The Lowdown
Alright, Rusty here again. Let’s run through the same outlook but in feet and knots.
Narrabeen-Alley Rights is looking a bit sleepy to start. Sunday 19th July has a 7ft ENE swell, but that southeast wind is onshore, so it’s messy. Combined energy is strong at 1098, but the wind is trash. Sunday afternoon drops to 7ft, still onshore.
Monday 20th July is the highlight of the first week. Early morning, 7ft ENE swell, 11-second period, and the wind is glassy from the WNW. That’s a dream setup. Combined energy is 934, and the water is 64°, which is about average. The waves will be clean and lined up. Crowds are likely, so get in early.
Tuesday 21st July morning is still rideable with 5ft ENE and a light offshore, but the energy drops to 425. Wednesday afternoon sees the swell fading. By Friday 24th, it’s 1ft and energy is just 28. The weekend of 25th-26th July is flat.
There’s a gap on Monday 27th and Tuesday 28th morning, but then Tuesday 28th July morning brings a 4ft SSE swell with a very long 17-second period, light offshore wind, and 898 energy. That’s a proper groundswell, but the direction isn’t perfect for this break.
Wednesday 29th and Thursday 30th July morning see a 5ft SSE swell, 11-second period, 564 energy, and clean offshore wind. Friday 31st July holds up with 5ft SSE and a cross-offshore breeze. That stretch from Tuesday 30th to Friday 31st July is the best run.
Saturday 1st August is tiny – 0.7ft with a 19-second period. Sunday 2nd August picks up to 4ft SSE, but the wind is strong and cross-off, so it’s messy.
Monday 3rd August is a monster: 10ft SSE, 13-second period, and 3462 energy. That’s too big for this spot. Only for experts. The wind is offshore, so it’ll be clean, but the size is the problem.
Best bets: Monday 20th July morning for the cleanest session, and the run from Tuesday 30th July to Friday 31st July for consistent, clean waves. That 3.0m day on 3rd August is for the brave only.
Rusty.
