The Lowdown
Alright, this is Rusty, and I’ve been staring at the charts for Narrabeen-Alley Rights. It’s a beach and sandbar set-up that’s very consistent and exposed to the east-northeast. Water temp is about average for this time of year, nothing weird going on.
Honestly, the outlook is a bit of a slow burner. We’ve got a long stretch of nothing worth paddling out for. From Thursday the 16th all the way through to Saturday the 19th, it’s just poor surf with cross-onshore winds and lumpy conditions. You’re looking at weak, short-period swell – energy barely cracking 62 (62) to 217 (217) – and it’s just messy. Forget about it.
Sunday the 19th morning sees a bit of a pulse. The swell jumps to 7 ft from the ENE with a period of 11 seconds, and the energy is up at 936 (936). That’s a moderate wave energy, and the wind is light and onshore. It’s surfable, but the report says it’s marginal with questionable tide conditions. It’s not a standout, but it’s the first sign of life.
Now, Monday the 20th morning is where it gets interesting. That’s your best window. The swell is 6 ft from the ENE, period 10 seconds, with a cross-offshore wind from the west at 10 km/h. That’s clean. The energy is still strong at 571 (571). The forecast says “expect very good surf conditions” – that’s a little hint of something special. For an advanced break like this, 6 ft is solid, and with that light cross-off, the waves will be holding up. The only bummer is that crowds are often here, so you’ll have company.
Tuesday the 21st morning is still okay – 5 ft ENE, 10 seconds, and a light cross-off from the NNW at 5 km/h. It’s clean, but the energy drops to 377 (377). It’s good, but not as punchy as Monday.
After that, it fades. From Wednesday the 22nd onwards, the swell drops below 4 ft, the energy falls away, and the wind is all over the place – cross, cross-on, or just too strong. By the 24th, it’s barely 3 ft. The second week is a write-off. There’s a gap of about five days where it’s just too small or too windy. The 27th and 28th of July are glassy and clean, but the swell is a pathetic 1 ft.
So, the standout is crystal clear: Monday morning, July 20th. It’s the only time the stars align for a proper session. 6 ft ENE groundswell, light cross-off, clean faces. That’s the one. Everything else is either a gamble or a flat spell.
Stay patient, and keep an eye on the charts. This spot tends not to stay quiet for too long.
Rusty.
