The Lowdown
Alright, Rusty here again, but this time in feet and knots for those who think in the old numbers.
First thing’s first: the first week is a total dud. Flat, choppy, onshore junk. No reason to even wax a board until the 19th of July, and even then it’s just barely surfable.
Sunday morning, 19 July brings a 6ft east-northeast swell with a 10-second period and a light onshore breeze. Moderate energy (574). It’s marginal – tide and quality issues. The afternoon pushes it to 7ft from the same direction, period now 11 seconds, energy up to 891. Still light onshore. It’s a tease, not a standout.
Monday 20 July is similar: 6ft east-northeast, 10-second period, light cross-onshore turning to light cross. Energy moderate (574 to 606). Surfable but nothing special.
Now, the big one is Thursday morning, 23 July. We’ve got a 5ft east swell with a very long 14-second period – that’s real groundswell. Combined energy is strong at 936. And the wind? Light west, clean cross-offshore. For Narrabeen-Alley Rights (Sydney), that’s about as good as it gets on a beach break. The water temp is 65°F, right on average for the season. This break is very consistent and advanced-level only. Expect crowds – it’s a popular spot, especially with conditions like this. The morning is the pick; by afternoon the wind shifts east-northeast and it gets a bit cross and chopped.
Friday 24 July morning is still good but smaller: 5ft east swell, 11-second period, moderate energy (563), light west-northwest cross-offshore breeze. Clean again.
Then it all falls apart. From Saturday 25 July onward, a strong southerly change brings gusty cross-onshore winds and lumpy, messy surf. Swell stays around 6ft to 5ft but it’s ugly, and by the end of the month it drops to 3ft or less with onshore crap.
The standout is clear: Thursday morning, 23 July at Narrabeen-Alley Rights – 5ft east swell, 14-second period, light west offshore, clean and powerful. That’s your session.
Rusty.
