The Lowdown

Righto mate, Rusty here. Let’s have a look at what’s comin’ down at Narrabeen-Alley Rights. It’s a beach and sandbar set-up, exposed to the open ocean, so it grabs a bit of energy but it can get pretty average too.

Overall, the pattern is pretty grim for a long stretch. There’s a real dry spell from now right through until the middle of next week. Saturday the 8th and Sunday the 9th have tiny, weak energy with combined swell energy readings of just 49 and 170, so we’re talkin’ knee-high dribble at best—1 ft and 3 ft. Winds are light and cross-off on Sunday morning though, so it’ll be clean but there’s just not enough push. Honestly, not worth paddling out for.

Monday the 10th is where it gets interesting, but only for the brave. The morning bumps up to 7 ft from the ENE with a 9-second period, and the combined energy hits 688—that’s moderate to strong power. The wind is offshore out of the NW at 19 mph, so you’ll see clean, lined-up waves. But at 7 ft, this is expert territory only. It’s gonna be big and punchy on the bank. The afternoon drops a touch to 5 ft, still offshore but with a fresh breeze. This is the best on offer for the first week—standout session for advanced crew.

Then we hit a massive gap from Monday afternoon all the way through to the 19th. Days of tiny, weak swell—1.0 ft to 3 ft—with poor wind directions and onshore slop. Combined energy stays below 100 most of the time. It’s just not worth getting wet. The 16th sees a bit of size jump to 4 ft but with a cross-onshore wind and 8-second period from the SSE, it’s messy and lumpy. Kite surfers might get a look, but for a paddle surfer? Forget it.

The real standout arrives on Thursday the 20th of August. Morning session brings a solid 6 ft of ESE swell, combined energy at 764, with a light cross-off north wind at 6 mph. That’s clean, powerful, and well-shaped for a beach break. That period is 8 seconds so it’s a mix of ground and wind swell, but the quality should be there. The morning is the pick—crowds often get in at this spot, and with conditions that good, expect plenty of company. The afternoon goes cross-shore and loses the clean factor.

Friday the 21st still has some juice—5 ft in the morning, combined energy 220, and light cross-off NNW wind. It’s clean and rideable, but not the standout the 20th is. Saturday the 22nd picks up a bit again but the wind turns cross in the arvo, so get on it early if you’re keen.

Water temp is around average for this time of year, no real anomalies to speak of. Just your standard late-winter cool.

Best standout: Thursday morning, 20th of August. 6 ft ESE, clean light winds, decent power. That’s your window.

Rusty out.
