The Lowdown
G’day, Rusty here. Look, I’ll be straight with you—this 16-day window for Narrabeen-Alley Rights is a slow burn. For the first week, it’s mostly flat, weak, or messy. But if you’ve got patience, there are a couple of sessions that’ll make it all worthwhile.
We start off Tuesday the 28th with nothing to get excited about—tiny, weak swell with poor conditions. Wednesday and Thursday aren’t much better. The whole first week is a write-off, really. Friday the 31st, still tiny. Saturday the 1st of August sees a tiny bump of 2ft from the SSE with a 12-second period, but conditions are just ordinary. The combined energy is weak (129), so don’t bother.
Then Sunday the 2nd of August—that’s the first standout. Early morning, we’ve got 5ft of SSE swell (12-second period) with a clean NW offshore breeze. The combined energy bumps up to a solid moderate (569), and the forecast is saying very good surf conditions. This is the one to aim for. The swell direction is a touch south of the optimum but the wind makes it clean. The water temp is 65°, which is about average for this time of year, so no surprises there.
Monday the 3rd drops off a little—3ft and a cross-shore wind, only marginal. Tuesday the 4th is a write-off again with storms.
Now, the second week brings a bigger pulse. Wednesday the 6th of August in the afternoon gets messy with 7ft of SSE swell and a fresh cross-onshore wind—that’s more for kite surfers than paddle surfers. But Thursday the 7th of August morning is the real standout of the whole period. We’ve got 7ft of SE swell (9-second period) with a light offshore breeze from the N. The combined energy is strong (835), and the surf is forecast to be very good. This is solid, powerful stuff—likely too big for beginners, but for experts, it’s a ripper. The wind will keep it clean.
Friday the 8th of August morning still has good energy—4ft of SSE swell, 12-second period, clean cross-offshore breeze, and a combined energy of 675. Another good session. After that, it fades into smaller, more ordinary conditions through to the end of the window.
So, bottom line: the first week is a bust. The best two calls are the mornings of Sunday the 2nd and Friday the 7th of August. The 7th is the bigger, more powerful swell, but the 2nd has longer period and cleaner conditions. Both are worth a paddle.
Rusty.
