The Lowdown
G’day, this is Rusty. Let’s have a look at what’s cookin’ for Narrabeen-Alley Rights over the next couple of weeks. I’ll be straight with you – it’s a bit of a rough stretch. There’s no good surf to start, and we’re lookin’ at a long dry spell before anything half-decent shows up.
Right off the bat, it’s a flat, poor affair. Saturday the 5th has a tiny 3 ft NE swell with a period of just 5 seconds and a cross-off breeze, but wave energy is weak at only 38 – honestly, it’s barely worth a paddle. The whole first week is a write-off with swells barely above 2 ft, short periods, and wind mostly onshore or cross-shore chopping things up. There’s a moment Monday the 7th morning when it goes glassy, but the swell is a pathetic 0.7 ft – just flat. That pattern holds right through to the 15th: lots of cross-on winds, periods under 10 seconds, and combined energy mostly under 100. This break is exposed to ENE swell, but we aren’t gettin’ any love from that direction in decent size.
The only glimmer in this whole 16-day window comes on Saturday the 19th in the afternoon. Finally, we get a 3 ft SSE swell with a period of 10 seconds, combined energy of 166 (moderate), and a clean offshore breeze out of the NNW. The water temp is about average for this time of year, sittin’ around 64°. It’s still small – not a standout by any stretch – but it’s the best we’ve got. You’ll have the place mostly to yourself since crowds are often a thing here, but with the tiny size, it might not be too bad. Keep your expectations low, mate. After that, the 20th fades back to tiny, clean but near-flat.
So yeah, this is a long, slow grind. Best bet is that Saturday afternoon the 19th, but it’s more of a fun-sized micro session than anything to write home about. Hang in there – forecasts can shift.
Rusty.
