The Lowdown

G’day, Rusty here, and let’s talk about what’s coming up at Narrabeen-Alley Rights. It’s a mixed bag overall, with the standouts definitely later on. The water’s sitting at 63°F, which is about average for this time of year.

We’re looking at a small, clean window first thing Wednesday morning the 19th. Swell’s a tiny 2ft from the ESE, but with the wind glassy from the north at just 3 mph, it’ll be clean as a whistle. The energy’s moderate at 201, so there are some fun little lines – not big, but worth a paddle for the advanced crew. That’s your first real go.

Wednesday afternoon the 19th, the wind swings to the NE and hits 16 mph, and the waves jump to 4ft from the east with energy at 311, but it goes cross-shore and messy. It’s a write-off.

Thursday the 20th morning sees a small ESE swell at 2ft, but the wind’s cross-off from the north at 6 mph, so it’s clean enough. Energy’s dropped to 98, so it’s weak. Later that day and through Friday the 21st and the weekend, it’s a run of really ordinary to poor conditions—tiny swell, periods under 8 seconds, and winds all over the shop. There’s a stretch from Thursday afternoon all the way through to Sunday the 23rd where there’s nothing worth jumping in for.

Monday the 24th and Tuesday the 25th, we start to see a pulse. Tuesday morning the 25th, the swell picks up to 4ft from the ENE, period 7 seconds, and the wind turns offshore from the NW at 9 mph. Energy’s back into moderate territory at 127, and the conditions are clean. It’s surfable but still just ordinary, so not a standout. The Tuesday afternoon session holds with similar size and offshore wind from the NW at 16 mph, energy at 151, but still a cross-chop messes it up a little.

From there, it gets quiet again – Wednesday the 26th through to Monday the 31st of August is a real flat spell. Swell drops under 2ft, winds get strong and cross-onshore, and the energy plummets to single digits or low double digits. There’s hardly a wave to push.

Now, here’s where it gets interesting. On Tuesday the 1st of September, a solid pulse arrives. The morning shows 4ft from the SE at 9 seconds, with light offshore north winds at 6 mph, so it’ll be clean. Energy jumps to 258 – strong and punchy. This is a true standout for the advanced crew. The south-east direction fires up Narrabeen-Alley Rights nicely, and with that period, the sets will have some real shape.

Then Wednesday the 2nd of September morning is the absolute gem. The swell is 4ft from the SSE at 9 seconds, and the wind is glassy – dead calm. Energy sits at 218. It’ll be picture-perfect, clean lines, and that optimum ENE direction is close enough to the SSE that the rights will wrap in nicely. This is the best on offer, no question. If you can only get in the water once in this whole outlook, make it that Wednesday morning.

Thursday the 3rd of September has a smaller drop-off, with 2ft SE swell and glassy conditions again in the morning, but it’s just okay, not a standout.

Overall, the real action is in that first week of September – the 1st and 2nd are the only true standouts. Everything else is either flat or messy. The gap from the 21st to the 31st of August is a long, flat run.

Stay patient, and get on that Tuesday or Wednesday morning early September.

Rusty.
