The Lowdown

G'day, Rusty here. Let's break down the next two weeks for Narrabeen-Alley Rights. It's a bit of a waiting game, with only a few windows that'll really make it worth your while.

The forecast starts off small and grovelly. Sunday morning, August 9th, we've got a tiny 3ft ENE windswell at 9 seconds, with a light NNW cross-off breeze making it look alright. The water temp is about 63°, which is pretty normal for this time of year. The energy is weak, around 168, so grab the log or a fish. Sunday afternoon is more of the same.

Monday the 10th sees a bigger pulse, with the morning showing 7ft ENE at 9 seconds and a strong offshore NW wind at 22 mph. It'll be clean, but that size puts it in the advanced-only zone. The energy jumps to 676. The afternoon cleans up but drops to 5ft from the NE with a howling 25 mph NW offshore. The waves will look perfect, but paddling out will be a proper mission.

After that, the surf dries right up. Tuesday the 11th through Friday the 14th sees tiny waves around 1 to 2ft, with weak energy in the double digits. You might find a ripple on Tuesday morning, but it's poor.

Then we hit a rough stretch from the 15th to the 19th. Small, weak swell with onshore or cross-onshore winds making a mess of things. On the 16th and 17th, we get some size back, about 5ft, but it's from the ESE with a short, crumbly 6 to 7 second period and strong cross-onshore winds. It'll be lumpy and choppy – honestly, looks more like a kite session than a paddle.

Here's the good news. Thursday morning, August 20th, finally shows some promise. A clean 5ft ENE swell at 8 seconds, with a light NNW cross-off breeze. The energy is back up to 250, and the forecast says "expect good surf conditions." Not huge, but fun and clean.

Friday morning, August 21st, is even better. The swell holds at 5ft from the ENE, but the wind goes light offshore from the NW, with a bit more energy at 262. This is your standout session. Clean, offshores, and the swell direction is perfect for the bank.

The last highlight is Sunday morning, August 23rd. Swell picks up to a clean 5ft ENE at a longer 9 second period, with glassy, zero wind from the SW. Total perfection on the surface. Energy is solid at 281. Just know that crowds are listed as "often" here, so you won't be alone.

So, in short: the mornings of Thursday the 20th, Friday the 21st, and Sunday the 23rd of August are your best bets. The earlier part of the week has the size but the wind makes it a tough paddle. Be ready for those clean windows.

Rusty.
