The Lowdown
Alright, let’s talk about what’s brewing for Narrabeen-Alley Rights. This is a beach and sandbar break, wide open to the swell, and it can get a crowd around here.
The first real action hits Monday, July 20th in the morning. We’ve got a 6ft ENE swell ticking over at 11 seconds, with a light WNW cross-off breeze. That’s clean, strong, and the combined energy is sitting at 832 – proper moderate punch. This is the standout window. It’s an advanced wave, so not one for beginners, but for the crew that knows the peak, this is the session. Crowds are often, but on a morning like this, you’ll share the love.
Monday afternoon, the wind swings NE and picks up to 15 mph, turning cross and chopping things up. Swell drops to 6ft, energy still moderate at 752, but the quality goes downhill. Tuesday morning brings a 5ft ENE swell, 10 seconds, light north wind, still cross-off and clean – not as strong as Monday but still a good paddle out. Tuesday afternoon gets messy with a 20 mph NE breeze. Wednesday morning holds small but clean 4ft waves, and Wednesday afternoon goes glassy with a light ENE breeze – perfect for cruising on a bigger board.
From Thursday the 23rd through Sunday the 26th, it fades hard. Swell under 3ft, energy under 102, and just nothing pushing through. That’s a few days of flatness.
Monday the 27th brings a new SSE swell at 3ft and 9 seconds, clean with a light NNW wind, but only moderate energy (190) and the conditions are nothing special. Tuesday the 28th is small and offshore, but still small. Wednesday and Thursday are mostly flat.
Now the long-range look. Sunday, August 2nd, morning shows a 4ft SSE swell, 11 seconds, light SW cross-off, and clean. Energy is moderate (425). That’s a good signal, but it’s over a week away. Monday the 3rd pushes up to 6ft from the SSE, but the wind is cross-on, so a bit grotty. Tuesday the 4th, morning glass-off with 5ft SSE swell at 10 seconds and 522 energy – that’s a clean, solid option if it holds.
Water temp is about normal for this time of year, nothing crazy.
So the call is: Monday the 20th of July, morning, is your best shot. Clean, solid ENE groundswell, light offshore, and good energy. Later on, Sunday the 2nd and Tuesday the 4th of August are ones to keep on the radar.
