The Lowdown
Alright folks, Rusty here. Let’s have a look at the forecast for Narrabeen-Alley Rights.
First off, I gotta be straight with you – the next week and a half is looking pretty grim. There’s a long stretch of tiny, wind-affected slop, and we’re not getting a proper surfable window until the middle of the second week. The water temp is sitting right around average for this time of year at 64°, so no complaints on the wetsuit front, but you’ll be doing a lot of waiting.
The first real chance of something decent doesn’t roll in until Wednesday morning, September 9th. We’ve got a 5ft SSW groundswell, with a period of 10 seconds, pushing in from the south-southeast. The wind is light and offshore from the WNW, so the face should be clean. Combined energy is moderate at 398, giving it a bit of push. It’s not a massive day, but after all the flatness, it’ll feel like a gift. The mid-week window is brief though, because the afternoon gets ruined by a fresh SSE cross-onshore.
The standout, and the one you should circle on the calendar, is Monday morning, September 14th. The swell jumps up to 6ft, again from the SSE, with a period of 7 seconds. The wind is a light northerly, keeping it clean and cross-offshore. The combined energy hammers up to 383, which is a solid, punchy amount of power. This is a proper, fun-sized day for Narrabeen. This is an advanced break, so it’s not for learners – 6ft is pushing it for beginners, but for the experienced crew, it’s going to be firing. Expect crowds here, because it’s a very consistent spot, and when it’s this clean, everyone knows.
Tuesday morning, September 15th, is a write-off, with a southerly wind making a mess of a 6ft SSE swell. The energy is high at 695, but it’s just too lumpy to enjoy with a paddle board – this one’s more for the kite crowd.
The final little window of hope is on Saturday morning, September 19th. It’s only 3ft from the NE, but the wind is dead calm, absolutely glassy. Period is short at 7 seconds, so it won’t have much grunt, but if you want a longboard or a log, and you just want to be out there with no wind, that’s your session.
So, to sum it up: the first week is a bust. The real action is the Monday morning of the 14th. That’s the pick of the pack. The Wednesday morning of the 9th is a decent warm-up. Don’t bother with the rest.
Rusty.
