The Lowdown
Righto, let’s have a look at what’s on the cards for the next couple of weeks at Narrabeen-Alley Rights.
The next week and a bit is going to be a bit of a flat spell, with nothing doing. We’re looking at a run of small, weak, and messy conditions with the swell energy barely registering. There’s a gap of about ten days where there’s not much to get excited about. You’ll see a tiny pulse on the 30th, but it's under 3ft and pretty ordinary, so it’s not worth rushing out for. The wind does swing around to the west and north-west at times keeping the critters clean, but with the swell being so small, the sandbar just won't have any push.
The first real highlight of the window shows up on Friday morning, the 28th. It’s still a week out, so treat it as promising rather than locked in. Overnight a south-southeast swell fills in, and it’s a solid jump in energy. This is the standout period. The swell is up to 6ft with an 11-second period – real groundswell – and the wind is a light westerly making it glassy. This is where your eyes should be.
That Friday morning is the pick, and the best of the lot as far as I can see. The water temperature is 64°, which is pretty much average for this time of year, so a decent 3/2mm steamer will do the trick.
So, the plan is to save your energy for that Friday morning session. It's got the size, the period, and the glassy conditions that make this place fire. Get on it.
