The Lowdown
Alright, mate, Rusty here. Let’s have a look at what’s on the cards for Narrabeen-Alley Rights (Sydney). It’s a bit of a slow burner, to be honest. We’ve got a long stretch of tiny, weak surf ahead, but there’s a glimmer of something a little more interesting if you’re willing to wait.
The water temp is sitting pretty much where it should be for this time of year, nothing wild there.
Right now, Monday the 31st of August, the swell is a measly 1ft from the ENE, with a period of 9 seconds. The combined energy is a weak 17, so there’s just nothing to grab onto. The morning is glassy, but it’s basically a lake. That theme continues all the way through the first week of September. Day after day we’re seeing 1ft to 1ft ENE swell, with poor conditions. The wind does offer some clean windows, like Tuesday afternoon the 1st of September with a light offshore from the north, but on 1ft surf, it’s barely a ripple. You’d be floating around more than surfing.
The weekend of the 5th and 6th of September is a write-off too. Saturday morning has a strong 22 mph offshore wind, but the swell is only 0.7ft with an energy of 8. Sunday morning is dead flat and glassy. There’s a serious gap of no decent surf here.
We finally get a pulse of moderate energy kicking in around the 12th of September. Saturday the 12th of September morning sees the swell bump up to 3ft from the east, with an 8-second period. The combined energy ticks into the moderate zone at 113. The wind is a clean cross-off from the north-northeast, so the waves should be clean. It’s still only surfable in a very ordinary kind of way, but it’s the best we’ve seen in a long time. The same holds for the afternoon.
Moving into the second week, the 14th of September Monday morning has a 3ft swell from the NE with a 7-second period and energy at 113. The wind is a light cross-off from the WSW, offering clean conditions. This is a solid contender for the best of the window. The following day, Tuesday the 15th of September, dawns with glassy conditions and a 2ft NE swell, and energy at 76. It’s clean, but still small.
The standout here is the Saturday the 12th of September. It’s not going to be pumping, but after that long flat spell, 3ft of clean, cross-off surf at Narrabeen-Alley Rights will feel like a gift. The ENE swell direction is right on the money for this spot. It’s an advanced break and it’s very consistent, but with this size, it’ll be accessible for strong intermediates. Expect crowds, as it’s often busy.
Keep an eye on the Monday the 14th of September too, as a backup. The long-range stuff is always a bit less certain, but it’s a promising window.
Rusty.
