The Lowdown
Alright, grab your wetties, let’s take a look at what’s on offer for Narrabeen-Alley Rights.
Mate, I’m not gonna lie – the next week and a half is a bit of a write-off. We’ve got a long, slow stretch of small, messy waves ahead. The swell energy is weak, barely cracking 100 (54) on Thursday morning, and it just drops off from there. The wind is mostly on it or cross-on, and the periods are short and weak. You’ll be sitting out there on a 1 ft to 2 ft lump with no push. It’s pretty grim.
Now, there is a little light at the end of the tunnel. Keep your eye on the Saturday of the 22nd of August. That’s the real standout in this whole run. We see a solid jump in swell from the ENE, building to a clean 4 ft on the Saturday morning, with a 9-second period. The combined energy jumps up nicely to 213, and the wind is a clean offshore from the NW. By the afternoon, it pushes up to 5 ft with a gentle offshore from the NNW and the energy hits 357. That’s proper fun size, clean and lined up. The Sunday morning of the 23rd holds in at 4 ft with the same offshore NW wind (energy 266). This is your window. It’s still not huge, but it’s the only time the whole forecast where the stars align.
Before that, we get a brief tease on Wednesday the 19th morning. A glassy 4 ft (132 energy) but it’s short-period stuff and the quality is just ordinary. Not worth rushing for.
After that Saturday and Sunday, it fades back into smaller, cleaner but weaker waves through the middle of the next week. Nothing special.
So, in short: suffer through the small stuff for a week and a half, then hit Narrabeen-Alley Rights hard on the 22nd and 23rd of August for the cleanest, funnest waves of the whole run. It’s an exposed bank, so it’ll pick up that ENE swell well, and with that offshore wind it’ll be looking crisp. It’s a very consistent spot, but it can get crowded, so expect company.
The water temp is sitting at 62°F which is about a degree and a half colder than usual for this time of year, so a bit nippy.
