The Lowdown
Alright, Rusty here, let’s talk about what’s in store for Narrabeen-Alley Rights.
Honestly, mate, looking at the next sixteen days, it’s a tough run. There’s a lot of small, messy, and wind-affected days ahead, with only a few brief windows that might offer something rideable. The surf is mostly inconsistent, so don't get your hopes up for a solid week of waves.
The best bet in the whole outlook is actually the first up: Tuesday morning, the 25th of August. We’ve got a 5ft NE swell pushing in, with a period of 7 seconds, which is a bit short-period, so it’ll be a bit bumpy, but the wind is a cross-off from the NNW at 9 mph, keeping the surface clean. The combined energy reads 356, so it’s got some moderate push. This is the standout – it’s exposed to the ENE swell, which is pretty close to the optimum direction. But remember, it’s a beach break, so it’ll be a bit lumpy, and it’s a spot that’s very consistent, so crowds are often here. The water temp is about average for the time of year, nothing unusual.
After that, Wednesday the 26th drops off. Wednesday morning has a smaller 4ft NE swell, but the wind swings to a cross-shore from the SW, and with light rain, the quality is poor. The combined energy drops to 133. Wednesday afternoon gets worse – a 3ft ENE swell, but the wind is a fresh cross-on from the S at 19 mph, making it lumpy and useless.
Thursday the 27th is tiny – 2ft with a cross-on wind, and the combined energy is down to 54 and 52. Not worth paddling out for.
Friday the 28th offers a sliver of hope. The morning has a 2ft ENE swell, but the wind is offshore from the WNW at 6 mph, so it’ll be clean. The combined energy is 59, so it’s weak, but you might get a few grovelly ones. The afternoon is blown out.
Saturday the 29th sees a pulse of 5ft SSE swell, giving a combined energy of 423, which is moderate. But the wind is a moderate cross-on from the S at 16 mph, so it’ll be choppy. Not a good session.
Sunday the 30th is a real tease. The morning is glassy – wind from the WNW at 3 mph, with a 2ft SE swell. The combined energy is 124. The water will be like glass, but the waves are small and weak. It’s surfable, but nothing special.
Then we hit a long gap. From Monday the 31st of August through to the start of September, it’s almost all tiny, poor surf. The 1st of September has a little 3ft NE swell with offshore wind, but the period is a shocking 6 seconds, combined energy of 68 – just a dribble. The 4th of September has a brief 4ft NE swell with a 6-second period, combined energy 200, and clean conditions, but it’s marginal.
The second week is even quieter. The 5th of September has a 3ft ENE swell, but the wind is cross-off, and it’s just ordinary. After that, the swell drops to 1ft for days, with the combined energy barely cracking 30-40. The 8th of September is glassy, but the swell is 1ft.
The final look is Wednesday morning the 9th of September – a 3ft ENE swell, with a gentle offshore from the NW at 9 mph, giving a combined energy of 103. It’s clean, but with a 7-second period, it’s short and weak.
Look, if you’re desperate, the Tuesday morning, the 25th of August, is your best window. After that, Sunday morning the 30th is worth a paddle for the glassy conditions, but don’t expect much. The rest of the run is a write-off.
Rusty.
