The Lowdown
Alright, this is Rusty. Let's have a look at what's on the table for Narrabeen-Alley Rights.
We're looking at a bit of a slow start, but there are some solid windows worth paddling out for. The water temp is sitting right on the seasonal average at 64°, so nothing weird there.
The first real chance to get wet kicks off on Wednesday, July 22. We've got a 4ft ENE swell with a 10-second period pushing in. The combined energy is moderate at 269, and with a light WNW offshore breeze of 6 mph, the morning session is looking clean. There's a solid bit of push in those waves for an advanced crew. The afternoon goes glassy with the wind dropping to nothing, but the swell dips slightly to 4ft. This is a very consistent spot, so you'll get plenty of waves, but it's an advanced wave, so be ready.
Thursday, July 23, sees the swell drop to 3ft, and the wind is a cross-offshore from the W at 9 mph. It's surfable, but nothing to write home about. The energy is low at 119.
Then we hit a dry spell. From Friday, July 24, right through to Wednesday, July 29, the swell is tiny, mostly under 2ft with almost no energy. Don't even bother. It's a genuine gap of nearly a week of flatness.
Now, Thursday, July 30 is a standout, but it comes with a massive caveat. We're looking at a 10ft swell from the SSE with a 9-second period, and the combined energy is a massive 1526. That is a lot of water. The morning wind is a cross-shore from the SW at 9 mph. The problem is, this spot is a beach/sandbar setup, and 10ft is simply too big for it. This is for experts only, and even then, it's going to be a washing machine. If you are not seriously experienced, stay on the beach. The afternoon stays big with 10ft, but the wind goes onshore, making it even messier. This setup looks more interesting for kite surfing than paddle surfing.
Friday, July 31, drops back to a still-chunky 5ft, but with onshore wind and rain, the quality is poor.
The next real window is Saturday, August 1. The morning session is the pick of the entire forecast. We've got a 5ft SSE swell (10-second period, 538 energy) and a light offshore from the NNW at 3 mph. That's clean, glassy surf. It's a good size, so it won't be for beginners, but for the experienced surfer, this is the one to circle. The afternoon drops to 4ft, but the wind shifts cross-shore and the quality drops off.
Sunday, August 2, offers a smaller 3ft SSE swell with a light offshore in the morning. It's clean, but the energy is only 222, so it's a mellower option for a longboard or a funboard.
The run from Monday, August 3, onwards is mostly a write-off again. We get a bump of 2ft, but the wind picks up, and by Tuesday, August 4, it's a 19 mph WNW cross-offshore with a tiny 2ft swell. Not worth it. The final few days of the forecast are flat with no swell energy at all.
So, to boil it down: the best surf on offer is Wednesday morning, July 22 for a clean, solid session, and Saturday morning, August 1 for the cleanest, best-shaped waves of the whole period. Thursday, July 30, is a massive, powerful swell that is only for the brave and the expert.
