The Lowdown
Alright, surfers, Rusty here. Let's have a look at what's on the cards for Narrabeen-Alley Rights.
Straight up, the next 16 days look like a tough slog. We're staring down a long stretch of flat, small, or just plain messy conditions. There's a real gap here with no real surf to get excited about for the bulk of the forecast.
The first few days are tiny. Friday morning the 4th of September, we've got a bit of a pulse at 1ft from the NE, but with a weak period of 8 seconds and a measly 39 combined energy, it's a non-event. The wind is offshore, WNW at 3 mph, making it clean, but there's just no power. Saturday afternoon the 5th offers a slightly better looking 3ft from the NE, but with a 5-second period, it's just crumbly and weak.
The only real spike in size comes on Tuesday the 8th of September. The swell jumps to 7ft from the SSE, with a moderate 8-second period and a combined energy of 572. That's a lot of water moving around, but the wind is a cross-onshore S at 12 mph, making it a choppy, lumpy mess. This is expert territory at that size, and with the wind against it, it's going to be a battle. Honestly, with that wind and swell, this setup looks more interesting for kite surfing than paddle surfing.
The rest of the window is a write-off. We see a few days with clean, glassy conditions, like Monday morning the 7th, but with a swell of 0.7ft, it's a lake. The wind goes near gale-force from the SSE on the 18th and 19th of September, completely blowing out any hope of a wave.
To be honest, this is a blank run for Narrabeen-Alley Rights. There's no standout option here. The only thing to do is wait for the forecasts to change.
Rusty.
