The Lowdown
G’day, it’s Rusty here.
Honestly, the next couple of weeks are a bit of a write-off for Narrabeen-Alley Rights. We’ve got a long stretch of small, messy, and onshore conditions ahead. The water’s holding at about 64°, which is pretty normal for this time of year. For the first week or so, we’re looking at tiny waves, mostly under 3ft, with a lot of cross-shore and cross-onshore wind. The energy is weak – we’re talking values in the low teens to maybe 70s at best, which is nothing to get excited about. There’s a brief moment on Saturday the 12th morning with glassy conditions and a tiny 0.7ft swell, but it’s not really rideable. Sunday the 13th and Monday the 14th have a bit of clean, light wind, but again, the swell is just too small. The combo energy is still weak, under 100.
The first real sign of life shows up on Tuesday the 15th afternoon when that southerly change pushes through. Swell jumps a bit to 4ft, but it’s straight onshore and the energy only reaches 134, which is moderate. It’s going to be lumpy and chopped up – not worth paddling out for. Conditions stay poor through the rest of that week, with fresh southerly winds and more small, messy surf. The energy stays weak, mostly in the 20s and 40s.
Now, here’s the one to circle on your calendar. Wednesday the 23rd of September, first light. We finally get some proper swell. The morning shows 5ft from the NE with an 8-second period, and the combined energy jumps to 279 – that’s moderate but the best we’ve seen by far. More importantly, the wind is light and offshore from the north, which means clean, groomed lines. This is the standout of the whole run. It’s not a massive day, but it’ll be the most surfable and fun the beach has looked in two weeks. The afternoon still has decent 3ft NE swell with 244 energy, but the NE wind picks up and goes cross-shore, so the morning is the window.
After that, it fades quickly. Thursday the 24th drops back to tiny leftovers – 1ft and less. We’re done again.
So, to sum it up: a long, flat, and frustrating stretch until Wednesday morning the 23rd. That’s your one shot. Be there early, bring the single fin, and enjoy the cleanest waves we’ll have seen in a while. It’s promising, but it’s a week and a half out, so keep an eye on it – long-range calls can change.
This is Rusty, signing off. See you in the water.
