The Lowdown

Alright folks, Rusty here. Let’s take a look at what’s on offer for Narrabeen-Alley Rights over the next couple of weeks.

Straight up, I’ll be honest with you – it’s a quiet spell. The first few days are pretty flat and messy, so you’re not missing much. The real action, if you can call it that, doesn’t even start to look half-decent until the tail end of the first week, but even then, it’s more about the clean conditions than any real power.

The water temp is sitting at 65°, which is pretty much spot on for this time of year, so that’s one thing you don’t have to worry about.

Let’s start with Monday morning, September 7th. There’s a tiny 2 ft swell from the SSE, period around 10 seconds, and the wind is light off from the NNW. It’s clean, but the energy is weak (65). It’s surfable, but you’d be scratching for a ride.

The window opens up a bit on Tuesday afternoon, September 8th. Swell bumps up to 7 ft from the SSE, period 9 seconds, and the combined energy jumps to 624 – that’s moderate energy, but it’s a bit of a mixed bag. The wind is onshore, so it’s not gonna be pretty. Honestly, for a beach break, that’s more interesting for the kite crew than for paddle surfing.

The rest of the week into the weekend is a write-off. We’re looking at tiny waves, cross-shore winds, and choppy conditions. There’s a clean patch on the Sunday morning, September 13th, with a light cross-offshore breeze, but the swell is only 0.7 ft – you’d be better off on a longboard in a lake.

Now, here’s where it gets a little more interesting. We start to see a pattern of offshore winds kick in from Friday, September 18th, through to Saturday, September 19th. Friday afternoon has a gentle offshore breeze from the NW, with a 4 ft swell from the NE, period a short 5 seconds. The energy is moderate (103) but the clean conditions are a major positive. Then Saturday morning, September 19th, sees a moderate offshore from the NW again, with a 3 ft NE swell (period 7 seconds), energy at 82. It’s not huge, but it’s clean and rideable. That Saturday morning is probably the pick of the bunch – light offshore, clean face, and you might get a few fun ones.

Further out, on Monday morning, September 21st, we get a glassy session with a 3 ft NE swell, period 6 seconds, and energy of 124. It’s clean, but the swell is still short-period and weak. Again, it’s surfable, but don’t expect any barrels.

So, overall, the standout is Saturday morning, September 19th. The offshore wind and clean conditions make it the best bet for a paddle, even if the swell isn’t pumping. There’s a long gap of flat, poor quality surf before that, so don’t get your hopes up too early. The second week is a bit more promising with the offshore patterns, but those long-range calls are always a bit of a gamble.

Stay tuned, forecasts can change.

Rusty.
