The Lowdown
Alright, Rusty here again. Let’s break it down for Narrabeen-Alley Rights.
The next few days are a total loss. Cross-onshore winds and no swell to speak of, so leave the board in the car. Water temp is about 64°, which is dead average for the season.
First chance of something decent hits on Sunday, July 19th. Swell jumps to 7ft from the east, with an 11-second period, and the combined energy is 1026 – that’s a lot of power. But the wind is onshore, so it’s a bit of a messy option, just marginal.
The real standout is Monday, July 20th. The morning is glassy, with a light NNW breeze. You’ve got a 5ft swell from the ENE, 10-second period, and 542 units of energy. That’s clean, that’s rideable, and with that offshore wind early, Narrabeen-Alley Rights is going to be offering up some proper lines. It’s a beach/sandbar, so it can be a bit fickle, but with that swell direction and period, it’ll be good. Expect some company, as it’s often crowded.
Tuesday morning, July 21st, still has that 5ft swell and a light cross-offshore breeze, energy at 499 – still clean and fun. Wednesday morning, July 22nd, holds with a 5ft swell and clean conditions, but the energy drops to 373.
Then, Thursday, July 23rd, is a cracker. Morning brings a 6ft swell from the east, 11-second period, and a gentle offshore from the WNW. That’s 737 units of energy and a “very good” call. That’s a serious day if the bank holds.
After that, the swells fade through the end of the month. You get some clean mornings, but the waves drop to 2ft by the 30th, and the energy falls into the double digits. It’s a waiting game after that first week of action.
Best bet: the Monday morning glass-off on July 20th, with Thursday the 23rd as a close second.
Rusty.
