The Lowdown
Righto, let’s have a look at what’s on the table for Narrabeen-Alley Rights. This is a beach/sandbar setup that’s very consistent and exposed to swell, so it usually gets something. But lookin’ at the next 16 days, honestly, it’s a pretty grim run. The first surf recommendation doesn’t pop up until Monday the 21st of September, and even then, it’s a marginal call. That’s a solid gap of near enough 12 days with nothin’ worth paddlin’ out for. The consistency here is usually your friend, but not this time – the whole period is plagued by tiny, weak swell and poor conditions.
The earliest real whiff of anything happens on Monday the 21st of September afternoon. The SSE swell hits 7ft with a period of 10 seconds, and the combined energy is a hefty 704. That’s strong wave energy, no doubt. But the wind is a moderate cross-shore, and the forecast is marginal, so it’s not a total write-off for a strong paddler. The swell direction is SSE, which is not the optimum ENE for this spot, so it’ll be a bit lumpy and fat. Still, 7ft is in that expert-only zone for beach breaks, so only the crew with the big quiver and the right tide knowledge should be lookin’ at it.
The following Tuesday the 22nd has a bit more on offer. Morning sees a NW wind blowing offshore, clean, with 4ft of NE swell (period 6 sec). Combined energy is moderate at 153. That’s much more manageable, though the short period means it’ll be a bit soft and crumbly. The afternoon bumps up to 6ft from the NE, with a cross-offshore wind and clean conditions. Energy jumps to 238 (moderate). That’s the standout of the whole outlook – it’s the best balance of size, clean wind, and a direction that roughly matches the optimum. You’ll want a bit of grunt for that size, but it’s the pick of a very poor bunch.
Everything else before that is tiny – most mornings you’re lookin’ at 0.7ft to 2ft, with weak energy readings under 100 (sometimes as low as 6 or 8). The wind is often cross, cross-on, or onshore, and the water temps are about average for the time of year. For a spot that usually fires, this is a real bummer. If you’re a kiter, you might find some fun on the bigger, windier afternoons, but for a surfboard, it’s a long wait for a couple of brief windows.
