The Lowdown
G’day, I’m Rusty. Let’s talk about what’s happening at Narrabeen-Alley Rights over the next couple of weeks.
Alright, I’ll be straight with you: this sandbar is looking pretty flat and lifeless for most of the 16-day forecast. You’re looking at a whole lot of tiny, messy waves, with only one real pulse of size coming way down the track. The best bet is a standout on Friday, August 14th. We’ve got a 6ft swell from the NE, with a moderate combined energy of 525. That’s a solid size for this spot, but it’s got a 9-second period, so it’s a short-period wind swell, not a deep groundswell. The water is sitting at 63°, which is about 1° cooler than the long-term average for this time of year – a bit chilly, but not extreme. The wind on Friday morning is a gentle cross-onshore breeze from the south at 9 mph, which will put a little texture on the face, but it’s still rideable for the advanced crew. This is an exposed sandbar, so with that size, it’s strictly for experienced surfers. Crowds are often an issue here, so don’t expect a quiet session. The swell is coming from the NE, and the optimum direction for this break is ENE, so it’s close but not a perfect fit.
Before that, there’s a long, slow grind. From Sunday, August 2nd, through Thursday, August 13th, it’s mostly below 3ft, with only a couple of brief moments of 3ft to 5ft that are let down by poor conditions. Monday, August 3rd morning has a clean 3ft from the SE with a cross-off breeze, but it’s a one-off and the energy is very low at 240. The rest of that week is a write-off of tiny, messy surf, with strong cross-off winds on the 5th and 9th that just don’t deliver any quality.
After the Friday the 14th pulse, it drops back to tiny, poor surf again, with a few waist-high, ordinary waves on Monday, August 17th, but nothing to get excited about.
So, if you’re an advanced surfer and you’ve got patience, keep an eye on Friday, August 14th for the biggest swell of the window. It’s a long-range call, so treat it as promising but not a sure thing. For the rest of the time, the board stays in the car.
