The Lowdown
G’day, I’m Rusty. Let’s have a look at what’s on offer for Narrabeen-Alley Rights.
Straight up, it’s a pretty lean start. The first week or so is a real struggle, with barely a wave worth paddling for. We’ve got a long gap of poor surf from the 25th of July right through to the 31st. The swell is tiny, mostly under 1 ft, with weak energy (8 or less), and the wind is either onshore or cross-off, so it’s not doing us any favours. The water temp is sitting at 64°, which is a dead average for this time of year, nothing unusual there.
Then on the 31st of July, Friday afternoon, a big jump comes in – 8 ft from the SSE, but with a short 10-second period. The combined energy rockets up to 1129 (strong) but the wind is cross-onshore at 25 km/h, so it’s choppy and messy. That one’s a pass for me.
The first real standout is Sunday morning, the 2nd of August. Swell from the SE at 7 ft, with a nice 12-second period, so it’s a proper groundswell with some punch. The energy is 1154 (strong). The wind is offshore from the NW, light at 10 km/h, making for clean, glassy conditions. This is the best on offer – it’s a solid wave for experienced surfers. The swell direction (SE) matches the optimum ENE direction pretty well, so it should line up nicely on the sandbar. Just be aware, it’s a beach break, and with a long period, it might break a bit straight, but the offshore wind will help. Crowds are often here, so expect some company.
Another good morning is Monday the 3rd of August. Swell from the SE at 4 ft, 10-second period, moderate energy (329). Wind is offshore from the WNW, light at 10 km/h, so clean again. It’s a bit smaller, but still a fun, surfable wave.
Looking further out, Friday the 7th of August morning has 6 ft from the E, 8-second period, with 798 energy (strong) and light WSW wind at 10 km/h, cross-off and clean. It’s a solid option for the second week, though the short period means it’ll be a bit more disorganised.
The standout remains the 2nd of August morning. Get out there early for the cleanest lines.
Rusty.
