, so conditions should be clean. That’s a good-sized, punchy wave for the experts and strong intermediates, but the onshore wind hits in the afternoon.

Overall, if you want the best wave, you’re looking at Sunday 30th morning. Get it while it’s glassy. For a second option, keep an eye on Thursday 3rd September morning.

Rusty.
