Narrabeen-Alley Rights Surf Forecast and Surf Report

G’day, I’m Rusty.

Alright, let’s talk about the surf at Narrabeen-Alley Rights. Friday morning, 28 August, is the real standout across this whole 16-day window. The water temp is sitting at 64°, which is pretty much normal for this time of year, so nothing weird going on there.

Kicking off Thursday morning, 27 August, it’s small and choppy with a cross-on southerly breeze and a weak 2ft ENE swell, period around 8 seconds. Combined energy is a paltry 54 – just not worth paddling out for. Thursday afternoon is even smaller and onshore. Not happening.

Then Friday morning, 28 August, is where it gets good. We’ve got a solid 6ft swell coming from the SSE with a nice 11-second period, and the combined energy is a solid 669 (moderate wave energy). The wind is light WSW at 5 km/h, coming cross-offshore, so the face is clean. This is a proper groundswell pulse, and at this size, it’s pushing into the advanced range, so beginners should sit this one out. The long period (11 seconds) means the waves will have decent shape and energy, but the sets will be spaced out a bit. It’s a beach/sandbar setup, so that long period can make ‘em a bit straight, but with the clean conditions, it’ll be well worth it. Crowds are often here, so expect some company. Best session of the whole forecast.

Friday afternoon, the wind swings southeasterly and picks up, making it choppy again. The swell drops to 5ft, but the cross-on wind ruins it.

Saturday morning, 29 August, has a 4ft SSE swell, but the wind is cross-shore, so the surface is a bit messy. Saturday afternoon is small and cross-on. Not great.

Sunday morning, 30 August, has a tiny 2ft swell with clean cross-off wind, but the combined energy is only 124 – it’s surfable but very ordinary. Sunday afternoon is even smaller.

Monday morning, 31 August, is glassy but with only 1.0ft on offer. Nothing to get excited about. The rest of the first week and into the second week stays tiny, with small swells and mostly clean but weak conditions. On Tuesday afternoon, 1 September, there’s a 3ft NE swell with a short 5-second period and moderate offshore wind – it’s surfable but ordinary. The second week, from 2 September onward, is all small, clean, but pretty much flat. The combined energy readings are mostly under 100, and often below 50. There’s a blip on Wednesday morning, 9 September, with a 5ft SW swell at 6 seconds, but combined energy is 167 and the wind is cross-shore and moderate, making it choppy – not a good look.

The final day, Friday morning, 11 September, shows a 6ft SSE swell with a 12-second period and combined energy of 843 (moderate to strong), but the wind is cross-on and the tide question is marginal. It’s a long-range prospect, so promising but less certain.

So, overall, Friday morning, 28 August, is your best bet – clean, solid groundswell with good energy. After that, it’s a long stretch of tiny surf with a few ordinary, surfable windows. The area is fairly consistent, so it won’t stay poor forever, but for now, pick your moment carefully.
