The Lowdown

G'day, I'm Rusty, and I've got the surf outlook for the Narrabeen-Alley Rights (Narrabeen-Alley Rights) stretch. We're looking at a pretty quiet run for a while, so let's get into it.

The next week and a half is mostly a write-off, with only a few fleeting moments that might get your hopes up. The real standout is a long way off, on the 30th of August, but it's a beast that will only be for the brave.

Alright, starting off: Saturday the 15th is a no-go – tiny 1 ft swell from the ENE with a weak energy of 17, and a bit of rain and cross-shore wind. Sunday the 16th through to Tuesday the 18th doesn't look much better, with poor surf conditions and onshore or cross-onshore winds keeping things messy. The swell is small, around 3 ft, but the period is short and the energy is low to moderate at best.

There's a glimmer on Wednesday the 19th morning. The forecast shows clear skies, a glassy offshore wind from the NW at 3 mph, and a 2 ft swell from the ESE with a decent 10-second period. The combined energy is 211, which is moderate. The water is sitting at 62°F, which is a bit colder than normal for this time of year. It's not epic, but it's the cleanest we'll see for a while. The afternoon gets a bit lumpy with a cross-shore wind.

From Thursday the 20th right through to the 29th, it's a long stretch of poor to ordinary surf. The swell stays small, mostly under 3 ft, and the wind is all over the shop – cross, onshore, and at times strong. There are a few mornings with clean conditions and offshore winds, like on the 21st (Friday) and the 23rd (Sunday), but the swell is just too small to get excited about. The energy is weak, often below 100.

Now, the one that stands out is Sunday the 30th of August. The forecast is for a solid 10 ft swell from the SSE, with a long 11-second period. That's a huge amount of energy, with readings of 2390 in the morning and 1762 in the afternoon. However, the wind is onshore from the SE at 9 mph, and the comments say it's predicted to be too big for this break. This is expert-only territory, and even then, the onshore wind will make it a messy, powerful beast. It's a long-range call, so it's promising but not certain.

To sum it up: the best clean surf on offer is the Wednesday the 19th morning session, with small, glassy waves. The only real standout, in terms of size, is the 30th of August, but that's a big, onshore swell only for the experts. The rest of the forecast is a blank run of small, poor conditions.

Rusty, signing off.
