The Lowdown
G’day, Rusty here. Look, I’ll be straight with you – the next couple of weeks are a proper mixed bag. Most of the time it’s flat or ordinary, but there are a couple of moments that’ll get the blood pumping if you’re patient.
The first decent window doesn’t show up until Tuesday the 8th of September. Before that, we’ve got scraps – tiny 1 ft to 2 ft slop with a mix of light offshore and cross-off winds, but the swell energy is pathetic and the wave comment is basically “poor.” Wednesday the 2nd and Saturday the 5th offer a few clean moments, but honestly, it’s barely surfable.
Then early on Tuesday the 8th, Narrabeen-Alley Rights (beach/sandbar) wakes up. We get a 5 ft NE swell, period short at 7 seconds, with a light N breeze that’s cross-off, keeping it clean. The combined energy is solid moderate. This is a standout for the run, but that short period means it’ll be a bit crumbly. It’s a very consistent break that’s exposed to the ENE optimum, so it’ll pick up what’s on offer. Expect often crowds because the locals know their spot.
Thursday the 10th through Sunday the 13th is a grim flat spell – zero swell energy, onshore wind, just forget it. Water temp is sitting at about 64°F, which is about average for this time of year, so no surprises in the temp.
Now, Saturday the 12th throws up bigger numbers: a 6 ft SSE groundswell with a 9-second period, and the combined energy is strong. This is second-tier – big enough to be expert territory (over 5 ft) but the wind and tide make it tricky.
Monday the 14th morning is the true diamond. A 4 ft SE groundswell with a 10-second period, glassy conditions – NE wind at 3 mph, so it’s dead calm. Combined energy is moderate. This is the cleanest, most user-friendly session in the whole outlook. That 10-second period gives it shape and drive. It’s consistent, the optimum swell direction (ENE) is close enough, and with glass, you’ll have smooth faces. Crowds are likely, but for this quality, it’s worth it.
After that, it fades back to small, choppy nothingness through to Wednesday the 16th, with 3 ft to 4 ft slop and onshore or cross-shore wind.
Best on offer: Tuesday the 8th morning (5 ft NE, clean cross-off) and Monday the 14th morning (4 ft SE, glassy). The 14th is the real standout – clean, glassy, and solid chest-high.
Rusty.
