The Lowdown
Alright, Rusty here. Let’s talk about the next few weeks at Narrabeen-Alley Rights.
Right off the bat, it’s a slow start. For the first few days, we’re looking at tiny, weak energy with nothing worth paddling out for. The swell is small, the period is short, and the wave energy is barely registering – reading at just 6 on the Sunday. You’d be wasting your time.
We’ve got a gap of about five days with no real surf to speak of. Then things start to wake up around Saturday, August 1st. The swell picks up to 6 ft from the SSE, with moderate energy (645), but it’s a bit of a messy one. The wind is cross to cross-on, so it’s not going to be clean. It’s more of a “maybe” session for the experienced crew.
The real standout comes on Sunday, August 2nd. That morning, the wind swings offshore from the NW at just 3 mph, and we’ve got a clean 5 ft swell from the SE with a nice 11-second period. The energy is solid (491). This is your best window. The water temp is sitting at 64°, which is about average for this time of year. For a beach/sandbar setup like this, that long-period groundswell can make the waves a bit straight, but the offshore wind will be the key to getting some clean, lined-up walls. Crowds are often here, so get in early.
Monday, August 3rd, also looks promising with a similar setup: 4 ft SE swell, light offshore NNW wind, and clean conditions. Energy is a bit lower (318), but still a fun morning session.
After that, the surf tapers off again. By Wednesday, August 5th, we’re back to small, weak swells and poor conditions. The energy drops to 70, and it’s just not worth it.
Looking further ahead to the second week, there’s a late pulse around Monday, August 10th. Swell jumps to 8 ft from the SSE, but the period is short (9 seconds) and the wind is strong cross-off at 15-22 mph. The energy is significant (915 to 1062), but with that much wind and a short-period swell, it’s going to be lumpy and challenging. This one is for experts only, and even then, the conditions are marginal. It’s promising but less certain this far out.
So, bottom line: if you’re keen, Sunday August 2nd and Monday August 3rd are your best bets. Clean, offshore winds, and a solid groundswell. Don’t sleep on it.
Rusty.
